Abstract

Background: Lead is considered a neurotoxic agent. We aimed to evaluate the blood lead level (BLL) in young population and determine probable risk factors of lead exposure in Iran.

Methods: In a cross-sectional study, a total of 100 children were entered and their BLLs were checked.

Results: In all, 25 and 8 patients had BLLs above 5 and 10 µg/dL, respectively. There was a significant univariate correlation between BLL and place of living, water pipe type, using dairy products, and stature in both cut-offs of 5 and 10 µg/dL. Binary regression analysis showed that pipe type was associated with high BLLs at cut-offs of 5 and 10 µg/dL, respectively. Also, there was an association between 50th percentile of stature for age and cut-off of 5 µg/dL.

Conclusions: Higher BLLs may be seen in short stature pediatric population. Polyvinyl chloride (PVC) and polypropylene water pipes may even cause more release of lead and result in higher absorption of this metal in the pediatric population.

德黑兰100名儿童高血铅水平的相关因素

背景:铅被认为是一种神经毒性物质。我们的目的是评估年轻人群的血铅水平(BLL)，并确定伊朗铅暴露的可能危险因素。方法:采用横断面研究方法，对100例儿童进行bll检查。结果:25例和8例患者的bll分别高于5和10µg/dL。在5µg/dL和10µg/dL的临界值范围内，BLL与居住地、水管类型、使用乳制品和身高之间存在显著的单变量相关性。二元回归分析显示，在5µg/dL和10µg/dL的临界值下，管型与高bll相关。此外，身高与年龄的第50百分位数与5 μ g/dL的临界值之间存在关联。结论:较高的bll可能出现在身材矮小的儿童人群中。聚氯乙烯(PVC)和聚丙烯水管甚至可能导致更多的铅释放，并导致儿童对这种金属的更高吸收。
