Factors Associated with Suicide in Four Age Groups: A Population Based Study

Area of Science:

• Public Health
• Epidemiology
• Psychiatry

Background:

• Suicide remains a significant public health concern with varying risk factors across the lifespan.
• Understanding age-specific patterns in suicide is essential for effective prevention.

Purpose of the Study:

• To compare suicide characteristics across four age groups.
• To identify differences in methods, demographics, mental health, and life events associated with suicide deaths.

Main Methods:

• Analysis of a database of suicide and undetermined intent deaths in Northern Ireland (2005-2011).
• Comparison of suicide methods, sex, occupation, mental disorders, prior attempts, and life events across age groups (N=1667).

Main Results:

• Hanging was a prominent method in the under-20 age group.
• Women were more likely to have a known mental disorder, increasing with age.
• Relationship difficulties were linked to suicides in males under 40.
• Physical health and life events were more relevant than mental illness in males over 61.

Conclusions:

• Suicide risk factors and methods are age-dependent.
• Tailored interventions considering age-specific factors are needed for suicide prevention.
• Incomplete data on life events highlights a need for more comprehensive reporting.
