Case-control study of suicide attempts in the elderly

Area of Science:

• Geriatric Psychiatry
• Suicidology
• Mental Health Research

Background:

• Limited research exists on the link between subclinical symptoms and suicidal behavior in older adults.
• This study investigates the risk factors, including subclinical symptoms and cognitive impairment, in late-life suicide attempters.

Purpose of the Study:

• To assess the risk associated with subclinical symptoms, mild cognitive impairment, and clinical factors among elderly individuals who attempted suicide.
• To identify specific symptom clusters that predict suicidal behavior in the elderly population.

Main Methods:

• A case-control study involving 43 elderly suicide attempters and 43 comparison subjects.
• Utilized diagnostic interviews and screening tools like the Geriatric Depression Scale (GDS), Mini-Mental State Examination (MMSE), and the Brief Rating Scale for Mental Health (BSRS-5).
• Employed multiple logistic regression to calculate adjusted odds ratios.

Main Results:

• Suicide attempters were more likely to have a diagnosis of depressive disorder, even after adjusting for BSRS-5 scores and drinking habits.
• A BSRS-5 score exceeding 5 points was associated with a 17.8-fold higher odds of suicide compared to scores of 5 or less.

Conclusions:

• Subclinical symptoms, including anxiety, depression, hostility, sleep, and interpersonal issues, significantly impact suicidal behavior in older adults.
• The BSRS-5 is a valuable tool for assessing subclinical symptoms and may aid in preventing late-life suicidal behavior in primary care settings.
