Higher objectively measured daily step counts are linearly associated with lower all-cause mortality in free-living adults, with increasing steps from sedentary levels to 10,000 per day reducing mortality risk by 46%.
To reduce your long-term mortality risk, focus on increasing your daily step count. If you are currently sedentary, aiming for 10,000 steps per day can reduce your risk of death by nearly half over a decade. You do not need high-intensity exercise; simply walking more throughout your day provides substantial protection.
Higher daily step count at baseline was linearly associated with lower all-cause mortality (adjusted hazard ratio AHR, 0.94; 95% CI, 0.90 to 0.98 per 1 000 steps; P = 0.004). Increasing baseline daily steps from sedentary to 10 000 steps a day was associated with a 46% (95% CI, 18% to 65%; P = 0.004) lower risk of mortality in the decade of follow-up.
Why this rating
Large prospective cohort study (n=2,576) with long-term follow-up (>10 years) and objective measurement, though observational design limits causal inference compared to RCTs.
