Introduction Life expectancy is one of the main indicators for health inequalities. It has been set as the overarching work stream for tackling health inequalities in Birmingham by the Health and Wellbeing Partnership (BHWP).

This Ward Profile series aims to:

• Provide a detailed ward level picture of local health inequality context

• Describe life expectancy trend in each target ward

• Investigate into leading conditions that cause deaths locally to provide local focus for each target ward and

• Suggest future area/ factors for extended research

Figure 1.1 Population by age group and gender, Longbridge 2006

Figure 1.1 illustrates:

• Children under school leaving age (i.e. age 0 - 19) represent 26.91% (6,769) of the Longbridge population. Persons of retirement age (age 65+) account for 13.94% (3,506).

• The age structure of the ward indicates that it has 4.86 percentage points more people under 19 than Birmingham and 3.30 percentage points more over 65s.


1.1 Ethnicity Ethnicity has some influences in terms what kind of illness an individual could develop through their life. Thus, ethnicity analysis becomes a requirement in order to target health vulnerable people. Table 1.1 shows the ethnicity distribution in the Longbridge population, compared with Birmingham and England.

• The % column of table 1.1 represents the percentage of the total population that fit into that ethnic group. The N* column show the quantity of people in thousands that are from each group, for the ward, City and nationally.

• Under a tenth (6.8%) of the population are non-white ethnicity (i.e. Black and Minority Ethnicity (BME) Group. Within the BME group, Pakistanis represents 0.40%, Indian 0.60% and Black Caribbean 1.9%.

• The BME (6.8%) is lower than Birmingham (32.7%), and England (11.3%).

• White ethnicity (93.2%0 is higher than local and national levels.

1.4 Lifestyle

Table 1.3 provides a summary of life style indicators in Longbridge, in comparison with Birmingham and England. Data presented here are from the synthetic estimates of healthy life style behaviours from the NHS Information Centre.

• Compared with Birmingham average, Longbridge has a higher percentage of people who binge drink (0.9 percentage points higher). Less are obese (0.1 percentage points) but a higher proportion who smoke (8.9 percentage points higher)

• Compared with the national average, a smaller percentage of people living in Longbridge eat healthily (9.8 percentage point lower).

• Table 1.3 shows that smoking amongst adults in Longbridge needs to be investigated; additionally strategies are needed to get the ward to eat healthier.

2 Life expectancy trend Life expectancy is one of the most important determinants for health inequalities across the population; and there is evidence. This section gives an overview of life expectancy at birth in terms of trend and variations in different groups and communities.

Figure 2.1 shows trend of male expectancy in Longbridge from 1995/97 to 2005/07 on a 3-year basis, in comparison with Birmingham and England. Figure 2.1 shows evidence that male life expectancy has increased in Longbridge over the ten years since 1995. It is still however lower than national levels; so requires further investigation.

Figure 2.2 shows trend of female expectancy in Longbridge from 1995/97 to 2005/07 on a 3-year basis, in comparison with Birmingham and England. Figure 2.2 shows that by 2007 female life expectancy in Longbridge is actually decreasing despite being higher than 1995. More strategies are needed to identify underlying causes of this issue.

Figure 2.2 Female life expectancy for Longbridge, Birmingham and England, 1995/97 – 2005/07

As illustrated in Figure 2.1 and Figure 2.2, life expectancy for males has increased, whilst for females it has decreased. Life expectancy in Longbridge is lower than City and national average. The gap for both male/female life expectancy between Longbridge and England has increased, with the gap for women being slightly more. In conclusion:

• Male life expectancy has increased by 3.2% (2.38 years, from 73.7 years in 1997 to 76.1 years by 2007).

• The gap of male life expectancy between Longbridge and England has widened by 0.7 year from 0.9 years to 1.6 years, which means an increase of 77.8%.

• Female life expectancy has decreased by 1.3% (1.0 years, from 81.1 years in 1997 to 80.1 years by 2007).

• The gap of female life expectancy between Longbridge and England has widened by 2.1 years from 0.4 years more than England to 1.7 years below


2.1 Infant mortality In areas with high infant mortality rates, the life expectancy at birth is highly sensitive to the rate of death in the first few years of life. Infant Mortality Rate (IMR) is calculated as the number of newborns dying under one year of age in every 1,000 live births during the year, excluding still births. Figure 2.3 shows trends of IMR in Longbridge, Birmingham, England and the most deprived quintile (i.e. 20%) Super Output Areas (SOAs) in Birmingham (based on Lower Super Output Area level IMD score 2007), from 1999 to 2007.

Figure 2.3 Infant mortality rates per 1,000 births in Longbridge, Birmingham, England and the most deprived quintile in Birmingham, 1999-2007

As illustrated in Figure 2.3, in 05/07, the IMR is less than that of England; whilst that in the most deprived quintile is about two folds of England.

• From 99/01 to 05/07, the IMR has dropped by 12.2%. Along with that of Birmingham’s IMR which has also decreased.

• The gap between the most deprived quintile SOAs in Birmingham and Longbridge has dropped from 7.2 below to 5.2 below mostly because of improvements for the most deprived quintile IMR

• During the same period, the IMR in England has decreased smoothly from 5.6 to 4.9 (at about 0.1 per year). The gap between Longbridge and England has dropped from 1.5 to 0.3 (80%).


3 Local focus This section investigates into the leading causes of deaths locally.

3.1 Mortality rates on selected diseases Age-specific mortality rate is used to calculate life expectancy at birth. Disease specific standardised mortality rates are investigated into in this part in order to identify leading diseases that contribute to the overall mortality rates in Longbridge.

Table 3.1 shows directly standardized mortality rates for selected conditions in 2005-2007. Percentage of each disease’s rate out of the overall rate is also shown here. According to the figures, cancers, circulatory diseases, coronary heart disease are the major killers. They make more than 76.2% of the overall DSR. This percentage is consistent with both city and local PCT level which vary from 72% to 82%
