Executive summary

The Health Star Rating (HSR) system, an interpretive front-of-pack nutrition labelling scheme, was introduced in Australia and New Zealand in June 2014. The HSR aims to provide convenient, relevant, easily understood nutrition information and/or guidance on food packs to assist consumers to make informed purchases and healthier eating choices. A secondary objective of the system is to encourage food manufacturers to reformulate their products to achieve a higher star rating.

The National Heart Foundation was engaged to monitor the implemenatation of the HSR system in Australia. By using targeted evaluation questions, this report provides an overiew of the progress of implementation of the HSR system at Year 4 (July 2017 – June 2018).

AoE1: Label implementation and consistency with the HSR system Style Guide

What is the uptake of the HSR?

Industry participation in the HSR system has increased since implementation. In Year 4, 5,448 products, or 30.5 percent of eligible products displayed the system, which was an increase of 51.9 percent from Year 3. The Confectionary HSR Category had the greatest number of products displaying the HSR system graphic (n=366) followed by Sugar (or artificially) sweetened beverages (n=314). However, the system was displayed on the greatest proportion of products in the Hot cereals – flavoured HSR Category (95%).

When uptake was weighted by sales, it showed that market penetration of HSR products was greater than what raw (unweighted) uptake may indicate. In Year 4, sales weighted uptake was 37.9 percent of eligible products which was statistically larger than raw uptake, suggesting that products participating in the HSR system are more frequently purchased than non-HSR products.

Large retailers and manufacturers were identified as key drivers of growth as private label retailers accounted for over half of all products participating in the HSR system.

Do manufacturers comply with the HSRC and guidelines?

Industry compliance with the HSR Stye Guide increased overtime, reaching 95.8 percent in Year 4. The proportion of products that have a design or technical variation has decreased since Year 2 and were at their lowest in Year 4.

However, alignment between the displayed star rating and the calculated HSR has declined over time from 98.1 percent in Year 1 to 89.7 percent in Year 4. Misalignment between the calculated HSR and that displayed on pack has been driven by both under and overstatement of the HSR, with the difference largely restricted to 0.5 stars.


AoE2: Consumer awareness and ability to use the HSR system correctly

Are consumers aware of the system?

Consumer awareness has steadily increased since the implementation of the HSR system. Unprompted awareness of the HSR increased by 61.8 percent, from 12.5 percent in Year 2 to 20.2 percent in Year 4. Prompted awareness had also increased overtime. By Year 4, more than four in every five (83.3 percent) consumers were aware of the HSR system.

Do consumers trust in the HSR system?

By Year 4, almost six in every ten consumers trust the system (58.4 percent), and even more find it credible (61.5 percent). There was recognition that the HSR provides a quick and easy reference on the healthiness (or otherwise) when buying a product.

Confidence in the HSR system also grew significantly over the three years. The majority of consumers in Year 2 were not confident in the system however; confidence had increased to over half (51.4 percent) in Year 3 and continued to almost 70 percent in Year 4.

Do consumers find the HSR system useful?

The HSR system is intended to make it easier for consumers to compare products and make healthier choices. While over three quarters of consumers (76.8 percent) agree that the HSR system makes identifying healthier products easier, 28.2 percent of consumers don’t feel the HSR adds value and reports that it makes shopping confusing.

Do consumers understand how to use and interpret the HSR?

By Year 4, when unprompted, more than half of consumers (55.8 percent) understood that the HSR provides a rating on the healthiness of the product upon which it appears. Seven in every ten consumers (72.3 percent) agree (or strongly agree) that the system makes it easier to compare products participating in the HSR system.

Though comparisons should only be made between similar products, more than half of consumers in Year 4 (58.2 percent) believed that the HSR can be used to compare products of different categories (HSR Category). However, during the focus groups, participants exhibited an intuitive understanding that the HSR can only be used to compare similar products.

Which HSR logo do consumers prefer?

A food manufacturer or retailer has the choice of five different options to use when displaying their products’ star rating. The options follow a hierarchy where Option 1 provides the greatest amount of information to Options 2 to 4 which includes decreasing amounts of information on nutrients down to Option 5, which only includes the energy icon.


In Year 4, consumers preferred Option 1 the most (63.3 percent) followed by Option 4 (21.1 percent). Consumers indicated they preferred Option 1 because it provides the most detailed information, while those that preferred Option 4 do so because it is simple.

However, there is limited alignment between what HSR logos consumers prefer to see on packs, and what manufacturers place on packs. By Year 4, the majority of consumers preferred Option 1, however Option 4 was the most common logo displayed.

Does the HSR influence consumers to make healthier choices?

In Year 4, 70 percent of consumers reported purchasing a HSR product in the last three months with nearly two thirds reporting that the HSR had influenced their purchasing behaviour.

Of those influenced by the HSR system, more than 50 percent stated that they selected a healthier product.

Overall, 23.4 percent of all consumers changed their purchasing behaviour by selecting a HSR product with more stars.

AoE3: Nutrient status of products carrying a HSR system label

Has the HSR system had an impact on reformulation?

The propotion of products displaying a lower HSR value has increased with the average HSR decreasing from 3.8 in Year 1 to 3.4 in Year 4. Correspondingly, the average content of saturated fat, sodium and sugar (per 100g or 100mL) were higher in Year 4 than Year 1.

Though a decrease in the average HSR throughout the years and increase in average content of certain negative nutrients was observed, it was important to determine whether HSR products have reformulated over time. To ascertain whether a decrease in nutrients is unique to HSR products, or reflects a general trend of reformulation, nutrient content of non-HSR products were also analysed. Results revealed that there were statistically significant reductions in energy and saturated fat content from products displaying the HSR system, compared to products not displaying the system. Therefore, participation in the HSR system may be leading to voluntary reformulation of products to decrease negative components.

Conclusion

At the commencement of the HSR system in June 2014, no specific targets for industry uptake or consumer use or understanding were established. However, monitoring data indicates that across almost every evaluation question, the monitored indicators generally have improved over the four years.

Uptake and participation in the HSR system has increased, participating manufacturers and retailers have largely complied with system guidance and there is some evidence that the HSR system is encouraging positive reformulation.

From a consumer perspective, there is strong awareness of the HSR, and majority trust the system and understand how to use it. There is also evidence to suggest that the HSR system is changing purchasing behaviours and helping consumers make healthier choices.


Chapter 1: Introduction

1.1. Context and background

In 2002 mandatory nutrition labelling was introduced for all manufactured goods sold in Australia and New Zealand. Standardised nutrition information panels (NIPs) must include the average quantity per serve of energy, protein, total fat, saturated fat, carbohydrate, sugars and sodium as well as any other nutrition informationm about which a claim is made.

While the NIP provides comprehensive information to assist consumers in making informed choices about the food they eat, it is often considered too technical and difficult to understand.1

In 2011, in response to Recommendation 50 of Labelling Logic, The Review of Food Labelling Law and Policy (2011), the Legislative and Governance Forum on Food Regulation (now known as the Australia and New Zealand Ministerial Forum on Food Regulation) agreed to the development of an easily understood, interperative front of pack labelling (FoPL) scheme for packaged food products. In partnership with industry, public health and consumer groups, the Australian, state and territory governments developed the Health Star Rating (HSR) system, which was introduced from June 2014.

The HSR system leverages much of the information that is provided in the NIP and summarises it to provide an overall nutritional rating of the product. Products are rated from half a star to five stars, providing consumers a quick, easy and standard way to compare similar packaged foods.

Participation is voluntary, with food manufacturers and retailers free to participate in the HSR system at any point by using the HSR calculator to determine the HSR for their product and selecting an approved logo to display their star rating. There are no applications or fees for participation.

Though participation in the system is voluntary with no application fee, the Health Star Advisory Committee (HSRAC) is responsible for overseeing the monitoring and evaluation of the HSR system.

1.1.1. HSR calculator

The HSR calculator (HSRC) is a tool to assist industry in determining the appropriate number of stars for their product. The HSRC takes into account energy, saturated fat, sodium, total sugars, fruit, vegetable, nut and legume (FVNL) content, and in some instances dietary fibre and protein of the product.

The HSRC comprises of two components: baseline points, consisting of negative components (energy, saturated fat, sodium and total sugars) and modifying points consisting of the positive components (FVNL content and in some instances protein and fibre). Together with the baseline points and the modifying points, a final score is calculated.

Final score = baseline points – modifying points

The final score, in conjunction with the correct HSR Category Class of the product, is used to determine the star rating of the product (see Table 1).

1.1.2. HSR system graphics

A food manufacturer or retailer has the choice of five different options to use when displaying their products’ star rating. Option 1 provides the greatest amount of information, including the energy icon, three prescribed negative nutrients, and an optional positive nutrient icon. Options 2 to 4 include decreasing amounts of information on the nutrients, down to Option 5, which only includes the energy icon (see Table 2).

Given there are five options to use, not all options may be available for food products to display. That is, a product with little nutritional value cannot display Option 1 as the optional nutrient displayed is to comply with nutrient content claims underpinned by the Food Standards Code (FSC).

While food manufacturers are free to select the HSR logo that is most appropriate for their product based on available pack size and label space, they are encouraged to use as many elements of the HSR system graphic as possible. That is, if there is enough space, manufacturers should select Option 1 over any other option, as it provides the greatest amount of information.

1.2. Monitoring and evaluation of the HSR system

The primary objective of the HSR system is to provide convenient, relevant, easily understood nutrition information and/or guidance on food packs to assist consumers to make informed purchases and healthier eating choices.2

To achieve this objective, it is necessary that manufacturers participate in the system and comply with the tools and guidelines, and that consumers are aware of the system and how to interpret the HSR.

A secondary intention of the system is that it encourages food manufacturers to reformulate products to achieve a higher star rating3. In doing so, the HSR system aims to provide greater transparency to the consumer on how similar products compare healthwise.

The monitoring and evaluation framework capture these elements in its three areas of enquiry:

Area of enquiry 1 (AoE1): assessing uptake of HSR, implementation of HSR against Style Guide, and comparing HSR displayed on pack to HSRC;

Area of enquiry 2 (AoE2): reporting on consumer awareness and understanding of HSR, accurate use of the HSR and trust in the system;

Area of enquiry 3 (AoE3): measuring the nutrient status of products participating in the HSR system and monitoring changes in the nutrient profile over time.

These three areas of enquiry were established and endorsed by the HSRAC, who is responsible for overseeing the monitoring and evaluation of the HSR system, amongst other things.

1.2.1. Program logic

The areas of enquiry are reflected in the program logic which outlines the sequence of steps required to achieve the objective of the HSR system (see Figure 1).

1.2.2. Reporting to date

The Heart Foundation was engaged to monitor and evaluate the HSR system in Australia in May 2015. Since this time, monitoring and evaluation of the HSR has included:

Eight reports on cumulative participation in the HSR system since 2015, complemented with seven point-in-time snapshots of participation in the HSR system, and annual reports on compliance with Style Guide and HSRC, addressing AoE1;

Eight surveys of consumers, and one survey of industry for AoE2;

Two reports analysing nutrient status of HSR products for AoE3; and

Two annual reports (Years 1 and 2), reporting on all three areas of enquiry.

In parallel to the monitoring and evaluation undertaken by the Heart Foundation, a review of progress was undertaken in 2016 and a five-year review by MP Consulting is currently in progress.

This report combines much of the data collected since 2014 to provide a comprehensive assessment on the progress of implementation, and evaluation of outcomes achieved to June 2018. Results from previous surveys can be obtained from here .

Chapter 2: Monitoring and evaluation methodology

This section sets out the methodology that is used to conduct the monitoring and evaluation of the HSR system. In the first section a conceptual framework is outlined to demonstrate how the consumer is affected and influenced by the HSR. This was then used to develop an overall evaluation framework.

The final sections of this chapter include the data sources and evaluation tools.

2.1. Conceptual framework

As outlined by the program logic, data collection, analysis and reporting have been structured around the three areas of enquiry. This structure has provided a convenient framework for collecting data and reporting on implementation.

In this report we expand beyond monitoring implementation to also evaluate outcomes. To this end, we leverage the literature to develop a conceptual framework illustrating the components necessary for nutrition information to affect consumer decision making.4 This is illustrated in and shows that awareness is the first and necessary condition that must be met if the HSR system is to have any impact upon the actions of consumers. The second component is attitude formation with the third looking at how attitude formation impacts upon consumer decisions.

2.1.1. Attitude formation

We make thousands of decisions every day – most of them unconsciously. To simplify decision making, people have created cognitive short cuts,5 which are often based on positive or negative associations with groups of ideas. Attitudes help to form these short cuts and therefore, are incredibly important in understanding whether consumers are positively or negatively disposed to the HSR system.

Attitude formation comprises of four elements: trust or credibility in the HSR system, understanding of the system, relevance of the system, and whether the logo is liked.6 In this report, like has been measured through consumer preferences of HSR logos and will therefore be reported as preferred.

Trust in the HSR system is a crucial element of attitude formation, because without it, consumers will be hesitant to make a purchase based on a products’ participation in the system (hereafter referred to as HSR status),7 that is whether they are displaying a HSR system graphic or not. Similarly, without an understanding of the HSR system (perceived or genuine), or perceived usefulness, a consumer is unlikely to decide to purchase a HSR product because of its participation in the system.

Another effect on the attitude formed to the HSR system is how well the label is liked and which labels consumers preferred. Preference is an important and separate component to understanding, because preference for a logo can lead to a more positive evaluation of the HSR system, even when it is not understood.8

2.1.2. Decision making

Based on the attitude formation, a consumer typically decides whether to purchase a product. However, it is possible that a person will choose to purchase a HSR product with no regard for the products participation in the system, that is whether it is displaying a HSR system graphic or not. It is therefore important to understand whether the products’ participation in the system has influenced the purchase.

2.2. Evaluation framework

The conceptual framework presented above outlines the elements necessary to determine whether the HSR influences consumers’ decision to purchase a HSR product. However, the evaluation is broader than this. The evaluation also includes monitoring implementation and evaluating outcomes beyond those associated with the consumer, i.e. uptake and correct use by manufacturers and retailers.

Evaluation questions have been developed to address each component of the evaluation: monitoring implementation and evaluating outcomes. The questions, and how they relate to each component of the evaluation is illustrated in Figure 3.

For each of these evaluation questions, detail on the methodology for measuring activities or impact is outlined, including data sources and/or collection tools used.

2.2.1. What is the uptake of the HSR?

As there is no requirement for retailers or manufacturers to inform or notify a central body or agency (e.g. Department of Health) of their participation in the HSR system, the number of products participating in the HSR must be directly observed.

The FoodTrack™ (refer to section 2.3.1) database facilitates this by collecting the HSR status of products.

To understand how the number of products participating in the HSR compares to the number of eligible products in the market, HSR coverage is calculated by dividing the total number of participating products by the total number of eligible products. This is provided on an annual basis.

To further contextualise participation of HSR in relation to consumption of food products, FoodTrack™ uptake data is weighted by Nielsen sales data (refer to section 2.3.2), where sales data acts as a proxy for consumption. The purpose of weighting is to reflect that some products have more influence on people’s consumption than others.


2.2.2. Do manufactures comply with the HSRC and guidelines?

The HSR system is self-regulated, with manufacturers and retailers responsible for correctly using the available tools to determine their star rating and apply to their product packaging.

Specifically, the HSRC in conjunction with the Guide for Industry is used to determine a product’s star rating and the Style Guide for guidance on what HSR logo to use, and how to apply it to the product’s packaging.

In Year 1 and 2, when there were 363 and 2,021 products respectively participating in the HSR system, all products were assessed for compliance. However, as participation in the HSR system grew, a sampling approach was taken. Since Year 3, annually a sample of 500 products had their HSR independently calculated to determine whether manufacturers are correctly calculating their HSR. Similarly, a sample of 500 products had their compliance with the Style Guide assessed using the Style Guide checklist.9

A product is deemed non-compliant against the HSRC when the calculated HSR is higher or lower than the HSR displayed on pack.

On the the other hand, non-compliance with the Style Guide can come from specific design or technical variations, but it is important to note that a design or technical variation does not automatically imply a product is non-compliant.

Design variations are those that don’t change the meaning of the HSR system graphic, such as a product displaying a combination of HSR system graphics on the front of pack (FoP) or using old versions of the HSR system graphic.

Conversely, technical variations change the meaning of the HSR system graphic and/or content. Examples include not placing the HSR logo on the front of the pack, mismatch in the energy/nutrient values displayed on the logo and the NIP and the nominated reference measure (NRM) differing to the guidelines.

2.2.3. Are consumers aware of the HSR system?

Through the HSR survey tracker (see section 2.4.3), prompted and unprompted awareness of the HSR system has been measured regularly since 2014.

Prompted awareness measured consumer awareness of the HSR system with prompting or assistance. It consisted of directly surveying consumers whether they were aware of the HSR system or not.

Whereas unprompted awareness measured a consumer awareness without any reference to the HSR system or assistance. Therefore, consumers were surveyed with an open-ended question asking which food logos helped them choose to buy food in the supermarket and consumers were assessed whether they were able to recall the HSR system. The unprompted awareness measure is a better and more valuable indicator of awareness rather than prompted awareness as it indicates there is a stronger impression of the HSR system that has registered in the consumers mind/thoughts.

2.2.4. Do consumers trust in the HSR system?

Consumer attitudes and perceptions of the HSR system are obtained through the HSR Tracker. Explored in detail are consumers’ trust and credibility in the HSR system.

9 See Appendix A for Style Guide Compliance Checklist


To gain further insight into why consumers hold the views they do, the findings from the survey will be supplemented with the findings from the focus groups (see section 2.4.5).

2.2.5. Do consumers find the HSR system useful?

A system that is not deemed relevant is unlikely to engage consumer interest or trust. Consequently, consumer views on whether the HSR system is, or is not useful are explored through the HSR Tracker.

2.2.6. Which HSR logos do consumers prefer?

Consumer opinions of the logo play an important role in influencing consumer attitude towards the HSR system. The presentation of the information can also impact a consumers’ ability to understand and interpret the information on the logo.

Overall preference for HSR logos is assessed by considering which of the HSR logos consumers preferred the most through the HSR Tracker, with a focus on specific attributes of the logos. Specifically, consumers’ views on the ease of understanding the logo, ability to recognise the logo, and the volume of information communicated by the logo was of interest.

Consumers views are contextualised with information from FoodTrack™ on the logos used by manufacturers and retailers to ascertain whether there is alignment between what manufacturers use and what consumers prefer.

2.2.7. Do consumers understand the HSR?

Consumers’ understanding of the HSR system explores both their understanding of the system more generally, such as its design and purpose, and how to use it correctly.

Consumer understanding is explored through the HSR Tracker and supplemented with insights from the consumer focus group.

2.2.8. Does the HSR system influence consumers to make healthier choices?

The influence of the HSR system on consumers is explored through two different but complementary approaches.

The first is through the HSR Tracker, where consumers report on the perceived influence of the HSR system on their purchasing decisions, and whether they’ve been influenced to make healthier choices.

The second approach is through sales data (see section 2.3.2). It is hypothesised that if the HSR system influences consumers to make healthier purchases, the sales-weighted average HSR will be higher than the unweighted average HSR.

The sales-weighted average HSR will be constructed for Years 3 and 4, for which sales data is available, and compared to the corresponding unweighted average HSR.

2.2.9. Has the HSR system had an impact on manufacturers’ formulation decisions?


A secondary intention of the HSR system is to encourage manufacturers to reformulate their products in order to improve the healthiness of their products and increase their star rating.

Therefore, to assess whether there has been any change in the average HSR of products, the nutrient status and star rating of products participating in the HSR in Year 4 is compared to their nutrient status and (calculated) star rating in Year 1.

To determine whether the change between Years 1 and 4 is due to participation in the HSR system, a sample (see next section) is taken of eligible, but non-participating HSR products. The star rating is calculated for these products based on their Year 4 and Year 1 data, to determine whether there has been any change.

The change over time for HSR products can then be compared to that of non-participating products to ascertain whether any change over time can be attributed to participation in the HSR system.

Sampling

The first step in establishing a sample is to understand how many products in Year 4 were also in the market in Year 1.

There were 1,802 products participating in the HSR in Year 4 that also existed in the market in Year 1, accounting for just under 40 percent of all Year 4 HSR products.

As for non-HSR products, there were 4,130 non-participating products in the market both in Year 1 and Year 4, accounting for about one-third of all Year 4 non-HSR products.

As a result of the sampling process, there was a total sample of 319 paired HSR products and 354 paired non-HSR products selected for analysis. The paired HSR and non-HSR samples was a representative sample of all HSR categories.

A two one-sampled chi-square test was conducted with results confirming that the HSR and non-HSR sample of products are representative of their respective populations in terms of HSR categories (ꭕ2(df=75) = 0.04, p = 1.00 and ꭕ2(df=81) = 0.15, p = 1.00).

However, due to the agreed sampling methodology and lack of statistical power, results cannot be reported at a category level and will therefore be reported at an aggregate level.10

2.3. Data sources

2.3.1. FoodTrack

FoodTrack™ is a food composition database established in June 2014 as a joint initiative between the Heart Foundation and the Commonwealth Scientific Industrial Research Organisation (CSIRO).

For each product collected within FoodTrack™, product information (e.g. brand, package size), nutrition information (e.g. energy and nutrients), and participation in the HSR is recorded. Eligibility of products to participate in the system is assessed and mapped to corresponding categories (e.g. HSR Category Class and HSR Category Name).

FoodTrack™ aims to include all food products sold in supermarkets with more than 17,000 products added to the database annually. Products are added to the database on a rolling schedule by category, with more

10 See Figure B.1 of Appendix B for hierarchy of categories used for the HSR system.


than 80 food and beverage categories collected over a 12-month period. Trained data collection field officers (qualifications in nutrition and/or dietetics) populate the FoodTrack™ database on an ongoing basis by collecting data in-store using smartphone technology.

With a systematic and comprehensive method for collecting food products, FoodTrack™ has greater than 90 percent coverage for each category within major supermarket retailers.11

To assist the monitoring and evaluation of the HSR, the functionality of FoodTrack™ has been expanded to capture images of the HSR graphic with additional information.

Eligibility

The HSR system has been developed for use on packaged products. Nonetheless it’s not suitable for all packaged products. Products not eligible to display the HSR system are outlined in the HSR system Style Guide which cross references the FSC and aligns with other restrictions outlined in the Code.

It was not intended that the HSR be applied to single ingredient products and those that didn’t require a NIP. However, over time an increasing number of manufacturers begun including the HSR system logo on these kind of products. Examples include seasonings and herbs, packaged plain meat/seafood and unprocessed fruit and vegetables.

Products that are either not eligible for the HSR, or not intended to display the HSR are considered outside the scope of eligible products. However, for the purpose of the analysis undertaken for this report, where products are not intended to display the HSR, but do, these are subsequently considered within the scope of eligible products.

2.3.2. Sales data

Sales data is from Nielsen, a global measurement and data analytics company. Nielsen has a shopper panel, called HomeScan®, comprises 10,000 households, which is demographically and geographically representative of the Australian population.

Each household is provided with a handheld scanner, which is used to enter the details of all products purchased – product, quantity, price and outlet. The information is then transmitted directly to Nielsen.

Households participate for a period of four weeks at a time. This is aggregated across all households to provide sales data for a 12-month period, aligning with the HSR reporting periods.

The sales data is then mapped to products from the FoodTrack™ database using a unique product identifier (i.e. stock keeping unit).

The volume of sales is used to weight each food product in the FoodTrack™ database. The purpose of weighting is to reflect that some products have more influence than others. For example, the more people consume of a given product, the more important that product is in terms of its contribution to food supply and people’s diet.

For Year 3 and 4 products, sales weighted data will be used in the calculation of:

Uptake of HSR

Average HSR rating

Nutrient status of HSR and non-HSR products.

11 Major supermarket retailers include Coles, Woolworths, Aldi (since 2016) and IGA supermarkets (since 2017)


2.4. Evaluation tools

2.4.1. Style Guide

The Style Guide is the key tool available for manufacturers and retailers to know what HSR logo they can use, and how to apply it to their product’s packaging.

Leveraging the Style Guide, a checklist has been developed as a series of yes/no questions designed to systematically and objectively assess participating products. As the requirements for compliance vary by HSR logo, a separate checklist has been developed for each logo, which includes five core questions regardless of logo used.

2.4.2. HSR calculator

Using the HSRC, the star rating for HSR products was independently calculated and compared to the HSR displayed on pack.

The star rating is only assessed for products that use a version of the HSR system graphic that involves the star rating (i.e. not for products using the energy icon).

The majority of the information required to independently calculate the HSR is drawn from FoodTrack™, which pulls information from the NIP and ingredients list. However, presentation of some nutrients (e.g. Fibre) is optional under the labelling legislation and not all FVNL content can be quantified from the ingredients list, which means there are instances where information required for the calculation of the star rating is missing.

In Years 1 and 2, products with incomplete information were excluded from further analysis because they accounted for less than 5 percent of all products (see Table 3). However, in Year 3 and 4 the proportion of the sampled products with incomplete information was greater than 50 percent.

Table 3: Proportion of products with incomplete information

Year Products with missing or incomplete information

Products eligible for assessment

Year 2 87 1,822 4.8

Year 3 308 543 56.7

Year 4 305 496 61.5

Source: FoodTrack™; Heart Foundation calculations

Consequently, excluding products with incomplete information from the sample in Years 3 and 4 would potentially bias the sample and would therefore not be statistically representative of the total HSR population. Therefore, in these circumstances, missing or incomplete information was imputed from another equivalent product for which the information is available. Depending on the information missing, different approaches are taken to its imputation. These approaches are outlined further below.

Managing missing fibre values


It is not mandatory that fibre be listed on the NIP for products, however, if there is more than 0.9g/100g fibre in the product, additional points can be attracted in the calculation of the HSR.

To determine whether it is likely (or not) that a product contains more than 0.9g/100g fibre, similar products are reviewed using the FoodTrack™ database, or the standard reference food composition database, AUSNUT 2013.

For products considered unlikely to contain more than 0.9g/100g fibre (e.g. confectionary), the missing value is assumed to be zero for the purposes of the star calculation.

For products considered likely to contain more than 0.9g/100g fibre (e.g. cereal) the data is imputed from a similar generic product from the FoodTrack™ or AUSNUT 2013 database.

Where it is not possible to impute from a similar product, such as ready meals, the fibre content is estimated by creating a recipe using the nutritional analysis software, FoodWorks Professional.

Managing missing or incomplete FVNL and/or concentrated FV values

FVNL or concentrated fruit or vegetable (FV) are estimated based on the products’ ingredients list. Products containing at least 25 percent concentrate FV content or more than 40 percent FVNL content can attract additional points in the calculation of the HSR. A different number of points are awarded depending on the percent of concentrated FV and/or percent of FVNL, making it important to specify the exact percent (correct to the whole number) of FVNL and/or concentrate FV.

Where FVNL and/or concentrated FV data is incomplete, it is sometimes possible to determine the complete values through deduction, using the data from the remaining ingredients list

Where there is a mixture of complete and incomplete FVNL and/or concentrated FV data, minimum quantifiable values are used.

If there is insufficient information to deduce an exact or minimum FVNL and/or concentrated FV share, the additional points could not be calculated and therefore the products were excluded from the analaysis.

2.4.3. HSR Tracker

A national online consumer survey12 has been conducted since September 2015, with each survey exploring:

General supermarket shopping behaviour;

Awareness of food logos;

Knowledge and understanding of the HSR system;

Purchasing behaviour;

Awareness and influence of advertising (not presented in this report); and

Attitudes and perception of the HSR system.

Since July 2017, one component of the survey is varied in each ‘wave’ of the survey, enabling the exploration of topical areas of interest. Variable questions have covered the following topics:

Influence of advertising or promotion on thought or behaviour (July 2017)

Application of the HSR system to pre-packaged foods (November 2017)

12 Appendix C: HSR Tracker Survey


Increasing trust in the HSR (March 2018)

Fresh/packaged foods (July 2018)

Results from previous surveys exploring these variables can be found on the HSR monitoring website here

The survey sample is nationally representative of approximately 2,500 households in each wave, stratified by demographics and consumer characteristics, including:

Age group (under 35 years of age, 35 to 54 years of age and those aged 55 and over),

Household income per annum (less than $50,000, between $50,000 to $99,000 and $100,000 or greater),

Gender (male or female),

Body mass index (less than 25, equal to or greater than 25 and less than 30, equal to or greater than 30),

Level of education (high school, diploma and/or tafe, or university),

Language spoken at home (English spoken only at home or language other than English spoken at home), and

Location (respondent residing in metropolitan area or in regional/rural area).

Findings from the consumer surveys have been reported to the Department of Health on the completion of each survey. To generate insights additional to those already reported, responses are aggregated for Years 2, 3 and 4 of the HSR system. As the sample size for each period increases (see Table 4), this provides greater statistical power to explore how the demographic and social characteristics of respondents influence people’s responses.

2.4.4. Additional in-store collections

Historically, uptake using the FoodTrack ™ database could only be reported on an annual basis. For the purposes of reporting uptake on more regular intervals, additional in-store collections were required. The additional in-store collection takes place over eight consecutive weeks in major retailers,13 where product information and HSR status is collected.

The additional in-store collection is then supplemented with retailer data from ALDI and Woolworths, which include private label HSR products intended to display the HSR but waiting for a print run, FoodTrack ™ data and online desktop research.

Since 2015, seven additional in-store collections have been undertaken with uptake figures reported directly to HSRAC for the following time periods:

1. September 2015

2. January 2016

3. May 2016

4. August-September 2016

5. February-March 2017

6. August-September 2017

7. February-March 2018

The additional uptake data provides a cumulative measure of the number of products that are currently displaying the HSR, have displayed the HSR since inception and those that intend to display the HSR in the near future. It does not reflect the total number of products available for sale at the given timepoint.

2.4.5. Focus group

Focus groups were undertaken in July 2018 to explore in further detail consumers perceptions, opinions and beliefs towards the HSR. Specifically, the focus group discussed:

Food claims and logos – what are they familiar with, and what impact does it have upon their behaviour;

HSR logos – what they preferred and why;

Trust in the HSR system – why do or don’t they trust the system, and what could be done to increase it; and

Understanding the HSR – what do the stars mean, and how does or doesn’t it help to select products.

Four focus groups were held in July 2018, two in South Melbourne, Victoria (metropolitan) and two in Traralgon, Victoria (regional). The different location of the focus groups providing a greater variety in the type of participants, particularly in relation to socio economic status, employment status and family structure.

13 Two large metropolitan Coles, Woolworths, Aldi (since 2016) and IGA supermarkets (since 2017) in Victoria.


There were approximately six to eight participants in each focus group.


Chapter 3: What is the uptake of the HSR system?

In this section the number of products participating in the HSR system is explored

by category,

relative to eligible products, and

weighted with sales data

to gain further insight into coverage of HSR in relation to people’s consumption.

3.1. Participation in the HSR

3.1.1. Annual HSR uptake

In the first year of the HSR system, there were 363 products participating (see Chart 1). In Year 2, more than four times as many products were participating than Year 1 (2,021). In Year 3, participation grew further, although at a slower rate (77.5 percent). In Year 4, participation grew again, but at an even slower rate (51.9 percent) with a total of 5,448 products displaying the HSR over the year.

Since the HSR system was introduced, a total of 7,312 products have participated in the HSR system. This figure includes products currently dipalying the HSR, but also captures products that no longer display the HSR or products that have been delisted. Therefore, this figure does not reflect the number of HSR products currently in the market.

3.1.2. Additonal in-store collection

Participation of products in the HSR system has also been measured using an additional in-store collection. The additional in-store collection provides a cumulative measure of the number of products participating in the HSR, while also capturing products that are anticipated to be available on shelves in the near future.

As illustrated in Chart 2, this in-store collection method shows that by March 2018, 10,333 products have participated, are participating, or are soon to be participating in the HSR system. Participation measured using the additional in-store collection is approximately 3,000 products more than the cumulative uptake measure reported through FoodTrack™. This is a combination of additional products that have been identified through the additional in-store collection which have not yet been captured in the annual FoodTrack™ collection and the inclusion of products soon to be participating in the HSR system.

Therefore, depending on purposes of reporting, either figure may be appropriate. Both data sets are equally valid and provide different measures of industry uptake. However, for most purposes and for the purpose of this report, the rolling annual collection using FoodTrack™ figures will be used for analysis. It is more definitive in reporting actual use of the HSR (i.e. doesn’t include products that are not intended to display the HSR) and is based on a longer and more thorough in-store collection process.

3.1.3. Eligibility of uptake

Missing from both measures (section 3.1.1 and 3.1.2) is a sense of context; how does the number of products participating in the HSR compare to the total number of products eligible for participation? (Eligibility = products intended to display the HSR as outlined in section 2.3.1). This is provided in Chart 3 which shows the number of products participating (measured using FoodTrack™) divided by the total number of eligible products. This shows that the proportion of products displaying the HSR system has grown from 2.9 percent in Year 1 to 30.5 percent in Year 4.

As uptake of the HSR has increased, so too has the coverage of categories. There are 83 categories14 in total, with Year 1 products drawn from just 36 categories. Fast forward to Year 4, and the HSR now includes products from all but two categories: Poultry – plain and Bakery fats.

3.1.4. Uptake by Category

Presented in Chart 4 is the uptake of the top five categories that have the greatest proportion of products participating in the HSR system in Year 4. Two out of the five categories had no products participating in Year 1 however by Year 4, they had contributed to the top five which shows that different categories had differing trends in uptake.

14 See Figure A.1 of Appendix A for hierarchy of categories used for the HSR system.


Chart 4: Proportion of products participating in the HSR system from the top five categoriesClick to view the text version of Chart 4.


Other categories that had a relatively big impact on uptake of the HSR are Confectionary and Sugar (or artificially) sweetened beverages. These categories had the largest number of products participating in the HSR system. They collectively accounted for 680 products and together accounted for over 12 percent of all products participating in the HSR system in Year 4. Except for the Confectionary category in Year 4, the proportion of products displaying the HSR for these two categories continued to increase each year (see Chart 5).

Chart 5: Categories with the largest contribution to uptakeClick to view the text version of Chart 5.



3.2. Sales weighted uptake

To understand the market penetration of the HSR, uptake is weighted by sales data. Sales weighted uptake of the HSR is compared to unweighted uptake for Years 3 and 4 in Chart 6. This shows that in Year 3 there is no difference between unweighted and sales weighted uptake, whereas in Year 4, sales weighted uptake is statistically larger than unweighted. This suggests that in Year 4, products participating in the HSR formed a relatively larger proproprtion of products purchased compared to non-HSR products.

In Year 4 at a category level, sales weighted uptake was higher for six out of ten categories. For most categories, the change has been relatively small, increasing or decreasing between 0 to 10 percentage points (see Chart 7).15 But for a handful of categories, the change has been significant, with a change greater than 10 percentage points.

To observe the change in uptake at a category level in further detail, Table 5 looks at the top five categories that had the greatest change in sales weighted uptake compared to unweighted uptake. For all five categories, there was a change of greater than 20 percentage points. This indicates that products from these categories displaying the HSR system were were more frequently purchased.

3.3. How does HSR uptake compare to other front-of-pack labelling schemes?

Other FoPL schemes have previously been introduced in Australia with a similar objective to the HSR. In 2006 the industry led Daily Intake Guide (DIG) was introduced to empower consumers to make informed choices. Results show that 78 months post implementation, the DIG appeared on over 7,200 products in all major categories.16 This compares to 7,312 products displaying the HSR 48 months post implementation.

Chart 8 plots the uptake of the DIG and HSR at the equivalent points in time post implementation and demonstrates that uptake of the HSR has been higher and faster.

In addition, uptake of the HSR system in Australia can be compared to the same HSR system in New Zealand. From implementation, uptake of the HSR system in Australia has been higher. In Year 2 uptake in New Zealand had only reached 5.5 percent of eligible products compared to 14.6 percent in Australia. By Year 4, the HSR system in Australia had nearly two times as many products as New Zealand (n=2,297) (see Chart 9).

3.4. Drivers of uptake in participation

At an aggregate level, the key driver of uptake was the participation of large retailers, who expanded the HSR across their suite of products. This can be seen at both the category level, and at the system as a whole.

The key players that have driven uptake are the private label retailers: Coles, Woolworths and Aldi. As illustrated in Chart 10 the three private label retailers account for over half of all products participating in the HSR system.


Chart 10: Coverage of Private labels Click to view the text version of Chart 10.


The growth of HSR products among private labels increased from Year 1 to Year 2 as Woolworths expanded its coverage 9-fold, and Coles 4-fold to each cover approximately one-third of their eligible products (27 percent and 36 percent respectively). This increase continued in Year 3. However, by Year 4, the overall coverage of private labels decreased by 2.59 percentage points. In Year 4, the proportion of Private Label – Coles and Woolworths products had decreased (compared to Year 3 proportions) in contrast to Private Label – Aldi which increased by 2-fold.

As the private label retailers expanded the number of their products participating in the HSR, they have also driven overall growth in the number of products participating in the HSR system. This is illustrated in Chart 11 which shows the proportion of growth in HSR products attributed to the participation of private labels.

In addition to the three private label retailers previously discussed, a further 12 manufacturers (participating in Year 3 and 4, out of a total 97 and 134 manufacturers respectively) contributed to more than 80 percent of products participating in the HSR system (see Table 7).

The pattern of uptake of the HSR may provide learnings to other countries that are interested in introducing or attempting to increase participation in voluntary FoPL scheme; participation of large retailers and manufacturers is instrumental to delivering rapid uptake of the scheme.

3.5. Concluding comments

Uptake of the HSR in Australia has been rapid when compared to uptake of one other FoPL scheme introduced in Australia, or the uptake of the HSR system in New Zealand.

Uptake of the HSR has been increasing year on year, with large retailers being the key driver of growth. However, since Year 2 the rate of growth in participation has declined.

Sales weighted uptake is larger than unweighted uptake in Year 4. This tells us that the market penetration of the HSR system is greater than understood by considering unweighted uptake alone.

Chapter 4: Do manufacturers comply with the HSRC and guidelines?

The objective of this chapter is to report on manufacturers and retailers’ compliance with the system by assessing whether the HSR is displayed correctly with outlined design specifications, and the HSR value displayed is true and accurate.

4.1. Style Guide compliance

Using the Style Guide assessment checklist, products are systematically and objectively assessed for design and technical variations. Design variations don’t change the meaning of the HSR system graphic and/or content, however they may create confusion, and the information displayed could be misleading. On the contrary, a technical variation can change the meaning of the HSR system graphic.

Presented in Chart 12 is the proportion of products that have design or technical variations based on the sampling approach undertaken (see section 2.2.2). This shows that the proportion of overall variations were at their lowest in Year 4. Chart 12 also shows that the majority of variations are design variations and the proportion of technical variations decreased each year.

Notes: a. Sample: Year 1 n=382, Year 2 n=2,109, Year 3 n=628, Year 4 n=520Source: FoodTrack™; Heart Foundation calculations

The most common design variation in Year 1 was a combination of HSR logos displayed on pack. That is, one product displayed two out of the five HSR system graphics available. In many cases it was an Option 1-4 accompanied by the energy icon being (Option 5). This variation accounted for 80.8 percent of design variations (see Chart 13). However, this type of variation declined over time, and by Year 4 the most common design variation was the placement of a second HSR logo with a varying design on the back of pack (34.1 percent). In Year 4 the second most common design variation was the rounding of nutrient values


`to the incorrect decimal place – the Style Guide requires that nutrients measured in grams be reported to one decimal place and nutrients measured in milligrams be reported as a whole number.17

As illustrated in Chart 14, the incorrect NRM is the most common technical variation. This error is specific to beverages and confectionary products which are required by system guidance to use the industry agreed standardised serve size. As the intention of the NRM is to ensure that consumers’ dietary intake is in alignment with the Australian Dietary Guidelines (ADG), use of the incorrect NRM amongst these categories can lead to excess intake of energy dense and relatively nutrient-poor foods.18

Through the identification of design and technical variations, compliance (or otherwise) with the Style Guide can be determined. While some products may be classified as having design or technical variations, it does not automatically imply that the product is non-compliant. Non-compliance is determined from specific technical variations where the HSR displayed is classified as an error and/or inconsistent with Style Guide.

As illustrated in Chart 15, in every year since implementation more than nine in every ten products have been compliant with the Style Guide. In Year 1, compliance with the HSR Style Guide was at 92.7 percent of products participating. This has increased over time and by Year 4, compliance reached 95.8 percent.

4.2. Assessment against the HSR Calculator

To assess whether manufacturers and retailers are correctly calculating their star rating, a sample of products have had their star rating independently calculated. This assessment shows that compliance is greater than 90 percent, although there has been a decline in compliance since Year 1 (see Chart 16).

Where a product doesn’t comply, it can be due to the star rating displayed on pack being higher or lower than independently calculated. With the exception of Year 4, more manufacturers and retailers are understating their HSR than overstating it (see Chart 17), and cumulatively over the four years, the same pattern has been observed.

Àcross all years, the proportion of products with a calculated HSR that differed to that displayed on pack was generally over or understated by 0.5 stars. This is illustrated in Chart 18 which presents the distribution of products that have over or understated the star rating.

Compliance with the HSR Style Guide is over 90 percent for products each year. And despite Year 4 with a slight decline, compliance with the HSRC was also at almost 90 percent.

Over the four years, misalignment between the HSR calculated and that on pack has been driven by both under and overstatement of the HSR, suggesting there is no systematic bias towards overstating a products star rating.

Chapter 5: Are consumers aware of the HSR system?

Consumer awareness can be broken into prompted and unprompted awareness, with unprompted awareness indicating a greater awareness (see section 2.2.3).

To ascertain whether demographic or social characteristics are associated with awareness (or lack thereof), additional analyses are undertaken.

5.1. Consumer awareness

Consumers were asked about their awareness of different logos that help customers choose food to buy in supermarkets (unprompted). By Year 4, 20.2 percent of consumers recalled the HSR, only 3 percentage points behind the Heart Foundation Tick, and this was a 61.8 perecent increase from Year 2 (see Chart 19).

In comparison, during the same period, unprompted awareness of Australian Made logo has increased just 5.3 percent and the Heart Foundation Tick has fallen by 35.6 percent.

Chart 19: Unprompted awareness of food logosa


Notes: a. Sample: Year 2 n=4,041, Year 3 n=7,012, Year 4 n=7,481.Source: Heart Foundation HSR Tracker

Prompted awareness of the HSR has steadily increased over time. By Year 4, four out of every five consumers were aware of the HSR. This is up from 56.8 percent in Year 2, which is an increase of 46.6 percent (see Chart 19).

5.1.1. Which consumers are more likely to be aware of the HSR system?

This section looks at whether awareness of the HSR differs signifcantly by socio demographic characteristics of the consumer.

At an individual level, females (compared to males), younger consumers (compared to those 55 years and older), those who are university educated (compared to high school or tafe/diploma), and those with a BMI in the healthy weight range (compared to overweight or obesity), are significantly more likely to be aware of the HSR, be that prompted or unprompted.22,23

At a household level, those with a higher household income (greater than $50,000 compared to less than $50,000), and households with children (compared to without children) are significantly more likely to be aware of the HSR, be that prompted or unprompted.19,20

These findings are similar to those observed in other studies of FoPL schemes, which also find that women, those on higher incomes and those who have attained a higher level of education are most likely to report awareness of labels.21

Studies have found that parents of children living at home are more interested in nutrition, which likely explains the greater awareness for persons from households with children.22



21 Cowburn, G., Stockley, L. 2005, ‘Consumer understanding and use of nutrition labelling: A systematic review’, Public Health Nutrition, vol. 8, issue 1.

22 Cowburn, G., Stockley, L. 2005, ibid.


`The fact that people with a BMI in the healthy weight range are more likely to be aware of the HSR system suggests there may be an element of ‘preaching to the converted’ with FoPL, as those who look at health labels are more likely to be health conscious. However, it is important to note that this phenomenon is not unique to the HSR23 and is a challenge common to the design of many programs or interventions attempting to engage the unengaged.24


Consumer awareness of the HSR continues to increase. The demographic profile of those most likely to be aware of the HSR are similar to those of other studies of FoPL schemes, however, it raises some concern that awareness is lower for consumers that are overweight and obese than those with normal BMI, who could potentially benefit the most from the system in terms of making healthier food choices.

Chapter 6: Attitude formation Unlike other chapters in this report which present a singular evaluation question, in this chapter all the evaluation questions related to attitude formation are presented together. Each evaluation question is addressed in turn, with concluding remarks used to bring together the findings of each of the evaluation questions to provide insight into consumers’ attitude towards the HSR system.

6.1. Do consumers trust in the HSR system?

Trust in the HSR system is a crucial element of attitude formation, as without it, consumers will be hesitant to make a purchase based on a product’s HSR status. To understand consumers’ sentiments on the HSR system, consumers were asked directly through the HSR Tracker how strongly they agree that the HSR system is one they trust and perceive as credible.

As illustrated in Chart 21, by Year 4 almost six in every ten consumers trust the system, and even more find it credible. Also illustrated in Chart 21 is the growth in trust and credibility over time; 8.0 percent per annum for trust, and 5.4 percent per annum for credibility.

Chart 21: Proportion of consumers that trust in the HSR systema

Click to view the text version Chart 21.


Findings from the focus groups convey participants generally trusted the HSR system. There was recognition that the HSR provides a quick easy reference on the healthiness (or otherwise) when buying a product. Some participants also highlighted that its placement on products they trust is the reason they trust the HSR system.

Credibility of the system is one area that received more vocal criticism in the focus group, particularly from those who take a stronger interest in nutrition. These participants had their own understanding of healthy/unhealthy, which lead them to disagree with the star rating for some products. For example, one


`participant felt that the star rating for yoghurt is too low, while the star rating for certain breakfast cereals is too high. For this participant, this undermined the credibility of the system as a whole.

Perceived confidence in the HSR system is presented in Chart 22 and shows that confidence in the HSR has increased significantly over the three years. In Year 2 the majority of consumers were not confident in the system, however; confidence had increased to just over half in Year 3, and then further again to almost 70 percent in Year 4.

This may suggest that as consumers have had greater exposure to the HSR system, their level of confidence has correspondingly grown.

Chart 22: Confidence in the HSR systema Click to view the text version of Chart 22.


6.1.1. Who trusts the system?

To understand whether demographics or household characteristics have any influence over who is more likely to trust the HSR system, for those who said they trusted the HSR system, their characteristics were explored.

At an individual level, males (compared to females), those who are university educated (compared to high school or Tafe/diploma), those with a BMI in the healthy weight range (compared to overweight or obese), are significantly more likely to trust the HSR system.

At a household level, those with children at home (compared to households without children), those that speak a language other than English (compared to English speaking households), those that live in metropolitan regions (compared to rural regions), and those with higher household income (greater than $50,000 compared to less than $50,000) are significantly more likely to trust the HSR system.25



`

6.2. Do consumers find the HSR system useful?

Consumer attitudes towards the HSR system are a reflection of the relevance and usefulness of the system to an individual or household.

The HSR system is intended to make it easier for consumers to compare products and make healthier choices. Most consumers agree that the HSR system makes identifying healthier products easier (see Chart 23), however, some consumers don’t feel the HSR adds value. Over one in four consumers reported that the HSR is just another thing on a pack that makes shopping more confusing.

6.2.1. To whom is the HSR system the most useful?

To understand whether demographics or household characteristics have any influence over who is more likely to perceive the HSR system as useful, their characteristics were explored.

HSR 'makes it easier for me to identify the healthier option within a category’

At an individual level, consumers aged 55 years and older are statistically more likely than younger consumers to report the HSR helps them to identify healthier options.

At a household level, those with children are more likely to agree the HSR assists them in identifying healthier options than households without children. Also, households with higher income (greater than $50,000 compared to less than $50,000) are significantly more likely to report the HSR assists them in identifying healthier options.26

HSR ‘helps me make decisions about which foods to buy’

At an individual level, consumers with a BMI in the healthy weight range (compared to overweight or obese) are more likely to report HSR helps them to decide about what to buy than consumers in the overweight or obese range.27



Àt a household level, those with a higher income (greater than $50,000 compared to less than $50,000) are significantly more likely to report the HSR helps them to decide about which foods to buy.

6.3. Do consumers understand how to use and interpret the HSR?

The objective of the HSR system is to make it easier for consumers to compare packaged products and make healthier choices. As illustrated in Chart 24, when unprompted, more than half of consumers understand that the HSR provides a rating to the healthiness of the product upon which it appears, increasing significantly in Year 4.

In rating the healthiness of individual products in a standardised way, the HSR system facilitates comparison of products participating in the HSR system. This is understood by consumers, with more than seven in every ten consumers agreeing (or strongly agreeing) that the HSR makes it easier to compare products (see ).This proportion of consumers was quite consistent throughout the years.

Less well understood is that participation in the HSR system is voluntary, or that it was developed by the Australian, state and territory governments in collaboration with industry, public health and consumer groups. This was a finding from the focus groups. In fact, some participants had assumed that it was licenced and that manufacturers pay to have the HSR on their products. Once participants had a greater understanding of the system, the majority thought it should be compulsory across all packaged products. It was stated that this


`would provide greater transparency as to the healthiness of all products and improve the ability to compare all products.

6.3.1. Understanding the ‘stars’

While consumers have a general understanding that the star rating is an indication of the healthiness of the product, it is necessary that consumers understand how to interpret the number of stars correctly. That is, the higher the number of stars, the healthier the product, and conversely, the lower the stars the less healthy the product.

Most consumers understand that a product with five stars is the healthiest choice, and a product with one star, the least (see Chart 26).

6.3.2. Understanding what can be compared

As outlined earlier, there is a good understanding that the HSR system can be used to compare products. However, comparison should only be made between similar products.

According to the HSR Tracker, this nuance is not well understood; more than half of consumers mistakenly agree (or strongly agree) that it can be used for comparison across different food categories (HSR Category). This is illustrated in Chart 27.

During the focus groups participants were presented with pairs of products and asked whether they could or would compare the HSR on the products. In this environment, participants exhibited an understanding that the HSR should only be compared for similar products.

6.3.3. Using the HSR system

Reflecting consumers’ understanding of the HSR system, the largest proportion of consumers said they would use the HSR system to compare products (27.2 percent) (see Chart 28). A further 19.0 percent would use it as a general or quick guide to determine the healthiness of a food product.

6.4. Which HSR logo do consumers prefer?

6.4.1. Preferred HSR logo

There are five different variations of the HSR logo that can be displayed on pack. Consumers were asked directly which logo they prefer. As illustrated in Chart 28, most consumers prefer Option 1 (63.3 percent), followed by Option 4 (21.1 percent). Chart 29: Overall preference of HSR logo, Year 4a

Notes: a. Sample: n=6,233Source: Heart Foundation HSR Tracker

For those that prefer Option 1, the main reason is because it provides the most detailed information, while those that prefer Option 4 do so because it is simple and uncomplicated.28

The conflicting preference for lots of information (Option 1) or simplicity (Option 4) reflects the complexity of consumer preferences, as found in other studies.29 Some consumers prefer the nutrient information provided by Option 1, as consumers look more closely at nutrients they are trying to avoid.30 Conversely, some consumers find the nutrient information difficult to interpret, and that it increases the cognitive load associated with the logo.31

As most consumers preferred the detailed information provided by Option 1, it could be hypothesised that consumers would also appreciate the detailed information provided by Options 2 and 3, over Option 4. This

`was put to participants of focus groups, which reported that they liked ‘to have either lots of the detailed information (Option 1) or none (Option 4). Participants felt that Option 2 and 3 were compromises that didn’t deliver on the benefits of either Option 1 or 4.

6.4.2. Consumers preferred attributes for HSR logos

To understand consumers’ preference, consumers were surveyed to ascertain which logo is easiest to understand, easiest to recognise and which logo provides the most appropriate/preferred level of information. Consumer preferences have been brought together into one chart to provide an overall picture of which logo has the best combination.

Consumers were most likely to choose Option 1 when asked which logo provides sufficient information, followed by Option 4. Consumers were also most likely to report Option 1 was the easiest to understand. However, Option 4 was most likely to be voted ‘easiest to recognise’, followed by Option 1.

As illustrated in Chart 31, there has been a notable shift in preferences towards Option 4 for its ease of recognition. There has also been a small shift in preference for Option 4, over Option 1, for ease of understanding. But overall, preference for Option 1 was, and is, higher than Option 4.

6.4.4. Which logos do manufacturers use?

Presented in Chart 32 is the proportion of products displaying the different HSR logo options. This shows that in Year 4, the most common logo on packs is Option 4, with almost four in every ten using the option.

Looking at the proportion of logos on products since Year 1 shows that there has been a significant shift over time (see Chart 33). In Year 1, Option 1 was the most common, but by Year 4 it was the least common.

Ìn Year 2 the Heart Foundation undertook consultations with industry, which included exploring the rationale for selecting logos.32 Manufacturers and retailers reported that the most important factor when deciding on a logo was the size of the package and available space. Given the prevalence of Option 4 and 5 (54.3 percent), this suggests that the significant shift away from Option 1 may be due to lack of available space on the package.

During industry consultations, simplicity was another important consideration identified. Manufacturers and retailers highlighted that ‘simple was better’, in recognition that FoP ‘real estate’ is limited, and that too much information can overwhelm consumers and dilute the message. This reflects the literature which finds simple labels promote more accurate nutrition judgements on unhealthy products.33

6.4.5. Do consumer preferences match logos on packs?

Based on the HSR Tracker and uptake data, there is limited alignment between what HSR logos consumers prefer to see on packs, and what manufacturers place on packs. As illustrated in Chart 34, this is particularly the case for Option 1, which is most preferred by consumers (63.3 percent) but is used least on packs (5.2 percent) in Year 4.

Trust in the HSR system amongst consumers and the perception the HSR is a credible system continues to increase, both reaching their peak in Year 4.

Most consumers know how the system works, that is, they can interpret the number of stars correctly. Almost three quarters of consumers also have a good understanding that the HSR system makes it easier to compare products. However, comparison should only be made between similar products. This level of detail is not well understood, with more than half of consumers agreeing that the HSR can be used for comparison across different food categories (HSR Category).

A large proportion of consumers find the HSR system useful in identifying the healthier option and also in making purchasing decisions.

Overall, consumers prefer Option 1, which provides the star rating and additional nutrient information. However, this is the least common logo placed on products by manufacturers.


`

Chapter 7: Does the HSR system influence consumers to make healthier choices?

The HSR has the objective of assisting consumers to make healthier choices. In this section we explore the influence of the HSR on consumers when making purchases, and whether this is leading to consumers making healthier choices.

7.1. Does the HSR influence consumer choices?

In Year 4, the majority of consumers (69.5 percent) reported purchasing a HSR product in the last three months. The proportion of consumers who recalled purchasing a HSR product has increased by greater than 40 percent compared to Year 2 (Chart 36).

Chart 36: Purchase of HSR products over the past 3 monthsa



Of these consumers, almost two thirds (64.4 percent) stated that the HSR status of the product influenced their decision (Chart 37). With increasing awareness of the HSR system, consumers were more likely to state the HSR influenced their decision when purchasing food products, significantly higher in Year 3 and Year 4 compared to Year 2 (Chart 36).

Notes: a. Sample: Year 2 n=1,115, Year 3 n=3,358, Year 4 n=4,330Source: Heart Foundation HSR Tracker

Just over half of consumers in Year 4 who had either not purchased a HSR product or had but weren’t influenced by the HSR status of the product stated that the HSR status is likely to influence their choice when purchasing food in the future (see Chart 38).

However, as illustrated in Chart 38, the proportion of consumers stating they are likely (or very likely) to be influenced in the future has decreased significantly overtime.


`This decrease is strongly negatively correlated with an increase in the proportion of consumers having made a recent purchase of a HSR product (r=-0.98, p<0.05). This suggests that consumers who have previously indicated they are likely (or very likely) to purchase a HSR product in the future have followed through on their intention to act, thereby reducing the remaining people likely to make a future purchase.

7.1.1. Who does the HSR influence?

At an individual level, males (compared to females), Aboriginal and Torres Strait Islander peoples (compared to non-Indigenous population), those who are university educated (compared to high school or Tafe/diploma), those with a BMI in the healthy weight range (compared to overweight or obese), are significantly more likely to report the HSR system influenced their purchasing decisions.

At the household level, those that live in metropolitan regions (compared to rural regions), those that speak a language other than English (compared to English speaking households), and those with higher annual household income (greater than $50,000 compared to less than $50,000) are significantly more likely to report the HSR system influenced their purchasing decisions.34

The influence of the HSR by demographic and household characteristics largely reflects the purchasing pattern which can be found from the latest survey results here. The one clear exception to this is younger people. While younger people (under 35 years of age) are more likely to purchase a HSR product than older people (35 years and over), they are not more likely to report the HSR system influenced their purchasing decisions.

7.2. How does the HSR influence?

Reflecting upon how consumers are influenced by the HSR, just over 50 percent of consumers who purchased a HSR products stated that it influenced them to purchase a product with a higher HSR that they have never tried, or don’t usually purchase (see Chart 39). The remaining stated that the HSR status confirmed their usual purchase.

7.2.1. Sales weighting of HSR purachases

To investigate whether this means consumers are making healthier purchases in practice, the sales weighted average HSR is compared to the unweighted average HSR. If the HSR is a factor contributing to consumers purchasing healthier products (i.e. a product with a higher HSR), it is anticipated that the sales-weighted average HSR will be higher than the unweighted average HSR.

Presented in Chart 40 is the sales weighted average HSR and unweighted average HSR for products participating in Year 3 and 4. This shows that there is minimal difference in the sales weighted HSR compared to the unweighted HSR for either Year 3 or Year 4


`

Chart 40: Sales weighted average HSR versus unweighted average HSR,a Year 3 and Year 4b


Notes: a. Only products for which sales data is available and sufficiently robust are included in the calculation. Where the RSE of a product is greater than 25 percent they are excluded from the calculation; b. Sample: Year 3 n=2,371, Year 4 n=3,372.Source: FoodTrack™; Heart Foundation calculations; Nielsen HomeScan®

These findings conclude that more than half of consumers who purchased a HSR product stated that they were influenced by the HSR to choose healthier products, however this is not yet reflected in the purchasing behaviour of all consumers that are purchasing HSR products.

7.2.2. Change in purchasing behaviours for healthier products

To investigate the overall proportion of consumers who purchased a product with more stars, analysis was conducted on those who purchased a HSR product (69.5% of consumers, Chart 36), regardless of whether the HSR influenced the purchase or not.

It is important to note that findings in this section differ to the result in Chart 39 as it solely focuses on consumers purchasing behaviours irrespective of influence as opposed to how the HSR has influenced consumers.

As illustrated in Chart 41, consistently over the three years, there was a greater proportion of consumers (two third of consumers who purchased a HSR product in the last three months) who reported that the HSR had made no change to their purchases, that is, they were uninfluenced by the HSR or the HSR confirmed their usual purchase.

The remaining proportion of consumers who purchased a HSR product had changed their purchasing behaviour. From Year 3, one in three consumers were influenced by the HSR system and purchased a HSR product with a higher star rating.

Therefore, when looking at it at an overall population level, 23.4 percent of consumers had made changes to their purchasing behaviours by purchasing a HSR product with more stars, see Chart 42.

`


Of those consumers who had purchased a HSR product, one third were influenced by the HSR to change their purchasing behaviour. That is 23.4 percent of all consumers had changed their purchasing behaviour by purchasing a product with more stars.


`

Chapter 8: Has the HSR system had an impact on reformulation?

The objective of this chapter is to analyse the nutrients and star rating of HSR products from Year 1 to Year 4 and determine whether they have changed over time. Furthermore, if there has been a change, analysis was conducted to assess whether it can be attributed to participation in the HSR system.

To this end, a sample of products not participating in the HSR system is analysed and the change over time is compared to HSR products.

8.1. Has the star rating changed over time?

In Year 1, the most common star rating was 4.0 (32.3 percent), and the average HSR was 3.8 (see Chart 43). Since then, a wider range of products have joined the HSR, which has led to more products with a lower star rating, and a corresponding decrease in the average HSR.

In Year 4, a star rating of 4.0 was still the most common, but it accounted for 22.4 percent – almost 10 percentage points lower than in Year 1. The increase in more products with a lower star rating saw the average HSR fall to 3.4 in Year 4.

`To assess the change in proportion of products displaying a HSR, it was identified that 77.7 percent of products in Year 1 displayed a HSR with ratings of 3.0 to 5.0 stars however, by Year 4, this had decreased to 63.1 percent. Therefore, this confirms that the superficial appearance of HSR products becoming less healthy over time is likely driven by new products with lower HSRs joining the system.

8.2. Have the nutrients in HSR products changed over time?

As the average HSR decreased over time, further analysis was conducted to consider whether the nutrient content in HSR products have changed, therefore attention was focused on the negative nutrients (energy, saturated fat, total sugars and sodium). These nutrients are considered in the calculation of the star rating, and are the key nutrients that consumers look for on front of pack.35

Therefore, the average nutrient content of Year 1 and Year 4 HSR products were compared. As illustrated in Chart 44, average saturated fat, sodium and sugar (per 100g or 100mL) in HSR products are higher in Year 4 than Year 1. Superficially at least, it appears that the HSR products have become less healthy over the last four years. However, it is likely that new products with a lower HSR joining the HSR system are the driver of change as opposed to existing products adding saturated fat, sodium and sugar.

Therefore, to determine whether HSR products have reformulated over time, the nutrient content of Year 4 HSR products was compared to their Year 1 nutrient content. Results from the analysis36 show that the average content is statistically lower in Year 4 than Year 1 for energy, saturated fat and sodium, with the greatest reduction over time in sodium (5 percent).37 That is, HSR products have become healthier, on average, over the last four years.

To ascertain whether the decrease in nutrients is unique to HSR products, or reflects a general trend of reformulation, average nutrient content for non-HSR products has also been analysed. These results show


37 Paired products are analysed using a paired t-test, which compares the average of the difference between each paired product.


`that there was no statistical change in the nutrient content between Year 1 and 4 for products not participating in the HSR system at Year 4.38

Given that energy, saturated fat and sodium have decreased over time for HSR products, and there has been no change for non-HSR products, it appears these nutrients have decreased for HSR products relative to non-HSR products.

To confirm this observation and conclude with statistical confidence that reformulation is attributable to participation in the HSR, the difference over time in HSR products is compared to the difference over time in non-HSR products39 (see Chart 45).

Source: FoodTrack™, Heart Foundation calculations

The results from this analysis show that the difference is only statistical for energy and saturated fat.40 This means that while HSR products have reformulated to reduce energy, saturated fat and sodium, only reformulation of energy and saturated fat in HSR products may be attributed to participation in the HSR system.

8.3. Does a change in nutrients translate to a change in star rating?

To ascertain whether the reformulation of these nutrients translates to a change in the average star rating, the HSR of a sample of Year 4 products is compared to their HSR in Year 1.41 It is important to note that the average HSR in section 8.1 is obtained from products participiating in the system and displaying a HSR. Whereas, in this section, the average HSR refers to the calculated (hypothetical) HSR for products that have been sampled for analysis. Chart 46 presents both the average and median for Years 1 and 4 for products participating in the HSR system. This chart illustrates that both the average and the median star rating are higher in Year 4 than Year 1.


41 Most Year 1 products had their HSR calculated, as there were only 363 products participating in Year 1.

Analyses were undertaken to assess whether the difference between the average and median star rating of Year 1 and 4 products was statistical. Results from analyses revealed that both the average and median star rating is statistically larger in Year 4 than Year 1.42,43 To understand whether this is due to participation in the HSR system encouraging reformulation, a paired sample of products not participating in the HSR was taken. Star ratings were calculated for Year 1 and Year 4 based on the products’ nutrition information.

The average and median calculated star ratings are presented in Chart 47 for the non-HSR products in Years 1 and 4. This shows that the average star rating has not changed, while the median appears to have decreased. Analyses on the average and the median confirm that there is no statistical difference between Years 1 and 4 for products not participating in the HSR system.44


43 A t-test is used to compare the means, while the Wilcoxin signed rank test is used to compare medians.

In summary, we observe that the star rating has increased over time for products that are participating in the HSR system, but not for products that are not participating in the HSR system. The difference is significant, which indicates participation in the HSR system may be driving healthier reformulation of products that have adopted the system45.


In this section, we have analysed the nutrients and star rating for products participating in the HSR and compared them to products not participating.

Though results revealed that the average star rating of products decreased throughout the years, this is likely driven by new products with lower HSRs joining the system.

Furthermore, results from the analysis also indicated that participation in the HSR system is leading to voluntary reformulation of products, which is in turn increasing the healthiness of products that have adopted the system.

These findings are similar to those reported on the HSR in New Zealand, which have also shown that the HSR system is driving healthier reformulation of some products.46


46 Ni Mhurchu, C., Eyles, H., Choi, Y-H. 2017, ‘Effects of voluntary front-of-pack nutrition labelling system on packaged food reformulation: the Health Star Rating system in New Zealand’, Nutrients, vol. 9, issue 8.


`

Chapter 9: Concluding remarks Across almost every evaluation question, the HSR system has shown to have a positive impact. Uptake and participation in the HSR has been increasing year on year with sales weighted data indicating that products participating in the HSR system formed a relatively larger proportion of products purchased compared to non-HSR products.

Participating manufacturers and retailer’s have largely complied with system guidance which enabled the HSR system to be displayed correctly and accurately on packaged foods. In addition, some manufacturers and retailers may also be reformulating their products to make them healthier.

From a consumer perspective, there is strong awareness of the HSR, they trust the system and understand how to use it. Given that HSR products formed a relatively larger proportion of products purchased compared to non-HSR products, the HSR is helping some consumers make healthier choices and therefore leading to a change in purchasing behaviour.

Appendix E: Text-based Alternatives for Figures

Figure 2: Conceptual Framework

It shows that awareness is the first and necessary component for nutrition information to have an impact on consumer’s purchasing decisions. It is followed by attitude formation which has four main elements: trust, usefulness, understanding of the HSR system and to which logo consumers most preferred. Having met all of these, it will lead to the decision making of whether the product's participation in the HSR system has influenced the consumer to purchase it or not.

Return to Figure 2 source.

Figure 3: Evaluation Framework

The diagram presents the different questions for each element of the evaluation framework. The questions for Monitoring Implementation are “What is the uptake of the HSR system?” and “Do manufacturers comply with the HSRC and guidelines?” For Evaluating Outcomes, there are separate questions for each factors that affects the consumer outcomes. For Awareness, the question is “Are consumers aware of the system?”. For Attitude Formation, there are 4 questions: “Do consumers trust in the HSR system?”, “Do consumers find the HSR system useful?”, “Do consumers understand how to use and interpret the HSR?”, and “Which HSR logos do consumers prefer?”. And to evaluate the impact on decision making, the question is “Does the HSR influence consumers to make healthier choices?”. To evaluate the system outcomes, the question is “Has the HSR system had an impact on reformulation?”
