  1. Note: Model adjusted for prior year depressive symptoms and school clustering. MVPA: moderate-to-vigorous physical activity. ST: screen time. SE: Standard Error
  2. a Baseed on the Canadian 24-h Movement Guidelines (Tremblay et al., 2016)
  3. b Interpret ST results with caution given low frequency of students in 1–1 category (2.1% females; 0.8% males) and males in the 0–1 category (1.6%)
