Is leptin a significant predictor of bone mineral density in postmenopausal Turkish women?
The objective of the present study was to investigate the relationship between leptin and bone mineral density in postmenopausal Turkish women. A total of 122 healthy postmenopausal women were enrolled in this cross-sectional study. Blood samples were obtained for analysis of serum leptin. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry at the lumbar spine, femoral neck and trochanter on the same day. Leptin levels was significantly correlated with BMD of L(1-4) (P = 0.04), but not of femoral neck (P = 0.13), and trochanter (P = 0.39). However, Z scores of L(1-4) (P = 0.009), femur neck (P = 0.009), and femur trochanter (P = 0.025) were positively correlated with leptin levels. In multiple linear regression analysis, leptin was not found to be a statistically significant independent predictor for BMD. Leptin was associated with BMD and Z scores at various body sites; however, it was not an independent predictor of BMD.
