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

Objective: To compare androgens and sex hormone-binding globulin (SHBG) levels, and indices of insulin sensitivity (the response of plasma insulin and C-peptide in OGTT, insulin resistance and beta-cell activity estimated with the homeostasis assessment model (HOMA model) in healthy obese premenopausal women with different body fat distributions.

Patients And Methods: Free testosterone, androstenedione, SHBG levels and responses of plasma glucose, insulin and C-peptide in OGTT were examined in 74 healthy premenopausal women (19 with lower-body obesity (WHR < 0.80), 20 with pure abdominal obesity (WHR > 0.
