对一青年男性人群的缺铁性贫血和核黄素营养状况的关系进行了观察。发现：其核黄素缺乏率为４２．９％（３０／７０），缺铁性贫血率为３７．５％（２７／７２），游离原卟啉（ＦＥＰ）异常率为１１．０％（８／７３）。核黄素缺乏者平均血红蛋白（Ｈｂ）浓度低于核黄素正常者，缺铁性贫血率（５０％）显著高于核黄素正常者（２５．０％，Ｐ＜０．０５），而两者的ＦＥＰ异常率无差别。对全血谷胱甘肽还原酶活性系数（ＢＧＲＡＣ）与Ｈｂ、ＦＥＰ和红细胞压积（ＨＣＴ）做相关回归分析，发现ＢＧＲＡＣ与Ｈｂ、ＨＣＴ呈显著负相关（Ｐ＜０．０５），而与ＦＥＰ无显著相关关系。结果提示：核黄素缺乏与缺铁性贫血有关系，而与反映铁缺乏的早期指标ＦＥＰ无关
The relationship between iron deficiency anemia and riboflavin nutrition status in a young male population was observed. The results showed that the rate of riboflavin deficiency was 42.9% (30/70), the rate of iron deficiency anemia was 37.5% (27/72) and the rate of free protoporphyrin (FEP) was 11.0% ( 8/73). The average hemoglobin (Hb) concentration of riboflavin deficiency was lower than that of normal riboflavin, and the rate of iron deficiency anemia (50%) was significantly higher than that of normal riboflavin (25.0%, P <0.05) No difference between the two FEP anomalies. Correlation analysis between BGRAC, Hb, FEP and hematocrit (HCT) showed that there was a significant negative correlation between BGRAC and Hb, HCT (P <0.05) FEP no significant correlation. The results suggest that riboflavin deficiency is associated with iron deficiency anemia and not to FEP, an early indicator of iron deficiency
