孕期个性化膳食营养指导对孕妇肠道菌群及妊娠结局的影响

Effects of personalized dietary nutrition guidance during pregnancy on intestinal flora and pregnancy outcome

目的探讨孕期个性化膳食营养指导对孕妇肠道菌群及妊娠结局的影响。方法选取359例孕妇,根据随机数字表法分为对照组(179例)与观察组(180例)。对照组采用常规饮食指导,观察组采用个性化膳食营养指导,比较两组孕妇肠道菌群及妊娠结局。结果产前,观察组的双歧杆菌、乳酸杆菌含量比对照组高,拟杆菌、肠杆菌、肠球菌含量比对照组低(P<0.05)。观察组孕妇剖宫产率10.00%、产后出血率0.56%均明显低于对照组的23.46%、4.47%,观察组低体重儿发生率0%明显低于对照组的3.35%(P<0.05)。结论孕妇落实孕期个性化膳食营养指导可促进有益菌增长,调节肠道菌群平衡,利于孕妇自然分娩,减少产后出血率,预防低体重儿,保护母婴健康,值得临床推广。

Objective To investigate the effects of personalized dietary nutrition guidance on intestinal flora and pregnancy outcome.Methods 359 pregnant women were selected and divided into control group(179 cases)and observation group(180 cases)according to random number table method.The control group was given conventional dietary guidance,and the observation group was given personalized dietary nutrition guidance.The intestinal flora and pregnancy outcome of the two groups were compared.Results Before delivery,the contents of bifidobacterium and Lactobacillus in observation group were higher than those in control group,and the contents of Bacteroides,enterobacter and enterococcus were lower than those in control group(P<0.05).The cesarean section rate of 10.00%and postpartum hemorrhage rate of 0.56%in the observation group were significantly lower than those in the control group(23.46%and 4.47%),and the incidence of low birth weight infants in the observation group was 0%significantly lower than that in the control group(3.35%)(P<0.05).Conclusion The implementation of personalized dietary nutrition guidance during pregnancy can promote the growth of beneficial bacteria,regulate the balance of intestinal flora,facilitate the natural delivery of pregnant women,reduce postpartum bleeding rate,prevent low birth weight infants,and protect maternal and child health,which is worthy of clinical promotion.
