a
Data are mean ± standard deviation (SD) for normally distributed variables, and median (minimum–maximum) for nonnormally distributed ones.
b
Maximal reported body mass (BM) that a participant reached at any time during their life. One-way ANOVA was used for comparing females across groups. Kruskal-Wallis test was used for comparing males across groups.
