Meta-analysis
~9% lower mortality per 1,000 additional steps/day in 2024 meta-analysis; nonlinear benefit
Systematic review & meta-analysis
Any resistance training vs none associated with 15% lower all-cause mortality (RR 0.85, 95% CI 0.77–0.93); dose-response peaked at ~60 min/week (27% reduction)
Observational study
Large IPD analysis: mortality lowest around or below 100 g ethanol/week; higher intake progressively associated with lower life expectancy
Meta-analysis
U-shaped; ~7 h/night lowest risk; 9–11 h associated with materially higher mortality in meta-analysis
Observational study
Highest vs lowest activity roughly 25–35% lower mortality in major prospective meta-analyses
Cohort study
Never smoker = reference; current smoking ~2.18–2.81× mortality in large cohorts; former smokers can approach never-smoker risk after prolonged cessation
