Data are means ± SD.

*

Skewed variables are presented as median (interquartile range). The groups were compared using Mann-Whitney U tests for skewed variables and unpaired t tests for normally distributed variables. Changes in body composition variables in each group were examined with paired t tests. There were no significant differences between the groups in body composition variables at baseline or follow-up or in 1-year change. SDS, standard deviation score.
