Services to adolescent fathers.

Until recently, service programs for adolescent fathers have been rare. Such a program for teenage fathers and service characteristics that encourage the involvement of teenage fathers are described. In particular, fathers who did not live with the mothers of their babies had dramatically greater participation in prenatal activities if they used teenage father services. Services to fathers and fathers' participation in prenatal activities also were associated with higher birthweights. Engaging adolescent fathers in pilot fatherhood projects thus has high potential to benefit teenage fathers and mothers and their infants.
