title: Worksite physical activity policies and environments in relation to employee physical activity.
abstract: OBJECTIVE
  Examine associations between worksite physical activity promotion strategies and employees' physical activity and sedentary behaviors.
  
  
  METHODS
  Cross-sectional.
  
  
  METHODS
  Seattle-King County, Washington and Baltimore, Maryland-Washington, D.C. regions.
  
  
  METHODS
  Adults working outside the home (n = 1313). Mean age was 45 ± 10 years, 75.8% of participants were non-Hispanic white, 56% were male, and 51% had income ≥$70,000/year.
  
  
  METHODS
  Participants reported demographic characteristics and presence/absence of nine physical activity promotion environment and policy strategies in their work environment (e.g., showers, lockers, physical activity programs). A worksite physical activity promotion index was a tally of strategies. Total sedentary and moderate-to-vigorous physical activity (MVPA) min/d were objectively assessed via 7-day accelerometry. Total job-related physical activity minutes and recreational physical activity minutes were self-reported with the International Physical Activity Questionnaire.
  
  
  METHODS
  Mixed-effects models and generalized estimating equations evaluated the 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 higher total sedentary behavior (β = 3.97), MVPA (β = 1.04), recreational physical activity (β = 1.1 and odds ratio = 1.39; away from work and at work, respectively) and negatively with job-related physical activity (β = .90).
  
  
  CONCLUSIONS
  Multiple worksite physical activity promotion strategies based on environmental supports and policies may increase recreational physical activity and should be evaluated in controlled trials. These findings are particularly important given the increasingly sedentary nature of employment.
