OBJECTIVE To investigate the correlation between benign paroxysmal positional vertigo (BPPV) and bone mineral density (BMD) in menopausal women with BPPV.METHODS 50 patients between the ages of 50-80 years old of menopausal women with Idiopathic benign paroxysmal positional vertigo(iBPPV)as case group,and postmenopausal healthy people of same age doing physical examinations in hospital medical examination center were selected as control group.The lumbar spine(L1-L4) and femoral neck were measured respectively using dual energy X-ray absorptiometry and expressed in T value.The case group and the control group were divided into three age groups,and the T values of three age groups were statistically analyzed.RESULTS There was significant correlation between the case group and control group(The t values are-3.68、-5.98 and-3.33,respectively,P＜0.05).Pearson correlation analysis showed that there was a negative correlation between iBPPV and bone mineral density(BMD) (r=-0.496,P＜0.05).CONCLUSION There was a correlation between benign paroxysmal positional vertigo and BMD in menopausal women.The results of this study may be helpful for the diagnosis,treatment,prognosis and precaution of iBPPV.
