Title: LA Sprouts: The Impact of Gardening and Nutrition Education on Childhood Obesity in Latino Youth
Brief Summary: The overall goal of this project is to conduct a randomized controlled 12-week after school, gardening, nutrition and cooking program (called "LA Sprouts") to improve dietary intake and reduce obesity in 3rd, 4th and 5th grade students (ages 8-12 years) in Los Angeles. Approximately 400 3rd - 5th grade students participating in the LA's Best after school program will participate. Four elementary schools in Los Angeles will be selected to participate in the study. Schools will be randomized by region to either receive the intervention (LA Sprouts; 2 schools, n=200 students) or serve as controls (received a delayed intervention program one school semester later; 2 schools, n=200 students). The LA Sprouts intervention will take place at the elementary schools, with gardens on campus specially designed and built for this project. The program will be held once a week for 12 weeks and will consist of a 45-minute gardening lesson, taught by Master Gardeners from the University of California Cooperative Extension (supervised by Nicole Gatto, MPH, PhD), and a 45-minute nutrition education and cooking lesson, taught by USC a Nutrition Educator (supervised by Jaimie Davis, PhD, RD). Measures of childhood obesity (i.e., body mass index (BMI) and body fat percentages), blood pressure, metabolic function (fasting blood glucose, insulin and lipids), dietary intake and related behaviors, and school performance will be measured before and after the implementation of the program in both intervention and control participants. Approximately 10 additional students of the same age will be asked to participate in a focus group to evaluate the questionnaire developed for this study. In addition, approximately 20 additonal students of the same age will be asked to participate in a test-retest session to validate the reliability of the questionnaire.
