Promouvoir l'activité physique, lutter contre la sédentarité et prévenir le surpoids chez l'adolescent, c'est possible : les leçons d'ICAPS

Based on a socioecological approach, the Intervention Centered on Adolescents' Physical activity and Sedentary behavior (ICAPS), a four-year randomized and controlled trial has shown that prevention of sedentariness and of obesity is feasible in youth thanks the mobilization of several partners including actors in the domains of health, education, physical activity, transport and of community agencies in charge of recreational areas and transportation infrastructures. In this article, we present a synthesis of the key data demonstrating the efficacy of ICAPS at the end of the four years of intervention as well as preliminary results of the six-year follow-up study, i.e. two years after the end of the intervention. We discuss a few tracks on elements that may explain the effectiveness of the strategy implemented.
