How many studies support Daily Step Count?

At least seven independent dose-response meta-analyses published between 2021 and 2024, including a synthesis of 15 international cohorts in The Lancet Public Health and an umbrella review, converge on a consistent pattern: higher daily step counts are associated with progressively lower all-cause and cardiovascular mortality risk, with the steepest risk reduction typically occurring between roughly 4,000 and 8,000 steps per day and more gradual additional benefit beyond that — meaning meaningful benefit occurs well below the popular 10,000-step target, which appears to have originated from a 1960s Japanese marketing campaign rather than research. That's backed by 8 published studies in Vitaebase's database, including 8 meta-analyses, the most recent from 2025 -- a fairly substantial body of research for a single topic.
