作者对北京市宣武区妇幼保健院645名产前健康检查孕妇进行了缺铁性贫血的调查研究。对其中44名用24小时回顾法进行了膳食调查,发现铁摄取量超过供给标准。从645名各期孕妇血红蛋白含量、红细胞数及血球压积测定结果,发现孕妇贫血患病率随妊娠而有明显增加,末期最高。膳食中铁吸收利用不良可能是缺铁的主要原因。33例贫血孕妇每天补充元素铁平均12.4mg,维生素C66mg,1个月后血红蛋白水平明显升高,说明这些孕妇贫血原因主要是铁的不足所引起。对贫血孕妇补充铁剂是必要的,作者认为在摄入适当的维生素C时,每日给贫血孕妇补充元素铁10mg左右是适宜的。
The authors investigated 645 prenatal health examinations of pregnant women with iron deficiency anemia in the Xuanwu District Maternal and Child Health Hospital in Beijing. Forty-four of them conducted a 24-hour dietary review and found that iron intake exceeded supply standards. From 645 pregnant women with various stages of hemoglobin content, red blood cell count and hematocrit results showed that pregnant women with anemia prevalence increased significantly with pregnancy, the highest end. Absorption and utilization of iron in the diet may be the main reason for iron deficiency. 33 cases of anemia pregnant women daily supplementation of elemental iron average 12.4mg, vitamin C66mg, 1 month after hemoglobin levels were significantly increased, indicating that these pregnant women anemia is mainly caused by iron deficiency. Iron supplementation of anemia in pregnant women is necessary, the author believes that the intake of appropriate vitamin C, the daily supplement of iron to pregnant women about 10mg of iron is appropriate.
