目前,瑞典妇女妊娠后半期常规补充铁剂,以保证孕期对铁需求增加的700mg。已知快速生长阶段对锌需求量很高,有报道先天畸形及出生时合并症与血浆低锌有关。血浆及红细胞叶酸浓度随妊娠而下降,但在瑞典临床上巨细胞贫血发生率低,作者研究这些指标在孕期会受到何种程度的影响,以判断孕期的营养供应。45名20—40岁妇女,于孕12、20、28、32、36周及产后2月采血、测定血浆铁蛋白、血浆和全血锌、红细胞锌以及血浆与红细胞叶酸盐含量。参检 Currently, Swedish women routinely supplement iron supplementation during the second trimester of pregnancy to ensure an increase of 700 mg of iron during pregnancy. Known rapid growth stage of zinc demand is high, there are reports of congenital malformations and complications at birth and low plasma zinc related. Plasma and erythrocyte folate concentrations decrease with pregnancy, but the incidence of Giant Cell Anemia in Swedish clinics is low, and the authors study the extent to which these indicators will be affected during pregnancy to determine the nutrient supply during pregnancy. Forty-five women aged 20-40 collected blood at 12, 20, 28, 32, 36 and 12 months after pregnancy. Plasma ferritin, plasma and whole blood zinc, erythrocyte zinc and plasma and erythrocyte folate were measured. Senate
