BOUNCE to Health: A Healthy Lifestyle Program

Study Overview
=================
Brief Summary
-----------------
The primary purpose of the BOUNCE study is to assess the effectiveness of a four-week family-based healthy lifestyle summer program in reducing adiposity indicators in Hispanic and African American girls and boys (ages 9-14 years old).

Detailed Description
-----------------
The secondary aims of this study are to examine post-intervention changes in eating patterns, body image disturbances, unhealthy weight control practices, and fitness levels. The investigators hypothesize that at the post-BOUNCE summer intervention, children will exhibit significant decreases in adiposity indicators (percent body fat and waist circumference), sweetened drinks and fried foods consumption, and an increase in physical fitness (aerobic capacity and minutes of moderated-vigorous physical activity) when compared to their baseline values after controlling for demographic, acculturation characteristics.

Eligibility Criteria
-----------------
Inclusion Criteria: Both parental guardians (mother and father) and target child must be of Hispanic or African American descent Child must be between the ages of 9-14 years Child must be overweight/obese as defined by a body mass index percentile for age- gender specific between the 85th-100th percentile Child must have no physical disability or medical conditions that interfere with their participation in an exercise program Children must have no extensive diet restrictions that would hinder their participation in the BOUNCE nutrition component (e.g., unable to eat solid foods) All children will be required to submit evidence of a medical examination conducted by a health professional Parental guardians and child must be available to participate for the duration of the BOUNCE summer Exclusion Criteria: Child and parental guardians are not Hispanic or African American Child is not between the ages of 9-14 years Child is underweight or normal weight (BMI < 85 percentile) or are morbidly obese (BMI > 100 percentile) Child or mother are pregnant or physically unable to participate Child has extensive diet restrictions that would hinder their participation in the BOUNCE nutrition component (e.g., unable to eat solid foods) Child does not have submitted evidence of a medical examination conducted by a health professional Note: We will encourage both maternal and paternal guardians to participate in the measurements and interventions. However, if the paternal guardian refuses to participate or there is no father figure present in the family, maternal guardian-child pairs will be still eligible to participate in this study. If the children are of mixed race, but identify themselves as Hispanic or African American and at least one of their parents is either Hispanic or African American, they will be still eligible to participate.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention<br>Child participants will attend the healthy lifestyle summer program for 4 weeks, five days per week. The summer intervention will include daily one-hour nutrition education, one-hour behavioral counseling, and 3 one-hour exercise sessions. These physical activities include flexibility, games, traditional fitness, and dancing. Counseling and school psychology students, registered dietitian/nutrition educators, and fitness specialists will lead the respective sessions. Parental guardians will participate in a two-hour weekly parental sessions that involve: 1)nutrition education with cooking demonstrations of healthy recipes; 2)behavioral counseling to learn effective parenting strategies on how to support their child's healthy nutrition and exercise habits and goals; and 3)exercise sessions where parents will engage in different physical activities and will receive fitness tips on how to promote an active lifestyle for the entire family. | Behavioral: Intervention<br> <br> |
