Note: Unadjusted and adjusted odds ratios (OR) and respective 95% confidence intervals (95%) for the logistic regression models fitted using social support dimensions as the predictors of time on leisure-time physical activity (individuals participating less than three hours per week was the reference group).

n(%) = Number of observations and percentages of individuals that participated in physical activity during their leisure time more than three hours per week, according to each level of social support dimensions.

All statistically significant associations are in bold.
