Do suicide characteristics differ by age in older people?

Area of Science:

• Gerontology
• Public Health
• Psychiatry

Background:

• Suicide rates significantly increase in individuals aged over 65 years.
• Understanding the specific characteristics of late-life suicide is crucial for effective prevention strategies.

Purpose of the Study:

• To detail the characteristics of older adults who died by suicide.
• To examine age-related differences in suicide characteristics across three distinct age bands (65-74, 75-84, and 85+ years).

Main Methods:

• Analysis of national coroner records for suicides in individuals aged 65 and older (n=225) in New Zealand.
• Comparison of socio-demographic and clinical factors across three age bands (65-74, 75-84, 85+ years) from July 2007 to December 2012.

Main Results:

• Older age correlated with increased likelihood of being widowed but decreased likelihood of prior psychiatric admission or recent psychiatric service contact.
• A majority of older adults (61.7%-77.3%) had contact with their general practitioner within one month of suicide.
• While women were less likely to use violent methods than men, increasing age saw men using less violent methods.

Conclusions:

• Suicide characteristics among older adults vary significantly by age group.
• The oldest individuals dying by suicide may not be under psychiatric care, highlighting the potential benefit of primary care interventions.
• Screening for depression and suicide risk within primary care settings could be a vital approach for preventing suicide in older populations.
