Insulin resistance and androgens in healthy women with different body fat distributions.

Abstract

In healthy premenopausal women, increased BMI and more pronounced abdominal fat accumulation was associated with increased androgenic activity (higher free testosterone and lower SHBG levels) and with insulin resistance estimated using the HOMA model, as well as with increasing basal and glucose-induced insulin levels. SHBG levels correlated with insulin and insulin resistance independently of the degree of obesity, obesity type and androgens, whereas beta-cell function correlated only with free testosterone.
