摘要
目的探讨微量元素含量对新生儿出生状况的影响。方法用日本产原子吸收光度仪(J800)测定816名孕晚期孕妇头发中Zn、Cu、Fe三种微量元素的含量,并对所有新生儿进行体重、身长的测量及Apgar评分。结果孕晚期孕妇微量元素缺乏者占59.80%,三种元素均缺乏者占12.75%。母三种微量元素均正常者其新生儿出生时的体重高于母三种微量元素均缺乏者或低锌低铁者其新生儿出生时的体重,与后两者间有显著性差异(u=2.62,P<0.01,u=2.17,0.01<P<0.05)。一种或一种以上微量元素缺乏者其新生儿出生时的Apgar评分中,<8分的人数构成高于三种微量元素均正常者的新生儿人数,两者间差异有意义(χ2=4.50,P<0.05)。结论孕晚期孕妇微量元素含量对新生儿出生状况有一定影响。孕妇在妊娠期间应加强营养,增加体内各种必需微量元素的含量和活性,保证母婴健康。
Objective To explore the influence of trace elements level of the pregnant women on their newborns' birth status. Methods The content of Zn, Fe, and Cu in hair of 816 pregnant women were determined by atom absorbing spectrum, and the body weight and height of their newborn babies were measured and Apgar Grade was evaluated. Results The incidence of one or more trace elements deficiency accounted for 59.80%, and the incidence of three trace elements deficiency was 12.75%. In the mothers whose had these three trace elements were in the normal range, their newborns weighted significantly more than those newborns whose mothers were in deficiency of Zn+Fe ,or Zn+Fe+Cu (u=2.62, P<0.01, u=2.17, 0.01< P<0.05). In those newborns whose mothers were deficient one or more trace elements, the number of less than 8 in Apgar score was significantly higher than those newborns whose mothers were adequate of these three trace elements (χ 2=4.50, P<0.05). Conclusions Deficiency of trace elements of pregnant women during the third trimester might affect their newborns' birth status. Pregnant women should improve food structures to enrich nutrition including the content of trace elements so that to provide mother and neonate healthy.
