Introduction

Iowans Fit for Life is a state-wide initiative which aims for all Iowans to enjoy balanced

nutrition, lead physically active lives, and live in healthy communities. More specifically,

Iowans Fit for Life seeks to set priorities for sound policy, programs, resources and messages,

and to equip communities and organizations to support an environment that encourages healthy

choices about eating and physical activity.

The purpose of this literature review is to inform physicians about the latest research on

four points related to overweight and obesity prevention. These points include childhood obesity

prevention recommendations from the American Academy of Pediatrics; motivational

interviewing in the healthcare setting, implementation of behavior change health contracts, and

physician attitudes towards obesity prevention.

Defining Obesity

Adult obesity has been widespread and growing throughout America and other

Westernized countries for quite some time (Flegal, 2007). There have been hundreds of research

studies on obesity. But before any real attempt to integrate them into a comprehensive study can

be made, definitions must be established. This process of finding a universal definition for

obesity has led to many differences in the field of obesity research. A study done by Mei (2002)

focused on comparing multiple body-composition screening indexes for the assessment of body

fatness in children and adolescents aged 2 to 19. Age-and-sex specific body mass index (BMI)

was compared with the Rohrer index (RI) and also with weight-for-height screening in this group

of subjects. Using nationally representative data from surveys of over 10,000 standardized


3/11


measurements for people between the ages of 2 to 19, it was found that the BMI was a better

predictor of overweight than the RI (Mei, 2002).

Mei (2002) showed that the BMI was indeed an appropriate predictor for overweight and

obesity. However, this study did not solve the problem of defining obesity within the scope of

BMI. Further research still needed to be done in regards to the understanding how and when to

use the BMI and how to differentiate between using the BMI and BMI percentiles for children

and adults. Krebs (2007) found that there was an absence of established criteria when it came to

cutoff points for children based on distributing anthropometric measurements. In this review of

research studies, Krebs outlined the differences between childhood obesity and adult obesity in

regards to BMI. Children were measured by BMI percentiles, whereas adults were measured by

the BMI alone (Krebs, 2007). This has been upheld by the Centers for Disease Control and

Prevention. Adult overweight is defined as a BMI between 25 and 29.9 and adult obesity is

defined as having a BMI greater than 30. Childhood overweight is defined as a BMI at or above

the 85th

percentile and lower than the 95th

percentile. Childhood obesity is defined as having a

BMI of greater than or equal to the 95th

percentile for children of the same age and sex. Rather

than using a specific BMI to determine obesity among children, their weight status is based on

age and sex specific scales. This is because a childs body composition fluctuates with age and

sex more than an adults body (Centers for Disease Control and Prevention, 2009).

Childhood Obesity Prevention Recommendations

There are three forms of prevention: primary, secondary, and tertiary. Primary

prevention is tailored towards reducing the occurrence of the disease before it results. Secondary

prevention is geared towards reducing the progress of a disease once it begins. Tertiary


4/11


prevention is related to reducing the limitations of disability from the disease (Friis & Sellers,

2009).

It should be noted that overweight and obesity lead to many other symptoms, such as:

sleep problems, respiratory problems, gastrointestinal problems, endocrine disorders, menstrual

irregularities, orthopedic problems, mental health problems, genitourinary problems, and skin

conditions (Krebs, 2007). For this reason, a variety of current research on obesity is dedicated

towards primary prevention of obesity.

The major goals outlined in The White House Task Force on Childhood Obesity Report

to the President (2010) focus on prevention: reducing childhood obesity in early childhood by

focusing on prenatal care, breastfeeding, reducing chemical exposures, reducing screen time, and

instilling the importance of education; empowering parents and guardians with the ability to

make nutrition information more readable and available, and marketing healthy food in a more

efficient manner; getting healthier food into schools; having access to healthy, affordable food;

and increasing physical activity. The American Academy of Pediatrics (AAP) also recommends

the calculation and plotting of BMI once a year in all children and adolescents (Committee on

Nutrition, 2003). Furthermore, the AAP also recommends the use of its 5-2-1-0 plan: 5 fruits

and vegetables every day, 2 hours or less per day of screen time, 1 hour of physical activity each

day, and 0 servings of sugar-sweetened drinks.

As physicians, research indicates that education may be the best form of overweight and

obesity prevention among children and adults (Krebs, 2007). However, it is important to

understand the difficulty of treating obesity. Children of obese parents have double the risk of

becoming obese and have many of the same preferences in diet and lifestyles (Zlot, 2007). This

not only predisposes children to obesity genetically, but it makes it increasingly difficult as the


5/11


environment they live in is rich with the temptations of an obese lifestyle. There are 170,000 fast

food restaurants and three million soft drink vending machines in the United States (Chopra,

2002). Todays children will be tomorrows adults. This objective reality poses a very real

threat to our nations health.

In a review done by Iowans Fit for Life regarding obesity in Iowa, it was shown that the

trends in overweight and obesity in Iowa mirror the trends of the nation. The suggestions at the

end of the study were directed at specific populations. To adults that were overweight and obese,

the plan was to aim for a slow, steady weight loss by increasing physical activity (to at least 60

minutes of moderate intensity exercise most days of the week) and decreasing caloric intake,

while making sure to establish a healthy diet. For children, it was recommended that they should

consult a health care provider before beginning a weight-reduction diet. The forms of primary

prevention that were recommended were to: create and enhance access to places for physical

activity, enhance physical education in schools and child care settings, and support urban design

and transportation policies that would result in better neighborhoods for families to exercise

(Iowans Fit for Life, 2010).

Krebs (2007) concludes, Nevertheless, the access to children and their health

information, the authority and respect that physicians and other clinicians earn from families, and

the potential to apply their knowledge to the very real medical aspects of obesity and its

associated conditions, make an imperative that all clinicians be familiar with at least a

rudimentary assessment of overweight or obese child.

Motivational Interviewing


6/11


Motivational interviewing is a newly designed tool which aims to help physicians

enhance their relationship with their patients. It is a client-centered, directive method that seeks

to instill intrinsic motivation by resolving any semblances of ambivalence (Wagner, 2010).

Research on the efficacy of motivational interviewing has shown clinical significance. One

study showed that a 51% improvement rate was shown after undergoing motivational

interviewing in regards to treating problem behaviors, such as: alcohol, drugs, diet, and exercise

(Burke, 2003).

The major tenet of motivational interviewing is what Carl Rogers described in 1951 in his

studies with psychotherapy as the principle of empathy. Rogers showed that ambivalence from

the patient is not something that should be seen as an irregularity or a pathology, but rather as a

normal human process (Burke, 2003). Motivational interviewing has adopted this belief and

seeks to be client-oriented in its approach to interviewing. In the medical field, the focus is on

the patient. Using motivational interviewing, the physician allows the patient to talk. The

physician is tasked with steering the conversation into a realistic and positive area so that the

patient feels empowered to make changes on his or her own. This can prove to be helpful in

targeting childhood and adult obesity. The goal of motivational interviewing in the area of

obesity is to get the patient to open up to the physician and to come an agreement with the

physician regarding an intervention that seems the most realistic and optimistic to them.

Behavior Change Health Contracts

Patient non-compliance has been an area of concern regarding the patient-physician

relationship, and has been around for a long time. Some of the determining factors in patient


7/11


compliance are: demographic factors, condition or disease, psychological factors, health belief

model, physician-patient relationship, treatment regimen, and setting (Griffith, 1990).

An innovative approach to dealing with the problem of non-compliance, especially in the

realm of obesity prevention, has been to establish health contracts between the patient and

physician. In association with motivational interviewing, health contracts are sought to solidify a

behavior change. Using a behavior change theory, such as the Transtheoretical Model (TTM),

can help physicians with creating lasting behavior changes. The health contract actually fits into

one of the steps of the TTM. This behavior change theory has six steps: 1. Pre-contemplation, 2.

Contemplation, 3. Preparation (this is where the health contract canoe used), 4. Action, 5.

Maintenance, and 6. Termination (Velicer, 1998).

Physician attitudes towards obesity prevention

In a survey of 620 physicians, it was found that most primary care physicians found

physical inactivity as the biggest reason for obesity. More than half of the primary care

physicians also found their obese patients as awkward, unattractive, ugly, and noncompliant.

Fifty-four percent of these physicians said they would spend more of their time on weight-

management if they were reimbursed for it in an appropriate manner (Foster, 2003).

Foster (2003) concluded that most primary care physicians share the same negative

stereotypes of obese people as the rest of the nationthat obesity is largely a behavioral

problem; and spending time treating obesity is harder than most other chronic conditions. This

same view was adopted internationallyin Australia, most general practitioners did not choose

the treatment plan which required them to support their patient in achieving and maintaining a
