Pooled Fit Indices: LR test of model versus saturated: χ² (4)=24.829, probability >χ²=0.000; RMSEA=0.077; CFI=0.89, Comparative Fit Index; TLI=0.75, Tucker-Lewis Index; SRMR=0.033: standardised root mean squared residual, CD=0.137, coefficient of determination.

Adjusted for age; *P<0.05; **P<0.01; ***P<0.001.

†Assessed using the absolute values for both indirect and direct effects.

BMI, body mass index; LR test, likelihood ratio test; MVPA, moderate and vigorous intensity physical activity; RMSEA, root mean squared error of approximation; SBP, systolic blood pressure; SES, socioeconomic status.
