title: Chickens and eggs-how should we interpret environment-behavior associations?
abstract: As usual, the research published in this issue of the Journal of Child Psychology and Psychiatry contains impressive state-of-the-science studies of child and adolescent psychopathology and related issues. Breeman and colleagues, for example, found that children born before 32 weeks gestation or with a very low birth weight (<1,500 g) were not only more frequently diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) during childhood, but continued to have an increased risk for attention problems up through early adulthood.
