This report surveys different aspects of health of unaccompanied minors who have arrived in the Nordic region. The focus is on mental health issues rather than physical health, as the former are usually seen as posing more of a challenge to successful integration and to the social and health services in the Nordic countries. The report builds on recent research and studies, mainly from 2012 onwards. Older studies have been included if they offer additional insights. As the emphasis is on Nordic research, international research on migrant mental health is less referred to. This report is not a systematic review of all Nordic research, but rather a snapshot of main studies and reports. It highlights and summarises some of the knowledge from both general overviews and specialised scientific literature. Much of the research and data come from national bodies of social, health, and integration issues, research institutions, and universities. Some reports, overviews, and evaluations are outcomes of projects granted by ministries and directorates to different research institutions.
