An Estimate of Physical Activity Prevalence in a Large Population-Based Cohort

Abstract

These data demonstrate 1) greater prevalence of sufficient moderate and vigorous PA and lower prevalence of sedentary behavior in this sample compared with adults nationwide, 2) a greater association between vigorous PA and improved health outcomes than was observed for moderate PA, 3) PA guidelines must focus on both frequency and duration of activity, and 4) age and education gradients in moderate and vigorous PA that could have implications for more effective targeting of guidelines to improve the PA prevalence of American adults.
