孕期营养素摄入量对胎儿宫内发育的影响

Effects of nutrient intake in the gestation on fetus intrauterine growth retardance

目的 :研究不同孕期营养素摄入量对胎儿宫内发育的影响。 方法 :2 0 0例妊娠妇女分为 10～ 2 0周、2 1～ 30周及 31周以上 3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RDA(推荐的每日膳食中营养素供给量 )间胎儿宫内发育迟缓的发生率。 结果 :第 1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 ,但差异不显著 (P>0 .0 5 ) ;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 ,差异显著 (P<0 .0 5 ) ;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 ,差异亦不显著(P >0 .0 5 )。 结论

Objective: To study the effect of nutrient intake in different periods of gestation on fetus intrauterine growth. Methods: 200 cases of pregnant women were divided into three groups: (1) 10～20 weeks; (2) 21～30 weeks; (3) upwards of 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 and group 3: Comparison to cases with <90% RDA, but no significant difference (P>0.05); Group 2: Comparison to cases with <90% RDA or >110% RDA, the incidence rate of fetus intrauterine growth retardance was higher than in pregnant women with 110%～90% RDA (P<0.05). Conclusion: It is important of optimal nutrient intake to reduce the incidence rate of fetus intrauterine growth retardance.
