目的:分析银川市儿童血铅水平变化及相关因素。方法:对2004年该市0～6岁的1158名儿童,2005年1414名儿童,2006年1204名儿童,采用国际领先的BH2100B型钨舟原子吸收光谱仪进行血铅分析,并做相关因素问卷调查。结果:①2004年血铅水平≥100μg/L者占15.2%,2005年血铅水平≥100μg/L者占10.3%,2006年血铅水平≥100μg/L者占9.3%。全托儿童血铅水平高于散居儿童,差异显著(P<0.01)。大年龄段儿童血铅水平高于小年龄段儿童,差异有显著性(P<0.01);②线性回归分析显示,儿童血铅水平与下列6项因素有关:母亲文化程度,父母从事与铅有关的行业,房屋建造年代,经常服用中草药,经常吃膨化食品,经常服用钙铁锌剂。结论:儿童血铅水平与某些生活行为有密切关系。
Objective: To analyze the changes of blood lead levels and related factors in Yinchuan children. Methods: A total of 1158 children aged 0 ~ 6 years, 1,414 children in 2005 and 1204 children in 2006 were enrolled in this study. Blood lead was analyzed by BH2100B Tungsten-boat Atomic Absorption Spectrometer . Results: ① In 2004, the blood lead level ≥100μg / L accounted for 15.2%. In 2005, the blood lead level ≥100μg / L accounted for 10.3%. In 2006, the blood lead level ≥100μg / L accounted for 9.3%. The level of blood lead in full-time care children was higher than that in scattered children, with significant difference (P <0.01). The level of blood lead was higher in older children than in children of younger ages (P <0.01). (2) The linear regression analysis showed that the level of blood lead in children was related to the following six factors: the level of mother’s education, the parents’ The industry, housing construction, often take herbal medicine, often eat puffed food, often taking calcium iron zinc. Conclusion: The level of blood lead in children is closely related to some life behaviors.
