番禺区0～6岁儿童血红蛋白与血铅水平相关性研究

目的 探讨番禺区0～6岁儿童血红蛋白（Hb）与血铅的相关性.方法 选择1 407例健康儿童,采用雅培CD1800三分类血球仪及原子吸收分光光度计检测其RBC、Hb、血细胞比容（HCT）.根据是否存在铅中毒,将上述儿童分为铅中毒组、非铅中毒组.结果 铅中毒组与非铅中毒组儿童RBC、HCT的差异无统计学意义（P〉0.05）,而两组儿童Hb间的差异有统计学意义（P〈0.05）.不同年龄儿童Hb浓度与血铅浓度呈正相关（r=-0.061,P〈0.05）.结论 番禺区0～6岁儿童Hb与血铅水平存在相关性,铅中毒儿童比正常儿童更容易诱发贫血症状.

A correlation research on hemoglobin and blood lead levels of 0-6 aged children in Panyu district

Objective To explore the correlation of hemoglobin（Hb） and blood lead of 0-6 aged children in Panyu district. Methods 1 407 healthy children were selected. Their blood RBC, Hb and hematoerit （HCT） were detected by Abbott CD1800 three categories blood analyzer and atomic absorption spectrophotometer. They were divided into lead poisoning group and non-lead poisoning group according to weather lead poisoning presence. Results Difference of RBC, HCT of children in lead poisoning group and non-lead poisoning group showed no statistically significant differences（P〈0.05） while the difference of their Hb had statistically significant differences（P〈0.05）. Hb concentration of children of different ages correlated with blood lead concentrations positively（r=-0. 061 ,P〈0.05）. Conclusion In 0-6 aged children, Hb correlated with blood lead levels in Panyu,and symptoms of anemia is more likely to occur in children with lead poisoning than in healthy ones.
