Abstract

Introduction: Child obesity has important consequences on the child’s health and is related to the risk of developing chronic diseases. That brings up the need for research assessing the impact of obesity-and overweight-reduction programs with close attention to methodology aspects and precise indicators of the impact of such programs. Goal: Assessing the impact of a physical activity program on the plasma concentrations of adiponectin, leptin, and ghrelin in overweight and obese schoolchildren. Methods: Randomized controlled trial, double-blind, with 6-to 9-year-old overweight and obese school-children. A sample of 79 schoolchildren randomly distributed into control and intervention groups was subjected to a physical activity program. The levels of adiponectin, leptin, ghrelin, body mass index, body fat percentage, anthropometry, lipid profile and glycemia were evaluated. The program’s impact was assessed through multivariate linear regression models. Result: When comparing the groups, a significant difference was found for adiponectin, which shows an increase in the proportion of subjects with higher adiponectin concentrations for the intervention group and a reduction in body mass index and body fat percentage. Conclusion: The impact of the intervention program was positive in increasing adiponectin levels associated with a reduction in body mass index and body fat percentage.
