Men's tobacco and alcohol use during and after pregnancy.

Men's health risk behaviors are rarely considered as a component of their partners' prenatal care. Men living with a pregnant partner completed telephone surveys at two time points, during pregnancy and postpartum, answering questions about tobacco and alcohol use behaviors and other sociodemographic variables. Men's smoking did not change significantly from pregnancy (46.9%) to postpartum (45.8%). Hazardous drinking (five or more drinks/day in a month) changed from 27.1% to 22.9%. Nonsmoking status of men was significantly related to a pregnant partner's quitting smoking during pregnancy and remaining quit at postpartum (p = .019). Household prohibitions from indoor smoking increased from 62.5% at pregnancy to 76% postpartum (p = .009). Pregnancy alone does not appear sufficient for men to quit smoking or change hazardous drinking. Continued exclusion of young men during prenatal care is a missed opportunity to address health risk behaviors and improve paternal, maternal, and family health.
