title: Trends in leisure-time physical activity in a southern Brazilian city: 2003-2010.
abstract: BACKGROUND
  Most of physical activity surveillance data are derived from high-income countries. The aim of the current study was to report time trends in leisure-time physical activity.
  
  
  METHODS
  Population-based surveys were conducted in the city of Pelotas, Brazil in 2003 and 2010, including individuals aged 20+ years. Physical activity was assessed using the leisure-time section of the long version of the IPAQ. A cut-off point of 150 min/wk was used in the analyses. Methodologies were virtually identical in both surveys.
  
  
  RESULTS
  In 2003, 26.8% (95% CI 24.3; 29.2) of the participants were classified as active in leisure-time, as compared with 24.4% (95% CI 22.6; 26.2) in 2010. The proportion of subjects reporting 0 minutes per week of walking, moderate- and vigorous-intensity physical activity practice also did not vary between 2003 and 2010. However, the proportion of active adults decreased from 39.9% (95% CI 33.0; 42.7) in 2003 to 29.7% (95% CI 24.9; 34.5) in 2010 among high-income participants. Males were more active than females in both surveys.
  
  
  CONCLUSIONS
  Leisure-time physical activity is stable among adults living in the South of Brazil, but high-income participants are becoming less active over time. Scaling up effective and promising physical activity interventions is urgently needed in Brazil.
