目的:对28例儿童血铅水平监测结果分析,探讨其危险因素。方法:采用血铅分析仪监测28例儿童血铅水平,探讨儿童年龄、性别的血铅水平差异性,探讨其危险因素。结果:28例儿童平均血铅水平为、铅中毒发生率为;14例女性儿童平均血铅水平为,14例男性儿童平均血铅水平为;两组数据无统计学差异(P>0.05);大于6岁的儿童平均血铅水平为,小于6岁的儿童平均血铅水平为;两组数据无统计学差异(P<0.05);大气铅污染、室内铅尘、装饰材料、铅污染水源、玩具学习用品及铅污染食品均可提高儿童血铅水平,增加铅中毒的风险,与儿童血铅水平呈正相关(r=0.36、4.59、3.68、0.41、0.32、0.36,P<0.05)。结论:儿童血铅水平与年龄呈正相关性,导致儿童血铅水平提高的危险因素具有多样性,可通过行为干预儿童的日常行为,提高儿童的饮食卫生水平及优化儿童的生活学习环境,有利于降低铅中毒的风险。
Objective: To analyze the blood lead levels in 28 children and explore the risk factors. Methods: The level of blood lead in 28 children was monitored by blood lead analyzer. The differences of blood lead level in children age and sex were investigated to explore the risk factors. Results: The average blood lead level was 28 cases. The average blood lead level of 14 female children was 14 and the average blood lead level was 14 male children. There was no significant difference between the two groups (P> 0.05). The mean level of blood lead in children above 6 years old was mean blood lead level in children younger than 6 years of age; there was no significant difference between the two groups (P <0.05); lead pollution in the atmosphere, indoor lead dust, decorative materials, lead contaminated water, Toy learning products and lead contaminated food can increase children’s blood lead levels, increasing the risk of lead poisoning, and children’s blood lead levels were positively correlated (r = 0.36,4.59,3.68,0.41,0.32,0.36, P <0.05). Conclusion: There is a positive correlation between the level of blood lead and age in children, which leads to the diversity of the risk factors of blood lead level in children, which can intervene the daily behavior of children through behavior, improve children’s food hygiene level and optimize children’s living environment, Reduce the risk of lead poisoning.
