【摘要】 目的探讨孕期热量个体化供给与控制孕期母婴体重、降低孕期并发症,改善妊娠结局的关系。方法选取2009年1-12月在济南市妇幼保健院进行常规产前检查,有控制体重意愿并在该院分娩的单胎初产妇1010人作为研究组,同时选取同期无控制体重意愿的1270人作为对照组,根据孕前或孕12周前体重指数(BMI)不同分为正常体重组、超重组、肥胖组3组。研究组中3组热量供给分别为36～40、33～35.9、30～32.9kcal·kg/日,同时利用孕期营养个体化专家指导系统PNM1.0,适时调整热量及各种营养素供给。对照组热量供给不限制。指导孕妇进行轻体力劳动。结果 3组孕妇的孕期体重增加、BMI增加及巨大儿、妊娠期糖尿病(GDM)、相对头盆不称及医学指征剖宫产率,研究组均低于对照组,差异有统计学意义(P<0.01)。结论对孕前不同BMI孕妇给予不同的热量供给,对控制孕期增重、降低巨大儿及GDM的发生率临床效果满意,进而降低难产及剖宫产率。更多还原

【Abstract】 Objective To study the relationship between individual pregnancy energy supply,weight control during pregnancy,decreasing pregnancy complication and improve pregnancy ending.Methods 1010 women were selected as research group,and they had their prenatal examination,weight control wish and puerperal primipara at Jinan Women and Children Healthy Hospital from January 2009 to December 2009,at the same time,1270 women without weight control wish were selected as control group.According to the pregestational BMI,both group’s pregnant women were divided into three groups of normal weight,overweight and obesities.Three research groups were supplied different energy of 36～40,33～35.9,30～32.9 kcal·kg/day,and expert guidance systems PNM1.0 was used for adjusting heat and nutrients supply,but the control group without restriction.Results Compared to control group,research group have lower values of pregnancy weight increase,BMI increase,great children,gestational diabetes mellitus(GDM) ,relative cephalopelvic disproportion and medical indications(P<0.01) .Conclusions Providing different energy supply project for different pregestational BMI can reduce dystocia and cesarean section rate,this had obtained satisfactory clinical results in pregnancy weight control,reduce huge children and the rate of GDM.更多还原
