Key Points Question Are step volume or intensity associated with premature mortality among middle-aged Black and White women and men? Findings In this cohort study of 2110 adults with a mean follow-up of 10.8 years, participants taking at least 7000 steps/d, compared with those taking fewer than 7000 steps/d, had a 50% to 70% lower risk of mortality. There was no association of step intensity with mortality regardless of adjustment for step volume. Meaning This cohort study found that higher daily step volume was associated with a lower risk of premature all-cause mortality among Black and White middle-aged women and men.
