title: Renal function is associated with bone mineral density and arterial stiffness in healthy postmenopausal women.
abstract: OBJECTIVE
  This study aimed to investigate the effect of renal function on bone mineral density (BMD) and arterial stiffness in postmenopausal women.
  
  
  METHODS
  This is a retrospective cross-sectional study. We studied 252 postmenopausal women who visited a health promotion center for a medical checkup. The estimated glomerular filtration rate (eGFR) was calculated using the Cockcroft-Gault (CG) formula and the modification of diet in renal disease (MDRD) formula. Areal BMD measurements were performed using dual-energy X-ray absorptiometry, and arterial stiffness was measured using the brachial-ankle pulse wave velocity (baPWV).
  
  
  RESULTS
  The eGFR according to the CG formula was significantly correlated with age, BMI, follicle-stimulating hormone, thyroid-stimulating hormone, high-density lipoprotein cholesterol, baPWV, and BMD at the lumbar spine, femoral neck, and total hip sites. However, the eGFR according to the MDRD formula was significantly correlated with age and baPWV but not with BMD at the lumbar spine, femoral neck, and total hip sites. Decreased renal function (eGFR <60 ml/min/1.73 m(2) according to the CG formula) was independently associated with decreased BMD at the femoral neck site and with increased baPWV (>1,500 cm/s) after adjusting for confounding variables.
  
  
  CONCLUSIONS
  Postmenopausal women with decreased renal function are more likely to have a decreased BMD and greater arterial stiffness.
