One size does not fit all: identifying clusters of physical activity, screen time, and sleep behaviour co-development from childhood to adolescence

摘要: Canada was the first to adopt comprehensive 24-h movement guidelines that include recommendations for physical activity, screen time and sleep promote health benefits. No studies have investigated concurrent development of these behaviours in youth. The objectives were assess adherence Canadian children youth estimate co-development self-reported moderate-to-vigorous intensity activity (MVPA), during 8-years from childhood adolescence. Nine hundred twenty three participants MATCH study their MVPA, duration at least twice over 8 years. MVPA measured times per year (24 cycles), once (8 cycles). Guideline dichotomised as meeting each specific behaviour recommendation or not. Multi-group trajectory modeling used identify unique trajectories behavioural co-development. Analyses stratified by sex. Between 10 39% did not meet any various cycles data collection. More than half met only one two recommendation, roughly 5% all more cycle throughout 8 years follow-up. Four different identified boys girls. For girls, a complier (good guideline recommendations; 12% 9% girls), decliner (decreasing 23% 18% girls) non-complier group (low 42% identified. In boys, MVPA-complier (high MVPA-low time; 23%) identified, whereas girls screen-complier (moderate time-low MVPA; 30%) There is need recognise variations general trends decreasing increasing exist. Specifically, we found although it uncommon adhere guidelines, some displayed high likelihood attaining multiple recommendations. Further, patterns can differ across sub-groups
