Introduction: Despite theimportance of sexual dysfunction to women’s health, epidemiologicaldata on female sexual dysfunction are hitherto absent inChina.
Objective: We assessed prevalence of female sexualdysfunction in mainland China and its regional and sociodemographicvariations, as well as physiological, pathological, and behavioralrisk factors associated with female sexual dysfunction.
Methods:We conducted a survey of the general female population in mainlandChina between February 2014 and January 2016.Women were randomlyselected withmulti-stage, stratified, cluster sampling. 33805 womenaged 20 to 70 years completed the questionnaire on sexualdysfunction. We used multivariate regression models to examine theeffects of sociodemographic, physiological, pathological, andbehavioral factors on women’s risk of experiencing sexualdysfunction as measured by the Female Sexual Function Index and acutoff score of 23·45.
Results: The prevalence of sexualdysfunction in mainland China ranged 31% -38% in the femalepopulation aged 20 to 70 years. The southwest province Gui zhou hadthe lowest prevalence rate (21%). Non-Han minorities had a lower riskof sexual dysfunction than the Han ethnicity by 34% (95% CI:19%-46%). Diabetes, cancers, gynecological inflammation and pelvicorgan prolapse significantly increased the risk by 22%(95% CI:7%-40%), 53% (adjusted 95% CI: 15%-103%), 35% (95% CI: 23%-48%) and32% (95% CI: 18%-48%), respectively.
Conclusions: Theprevalence rate of female sexual dysfunction in mainland China wasmodest overall, but its regional and sociodemographic variationsweresubstantial. Women with diabetes, cancers, gynecologicalinflammation or pelvic organ prolapse had higher risksof experiencingsexual dysfunction. Further studies are needed to evaluate theresponse pattern ofthe Female Sexual Function Index and to explainthe regional and ethnic variations of sexual dysfunction in theChinese population.
