title: Effects of a community-based, professionally supervised intervention on physical activity levels among residents of Recife, Brazil.
abstract: OBJECTIVE
  We evaluated the effects of a community-based intervention, the Academia da Cidade program (ACP), on increasing leisure-time physical activity among residents of Recife, Brazil.
  
  
  METHODS
  We used the International Physical Activity Questionnaire to assess leisure-time physical activity and transport physical activity (i.e., activities involved in traveling from place to place) levels in a random sample of 2047 Recife residents surveyed in 2007. We also examined factors related to exposure to ACP (participation in the intervention, residing near an intervention site, hearing about or seeing intervention activities). We estimated prevalence odds ratios (ORs) of moderate to high leisure-time and transport physical activity levels via intervention exposures adjusted for sociodemographic, health, and environmental variables.
  
  
  RESULTS
  Prevalence ORs for moderate to high levels of leisure-time physical activity were higher among former (prevalence OR=2.0; 95% confidence interval [CI]=1.0, 3.9) and current (prevalence OR=11.3; 95% CI=3.5, 35.9) intervention participants and those who had heard about or seen an intervention activity (prevalence OR=1.8; 95% CI=1.3, 2.5). Transport physical activity levels were inversely associated with residing near an ACP site.
  
  
  CONCLUSIONS
  The ACP program appears to be an effective public health strategy to increase population-level physical activity in urban developing settings.
