目的:了解百色市0～6岁儿童血铅水平及铅中毒流行情况,为儿童的铅防治提供科学指导。方法:自2008年1月～2010年12月对百色市妇幼保健院儿童保健科及百色市城区幼儿园1 544例0～6岁儿童采用原子吸收光谱仪进行末梢血铅测定,观察儿童血铅水平及铅中毒检出率,同时对不同性别及不同年龄组儿童的血铅水平进行比较。结果:1 544例儿童末梢血铅浓度呈正态分布,血铅水平0μg/L～304μg/L,平均(59.3±23.5)μg/L;其中1 433例儿童血铅在正常范围内,其余111例血铅均超过正常范围。男童组与女童组血铅水平无统计学差异,983例男童中,62例铅中毒,561例女童中,49例铅中毒。0～1岁,1～2岁,2～3岁,血铅水平及铅中毒检出率呈逐渐增高趋势,3～4岁,4～5岁血铅水平有所下降,5～6岁血铅水平又再次回升。结论:百色市0～6岁儿童铅中毒发生率较高,应引起儿童家长、老师及社区的高度重视,并结合多方面的力量,尽量避免铅中毒的各种危险因素,为儿童铅中毒的防治提供保障,促进儿童健康成长。
Objective: To understand the prevalence of lead levels and lead poisoning in children aged 0 ~ 6 years in Baise city and to provide scientific guidance for the prevention and treatment of lead in children. Methods: From January 2008 to December 2010, 1 544 children aged 0-6 years in the Children’s Health Care Center of Baise MCH and Baise City Kindergarten children were tested for their blood lead levels by atomic absorption spectroscopy. Blood lead level and Lead poisoning detection rate, at the same time, different gender and age groups of children blood lead levels were compared. Results: The blood lead levels were normal in 1 544 children with blood lead level of 0μg / L ~ 304μg / L, with an average of (59.3 ± 23.5) μg / L; of which 1 433 children had normal blood lead levels and 111 Cases of blood lead exceeded the normal range. There were no significant differences in blood lead levels between boys and girls, 62 of 983 boys were lead poisoning and 56 of 561 girls were lead poisoning. 0 to 1 year old, 1 to 2 years old, 2 to 3 years old, blood lead levels and lead poisoning detection rate showed a gradual upward trend, 3 to 4 years old, 4 to 5 years of blood lead levels have declined, 5 to 6 years of blood Lead levels rise again. Conclusion: The incidence of lead poisoning in children aged 0 ~ 6 years in Baise City is relatively high, which should be paid great attention to by parents, teachers and community. Combined with various forces, various risk factors of lead poisoning should be avoided as much as possible. Prevention provides protection and promotes the healthy growth of children.
