Abstract: 【Abstract】 Objective To discuss the pelvic floor muscle function and its influencing factors in parturient women. Methods A total of 1 000 postpartum parturiums who underwent pelvic floor muscle function testing in Central Hospital of Enshi Tujia and Miao Autonomous Prefecture from December 2016 to June2018 were selected as the research subjects. The clinical data were collected and the muscle strengthand fatigue of pelvic floor Ⅰ type muscle fibers and sub-type muscle fibers were detected to analyze theinfluencing factors of postpartum pelvic floor muscle dysfunction. Statistical analysis was performed using ttest, χ2 test and logistic regression analysis. Results Among 1 000 postpartum women, the abnormal rates of muscle strength of class Ⅰ and Ⅱ muscle fibers were 65.20% and 59.20%, respectively; the abnormal rates of fatigue were 90.30% and 91.00%, respectively. Vaginal dynamic pressure abnormality rate was 66.60%. The abnormal rate of pelvic floor muscle detection in vaginal delivery was higher than that of cesarean delivery (all P<0.05). The univariate analysis results showed that the age, delivery method, the mode of delivery, the time of the second stage of labor and the history of pelvic surgery were related to the abnormal muscle strength of type I muscle fibers (P<0.05). The mode of delivery, fetal weight (cesarean section) and weight gain during pregnancy were related to the abnormality of type Ⅰ muscle fiber fatigue (P<0.05). The mode of delivery,times of delivery, mode of cesarean section and times of cesarean section were related to class Ⅱ muscle fiber and muscle strength abnormality (P<0.05). The mode and times of delivery were related to the abnormal fatigue degree of type Ⅱ muscle fiber (P<0.05). The mode of delivery and the number of cesarean section were related to the abnormal vaginal dynamic pressure (P<0.05). The results of logistic regression analysis showedthat, the times of delivery, high fetal weight and cesarean section, weight gain during pregnancy and the history of pelvic surgery were the risk factors for the abnormal muscle strength of type Ⅰ muscle fibers (OR=3.110,2.975, 2.793, 3.054, 2.896; 95%CI: 1.596-6.068, 1.516-5.830, 1.315-5.936, 1.445-5.474, 1.258-4.865; allP<0.05). The times of delivery, high fetal weight and cesarean section were the risk factors of postpartumtype Ⅱ muscle strength decline (OR=2.759, 7.594, 1.593; 95%CI: 1.520-5.008, 1.262-45.698, 1.136-2.232; allP<0.05). The cesarean section, the long time of the second stage of labor and the times of cesarean section werethe risk factors of abnormal vaginal dynamic pressure (OR=4.875, 2.759, 1.698; 95%CI: 0.416-4.657, 1.458-4.656, 1.121-2.121; all P<0.05). Conclusion Postpartum women are prone to pelvic floor muscle dysfunction, which is mainly related to obstetric factors such as number of deliveries, fetal weight, delivery mode, weight gain during pregnancy and history of pelvic surgery.
