dc.description.abstractAbstract: We describe physical activity trajectories during secondary school and examine the association with change in adiposity in youth aged 12-13 years at baseline. Physical activity was measured in 20 survey-cycles over 5 years; anthropometrics were measured in survey-cycles 1, 12 and 19. Complete data on 840 and 760 adolescents followed from survey-cycles 1-12, and survey-cycles 12-19, respectively, were available. Individual growth curves modeling moderate-to-vigorous physical activity (MVPA), and vigorous physical activity (VPA), were estimated. Estimates of initial level and rate of decline in each of MVPA and VPA bouts/week were included as potential predictors of body fat % and BMI in sex-specific linear regression models. Among girls, a yearly decline of 1 MVPA bout/week during earlier adolescence was associated with an increase of 0.19 (95% CI: 0.02, 0.36) units of body fat %, and a yearly decline of 1 VPA bout/week was associated with an increase of 0.47 (95% CI: 0.015, 0.92) units of body fat %. In boys, a yearly decline of 1 MVPA bout/week during later adolescence was associated with an increase of 0.38 (95% CI: 0.05, 0.70) units of body fat %. Initiation and adherence to moderate and vigorous intensity activity should be promoted during secondary school.fr
