Nutrition and Physical Activity Interventions for Childhood Obesity: Lessons Learned

This article describes field experiences while implementing nutrition and physical activity education in a public junior high school in Puerto Rico (PR). Participants were classified as overweight or at risk based on body mass index (BMI). Dietary intake and weight were collected. Changes in dietary intake assessed from baseline to end of school year did not show statistical significance. The reduction in BMI Z-scores was modest at 4 months and was not observed at the end of the program. Future studies are warranted to integrate parents and behavioral theories and to evaluate food in the environment to successfully address childhood obesity.
