β values are standardized regression coefficients. Analyses were adjusted for sex, peak height velocity (year) and parent education university level (neither/one/both). Statistically significant values are shown in bold (P < 0.05). Combined physically active patterns were calculated as the sum of performing active commuting to school and physical activity before school
