目的:探讨孕期系统干预对提高自然分娩率的影响。方法:选取在本院进行常规孕期检查、健康指导的98例初产孕妇为对照组,同时选择84例孕妇在对照组的基础上进行超声检查,营养、运动指导以及健康咨询等系统干预,作为观察组;对比分析两组孕妇营养物质的摄取、体重情况、分娩方式及产程时间。结果:观察组孕妇蛋白质、维生素A、叶酸、钙、铁、锌摄入量及与中国营养学会每日膳食指南的人体每日摄取推荐量(RDA)之比显著高于对照组(均P<0.05),孕期体重指数增加值(5.0±1.5)显著低于对照组的6.3±1.3(P<0.05),自然分娩率明显高于对照组且产程缩短(均P<0.05)。结论:对孕妇进行营养、运动指导及健康咨询等系统干预,可提高孕妇营养吸收、自然分娩率,控制体重,缩短产程,降低剖宫产率。
Objective: To investigate the influence of systemic intervention during pregnancy on the rate of natural childbirth. Methods: Ninety-eight primiparous pregnant women who underwent routine pregnancy examination and health guidance were selected as the control group. At the same time, 84 pregnant women were selected to receive systematic interventions such as ultrasound examination, nutrition, exercise instruction and health counseling on the basis of the control group. Observation group; comparative analysis of two groups of pregnant women nutrient intake, body weight, delivery mode and delivery time. Results: The ratio of dietary protein, vitamin A, folic acid, calcium, iron and zinc in pregnant women in the observation group was significantly higher than that of the control group (P < 0.05). The increase of body mass index during pregnancy (5.0 ± 1.5) was significantly lower than that of the control group (6.3 ± 1.3) (P <0.05). The rate of spontaneous delivery was significantly higher than that of control group and the labor was shortened (all P <0.05). Conclusion: Systemic intervention such as nutrition, exercise instruction and health counseling for pregnant women can improve nutrition absorption, natural delivery rate, weight control, shorten labor process and reduce cesarean section rate.
