In elderly men, osteocalcin was reported to correlate inversely with fat mass.Aim: To examine the relationship between osteocalcin and regional fat depots.Method: The Odense Androgen Study is a population-based, cross-sectional study of 779 randomly selected men aged 20–29 years. Total, central, upper ex...

Background: Central obesity in polycystic ovary syndrome (PCOS) is associated with increased inflammatory markers and increased risk for type 2 diabetes.Aim: To evaluate the long-term effects of metformin (M) and/or oral contraceptives (OC) on fat mass.Research design: Randomized, controlled study.Setting: Outpatient clinic.Methods: 90 patients with PCOS were randomized to 12 months M (...

Background: PPARγ-agonist treatment may decrease bone mineral density (BMD) in postmenopausal women. The hypothesis that premenopausal women are relatively protected from mineral loss during PPARγ-agonist treatment has not been evaluated in clinical studies.Aim: To investigate the effect of pioglitazone on BMD and bone turnover markers in patients with polycystic ovary syndrome (PCOS).Methods: Thirty premenopausal PCOS pa...

Objective: To investigate the effect of pioglitazone on cortisol metabolism in PCOS.Design: Thirty insulin resistant PCOS patients were randomized to either 16 weeks of pioglitazone (30 mg/day) or placebo treatment. Before and after intervention, patients underwent 24 h 20 min.-integrated blood sampling for measurement of cortisol and 24 h excretion of cortisol, cortisone and steroid metabolites (cortisol, corticosteron, androgen, and 17-hydroxyprogester...
