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.

Inclusion criteria:
- 8-10 years (block recruited to ensure 50% female, 50% obese)
- Rural geographic location (≥ 10 miles from a city of ≥ 40,000)
- Understand English
Exclusion criteria
- BMI < 5th percentile
- Major medical condition, current full-threshold psychiatric diagnosis, or moderate
suicide risk (e.g., plan or intent)
- Current or recent use (< 3 months) of medication known to affect body weight or energy
intake
- Recent brain injuries that would be expected to affect neuropsychological functioning
- Mobility impairments that would impede their ability to walk on a treadmill
- Estimated full-scale intelligence quotient score ≤ 70
- History of pregnancy
- Significant food allergies that would prevent them from safely consuming the study's
breakfast and lunch meals
- Responses on a food preference questionnaire that suggest that they do not like (i.e.,
rated them below 6 on a scale from 1 to 10) at least 50% of the food items offered in
the lunch test meal
