Additionally, HOMA-IR exhibited a borderline significant mediating effect between PA and premature mortality (mediation proportion: 10.1%, P = 0.058) (Fig. 4 ).

In contrast, among women in the HLPA group, the reduction in mortality risk (HR = 0.68, 95% CI: 0.42–1.11) did not reach statistical significance.
Regarding cancer mortality, while the LLPA and MLPA groups showed a trend toward reduced risk, the results were inconclusive, likely due to small effect sizes leading to confidence intervals that included the null value.
