厌食、腹痛儿童血铅水平的检测及预防探讨

The examination and prevention of the blood lead level in anorexia or bellyache children

目的探讨铅污染对小儿消化系统的影响以及预防措施。方法采用BH2100原子吸收光谱仪对118例腹痛患儿和123例厌食症患儿及148例健康儿童（年龄：1～6岁）进行血铅检测。结果腹痛组患儿和厌食组患儿血铅水平均值均高于对照组,两者对比差异有显著性意义。腹痛组（u=26.4,P〈0.01）,厌食组（u=25.1,P〈0.01）。结论血铅水平增高对小儿消化系统有影响,可导致小儿不明原因的腹痛,厌食,食欲低下等消化道症状。提示临床对小儿不明原因的腹痛、厌食应考虑其血铅水平,以查明病因,及时治疗,从而提高儿童的生长发育水平。

Objective： To explore the effect of lead pollution on children＇s digestion system and to find the prevention measures.Methods： The blood lead levels of 118 bellyache children,123 anorexia children and 148 healthy children（aged 1～6） were examined by BH2100 atomic absorption spectrum instrument.Results：The mean blood lead levels in bellyache group and anorexia group were significantly higher than that in healthy group,（u =26.4,P〈0.01） in bellyache group and（u =25.1,P〈0.01）in anorexia group respectively.Conclusion： The blood lead level affected the children＇s digestion system,the heightened level may lead to digestion system disease such as unexplained bellyache and anorexia.Therefore,as for children with unexplained bellyache and anorexia,we should consider the blood lead levels of them,so as to find the origin,treat in time and to improve their growth and development levels.
