Suicide in prison.

Records of 186 suicides among male prisoners in England between 1958 and 1971 emphasize the differences between the prison population and the population at large. The suicide rate may well be three times greater. The records show that sentence of more than 18 months' duration, whether anticipated or actually received, is associated with a greater risk of suicide than shorter sentence, and that suicide is most likely to be committed during the first few weeks in custody.
