Adolescence is a critical stage in life for physical, cognitive and emotional development, shaping future health and well-being. Comprehensive measurement of adolescent health is essential to prioritize health issues, guide interventions and track progress. However, global, regional and national adolescent health measurement has historically been inconsistent and incomplete. The Global Action for Measurement of Adolescent health (GAMA) Advisory Group has been established by the World Health Organization (WHO) in collaboration with United Nations (UN) partners to support efforts to focus adolescent health measurement on the most important issues and to improve alignment across different measurement initiatives. This document presents a list of 47 indicators recommended by GAMA for measurement of adolescent health. The systematic, participatory indicator selection process included five steps: identification of core measurement areas; a scoping review of adolescent health indicators for selected core areas; selection of draft indicators; further assessments of the draft indicators for implementation feasibility in countries, alignment with survey programmes and global data availability; and refinement and finalization of the indicators based on these assessments.
