Footnote: ***p < 0.001; **p < 0.01; *p < 0.05; non-significant interactions are not reported. β, Exponentiated beta coefficients; CI, confidence interval; MVPA, moderate-to-vigorous physical activity. The models were adjusted for age, neighbourhood type (and sex in models for whole sample) with distance to school as a modifier.
