- Model 1: Adjusting for age and sex and clustering (sibling-pairs). Model 2: Adjusting for age, sex and other physical activity participation (sedentary, light, MVPA) and clustering (sib-pair)
- Sedentary activity = time spent in activities <1.5 MET; light activity = time spent in activities 1.5-3 METS; MVPA = time spent in activities >3 MET
-
aCategories reflect increasing total activity (MET hr/day), with category 1 as baseline (least activity)
-
bCategories reflect increasing time spent in specific activity intensity with category 1 as baseline (least time). p -values are from linear regression analyses * p < 0.05; ** p < 0.001
