Brief Summary

The long-term goal is to develop effective, evidence-based lifestyle interventions to prevent and treat childhood obesity and related co-morbidities. The short-term goal, and the purpose of this application, is to quantify appetite and neural mechanisms of food reward in overweight/obese (OW/OB) sedentary youth and to quantify changes following the implementation of a physical activity intervention. The central hypothesis is that appetite becomes dysregulated at low levels of physical activity via neural reward pathways, and appetite control will improve following a long-term exercise intervention. The investigators consider this project a pilot study designed to generate data to be used for future external funding opportunities, demonstrate collaboration between researchers, and test the feasibility of the protocols.

Outcome Measures

Primary Outcomes (1)

  • Assess the effectiveness of a physical activity intervention on eating behavior- subjective responses

    To assess the effectiveness of a physical activity intervention on eating behavior in adolescents; OW/OB inactive adolescents will be randomly assigned to a 3-month exercise intervention (Exercise +Newsletter), or a control condition (Newsletter). Those exposed to the exercise intervention will have greater improvements (compared to control group) in appetite (subjective self-reported hunger responses).

    12 monthts

Secondary Outcomes (4)

  • Assess changes in structural and functional MRI in response to an exercise intervention- prefrontal and hippocampal volume

    12 months

  • Assess changes in structural and functional MRI in response to an exercise intervention- reward and control

    12 months

  • Assess the effectiveness of a physical activity intervention on eating behavior- subjective responses

  • Assess the effectiveness of a physical activity intervention on eating behavior- biological responses

Study Arms (6)

Orientation

NO INTERVENTION

Informed consent, height, weight, and blood pressure measurement. A link to an online survey the participant and their parent can fill out at home about the participant's medical history will be given.

Measurement session Pre/Post Intervention

NO INTERVENTION

Questionnaires completed, blood draws, and fixed and ad lib meals completed to measure appetite and hormones. DXA completed.

Home Assessments Pre/Post intervention

NO INTERVENTION

24-hour dietary recalls. Physical activity measured by monitors (Actigraph, ActivPAL).

Physical Activity Session Pre/Post intervention

NO INTERVENTION

DXA, and Fitness testing to measure VO2submax and VO2max. Cognitive assessments will be administered.

fMRI Session Pre/Post intervention

NO INTERVENTION

The participant will have an fMRI completed and answer questions related to 60 food and activity images while in and out of the fMRI machine.

Exercise Intervention/Newsletter

EXPERIMENTAL

After completion of the initial fMRI session the participant will be randomly assigned to intervention for 3 months and then complete another round of assessments described as above (except for the orientation session).

Behavioral: Exercise InterventionBehavioral: Newsletter

Interventions

Youth randomized to the active condition will participate in an organized exercise program. During the exercise program, adolescents will participate in a supervised structured exercise (treadmill walking/cycling on stationary bike) on 3 days equivalent to approximately 180 min/week of moderate-intensity exercise. The rationale for this dose of structured exercise is based on national (ADA) and international physical activity recommendations for youth of 60 minutes/day.

Exercise Intervention/Newsletter
NewsletterBEHAVIORAL

Families will receive a monthly newsletter with "parenting tips, sample praise statements, and child-appropriate activities and recipes" identical to what has been used in the work of leaders in the field of pediatric obesity. Previous research suggests that newsletter/mail interventions are well received by participants and are frequently included in federally funded health intervention studies.
