北京地区妊娠期妇女补锌的探讨

The women from Beigjing area during pregnancy need zinc supplement

观察452名正常初产孕妇的血清锌水平及79名农村孕妇随机分为二组,实验组进行孕期锌干预实验.结果表明,北京市孕妇膳食锌摄入普遍较低,在孕期全程补锌10mg/d仍不能阻止血清锌的下降,但幅度减小.实验组新生儿脐血清锌升高,其身长明显高于未补锌组,同时未见中枢神经系统畸形,对锌剂无不良反应.我们建议,在我国孕妇锌营养状况明显缺乏情况下,锌摄入量需进一步提高,所以常规补锌10mg/d非常必要.

In this article, the serum level of zinc of 452 normal primiparae have been tested and interfering test of the zinc have been conducted on 79 pregnant women in the rural areas who have been divided into two groups randomly. The result shows that the intakes of zinc from daily diet of the pregnant women in Beijing are relatively low and this is a commonly seen situation. l0mg of zinc supplemented per day during whole period of pregnancy can not prevent the decreasing of the serum zinc, but the range of decreasing has been reduced. The serum levels of zinc in the umbilical blood of the newborns supplemented with zinc have been increased and the heights of these newborns is apparently longer than the ones not being supplemented with zinc. No nerurocanal deformity has been found and the pregnant women have showed no side reaction to the supplement of zinc. Since apparently the intakes of zinc of the pregnant women in our country are not enough and the amount of zinc intakes need be increased urgently, so supplementing lOmg zinc per day regularly is really necessary.
