AbstractObjectiveTo describe self-reported physical activity (PA) patterns in the various domains (school, home, transport, leisure time) and intensity categories (walking, moderate PA, vigorous PA) in European adolescents. Furthermore, self-reported PA patterns were evaluated in relation to gender, age category, weight status category and socio-economic status (SES).DesignCross-sectional study.SettingTen European cities.SubjectsIn total, 3051 adolescents (47·6 % boys, mean age 14·8 (sd1·2) years) completed an adolescent-adapted version of the validated International Physical Activity Questionnaire.ResultsThe total sample reported most PA during leisure time (485 min/week) and least PA at home (140 min/week). Boys reported significantly more school-based PA (P< 0·001), leisure-time PA (P= 0·003), vigorous PA (P< 0·001) and total PA (P= 0·002) than girls, while girls reported more home-based PA (P< 0·001) and walking (P= 0·002) than boys. Self-reported PA at school (P< 0·001), moderate PA (P< 0·001), vigorous PA (P< 0·001) and total PA (P< 0·001) were significantly higher in younger age groups than in older groups. Groups based on weight status differed significantly only in leisure-time PA (P= 0·004) and total PA (P= 0·003), while groups based on SES differed in all PA domains and intensities except transport-related PA and total PA.ConclusionsThe total sample of adolescents reported different scores for the different PA domains and intensity categories. Furthermore, patterns were different according the adolescents’ gender, age, weight status and SES.
