【摘要】 目的:研究营养指导对孕妇体重增长及妊娠结局的影响。方法:选择2012年7月—2012年8月在卫生部北京医院产科常规查体的164例孕妇为研究对象,于孕中期建档日开始进行个体化饮食指导,于孕22~24w糖筛后对妊娠糖尿病(GDM)孕妇进行饮食控制并跟踪整个孕期。分别记录血糖正常组和GDM组孕妇孕24w体重及产前体重,记录新生儿体重、身长、胎盘重、巨大儿及剖宫产人数等指标。结果:孕24w体重增长值:GDM组为7.53±2.80kg、血糖正常组为6.66±3.68kg(P=0.35);产前体重增长值:GDM组为15.25±3.54kg;血糖正常组为17.21±4.85kg(P=0.12);巨大儿发生率:GDM组为25%、血糖正常组为6.4%(P=0.04);剖宫产率:GDM组为68.8%、血糖正常组为35%(P=0.01)。结论:个体化饮食指导有利于孕妇的合理体重增长,但是并未显著改变巨大儿发生率的增加,建议针对高危孕妇进行早期营养干预。更多还原

【Abstract】 [Objective] To study the effect of nutrition guidance on pregnant women’s body weight increase and pregnancy outcome.[Method] We chose 164 pregnant women who did routine inspection in Obstetrical Department of Beijing Hospital from July 2012 to August2012,tracked the whole pregnancy and gave the individualized dietary guidance. Controlled diet was given to GDM. We recorded two teams’ pregnancy body weight at 24 w,prenatal body weight,fetal birth weight and length,weight of placenta,Macrosomia and the number of cesarean section,etc. [Result] The gestational weight gain at 24w: GDM was 7. 53 ± 2. 80 kg,NBG was 6. 66 ± 3. 68kg( P = 0. 35). Prenatal body weight increase: GDM was 15. 25 ± 3. 54 kg,NBG was 17. 21 ± 4. 85kg( P = 0. 12). The incidence of macrosomia: GDM was25%,NBG was 6. 4%( P = 0. 04). The rate of cesarean section: GDM was 68. 8%,NBG was 35%( P = 0. 01). [Conclusion] Individualized dietary guidance was beneficial to reasonable body weight increase of pregnant women,but did not change significantly the incidence of macrosomia,so the nutritional intervention for high-risk pregnant women should be conducted.更多还原
