Data are presented as mean ± SD. The z-score is a quantitative measure of the deviation of a specific variable taken from that population's mean. Centers for Disease Control and Prevention z-height takes age and sex into account. Significance was indicated for values with P < .05.

Significant interaction with time (2-way ANOVA with repeated measures at one of the factors; Bonferroni post hoc test).
