Hormone levels in 12- to 15-year-old boys and girls in Spain and their relationship with anthropometric variables

Objective To determine hormone levels in a population-based sample of pubertal children and evaluate their association with anthropometric parameters. Methods Sex steroid levels were assessed using RIA and IRMA. Results In boys, changes in weight and height across the period were accompanied by changes in testosterone and SHBG. In girls, anthropometric variables did not change and were not correlated with estradiol. Conclusions We observed an association between hormone levels and anthropometric changes when active growth associated with puberty was taking place.
