孕妇与非孕妇蛋白质和钙铁锌铜营养状况的比较

COMPARISION OF NUTRITIONAL STATUS OF PROTEIN AND MINERALS IN PREGNANT WITH NON PREGNANT WOMEN

比较了３２名非孕妇女和１０８名孕妇的膳食状况和２７名非孕妇女与４６名孕妇发样中钙、铁、锌、铜及尿样中氮、钙、锌含量。结果表明这些元素的摄入量和排出量在孕中期和孕后期没有显著差别。孕妇尿中氮和锌的排出显著高于非孕妇女；孕妇钙摄入量显著高于非孕妇，但尿钙和发钙没有差别，表明孕中期和孕后期钙的摄入并不充分；孕后期有２４％的人血红蛋白低于１００ｇ／Ｌ，孕妇和非孕妇中有５０％的人铜摄入不足，约２０％的人发铜低于０．１２５ｍｍｏｌ／ｋｇ。

A comparision study based on a dietary survey on 180 pregnant with 32 non pregnant women and measurement of nitrogen and minerals in hair or urine of 46 pregnant with 27 non pregnant women was carried out. The results showed that there was no significant difference of N,Ca,Fe,Zn and Cu between the 2nd and the 3rd trimesters in intake and in levels in hair or urine. Levels of urine N and Zn were higher in pregnant than non pregnant women. Levels of hair Ca and urine Ca in pregnant were not different from non pregnant women though Ca intake was markedly higher in pregnant women,which indicated the intake of Ca in pregnant women was not sufficient.Hemoglobin level in 24% of pregnant women at the 3rd trimester was lower than 100g/L.About half of both pregnant and non pregnant women were short of copper intake and about 20% of them had their hair copper lower than 0.125 mmol/kg.
