Background: Alcohol, tobacco and other drug use (ATOD) among adolescent and young adult couples during prenatal and postnatal periods is a significant public health problem, and couples may mutually influence each others' ATOD behaviors.

Purpose: The current study investigated romantic partner influences on ATOD among adolescent and young adult couples during pregnancy and postnatal periods.

Methods: Participants were 296 young couples in the second or third trimester of pregnancy recruited from OBGYN clinics between July 2007 and February 2011. Participants completed questionnaires at prenatal, 6 months postnatal, and 12 months postnatal periods. Dyadic data analysis was conducted to assess the stability and interdependence of male and female ATOD over time.

Results: Male partner cigarette and marijuana use in the prenatal period significantly predicted female cigarette and marijuana use at 6 months postnatal (b = 0.14, P < 0.01; b = 0.11, P < 0.05, respectively). Male partner marijuana use at 6 months postnatal also significantly predicted female marijuana use at 12 months postnatal (b = 0.11, P < 0.05). Additionally, significant positive correlations were found for partner alcohol and marijuana at pre-pregnancy and 6 months postnatal, and partner cigarette use at pre-pregnancy, 6 months and 12 months postnatal.

Conclusions: Partner ATOD among young fathers, particularly during the prenatal period, may play an important role in subsequent ATOD among young mothers during postnatal periods.
