Numbers in cells are β (SE). §A significant interaction (p<0.05) with sex was identified with significant subgroup effects in either boys or girls. $A significant interaction (p<0.05) with sex was identified but subgroups effects were non-significant in both boys and girls. #Where coefficients for boys (B) and girls (G) are reported separately, a statistically significant interaction with sex was retained in the final model. *: p<0.05; **: p<0.01. NS: Not significant; NA: not applicable; PA: physical activity; ref: reference category; TV: television.
