Doctors estimate the number of cases of Attention Deficit Hyperactive Disorder (ADHD) could be cut by one-third, by eliminating kids' exposure to cigarettes and lead.
Researchers at Cincinnati Children's Hospital Medical Center looked at records of mothers' who smoked during pregnancy. They also looked at results of blood tests for lead taken when the children were between eight and 15 years old.
They found kids whose mothers smoked when they were pregnant were more than twice as likely as other kids to be diagnosed with ADHD later. The risk was similar for those whose blood lead levels were highest. Exposure to both lead and smoking translated to an eight-fold increased risk.
Researchers estimate 35 percent of ADHD cases could be reduced by eliminated such toxin exposure.
