Around half of adolescent pregnancies in low- and middle-income countries are unintended, contributing to millions of unsafe abortions per year. Adolescents 360 (A360), a girl-centred initiative, aimed to increase voluntary uptake of modern contraceptives among adolescents in Nigeria, Ethiopia and Tanzania. This article, published in Plos Global Public Health presents the results of a outcome and cost-effectiveness evaluations of A360’s first phase. The study used before-and-after cross-sectional studies of adolescent girls in four settings. Two Nigerian settings had purposefully selected comparison areas. Baseline and endline household surveys were conducted.

We suggest to read this alongside the summative report for A360’s external evaluation and A360’s Management Response.
