Seasonal variation in MVPA (% of wear time) at school, during PE lessons, recess, and lunchtime.

Notes: MVPA, moderate-to-vigorous physical activity; PE, physical education; CI, confidence interval. Findings are presented as regression coefficients and 95% confidence intervals and were based on linear mixed models with school as random effects, and seasons and assessment days as repeated-measure variables. The models were adjusted for sex, grade level, total wearing time and disability type. Statistically significant results are in bold.
