Correlation analysis of blood lead and zinc with tic disorders in children / 中国基层医药

ABSTRACT

Objective To analyze the correlation between blood lead,zinc levels and tic disorders(TD) in children.Methods One hundred and fourteen children with TD were chosen as observation group,and 100 healthy children were chosen as control group.The serum levels of lead and zinc were compared between the two groups,and the correlation between blood lead,zinc levels and TD was analyzed.Results The serum level of blood lead in the observation group was (70.8 ± 14.9) μg/L,which was higher than (50.9 ± 13.8),μg/L in the control group,the difference was statistically significant(t =4.932,P ＜ 0.05).The serum level of blood zinc in the observation group was (461.4 ±33.2)μg/L,which was lower than (501.5 ± 34.1)μg/L in the control group,the difference was statistically significant(t =5.217,P ＜ 0.05).The serum level of blood lead ≥60μg/L and the serum level of blood zinc ＜470μ g/L were significantly related with TD(OR =2.192,2.012,all P ＜ 0.05).Conclusion The blood lead and zinc levels are significantly correlated with TD in children.
