menopausal status, and glucose tolerance in endocrinology outpatients. Material and Methods: A total of 178 endocrinology outpatients with oral glucose tolerance test (OGTT) findings were included. Data on anthropometrics [body mass index (BMI), waist circumference (cm), body fat percentage (BFP), and fat mass], glycemic parameters [fasting blood glucose (FBG), insulin), C-peptide, HbA1c, and insulin resistance (HOMA-IR)], blood lipids, and serum osteocalcin (OCN) levels [total osteocalcin (tOCN) and uncarboxylated osteocalcin (uOCN)] were compared with sex, menopausal status, and glucose tolerance status. Results: No significant difference was noted in the tOCN and uOCN levels concerning gender and menopausal status. tOCN was negatively correlated with BMI, waist circumference, BFP, and fat mass in patients with normal glucose tolerance (p
