Contraception and abortion knowledge, attitudes and practices among adolescents from low and middle-income countries: a systematic review.

The reported observations suggest severe limitations in the access to safe and effective methods of contraception and safe abortion services. There is a need for an urgent response in reducing the "unmet needs" for contraception and to improve access to contraception, abortion information, and services in this group. Interventions which target the involvement of parents and teachers should be considered, to carry one wholesome message to the adolescents.
