目的:探讨新疆克拉玛依市2～7岁儿童的血铅水平现状及其影响因素。方法:分层随机抽取782例2～7岁儿童静脉血进行血铅测定,同时进行身高、体重、血红蛋白值测定及统一问卷调查。结果:782例中血铅<100/μg/L有439例,≥100/μg/L有343例,其血铅水平分别为63.10±21.52/μg/L、137.29±36.95/μg/L。5岁～和6～7岁组血铅水平较2岁～、3岁～和4岁～组明显增高,具有统计学差异(F值=9.298,P<0.05)。不同性别间血铅水平无显著差异(P>0.05)。相关因素分析表明高血铅组与低血铅组在计数资料比较无明显差异。结论:目前本地区儿童铅中毒的流行率为43.9％,儿童高血铅与大气铅污染有密切关系。降低环境铅污染及提高儿童生活小环境对于早期干预小儿铅中毒具有重要意义。
Objective: To explore the status of blood lead levels and its influencing factors in children aged 2 ~ 7 years in Karamay, Xinjiang. Methods: A total of 782 children aged 2 to 7 years were randomly divided into two groups. Blood samples were collected for blood lead determination. Height, weight and hemoglobin were measured at the same time. Results: There were 439 cases of blood lead <100 / μg / L in 782 cases, 343 cases of ≥100 / μg / L, the blood lead levels were 63.10 ± 21.52 / μg / L and 137.29 ± 36.95 / μg / L respectively. The levels of blood lead of 5 years old ~ 6 ~ 7 years old group were significantly higher than those of 2 years old ~ 3 years old and 4 years old group (F = 9.298, P <0.05). There was no significant difference in blood lead levels between different sexes (P> 0.05). Correlation analysis showed that high blood lead group and low blood lead group in the count data there was no significant difference. Conclusion: At present, the prevalence of lead poisoning in children in this area is 43.9%. There is a close relationship between high blood lead level in children and lead pollution in the atmosphere. Reduce environmental lead pollution and improve children’s living environment for early intervention in children with lead poisoning is of great significance.
