This quarterly digest syntheses the latest research findings in adolescent well-being over the previous three months. In this issue of the Adolescence Research Digest we highlight the results of the ground-breaking Lancet Commission on adolescent health and wellbeing, which were presented in London in May and Washington in June. The Digest also includes the lasts news, upcoming events, resources and the latest high profile research studies on adolescent well-being and health. Additional readings are also listed. The Digest aims to promote awareness and uptake of new adolescent well-being research findings amongst UNICEF staff, practitioners, policymakers and academics in the development and humanitarian sectors.
