Abstract:
Objective To evaluate the effect of gestational weight gain(GWG)on the labour process and delivery mode in primiparas undergoing epidural analgesia(EA).Methods The medical records of all primiparas with singleton term deliveries who received EA at Obstetrics and Gynecology Hospital,Fudan University from Aug 2020 to Jan 2021 were retrospectively collected.The effects of excessive GWG on labor process and mode of delivery were evaluated using t tests and χ2 tests.Multivariate regression and multinomial logistic regression analyses were employed to examine the impact of various factors on labor process and mode of delivery.Results A total of 1 283 primiparas were included in the study,with 646 cases in the excessive GWG group(study group)and 637 cases in the inadequate/adequate GWG group(control group).Before propensity score matching(PSM),the study group exhibited higher pre-pregnancy BMI values,longer gestational age,and more comorbidities compared to the control group(P<0.001).After PSM,GWG had no statistically significant impact on the labor process or mode of delivery.Multivariate regression analysis showed that oxytocin had significant effects on the first stage of labor(P=0.001),the second stage of labor(P<0.001),and mode of delivery(P=0.002).Gestational age(P=0.003)had a significant impact on the first stage of labor,while the mode of membrane rupture(P=0.003)and coexisting diabetes(P=0.015)had significant effects on the second stage of labor.Age(P<0.001)and gestational age(P=0.019)had significant effects on the mode of delivery.Conclusion Among nulliparous women receiving EA,there were no statistically significant differences in the labor process and mode of delivery between those with excessive GWG and those with inadequate/adequate GWG.
