  1. Child Behavior problems increased by maternal smoking during pregnancy.

    Article - En anglais

    We investigated the effects of maternal smoking during pregnancy on behavioral problems (i.e., not mediated by low birth weight) in 3-y-old offspring.

    We assessed behavioral problems in 1 377 2-to 3-y-old twin pairs (registered in the Netherlands Twin Register) with the Child Behavior Checklist for ages 2-3 y (CBCL/2-3) from Achenbach, Edelbrock, and Howell.

    Two to 3 y earlier (i.e., soon after the birth of the twins) we collected information about the smoking habits (i.e., « never, » « sometimes, » and « regularly ») of the mother during pregnancy.

    We analyzed the effect of maternal smoking on the CBCL total score and on several subscale scores for first-and second-born twins separately, and we adjusted for the possible confounding effects of birth weight, socioeconomic status, maternal age, and type of feeding (i.e., breast or bottle fed).

    There was a significant effect of maternal smoking on so-called « externalizing » behavioral problems (e.g., oppositional, aggressive, overactive), but not on « internalizing » behavioral problems (e.g., withdrawn, depressed, anxious), in both first-and second-born twins.

    The enhanced « externalizing » problems were attributed predominantly to increased aggression.

    Although boys have higher externalizing and aggression scores than girls, the effect of maternal smoking was the same for boys and girls.
