Suicide in Northern Ireland: a comparison of two quinquennia (1982-1986 and 1987-1991).

This study compares government records of death by suicide, in Northern Ireland, during two quinquennia in the decade 1982-1991. Specifically these quinquennia are 1982-1986 and 1987-1991. During the latter quinquennium there was an increase in rate for males in most age groups, except the 45-54 and the over 65 years age groups. However, females had an increase rate in the 15-24 and 35-54 years age groups, but have a decreased rate in the other age groups. There has been a decrease in the rate of suicides by poisoning with solids and liquids for both sexes. However, male suicide rates by more violent methods have increased substantially during the latter quinquennium. Three cohorts of males, those in the 15-24, 25-34, and 55-64 age groups, have shown substantial increases during the latter quinquennium. Suggestions for psychiatric intervention strategies are made.
