Intro:

Results: We documented a threshold effect of smoking 10 cigarettes or more per day during pregnancy on subsequent externalizing behaviors among 18-month-old children, even after adjusting for relevant confounders (odds ratio 1.32, 95% confidence interval 1.03-1.70). The child's sex did not moderate these effects (odds ratio 0.98, 95% confidence interval 0.83-1.16).

Conclusions: Maternal smoking during pregnancy increases offspring's subsequent risk for externalizing behavior problems at 18 months of age. The pattern of risk does not differ between boys and girls.
