Background. All prisoners' suicides in Finland during 1969-1992 (n=184
) were studied. Method. The data were collected from official document
s. Results. Of all prisoners' deaths, 47% were suicides. The rate of s
uicide among male prisoners was three-fold compared to the normal adul
t Finnish male population. More than half of those committing suicide
had a psychiatric disturbance and one half of them had visited the pri
son health services because of a psychiatric problem not more than one
week before the suicide. Almost one third of the suicides were commit
ted in isolation rooms. Contrary to the findings of many previous stud
ies, there was no concentration of suicides at weekends, on religious
holidays, in different seasons nor at the beginning of the confinement
. Conclusions. The most important finding of this study was the common
use of health care facilities in the prison just before the suicide.
It is important to try to develop the means to recognize suicidal idea
tion among all prisoners seeking psychiatric care. The surveillance of
prisoners in isolation cells needs to tighten up and should probably
be continuous. (C) 1997 Elsevier Science Ireland Ltd.
