Investigation of adolescent health

In 2012, adolescents and young adults made up a quarter of the world's population, with 90% of them residing in low- and middle-income nations. More recently, there has been agreement that funding adolescent development and health is essential to the post-2015 developmental agenda's success. We sought to test the efficacy of several interventions found in our conceptual framework in enhancing the health of adolescents in this series of publications. We compiled the available evidence in a methodical manner. This article provides an overview of the backdrop, conceptual framework, and evidence-synthesis technique. It is followed by seven articles providing evidence-based summaries of interventions for mental health, substance misuse, nutrition, immunizations, accidents/injury, and sexual/reproductive health. The series’ final article provides a summary of the findings from every earlier item in the series, as well as the evidence's applicability to action in the post-2015 Millennium Development Goals period, evidence gaps, and future research goals.
