Scientists now believe there's an association between an increased risk of ADHD and some additional environmental factors.
The German study suggests that children born to mothers who developed high blood sugar during pregnancy, were almost twice as likely to develop attention-deficit/hyperactivity disorder as children born to mothers without gestational diabetes.
The study also found more than double the risk of ADHD for children born into a family with a low socioeconomic status compared to those in the highest socioeconomic class. Children in the middle class had almost a 60 percent higher rate of ADHD compared to the upper-class children.
The study showed an association; however, the study did not prove these environmental factors caused ADHD.
The good news from this study is children who were breast-fed were almost 20 percent less likely to develop ADHD.
The study results appear in the latest online issue of the Archives of Pediatrics & Adolescent Medicine.
