Sedentary Time and Physical Activity Across Occupational Classifications

Purpose:To examine differences in activity patterns across employment and occupational classifications.Design:Cross-sectional.Setting:A 2005-2006 Coronary Artery Risk Development in Young Adults (CARDIA) study.Sample:Participants with valid accelerometry data (n = 2068).Measures:Uniaxial accelerometry data (ActiGraph 7164), accumulated during waking hours, were summarized as mean activity counts (counts/min) and time spent (min/d) in long-bout sedentary (≥30 minutes, SED≥30), short-bout sedentary ( .05). Significant differences in mean activity counts and MVPA .05).Conclusion:Time within activity intensity categories differs across employment and occupational classifications and by race and sex.
