# Daily step count (and mortality)

Daily step count is the total walking steps you rack up in 24 hours, measured by pedometers or wearables that detect vertical motion. It acts as a device-agnostic proxy for your everyday walking activity. It is not the same as structured exercise: most steps are incidental, gathered through ordinary movement. The Paluch 2022 meta-analysis (15 international cohorts, 47,471 adults) mapped the dose-response between steps and all-cause death. The most active quartile (about 10,900 steps a day) had a hazard ratio of 0.47 (95% CI 0.39 to 0.57) versus the least active (about 3,550 steps a day). Spline modeling showed the risk curve flattening around 6,000 to 8,000 steps a day in adults 60 and older, and 8,000 to 10,000 in younger adults, not at 10,000. The famous 10,000-step target has no evidence-based origin. It came from a 1965 Japanese marketing campaign for a pedometer trademarked 'Manpo-kei' (literally '10,000-step meter'). And all the evidence is observational. Cohort studies cannot rule out hidden confounding or reverse causation, and no long-term trial has tested step counts against death.
