Somatic diseases and suicidal behaviour

The association between somatic disorders and suicidal behaviour has been examined in many studies. Despite large variation in quality and study design, recent studies have improved our knowledge substantially, not only regarding the extent of risk but also factors influencing the risk. Most studies have been conducted in European countries, the US, Australia, Japan, and South Korea. A series of studies have examined suicide risk in relation to somatic disorders of older persons, while others addressed somatic disorders and attempted suicide in children and youth. Physical conditions may play an important role in medical settings, regardless of whether mental disorders are present or not, though especially when mental disorders are present. This chapter presents a review of present knowledge on suicide and suicidal behaviour in selected somatic disorders and pain syndromes, with a focus on studies from different parts of the world.
