PurposeStudies describing prevalence and trends of physical activity among workers in the United States are scarce. We aimed to estimate prevalence and trends of \u201csufficient\u201d leisure-time physical activity (LTPA) during the 2004\u20132014 time period among U.S. workers.MethodsData were collected for U.S. workers in the National Health Interview Survey. LTPA was categorized as sufficiently active (moderate intensity, 65150 minutes per week), insufficiently active (10\u2013149 minutes per week), and inactive (<10 minutes per week). Prevalence of LTPA was adjusted for age using 2010 U.S. working population as a standardized age distribution.ResultsPrevalence trends of \u201csufficient\u201d LTPA significantly increased from 2004 to 2014 (45.6% to 54.8%; P < .001). Among industry groups, the highest prevalence of \u201csufficient\u201d LTPA was observed among workers in Professional/Scientific/Technical Services (62.1%). The largest increases were observed among workers in Public Administration (51.3%\u201363.4%). Among occupational groups, \u201csufficient\u201d LTPA prevalence was lowest in farming/fishing/forestry (30.8%) and highest in life/physical/social science (66.4%). Prevalence of LTPA significantly increased from 2004 to 2014 in most occupational and industry groups.ConclusionsAmong U.S. workers, trends of \u201csufficient\u201d LTPA significantly increased between 2004 and 2014. Overall, a larger proportion of white-collar compared to blue-collar workers were engaged in \u201csufficient\u201d LTPA.CC999999/Intramural CDC HHSUnited States/R01 OH010807/OH/NIOSH CDC HHSUnited States
