Effects of lifestyle intervention on psychosocial adjustment in obese children

Objective The aim of this study was to evaluate the relationship between changes in physical activity (PA), sedentary behavior, and physical self-perceptions and body image in 104 overweight and obese children. The age of the children ranged from 9 to 11 years. Participants and methods A trial was designed to increase PA and reduce sedentary behavior. PA was reported by screen time more than 3 h/day for 8 weeks. Sedentary behavior was defined as minutes per day spent in television (TV) viewing, video game, and mobile phone. Results Increases in PA were associated with increases in body image (P<0.00) and body satisfaction (P<0.003). Reduction in TV viewing was also related to increased physical self-worth. Conclusion Increases in PA are associated with improvements in physical self-perceptions, whereas reductions in TV viewing are associated with increased physical self-worth, and these psychosocial benefits appear to be independent of change in adiposity.
