Suicide in schizophrenics, manics, depressives, and surgical controls. A comparison with general population suicide mortality

Abstract

This article reports suicide risk among 200 schizophrenic, 100 manic, and 225 depressive patients, and 160 surgical controls. The suicide experience of the study subjects was compared to that of the population of the state of Iowa, the geographical area and population from which the subjects were selected. The suicide experience of the surgical controls was not significantly different from that of the general population. On the other hand, increased risk of suicide was found in all psychiatric groups except female schizophrenics. Suicide appeared pronounced particularly in male patients with affective disorders during the first decade of the follow-up period.
