Tackling the Childhood Obesity Epidemic through School Reforms

Tackling the Childhood Obesity Epidemic through School Reforms

A current health crisis facing developed nations is the obesity epidemic. In the United States, the prevalence of obese adults has doubled over the past fifty years (reviewed by Hurt, Kulisek, Buchanan, and McClave, 2010). Today, close to a third of Americans are obese and another third are overweight. The increase in childhood obesity is also a major concern, with the prevalence rising from 6% to 19% between 1985 and 2010. Current estimates suggest that close to a third of U.S. children are obese or overweight (reviewed by Salvy, de la Haye, Bowker, and Hermans, 2012). With an estimated yearly healthcare cost of $150 billion, obesity has become a major public health issue and is expected to soon overtake tobacco as the number one cause of preventable disease and death in the U.S. (Hurt, Kulisek, Buchanan, and McClave, 2010).

Being obese or overweight are not diseases per se, but these conditions have been shown to contribute to a number of serious medical problems including type 2 diabetes, high blood pressure, liver disease, and coronary artery disease (reviewed by Hurt, Kulisek, Buchanan, and McClave, 2010). In addition, the increased prevalence of childhood obesity has resulted in the diagnosis of diseases in children that were previously considered adult-only, including type 2 diabetes and heart disease. Being obese and overweight therefore contributes to a number of comorbid conditions, in addition to the social stigma and related psychological problems common to this demographic.

To provide a glimpse of public health efforts to reduce the prevalence of childhood obesity in the United States, the following essay will review several recent studies examining obesity trends and interventions in urban schools.

The School Obesity Environment

Efforts to reduce the incidence of childhood obesity naturally focus on the role schools can play (reviewed by Story, Nanney, and Schwartz, 2009). Next to the home environment, which public health officials have little control over, schools represent the best route for influencing the lifestyle habits of children and adolescents.
Of primary concern are the foods made available to students and the opportunities for physical activity in U.S. schools.

The availability of sweetened beverages and energy-dense snacks are widely considered a significant factors contributing to the childhood obesity epidemic. Accordingly, the number of schools prohibiting vending machines, which tend to offer these foods, was increased from 4% to 30% between 2000 and 2006 (reviewed by Story, Nanney, and Schwartz, 2009, p. 2-3). Similar trends were reported for school canteens and school stores. Despite these promising trends, such findings highlight how pervasive these foods are in the school environment. Attitudes also seem to be a problem, with 37% and 50-60% of elementary and middle/high schools, respectively, holding fundraisers offering similar types of foods and beverages. The practice of teachers rewarding classroom performance with sugary snacks is equally troubling. The reason such practices represent a threat to student health is because one study found that the body mass index of children increased by 0.1 unit for each permissive food practice allowed in schools.

Energy-dense, low nutrition foods are considered competitive foods, since they compete with more nutritious choices offered by schools (reviewed by Story, Nanney, and Schwartz, 2009, p. 3-4). A number of empirical studies have shown that when such foods are available, children and adolescents tend to reduce their consumption of healthy, nutritious foods. One study compared the eating habits of a class that transitioned from elementary to middle school and found that the sudden access to competitive foods resulted in less consumption of fruits, nonstarchy vegetables, and milk, and more consumption of sweetened beverages and high-fat vegetables. Competitive foods had not been available to these children in elementary school.

Another factor contributing to the consumption of competitive foods is the inadequate caloric and nutritional value of school meals (reviewed by Story, Nanney, and Schwartz, 2009, p. 5). The United States Department of Agriculture (USDA) has established nutritional guidelines for school lunches, which many schools must meet….....
