According to the authors, «[a]lthough realizing that the findings of our study need to be replicated and extended, we conclude that, when combined, maternal prenatal smoking and mother’s history of antisocial behavior or family income present risks for antisocial behavior in offspring that exceeds their simple addition. Replication of these results will strongly suggest that support should be given from pregnancy onward to families where the mother is a heavy smoker and has a history of antisocial behavior problems, or where the mother is a heavy smoker and family income is low. There are programs that have already shown to benefit specifically disadvantaged families where the mother is a heavy smoker (see Olds et al., 1999). In this respect the interaction between maternal prenatal smoking and mother’s history of antisocial behavior might be particularly important and limited resources would be best prioritized for this relatively small group.» (p. 451)
