Results are presented only for men in this table as pubertal development was the only factor significant for women in univariate analysis, thus no model could be built in multivariate analysis.

^†

Overweight was defined using age- and sex-specific international cut-offs for BMI for <18 years⁽ ⁴⁶ ⁾ and ≥18 years⁽ ⁴⁸ ⁾.
