孕期营养素摄入量对胎儿宫内发育的影响

Effects of nutrientin take in the gestation on fetus intrauterine growth retardance

目的研究不同孕期营养素摄入量对宫内胎儿发育的影响。方法239例妊娠妇女分为10～20周、21～30周及31周以上三组，根据营养素摄入量，用常规方法确定不同孕期胎儿宫内发育迟缓，比较不同孕期及不同营养素供给量（RDA）间胎儿宫内发育迟缓的发生率。结果第1、2、3组：与〈90％RDA及〉110％RDA者比较，90％～110％RDA者的胎儿宫内发育迟缓发生率较低，但差异无统计学意义（P〉0．05）；第2组：与〈90％RDA及〉110％RDA者比较，90％～110％RDA者的胎儿宫内发育迟缓发生率较低，差异有统计学意义（P〈0．05）；第3组：与〈90％RDA及〉110％RDA者比较，90％～110％RDA者的胎儿宫内发育迟缓发生率较低，差异亦无统计学意义（P〉0．05）。结论合理的营养素摄入量对于降低胎儿宫内发育迟缓的发生率具有重要意义。

Objective To study the effect of nutrientin take in different periods of gestation on fetus intrauterine growth. Methods 239 cases of pregnant women were divided into three groups： （1）10 -20 weeks;（2） 21 -30 weeks ;（3） 〉 31 weeks. Nutrient intake was calculated by computer nutrition system. Fetus intrauterine growth retardance in different periods of gestation was estimated by routine methods. Comparing the incidence rate of fetus intrauterine growth retardance between different periods of gestation and different nutrient intake. Results Group 1, group2 and group3 ： Comparison to cases with 〈 90% RDA or 〉 110% RDA, the incidence rate of fetus intrauterine growth retardance was higher than in pregnant women with 90% - 110% RDA （ P 〈 0.05 ）. Conclusion It is important of optimal nutrient intake to reduce the incidence rate of fetus intrauterine growth retardance.
