Purpose. Examine associations between worksite physical activity promotion stra tegies and employees’ physical activity and sedentary behaviors. Design. Cross-sectional. Setting. Seattle–King County, Washington and Baltimore, Maryland–Washington, D .C. regions. Subjects. Adults working outside the home (n 5 1313). Mean age was 45 6 10 years, 75.8% of participants were non-Hispanic white, 56% were male, and 51% had income § $70,000/year. Measures. Participants reported demographic characteristics and presence/absen ce of nine physical activity promotion environment and policy strategies in their w ork environment (e.g., showers, lockers, physical activity programs). A worksite physical activity prom otion index was a tally of strategies. Total sedentary and moderate-to-vigorous physical activit y (MVPA) min/d were objectively assessed via 7-day accelerometry. Total job-related physical activity m inutes and recreational physical activity minutes were self-reported with the International Physical Act ivity Questionnaire. Analysis. Mixed-effects models and generalized estimating equations evaluated th e association of the worksite promotion index with physical activity and sedentary behavior, adjusting for demographics. Results. A higher worksite promotion index was significantly associated with high er total sedentary behavior ( b 5 3.97), MVPA ( b 5 1.04), recreational physical activity ( b 5 1.1 and odds ratio 5 1.39; away from work and at work, respectively) and negatively with job-related physical activity ( b 5 .90). Conclusions. Multiple worksite physical activity promotion strategies based on envir onmental supports and policies may increase recreational physical activity and sh ould be evaluated in controlled trials. These findings are particularly important given the increasingl y sedentary nature of employment
