The sexual function of the subjects was evaluated according to female sexual function indexes, dyspareunia indicated by sexual pain score < 4.4, and the results analyzed by multiple logistic regression analysis.

Totally, 1 856 (69.8%) of the subjects completed the questionnaire, and 1 457 that met the criteria were included for analysis, of whom 43.0% (626/1457) admitted to dyspareunia during the sexual intercourse. Multiple logistic regression analysis showed that age (> or = 50 years) , smoking, hysterectomy, vaginal lubrication disorder, lack of sexual communication with partners were independent risk factors for dyspareunia (P < 0.05).
