Younger adults attempting suicide are more likely to use high-lethality methods. This finding highlights age as a significant risk factor in suicide attempt lethality, differentiating attempters from ideators.

Area of Science:

  • Psychiatry
  • Public Health
  • Epidemiology

Background:

  • Understanding suicide attempt characteristics is crucial for prevention.
  • High-lethality suicide attempts share features with completed suicides, while low-lethality attempts may resemble ideation.
  • Limited research exists on the specific demographic and clinical profiles of high-lethality suicide attempters.

Purpose of the Study:

  • To compare demographic and clinical features of high-lethality suicide attempters with completed suicides.
  • To determine if low-lethality attempters align with non-attempter ideators' clinical profiles.
  • To identify risk factors associated with high-lethality suicide attempts.

Main Methods:

  • Retrospective chart review of adult suicide ideators (n=50) and attempters (n=50) at an urban tertiary care hospital.
Keywords:

  • Data collection included demographics and clinical characteristics (e.g., psychiatric diagnosis, prior attempts).
  • Suicide attempt method and lethality were assessed using the medical Lethality Rating Scale.

    • Main Results:

    • High-lethality attempters were significantly younger than low-lethality attempters and ideators (p=0.026, p=0.041).
    • A significant inverse correlation was found between suicide attempt lethality scores and age (p=0.017).

    Conclusions:

    • Younger adult age is identified as a risk factor for high-lethality suicide attempts.
    • Further research requires standardized definitions for high-lethality attempts and longitudinal studies.
    • Findings contribute to the growing body of literature on high-lethality suicide attempter characteristics.
