The effect of individualized exercise guidance during pregnancy on the mode of delivery in primipara
Objective To explore the impact of individualized exercise guidance during pregnancy on the mode of delivery in primiparas and its potential mechanisms.Methods A total of 160 primiparas who had regular prenatal check-ups and deliveries at Xindu District Central Hospital of Xingtai City,Hebei Province were recruited from December 2021 to September 2022.Those with pregnancy complications,comorbidities,or contraindications to exercise were excluded.The participants were randomly divided into an intervention group and a control group using a random number table.Both groups of pregnant women received routine obstetric care and health education,and the intervention group received individualized exercise programs formulated by professional teachers on this basis.The primary outcome was the mode of delivery.Results The cesarean section rate in the intervention group was 13.92％,compared to 34.18％ in the control group,with a statistically significant difference(x2=7.80,P＜0.05).The average weight gain during pregnancy was 11.71±2.69kg in the intervention group and 14.60±5.06kg in the control group.The incidence of excessive weight gain during pregnancy was 26.58％in the intervention group and 56.96％ in the control group,both showing statistically significant differences(x2=15.02,P＜0.05).A mediation effect model revealed that delivery intention mediated the impact of individualized exercise guidance on the mode of delivery(Zm=1.86,P＜0.05).Conclusion Individualized exercise guidance during pregnancy can not only reduce the rate of cesarean section,but also control the reasonable increase of pregnancy weight.Delivery intention may serve as a mediating factor in the effect of exercise intervention on reducing the cesarean section rate.
