Abstract:
Objective:To identify the risk factors associated with early postpartum pelvic floor muscle strength following cesarean delivery.Methods:A total of 352 women who underwent cesarean section at the Department of Obstetrics and Gynecology,Affiliated Zhongshan Hospital of Dalian University between September 2022 and Sep-tember 2024 and attended a pelvic floor rehabilitation clinic 6 to 8 weeks postpartum were enrolled in this study,and lectromyographic(EMG)values during anterior and posterior resting phases,as well as fast-twitch and slow-twitch muscle phases,were recorded so as to analyze the factors that might affect the pelvic floor strength in the early postnatal period after cesarean section.Factors with statistically significant differences were further ana-lyzed by multifactorial Logistic analysis.Results:Pre-pregnancy body mass index(BMI)＞24 kg/m2,increase in body mass during pregnancy ≥ 11.5 kg,gestational hypertension and term delivery were identified as independent risk factors for abnormal EMG values during the anterior resting phase of the pelvic floor(OR＞1,P＜0.05).In-crease in body mass during pregnancy≥11.5 kg,preterm rupture of membranes,and term delivery were risk fac-tors for abnormal pelvic floor EMG values in the post-resting stage(OR＞1,P＜0.05).Pre-pregnancy BMI＞24 kg/m2 and pre-eclampsia were risk factors for abnormal pelvic floor EMG values in the fast-muscle stage(OR＞1,P＜0.05).and a history of uterine fibroids was a risk factor for abnormal pelvic floor EMG values in the slow-muscle stage(OR＞1,P＜0.05).Conclusions:Early postpartum pelvic floor muscle strength following ce-sarean delivery is influenced by several risk factors,including pre-pregnancy BMI＞24 kg/m2,increase in body mass during pregnancy ≥ 11.5 kg,gestational hypertension,full-term labor,premature rupture of membranes,pre-eclampsia,and history of uterine fibroids,pelvic floor muscle strength is more likely to be impaired in the early postpartum period after the prenatal combination of the above risk factors,and Targeted pelvic floor rehabilitation should be initiated as early as possible during the postpartum period.
