Urinary endogenous steroids and their relationships with BMD and body composition in health young males

Abstract

Some studies have stated that steroid hormones have associations with the values of strength, bone mass density (BMD), and body composition shown by people. In this way, steroid hormonal changes have been directly or indirectly associated with changes in body composition, fat distribution, lean mass, muscle weakness, osteoporosis, as well as depression. Regarding to this topic, most studies have been carried out using blood samples. However, some research has tried to analyze the correlation among urinary steroid hormones and body mass index, fat mass, or BMD. Urinary samples are easy to obtain in sufficient quantities without the need for invasive techniques. Therefore, in this study, we tested the hypothesis that the values of bone mineral density and body composition are related to the values of urinary endogenous steroid excretion (androgens, estro- gens, and corticosteroids).
