The frequency of anemia and iron nutrition deficiency was assessed in 342 low socioeconomic level pregnant teenagers at entry to prenatal care in 5 outpatient clinics from a South Orient area of Santiago Chile. According to the Center for Disease Control Criteria, 1.2% of women had iron deficiency anemia. Iron stores were insufficient (defined as a serum ferritin lower than 20 g/L) in 55% for women and depleted (serum ferritin lower than 10 g/L) in 21%. Women with more than 14 weeks of gestation had lower packed red cell volumes, hemoglobin, mean corpuscular volumes and ferritin levels than women with less than 14 of gestation. It is concluded that the prevalence of iron deficiency anemia is lower than that predicted for a highly vulnerable group but the high frequency of low iron stores should encourage the use of iron supplementation in these teenagers.
对来自智利圣地亚哥东南部地区5家门诊诊所的342名社会经济水平较低的怀孕青少年进行产前检查时，评估了贫血和铁营养缺乏的发生率。根据疾病控制中心的标准，1.2%的女性患有缺铁性贫血。55%的女性铁储备不足（定义为血清铁蛋白低于20μg/L），21%的女性铁储备耗竭（血清铁蛋白低于10μg/L）。妊娠超过14周的女性比妊娠少于14周的女性红细胞压积、血红蛋白、平均红细胞体积和铁蛋白水平更低。结论是，缺铁性贫血的患病率低于对高度脆弱群体的预测，但高铁储备不足的发生率应促使对这些青少年使用铁补充剂。
