目的:探讨孕期个体化热能供给对巨大儿发生的影响作用。方法:选取2003年7月～2006年6月在该院进行常规产前检查并住院分娩的单胎初产妇1003例作为研究组,同时选取同期1258例作为对照组,根据孕前体重指数(BMI)分组,分别为正常体重组(BMI18.5～22.9)、超重组(BMI23～24.9)、肥胖组(BMI≥25),各组又分为研究组、对照组,孕妇的年龄及BMI差异均无统计学意义。根据孕前BMI,应用PNM1.0孕期营养个体化专家指导系统制定个体化热能供给方案,对照组孕妇给予一般的饮食健康教育。动态监测孕期体重、孕期体重指数增加及新生儿出生体重。结果:3组中的研究组与对照组巨大儿发生均有统计学差异(P<0.05)。结论:孕期进行个体化热能供给有利于降低巨大儿发生率。
Objective: To investigate the effect of individualized heat supply during pregnancy on the macrosomia in children. Methods: A total of 1003 singleton primipara from July 2003 to June 2006 in our hospital were selected as the study group, and 1258 newborns in the same period were selected as the control group. According to the body mass index (BMI) before pregnancy, (BMI18.5 ~ 22.9), overweight group (BMI23 ~ 24.9), and obesity group (BMI≥25). There were also no differences in the age and BMI between study group, control group and pregnant women Statistical significance. According to pre-pregnancy BMI, application PNM1.0 individual nutrition during pregnancy guidance system to develop personalized energy supply program, pregnant women in the control group to give general diet health education. Dynamic monitoring of pregnancy weight, body mass index during pregnancy and newborn birth weight. Results: There was a significant difference in the incidence of macrosomia between study group and control group (P <0.05). Conclusion: Individualized heat supply during pregnancy is helpful to reduce the incidence of macrosomia in children.
