| Effect of: n=378 | Outcome | Direct effects (95% CI) | Indirect effects (95% CI) | Total effects (95% CI) | Proportion of total effect mediated |
| Household assets | SBP via BMI | −0.65 (−1.19 to −0.096)* | 0.08 (−0.04 to 0.19) | −0.56 (−1.12 to −0.02)* | 0.11† |
| BMI via MVPA | 0.27 (0.01 to 0.53)* | −0.01 (−0.04 to 0.01) | 0.26 (−0.005 to 0.53)* | 0.04 | |
| MVPA | −29.51 (−87.81 to 28.78) | −29.51 (−87.81 to 28.78) | |||

Rural Fit Indices: LR test of model versus saturated: χ2 (4)=10.51, probability >χ2=0.03; RMSEA=0.066; CFI=0.72, Comparative Fit Index, SRMR, 0.04: standardised root mean squared residual, CD=0.03, coefficient of determination; TLI, 0.37 Tucker-Lewis Index.
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.
