Key result
Adherence to all four healthy lifestyle behaviors was associated with a 36% lower risk of all-cause mortality (HR 0.64) and a 47% lower risk of cardiovascular mortality (HR 0.53) compared to zero healthy behaviors.
Why the study?
Knowledge gaps remained regarding the distribution, associated factors, and potential mortality benefits of four healthy lifestyle behaviours in China.

Supports promoting the four behaviors in Chinese adults; leaves open whether interventions can raise low adherence or confirm causality.

Does adherence to four healthy lifestyle behaviours reduce all-cause and cardiovascular mortality in Chinese adults aged 35-75 years?
Hazard Ratio: 0.64 (95% CI 0.52–0.79)

Adherence to four healthy lifestyle behaviors (non-smoking, moderate alcohol, physical activity, healthy diet) significantly reduces all-cause and cardiovascular mortality in Chinese adults, though overall adherence is very low at 2.8%.
Zhang et al. (2021) conducted a cohort in General population (n=903,499). Adherence to four healthy lifestyle behaviors (non-smoking, moderate alcohol, sufficient physical activity, healthy diet) vs. Zero healthy lifestyle behaviors was evaluated on All-cause mortality (HR 0.64, 95% CI 0.52, 0.79, p=<0.001). Adherence to all four healthy lifestyle behaviors was associated with a 36% lower risk of all-cause mortality (HR 0.64) and a 47% lower risk of cardiovascular mortality (HR 0.53) compared to zero healthy behaviors.
