女性原发性良性阵发性位置性眩晕的骨密度研究

目的探讨女性原发性良性阵发性位置性眩晕(benign paroxysmal positional vertigo,BPPV)和骨密度的关系。方法选取2016年1月~2016年12月在宁波市第二医院神经内科就诊并符合标准的58例女性原发性BPPV患者和84例健康对照者为研究对象。所有入选者均采用双能X线吸收法对腰椎和股骨颈骨密度进行检测。结果 BPPV组中,骨密度正常18例(31.03%),骨密度下降40例(68.97%),其中骨量减少26例(44.83%),骨质疏松14例(24.14%)。对照组中,骨密度正常44例(52.38%),骨密度下降40例(47.62%),其中骨量减少30例(35.71%),骨质疏松10例(11.91%)。2组骨密度下降率比较差异有统计学意义(P0.05)。BPPV组骨密度T值-1.08±1.65明显低于对照组-0.41±1.01,差异有统计学意义(P0.05)。结论女性原发性良性阵发性位置性眩晕的发病可能与骨密度下降有关。

Analysis of bone mineral density in female patients with primary benign paroxysmal positional vertigo

Objective To evaluate the relationship between bone mineral density and female patients with primary benign paroxysmal positional vertigo(BPPV).Methods Fifty-eight primary BPPV and eighty-four healthy women were selected who came to the Department of Neurology Ningbo No.2 Hospital between January 2016 and December 2016.All subject underwent dual X-ray absorptiometry of spine and femur test.Results In BPPV group,the bone mass was normal in 18(31.03%)and reduction in 40(68.97%)of which osteopenia in 26(44.83%)and osteoporosis in 14(24.14%).In control group,the bone mass was normal in 44(52.38 %)and reduction in 40(47.62 %)of which osteopenia in 30(35.71%)and osteoporosis in 10(11.91%).The difference of reduction in the bone mass was statistically significant(P<0.05).Bone density of the BPPV group was significant lower than the control group-1.08±1.65 vs-0.41±1.01,P<0.05].Conclusion BMD reduction may be associated with female primary BPPV occurrence.
