Health care and health outcomes for adolescent mothers and their children may be a result of a complex interaction between socioeconomic, psychological, and familial factors. To examine a health professional perspective on the important issues in providing health care for adolescent mothers, transcripts of seventeen interviews with health professionals were analysed. Social support was considered an important aspect influencing the health of adolescent mothers and their children. This included family support, peer support and organisational support. Opportunities for health professionals to promote good social support for young mothers include role modelling supportive care and supporting adolescents' decision making, providing referrals to peer support groups, and understanding barriers to accessing organisational support. The best outcome for adolescent mothers is when their role as mother is supported by the family and wider support network.
