摘要Background:Female sexual dysfunction (FSD) is a highly prevalent and often underestimated problem.However,large-scale,population-based epidemiological surveys of FSD are scarce in China.The present study was conducted to evaluate the prevalence and the potential risk factors of FSD across a selection of social groups in Beijing,China,based on the Female Sexual Function Index (FSFI).Methods:A cross-sectional study based on the multiple-stage cluster sampling was performed with adult women throughout the Dongcheng and Shunyi districts of Beijing.The Chinese version of FSFI was used,as well as questions on demographic characteristics,the disease-related context,and social relationships.Results:A total of 6000 consecutive women entered this study,with an actual response from 5024 women,corresponding to a response rate of 83.7％.A total of 4697 (78.3％) questionnaires were effective.The prevalence of adult FSD in Beijing was 2973 (63.3％) using a score of 26.55 as the boundary value,whereas the total mean FSFI score was 23.92 ± 6.37.However,1423 (30.3％) women did not seek help.By multivariate logistic regression analysis,the possible potential risk factors included age (odds ratio [OR] 1.051),dissatisfaction with the spouse's sexual ability (OR 3.520),poor marital affection (OR =2.087),spouse sexual difficulties (OR =1.720),dissatisfaction with married life (OR =1.476),living in a rural area (OR =1.292),chronic pelvic pain (OR =1.261),chronic disease (OR =1.534),previous pelvic surgery (OR 1.605),vaginal delivery (OR =2.285),lower education (OR 3.449) and postmenopausal (OR =3.183).Conclusions:As suggested by the FSFI scores,female sexual problems are highly prevalent in Beijing.Dissatisfaction with the spouse's sexual ability,poor marital affection,sexual difficulties of the spouse,dissatisfaction with the marriage,rural life,CPP,and postmenopausal were conceivable risk factors for FSD in Beijing women.
