RESUMEN
Objective To analyze the relationship between anemia and blood levels of lead and trace elements in children,and to provide basis for the prevention and treatment of anemia.Methods 80 children with anemia(case group)and 90 health children (control group)were enrolled in the study.The blood levels of trace elements (iron,zinc,calcium,magnesium,copper)and lead were detected in all subjects,in order to analyze their correlations with anemia.Results Compared with control group,the blood levels of iron,zinc and magnesium in case group were significantly lower(P0.05).With the re-duction of iron,zinc and magnesium and the rise of calcium and lead,the severity of anemia increased significantly(P0.05).The blood level of iron was positive correlated with Hb,RBC and MCH (P<0.05).The blood level of zinc was positive correlated with Hb and MCH(P<0.05).The blood level of lead was negative correlated with Hb,MCV and MCH(P<0.05).Conclusion The blood level changes of trace elements and leas effect the severity of anemia in children.It is necessary to test the blood levels of trace elements and lead.
