Do boys and girls achieve di!erent results?" Changes in physical activity and adiposity: acorda project. In XXVIII Pediatric Work Physiology PWP 2013. Coimbrahttp://hdl.handle.net/10198/10631School-based interventions show inconsistent results in reducing obesity-related problems. Most of intervention studies are targeting girls because they have shown lower rates of physical activity and higher prevalence of obesity. ! The aim of this study was to compare the changes observed in BMI, percentage of Body Fat, percentage of Trunk Fat and Moderate to Vigorous physical activity (MVPA) levels between boys and girls engaged in a school-based intervention program.Significant improvements in body composition and MVPA levels were observed in boys, but not in girls, after 8 months intervention. In accordance with previous findings, these results showed that gender may influence response to intervention programs and generalization of treatment effects may depend on gender-specificities and programs characteristics.!engPhysical activityAdiposityconference object
