Abstract: OBJECTIVE: This study examined differences in (1) psychosocial correlates of physical activity and in (2) physical activity within different contexts and sedentary behaviors between normal weight and overweight adolescents. It further explored whether the prediction of physical activity by the psychosocial correlates is different in normal weight and overweight adolescents. RESEARCH METHODS AND PROCEDURE: A community sample of 6078 11 to 19 year olds from 38 secondary schools, which were randomly selected throughout the country, completed a validated computerized questionnaire about physical activity, sedentary behaviors, and psychosocial correlates. Differences in mean scores on the psychosocial correlates and on the self-rated physical activity were analyzed between the normal weight (n=5563) and the overweight (n=515, 8.5%) group. RESULTS: This study showed that overweight adolescents do less intense physical activities (p<0.001) and have less favorable psychosocial correlates related to physical activity (p<0.001) than their normal weight counterparts. However, the strength of the associations between psychosocial variables and total physical activity were comparable in overweight and normal weight adolescents. More support from family and friends, more fun in physical activity, higher self-efficacy, the perception of more competition benefits, and the perception of less lack of interest were all associated with higher total levels of physical activity. The results suggest that no specific tailoring on psychosocial correlates of physical activity is necessary for overweight adolescents compared with normal weight ones. DISCUSSION: Both overweight and normal weight adolescents can be approached by interventions focusing on the same psychosocial variables to increase physical activity.
