本文旨在评价妊娠期间日常饮食锌摄入和锌补充对血浆和红细胞锌浓度的影响。结果表明,在对照组和补锌组中,高饮食锌摄入的妊娠妇女在随机分组时和以后的测量中红细胞锌水平均比低饮食锌摄入的妊娠妇女高,但血浆锌水平没有差异。当按妊娠期间每日总锌摄入量的中位数值划分受试对象时,发现妊娠26周、32周和38周时,两组间的血浆锌水平有显著差异。但是,没有发现红细胞锌水平有这种差异。
This article aims to assess the effects of daily dietary zinc intake and zinc supplementation on plasma zinc and zinc levels during pregnancy. The results showed that in the control group and the zinc supplementation group, pregnant women with high dietary zinc intake had higher levels of zinc in erythrocytes than those in the pregnant women with low dietary zinc intake at randomization and later, but there was no difference in plasma zinc levels . When subjects divided their median daily zinc intake during pregnancy, they found significant differences in plasma zinc levels between the two groups at weeks 26, 32, and 38 of gestation. However, no differences were found in red cell zinc levels.
