摘要
本文对259名正常初孕妇女的营养性贫血状况进行了调查分析。于不同孕期取血测定血清铁蛋白,红细胞原卟啉,血红蛋白,血清叶酸及血清维生素B_(12)含量。结果发现,孕妇体内铁缺乏、叶酸及维生素B_(12)不足随孕周增加日趋明显,至孕后期血清铁蛋白<12μg/L者达72.0%;红细胞原卟啉>500μg/L(全血)者占25.9%;血清叶酸<3μg/L者占32.1%;血清维生素B_(12)<150μg/L者为25.6%。259名孕妇中89名患有贫血,总患病率为34.4%。对89名贫血孕妇按缺铁性、叶酸缺乏,及铁和叶酸双缺进行分类,以缺铁性贫血为主,为61例(68.5%),叶酸缺乏贫血22例(28.1%),双缺者3例(3.4%)。不同孕期贫血的分类结果表明,缺铁性贫血随孕周增加所占比例逐渐下降;而叶酸缺乏贫血所占比例随孕周增加逐渐增高。
Anemia were studied in 259 normal primigravidas with a mean age of 26.5 years. Serum ferritin(SF), erythrocyte protoporphyrin(EP), haemoglob-in(HB), serum folate and vitamin B12 were detected at the first,second and third trimesters of pregnancy. Three types of anemia i. e. iron deficiency anemia (IDA), folate deficiency anemia and both iron and folate deficiency anemia occurred in the subjects studied, with the incidence rates of 68.5%, 28.1% and 3.4%, respectively. It was demonstrated that the total incidence of these three types of anemia was 34.4%(89/259). The proportion of IDA among 89 pregnant women suffering from anemia was decreasing gradually with the course of gestation, whereas the percentage of folate deficiency anemia was rising with the duration of pregnancy.
