The frequency of anemia, iron deficiency and iron body stores was assessed in 155 pregnant teenagers of low socioeconomic status in a prenatal care unit of a beneficent hospital in São Paulo, Brazil. By the criterion of the World Health Organization (Hb < 12 g/dL) 14.2% of the pregnant adolescents had anemia. The iron deficiency diagnostic by saturation of transferrin < 16% and zinc protoporphyrin concentration > 60 (mol/mol heme were 45.8 and 42.6%, respectively. The iron body store (serum ferritin < 12 micrograms/L) was depleted for 48.4% of adolescents. It is concluded that the iron nutritional status of these adolescents were characteristics of the pregravidic inadequate iron store. Despite low percentage of the anemia, the high frequency of iron deficiency and depleted iron stores suggest a practical procedure to detect iron deficiency and the use of iron supplementation in teenagers.
在巴西圣保罗一家慈善医院的产前护理单元，对155名社会经济地位低下的怀孕青少年的贫血、缺铁和铁储备情况进行了评估。按照世界卫生组织的标准（血红蛋白<12 g/dL），14.2%的怀孕青少年患有贫血。通过转铁蛋白饱和度<16%和锌原卟啉浓度>60（mol/mol血红素）诊断缺铁的比例分别为45.8%和42.6%。48.4%的青少年铁储备（血清铁蛋白<12微克/升）耗尽。得出的结论是，这些青少年的铁营养状况具有孕前铁储备不足的特征。尽管贫血比例较低，但缺铁和铁储备耗尽的高频率表明，有必要采取切实可行的程序来检测缺铁情况，并对青少年使用铁补充剂。
