Abstract: Objective To analyze the status and influencing factors of spastic pelvic floor syndrome （SPFS） in elderly parturient. Methods From December 2018 to May 2020, the elderly parturient who gave birth in Beijing Daxing District People's Hospital and underwent pelvic floor screening 6-8 weeks after delivery were investigated. The basic information, pregnancy and delivery related data of the subjects were collected by questionnaire survey. The influencing factors of postpartum SPFS were analyzed by univariate and multivariate analysis methods. Results The average age of 500 elderly parturient was （39.84±2.50） years, and the parity was 1 to 4 times, with an average of （2.16±1.04） times. The incidence rate of postpartum SPFS in elderly parturient was 20.60%. The results of multivariate analysis showed that vaginal delivery （OR=3.842）, history of constipation （OR=3.271）, abuse of laxatives （OR=3.656）, second stage of labor ≥2 h （OR=6.052）, local inflammation （OR=2.319）, weight gain during pregnancy ≥20 kg （OR=4.676）, and anxiety （OR=5.658） were risk factors for SPFS, while pelvic floor function exercise （OR=0.242） was a protective factor. Conclusions The risk of postpartum SPFS in elderly parturient is higher, and there are many influencing factors, which need to attract the attention of medical workers and individuals. Targeted measures can be taken to intervene the influencing factors leading to SPFS.
