Total effect (c) [estimate (SE)]: 2.84 (1.27), p = 0.03
Direct effect (c’) [estimate (SE)]: 2.19 (1.27), p = 0.09
Total indirect effect (∑ab) [estimate (SE); 95 % BCA CI]: 0.62 (0.45); −0.14, 1.69
Adjusted R² = 0.11, F = 3.03, p = 0.001
Adjusted for age, ethnicity, total annual household income and highest level of parental education
^* p < 0.05
^aPath ab coefficients represent 5000 bootstrapped samples, bias-corrected and accelerated coefficients
^bEstimates of ab path are considered significant if the BCA 95 % CI does not cross zero
SE, standard error; BCA 95 % CI, bias-corrected and accelerated 95 % confidence interval; MVPA, moderate-to-vigorous physical activity
