Note: Unadjusted and adjusted odds ratios (OR) and respective 95% confidence intervals (95%CI) provided by multinomial regression models fitted using social support dimensions as predictors of type of leisure-time physical activity (reference group: individuals who were active in phase 1, but not in phase 2).

n(%) = Number of observations and percentages of individuals who participated in individual and group physical activity during their leisure time, according to each level of social support dimensions.

All statistically significant associations (p < 0.05) are in bold.
