  1. Unadjusted and adjusted Odds Ratios(OR) and respective 95% confidence intervals(95%) for the logistic regression models fitted using social support dimension as the predictor of time spent on Leisure-time physical activity (reference group: individuals who spent less than 3 hours per week). Pró-Saúde Study, Rio de Janeiro, Brazil (2 years of follow-up).
  2. Fully-adjusted model: Adjusted by age, gender, education, per capita monthly income, tobacco and alcohol use and morbidity.
