Data are given as median (interquartile range) or n (%). For the GWG variables, the total number is <304 due to missing values: n = 144 in the intervention group and n = 148 in the control group. For the physical fitness score, the number is n = 90 in the intervention group and n = 76 in the control group. Differences between groups were analyzed with the χ2 test for categoric variables. The Student t test was used for continuous variables with normal distribution; otherwise, the Mann-Whitney U test was used.
*As an indicator of physical fitness.
