Maternal personality disorder and babies' exposure to tobacco smoke.

This study examined the association between smoking practices and maternal personality disorder in a sample of 200 mothers of 2-month-old babies. Maternal personality disorder was robustly associated with allowing smoking in the home and also exposing the baby to tobacco smoke. The findings suggest that mothers with personality disorders might particularly benefit from targeting with education and advice about reducing their baby's exposure to environmental tobacco smoke in the postpartum period.
