^bExponentiated β or geometric mean ratio (GMR) - any deviation from 1 indicates a% difference in moderate and vigorous physical activity (MVPA) relative to the reference category for the given time segment. Final results from a two-level random intercept models adjusted for sex, weight status, time in childcare, age child’s mother left full-time education, time of the week (weekday vs. weekend) and season (Winter: December-February; Spring: March-May; Summer: June-August; Autumn: September-November); *p < 0.05; ** p < 0.01.
