Relationship between metabolic syndrome and bone mineral density in the postmenopausal women / 대한산부인과학회지

ABSTRACT

OBJECTIVE: Observational studies suggest that osteoporosis is associated with cardiovascular disease, although another study found that metabolic syndrome (MS) has protective effects on bone. Therefore, this study examined the relationship between metabolic syndrome and bone mineral density (BMD) in postmenopausal women. METHODS: We divided postmenopausal women who visited St. Vincent Hospital of the Catholic University of Korea in 2006 and 2007 into groups with and without MS and measured their body mass index (BMI), waist-hip ratio (WHR), blood pressure, serum fasting glucose, lipid profile, and BMD of the lumbar spine and femoral neck. RESULTS: Of the 151 subjects, 66 (43%) had MS and 85 (57%) did not. The women with MS had a higher BMD at the lumbar spine and femoral neck, although after adjusting for age and BMI, this correlation was lost. Significant positive correlations were observed between BMD of the lumbar spine and both high-density lipoprotein (HDL) cholesterol and serum fasting glucose, and BMD of the femoral neck was positively correlated with serum fasting glucose level. The components of MS were not correlated with BMD in these postmenopausal women after adjusting for age and BMI. CONCLUSION: In our study, the higher BMD in MS was explained by the higher BMI in postmenopausal women. After adjusting for age and BMI, however, MS had no protective effect on bone mass. MS may be another risk factor for postmenopausal osteoporosis.
