The Relationship Between Children Attention-Defici Thyperactivity Disorder And The Levels Of Blood Lead, Microelements And Polyunsaturated Fatty Acids

Objective: To investigate the relationship between children attention deficit/ hyperacitivity disorder and the levels of blood lead , microelements and polyunsaturated fatty acidsMethods: To randomized choose the children who were diagnosed ADHD by the psychiatrist , and match the normal children as control group . To compare the levels of blood lead , microelements and polyunsaturated fatty acids between the two groups.Results : The blood lead levels were significantly higher in ADHD than that in control group(p<0.0001). However, the levels of blood lead in the ADHD were significantly lower than American CDC standard of 100μg/L. The levels of blood ALA,DHA,AA were significantly lower in ADHD than that in control group . The levels of blood microelements and DHA were not significantly difference between the two groups.Conclusion : Lower lead exposure and deficit of the polyunsaturated fatty acids might play an important role in the ADHD. We should pay attention to assess blood lead and polyunsaturated fatty acids levels in children.
