The world is home to 1.2 billion adolescents: the largest cohort of this age-group in history. Adolescence is a critical period of cognitive, emotional, physical and sexual development with consequences that stretch far into adulthood. The period also provides a second “window of opportunity” to build on early investments, promote positive behaviours, and offer a second chance to those who fared less well in early childhood.
90 per cent of adolescents live in low- and middle-income countries. Despite an increasing focus on their well-being, comprehensive data collection systems and research for effective interventions are lacking. This is particularly true for younger and disadvantaged adolescents.
Developed with Columbia University and experts from the Lancet Commission on Adolescent Health and Wellbeing this series of briefs provides a much needed review of contemporary research methodologies for adolescent well-being in low- and middle-income countries, covering: indicators and data sources, ethics, research with disadvantaged and vulnerable groups, participatory research, measurement of the social and structural determinants of adolescent health, and adolescent economic strengthening interventions.
The aim of these briefs is to improve efforts to collect rigorous evidence for programmes and policies on adolescent health and well-being. They will assist a wide range of professionals and stakeholders who conduct, commission or interpret research findings to make decisions about programming, policy and advocacy.
This initiative was funded by the UK Department for International Development. The Editors of the series were John Santelli, MD, MPH, Columbia University and Nikola Balvin, PsyD, UNICEF Office of Research – Innocenti.
