Organised physical activity during leisure time is associated with more objectively measured physical activity among Swedish adolescents

Abstract

Aim: The aim of this study was to investigate associations between participation in organised physical activity (PA), such as sport and exercise during leisure time, and objectively measured PA and sedentary time in a large representative sample of Swedish adolescents.

Methods: This study was part of the school-based cross-sectional Swedish national dietary survey Riksmaten Adolescents 2016-17. Data from 3477 adolescents aged 11-12, 14-15 and 17-18 years were used in the analyses. Participation in organised PA and parental education were reported in questionnaires. PA and sedentary time were objectively measured through accelerometry during seven consecutive days.

Results: Adolescents who participated in organised PA had significantly higher total PA (14%, P < .001), more time spent on moderate-to-vigorous PA (MVPA) (8 minutes, P < .001) and had less sedentary time (15 minutes, P < .001). Those who participated in organised PA were more likely to reach recommended PA levels. Total PA and MVPA did not differ by parental education among those who participated in organised PA.

Conclusion: Adolescents who participated in organised PA were more physically active, less sedentary and more likely to reach PA recommendations than those who did not.
