【摘要】 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。更多还原

【Abstract】 The objects of the present investigation are to ascertain the prevalence of iron deficiency anemia among pregnant women in Beijing, the adequacy of their diets and their response to oral iron supplementation.Six hundred and fourty five urban pregnant women attending the outpatient antenatal clinic of a maternal and child health station in Beijing served as the experimental subjects. Besides the antenatal examination, all of the subjects also received hemoglobin, red blood cell count and hemato-crit determinations. It was found that the prevalence of iron deficiency anemia, by WHO standard (Hb<11g/dl), amounts to 12.6%.The 24 hr dietary survey in 44 pregnant women were carried out by recall of household food consumption. It was found that their diets were adequate in energy, thiamine and niacin, but vitamin A and riboflavin were likely to be inadequate. The intakes of iron from the diet were higher than the RDA, but these women consumed only little animal foods containing heme iron, this may be the cause of anemia.The iron fortified glucose supplementation was given orally to 33 anemic pregnant women. Each received elementary iron 12.4 mg and ascorbic acid 66 mg daily for one month. At the end of the experiment, the mean Hb and Hct values of these subjects were all significantly higher than that at the begining of the trial. The mean increases of the Hb and Hct both are highly significant. These findings suggest that the deficiency of iron is an important etiological factor contributing to the pathogensis of anemia in these pregnant women.更多还原
