This study examined the association between fathers' and mothers' risk factors and paternal engagement one and three years post-birth. Distinguishing between new and persistent risk factors, we tested whether cumulative risk has unique effects on couples where one or both parents are adolescents at birth. Results indicated that while fathers' and mothers' risk factors affected levels of paternal engagement with one-year olds, these effects did not differ among couples with at least one adolescent and older couples. However, when the child was three, fathers' risk factors were stronger predictors of decreased engagement for couples with at least one adolescent partner, but mothers' risk factors increased engagement only for adolescent fathers with older mothers. Implications for policy and practice are discussed.
