title: Physical inactivity and associated factors among women from a municipality in southern Brazil.
abstract: BACKGROUND
  Physical inactivity is one of the most important modifiable risk factors that is raising the global burden of chronic diseases.
  
  
  METHODS
  This is a cross-sectional, population-based study of 790 women aged 20 years or older living in the urban area of a municipality in Southern Brazil. The level of physical activity was measured using the International Physical Activity Questionnaire, short form. Inactivity was defined as fewer than 150 min/wk-1 spent in moderate or vigorous physical activities. Prevalence ratios were calculated by robust Poisson regression.
  
  
  RESULTS
  The prevalence of physical inactivity was 48.7% (95% CI, 43.3%-54.1%). After adjusting for confounders, we found a linear trend for increasing prevalence of physical inactivity with increasing body mass index (P = .008). Women who were married or in a domestic partnership were 29% less physically active than single women (P = .044). A borderline association was detected between the presence of minor psychiatric disorders (MPD) and physical inactivity (P = .058).
  
  
  CONCLUSIONS
  There was a high prevalence of inactivity. Obese women, those married or in domestic partnerships and those with MPD were more likely to lead an inactive lifestyle. These results suggest that strategies are required for breaking down barriers to physical activity in this demographic group.
