Effects of nutritional intervention and weight management during pregnancy on pregnancy outcome
孕期营养干预及体重管理对妊娠结局的影响

摘要

目的 研究孕期营养干预及体重管理对妊娠结局的影响。方法 将我院在2021.1月-2022.1月收治的640例孕妇作为研究对象，采用随机分组法分成两组，即对照组、研究组（n＝320），前者予以常规孕期指导干预，后者予以孕期营养干预及体重管理，对两组干预后的妊娠结局展开观察。结果 在孕早期、孕12周、孕20周BMI值比较上，两组无显著差异，P＞0.05；孕28周、孕36周、分娩时BMI两组比较，研究组BMI值要低于对照组，P＜0.05；两组妊娠结局比较，研究组的妊娠期高血压、妊娠期高血糖、剖宫产、产后出血发生率均显著低于对照组，P＜0.05；新生儿分娩情况对比，研究组新生儿情况优于对照组，P＜0.05。结论 孕妇接受孕期营养干预及体重管理，可降低出现不良分娩结局的概率，值得运用。

Abstract

Objective To study the effect of nutritional intervention on pregnancy weight.
Methods 64 pregnant women treated in our hospital from January 2021 to January 2022 were randomly divided into two groups: control group and study group (n = 32). The former was given routine pregnancy guidance intervention, and the latter was given pregnancy nutrition intervention and weight management. The pregnancy outcomes of the two groups were observed after intervention.
Results there was no significant difference in BMI between the two groups in early pregnancy, 12 weeks and 20 weeks of pregnancy (P > 0.05); The BMI of the study group was lower than that of the control group (P < 0.05); The incidence of pregnancy induced hypertension, pregnancy induced hyperglycemia, cesarean section and postpartum hemorrhage in the study group were significantly lower than those in the control group (P < 0.05); Compared with the delivery of newborns, the situation of newborns in the study group was better than that in the control group (P < 0.05).
Conclusion   pregnant women receiving nutritional intervention and weight management during pregnancy can reduce the probability of adverse delivery outcomes, which is worthy of application.
