After reading the Arsenault article I couldn't help but wonder, have any studies been done to track the behavior of children born during OB complications from 'supportive' families? What is the damaging factor that seems to be undone by stable supportive families? Is it that these children have learned to suppress violent or deliquent behavior?

My next question is, what are the rates of complications in births from 'at risk' mothers? Is it possible that the mothers of children who are violent and delinquent have higher risk of OB complications, possibly because of lower SES factors?

What is the percentage of birth complications in the general public?

I also wonder what the common factor is between each of the complication factors studied. I imagine the prolapsed cord and forceps can easily restrict blood flow during delivery, but what is the common factor in preeclampsia and induction? Is it possible that these difficult deliveries interfere with the at risk mother's bonding with her child?

Just so many questions, and possible confounds....
