Results of Wilcoxon signed-rank test comparing participants’ physical activity level expressed in MET-minutes at three time points, stratified by physical activity level at baseline (low–moderate–high) and socioeconomic status (very low–low).

Note: SES = socioeconomic status. Physical activity categories were based on the IPAQ scoring protocol [32], while participants’ SES status was categorized according to whether their SES score was below or above the median SES score of the total sample (median SES score = 38.5 units). p-values are presented in bold if significant (p <0.05).
