Adolescents

This second edition of AA-HA! guidance to support country implementation builds on the first edition published in 2017. It is a collaborative effort spearheaded by the World Health Organization in collaboration with UNAIDS, UNESCO, UNFPA, UNICEF, UN WOMEN, the World Food Programme and PMNCH.

Building on the solid foundation of the first edition and voices of adolescents and young adults around the world, this multi-agency product has evolved to incorporate valuable learnings from the past six years, including of the COVID-19 pandemic's impacts. Latest estimates of mortality and disease burden, updated evidence, and a broader focus on wellbeing make the second edition a cutting-edge resource for policy makers in the area of adolescent health and well-being.

AA-HA! 2.0 offers insights into the current health and well-being landscape of the world’s over 1.2 billion adolescents, underlining evidence-based solutions and presenting strategies for priority setting, planning, implementing, and evaluating health and well-being programmes. The inclusion of key implementation strategies and real-world case studies make this guide a practical tool for governments in designing and implementing a new generation of adolescent health and well-being programmes.

This synthesis report reflects a comprehensive review of the body of research undertaken through the Evidence-to-Action partnership.

With support from the Joint UN 2gether 4SRHR programme, a research partnership with the University of Oxford and University of Cape Town was established with the aim to improve HIV, SRH, and the overall well-being of adolescents by providing sustainable and scalable services. The partnership, which was ongoing from 2018 to 2023, investigated drivers of HIV and SRH risk in adolescents, and was committed to generating and using the latest evidence to propose practical solutions, shape programmes and guide decision-making for adolescents.

The results of the partnership are being used in integrating evidence into programming for adolescents throughout the region. They are summarized in a synthesis report, along with the six evidence-to-action briefs featured here.
