  1. Note. 2,249 daily observations were clustered within 417 adolescents. Results express the between- and within- relationship of daytime minutes in MVPA and night sleep variables while adjusting for covariates.
  2. MVPA is moderate-to-vigorous physical activity. Biomother, Biofather = Biological Mother and Biological Father. BMI is body mass index.
  3. *p < 0.05, **p < 0.01, ***p < 0.001.
