Abstract
To investigate the possible relationship of leptin to bone mineral density (BMD) in men with type 2 diabetes mellitus (T2DM), we screened 168 Belarusian men aged 45–65 years. Plasma total cholesterol (TC), high-density lipoprotein cholesterol, and triglyceride concentrations were assessed, and low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol (LDL-C) were calculated. Hemoglobin A1c, immune-reactive insulin (IRI), serum total testosterone, and sex hormone-binding globulin were also evaluated. BMD was evaluated using dual-energy X-ray absorptiometry. By univariate linear regression analysis, BMD was significantly correlated with body mass index (r = 0.23, P = 0.002) and leptin (r = 0.21, P = 0.006). By multivariate regression analysis adjusting for confounding factors, log leptin was independently correlated with BMD (β = 0.058, P = 0.001). Our study revealed that leptin is an independent determinant of BMD in patients with T2DM. Further research is necessary to confirm this association and to develop ways to correct abnormalities of bone metabolism in patients with T2DM.
