Mental illness and social integration among suicide attempters in Copenhagen. Comparison with the general population and a four-year follow-up study of 100 patients.

In order to describe a population of suicide attempters in an affluent suburb of Copenhagen, 100 patients were interviewed, randomly chosen from a group of 246 patients referred to psychiatric consultation after a suicide attempt. The group consisted of 71 women and 29 men. Single status, abuse, and previous suicide attempts occurred frequently as did suicide among first-degree relatives. The most frequent reason for a suicide attempt was conflict with partners. In comparison with the normal population in the same catchment area, the patients were alone and felt lonely, but no difference was found in the group's relation to the labor market. After a four-year follow-up period, 9 persons had died by suicide. Borderline personality disorder and affective psychosis, no employment, 2 or more previous attempts, violent method and potential lethal attempt proved to be predictors of suicide later on. Alcohol and drug abuse, lack of social support and loneliness did not influence the risk.
