We read with interest the recently published Original Investigation by Lee and colleagues regarding the association of step volume and intensity with all-cause mortality using data from the Women’s Health Study. We commend the authors on their pursuit of this question, particularly given the recently identifieddearth of longitudinal evidence related to steps per day and risk of mortality. The findings of Lee and colleagues provide further empirical evidence toward the question of how many steps per day are enough to improve health in adults.
