摘要
为探讨儿童行为异常与食品中铅摄入的关系,在南京市选取404名儿童,用询问法调查其3d的膳食摄取情况,了解儿童食物、营养素及铅的摄入量,并用原子吸收分光光度法测定血铅水平,用原子吸收分光光度法进行食物中铅含量的测定,用CBCL行为量表分析儿童行为。在404名调查对象中,行为异常的学生有44例,占总人数10.9%,男生行为异常发生率明显高于女生。行为异常组儿童的血铅水平及铅摄取量明显高于行为正常组,且蔬菜、水果、畜肉及其它(主要是膨化食品)类食品摄取量显著多于行为正常组,其脂肪摄取量相对较高,而维生素C摄取量则相对较低,在农贸市场或个体摊点购零食人数显著多于在商场、超市者。食品中铅摄入量过高与儿童血铅水平升高、行为异常有关。
To study the relationship between children＇s behavior disorders and the intake of lead, the lead concentration in foods of 404 children selected in Nanjing was measured with atomic absorption spectrum （AAS）. Their food intake of 3successive days was investigated, thus foods, nutrients and lead intake were learned. Their blood lead level was also determined by AAS. CBCL was used to evaluate the children＇s behavior status. There were 44 children with behavior disorder （ 10.9% ） with prevalence in boys higher than that in girls. The blood lead level and lead intake from foods were obviously higher in children with behavior disorder. They took more fruits, vegetables and cakes, inflated foods than the normal children. Their fat intake was relatively higher and vitamin C intake was relatively lower. They bought snacks from farm product markets or street pedlars more often. The risk factors for children＇s behavior disorders were the intake of roots and meats, the improper purchasing place of snacks and the nail oil used by mothers, while the zinc intake was a protective factor. It was concluded that excessive intake of lead may be related to the high level of blood lead and behavior disorder of children.
