Total osteocalcin in serum predicts testosterone level in male type 2 diabetes mellitus

摘要

Objective: To investigate the relationship between total osteocalcin (total OC) and testosterone level in the serum of male patients with type 2 diabetes mellitus (T2DM). Methods: 98 male T2DM were recruited in our cross-section study. Their anthropometric parameters were measured and body mass index (BMI) was calculated. Serum markers including glucose, insulin, HbA1c, testosterone, total OC and other bone metabolic markers were examined. Simple Pearson correlation and multiple regression analysis were performed. Results: Poor level of glucose control was found in the patients (HbA1c 9.19±2.53 and FPG 8.20±2.98). In simple Pearson correlation, total OC was positively related with testosterone (r=0.236, P=0.019), and this relation still existed after considering all the parameters of the patients (Model 1, 2 and 3). Conclusion: In male patients with T2DM, total OC was positively correlated with testosterone, so total OC might predict the testosterone level in the serum.
