Area of Science:

  • Epidemiology
  • Public Health
  • Psychiatry

Background:

  • Suicide rates exhibit temporal variations influenced by demographic and societal factors.
  • Understanding seasonal and weekly patterns in suicide is crucial for targeted interventions.
  • Previous research suggests potential links between specific days/months and suicide risk.

Purpose of the Study:

  • To investigate the independent effects of month and day on suicide rates in Ireland.
  • To analyze differences in suicide risk between working days, holidays, and weekends.
  • To examine gender-specific and age-specific temporal patterns in suicide.

Main Methods:

  • Analysis of Irish national suicide data from 1990-1998.
  • Statistical adjustment for age, gender, and calendar year effects.

  • Comparison of suicide rates across different days of the week (including working/holiday Mondays) and months.

    • Main Results:

    • Male suicide rates were significantly elevated on working Mondays (+31%) and Saturdays (+14%).
    • Higher male suicide rates were observed in April, June, and August (+17%).
    • Female suicide rates showed an increase only in August (+35%) with no day-specific effect; teenage males exhibited heightened risk on Saturdays, Sundays, and Mondays.

    Conclusions:

    • Specific days (working Mondays, Saturdays) and months (April, June, August) are associated with increased suicide risk, particularly for males.
    • Teenage males represent a vulnerable group with distinct temporal risk patterns.
    • Findings inform the strategic planning of mental health services and helplines, and support existing theories on suicide causation.
