文摘目的观察女性多发性硬化(multiple sclerosis,MS)患者的性功能障碍情况。方法选取2011年6月至2017年12月首都医科大学附属北京天坛医院中医科诊治的76例MS患者作为研究对象。采用电话与电子调查问卷,结合病历资料,收集患者的人口学与临床资料、性功能状况、二便情况等数据进行统计分析。结果 76例被访患者中有53例患者的FSFI评分低于26.5分,女性性功能障碍(female sexual dysfunction,FSD)的发生率为69.7%,FSD组患者平均年龄和发病年龄均显著高于无FSD患者,年龄≥40岁的患者在FSD组所占比例(54.7%)显著高于无FSD组(17.4%),两组间病程、发病次数无显著差异,≥40岁患者FSFI调查量表总得分及性欲、性唤起、阴道润滑、性交痛4个维度单项得分均显著低于<40岁患者,49例存在大便和(或)小便异常(64.5%),Logistic逐步回归分析显示年龄和病程是女性MS患者发生性功能障碍的独立危险因素。结论女性MS患者并发性功能障碍的发生率高,影响患者生活质量。
