The impact of underuse of modern methods of contraception among adolescents with unintended pregnancies in 12 low- and middle-income countries

摘要

BackgroundIn spite of the last decade increase in availability of contraception, around half of the annual 21 million pregnancies notified in low- and middle-income countries in individuals aged 15-19 years are unintended. We sought to explore the contribution of the underuse of modern methods of contraception (MMC) to the annual incidence of unintended pregnancies among adolescent women.
