目的:探讨儿童睡眠异常与血铅水平变化的关系。方法:采用病例对照研究,以确诊为睡眠异常的患儿53例为实验组,以正常健康体检儿童32例为对照组,分析比较两组儿童血铅暴露水平。结果:实验组儿童血铅值为(0.68±0.27)μmol/L,对照组为(0.51±0.18)μmol/L,(P<0.05);实验组儿童血铅水平异常的发生率为75.47%;对照组为21.88%(P<0.01)。结论:儿童睡眠异常可能与血铅水平增高有关。
Objective: To investigate the relationship between abnormal sleep and blood lead levels in children. Methods: A case-control study was conducted in 53 children diagnosed with sleep abnormalities as experimental group and 32 healthy children as control group. The level of blood lead exposure was compared between the two groups. Results: The blood lead level was (0.68 ± 0.27) μmol / L in the experimental group and (0.51 ± 0.18) μmol / L in the control group, P <0.05). The abnormal blood lead level in the experimental group was 75.47% The control group was 21.88% (P <0.01). Conclusion: Children’s sleep abnormalities may be related to the increase of blood lead level.
