  1. Unadjusted and Fully-adjusted Odds Ratios (OR) and respective 95% confidence intervals (95%) for the logistic regression models fitted using social support dimensions as predictors of Engagement in LTPA (reference group: individuals who were inactive at time 1 and did not change their status at time 2) and Maintenance of LTPA (reference group: individuals who were active at time 1 and changed at time 2). Pró-Saúde Study, Rio de Janeiro, Brazil (2 years of follow-up).
  2. n(%) = Number of observations and percentages of individuals who were physically active during their leisure-time according to each level of social support dimension.
  3. Fully-adjusted models: adjusted by age, gender, education, per capita monthly income, tobacco and alcohol use, and morbidity.
