a series of national collaborating groups were formed. In 2005 and 2006, the institute expanded its scope even further, targeting social inequalities in health and establishing a division for mental health. FHI also took on responsibility for the prevention of injury and disease caused by behavioural factors such as smoking, abuse of alcohol and illicit drugs, physical inactivity, obesity and unprotected sex with unknown partners. The Norwegian Institute of Forensic Medicine was transferred from the University of Oslo to the Norwegian Institute of Public Health in 2011, but became part of Oslo University Hospital in 2017. The Norwegian Institute for Alcohol and Drug Research became part of the Norwegian Institute of Public Health in 2016. In 2019 the Norwegian Centre for Violence and Traumatic Stress Studies will be transferred from the University of Oslo to the Norwegian Institute of Public Health. Size In 1929, the institute had 18 employees, increasing to over 1400 in 2016. The annual budget increased from 107,000 to 1 billion Norwegian kroner in the same period. Even taking currency value increases into account, the 1929 budget was extremely low and most of the employees were volunteers. The considerable budget growth from 1929 to 2007 may be seen as a manifestation of the enormous changes in the national economy during this period. It may also reflect attitude changes and increasing awareness of effective preventive measures in relation to public health. Activities The institute focuses on preparedness in the field of communicable diseases and environmental medicine, mental health, drug research, health, population studies, laboratory-based research and surveillance. FHI's activities adapt to diseases in the population and challenges in health care and society.
