An Exercise Intervention to Improve the Eating Patterns of Preadolescent Children

Children in rural communities experience significant obesity-related health disparities; they are 26%-55% more likely to be obese and less likely to have health insurance and access to weight management specialists than are their urban peers. Geographic-specific disparities in obesity may be due, in part, to variations in eating behaviors. Children in rural communities describe purchasing and consuming significantly more energy-dense, low-nutrient food items relative to their urban peers. Existing behavioral strategies for improving children's EI patterns have largely been ineffective in reducing risk for excess weight gain. The primary aim of the proposed study is to test the effects of a brief, novel strategy for improving rural children's eating behaviors. Specifically, the study aims to harness the well-documented benefits of an acute bout (20 min) of moderate physical exercise on children's executive functioning, and to see if these cognitive changes lead to better self-regulation of eating. If 20 min of moderate physical exercise is associated with observed improvements in preadolescent children's eating secondary to increases in executive functioning, these data may offer explicit targets for an obesity prevention trial in rural Oregon elementary schools.
