Step Count and Longevity After 55: What a Meta-Analysis of 15 Cohorts Found

A meta-analysis of fifteen international cohorts totaling nearly forty-seven thousand adults found that daily step count follows a clear dose-response relationship with all-cause mortality — and that for older adults specifically, the evidence-based target is substantially lower than the ten thousand steps figure that has dominated popular health culture for decades. A meta-analysis published in Lancet Public Health in 2022 pooled data from fifteen international cohorts — over forty-seven thousand adults across multiple countries — to map the relationship between daily step count and all-cause mortality across different age groups. The finding that attracted the most attention was not that more steps are better. It was that the dose-response curve levels off at a threshold that differs substantially between age groups — and that for adults over sixty, the evidence-based plateau sits considerably below ten thousand steps per day.
