title: Sedentary behaviors, leisure-time physical inactivity, and chronic diseases in Brazilian workers: a cross sectional study.
abstract: BACKGROUND
  Our purpose was to examine the association of television viewing (hours/day), sedentary work (predominantly sitting at work), passive transportation to work (car or motorcycle), and the clustering of these behaviors ("sedentary lifestyle"), as well as leisure-time physical inactivity (LTPI), with chronic diseases (hypertension, hypercholesterolemia, type 2 diabetes, obesity, and clustering of chronic diseases) in Brazilian workers.
  
  
  METHODS
  Cross-sectional study conducted from 2006 to 2008 in 24 Brazilian federal units (n = 47,477). A questionnaire was applied. Descriptive statistics, binary and multinomial logistic regressions were used.
  
  
  RESULTS
  Magnitude of association with chronic diseases varied greatly across domains and gender. Sedentariness at work was the most consistent behavior associated with chronic diseases, especially in men (OR hypertension = 1.10, 95% CI: 1.01-1.20; OR hypercholesterolemia = 1.34, 95% CI: 1.21-1.48; OR obesity = 1.27, 95% CI: 1.15-1.41; OR1 chronic disease = 1.17, 95% CI: 1.09-1.26; OR ≥ 2 chronic diseases = 1.61, 95% CI: 1.46-1.78) compared with women (OR hypercholesterolemia = 1.15, 95% CI: 1.01-1.31; OR obesity = 1.24, 95% CI: 1.04-1.48). LTPI was associated with all diseases in men (except type 2 diabetes), but only with obesity in women.
  
  
  CONCLUSIONS
  Adverse health consequences may be differently associated according to behavior domain and gender. Sedentary work and LTPI were consistently associated with chronic disease in Brazilian workers, especially in men.
