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.
