Physical vulnerability and fatal self-harm in the elderly.

Area of Science:

• Toxicology
• Gerontology
• Public Health

Background:

• The high global suicide rate among the elderly is often attributed to greater suicidal intent.
• Clinical observations suggest elderly Sri Lankans may die from less severe poisonings.
• Yellow oleander poisoning presents a significant public health concern, particularly in certain regions.

Purpose of the Study:

• To investigate the impact of age on mortality outcomes in yellow oleander poisoning.
• To determine if advanced age increases the risk of death from poisoning, independent of other factors.
• To re-evaluate the contributing factors to high elderly suicide rates in the context of poisoning.

Main Methods:

• Retrospective analysis of 1697 yellow oleander poisoning cases.
• Statistical modeling to control for confounding variables such as gender and ingested dose.
• Comparison of mortality rates across different age groups, with a focus on the elderly (over 64) versus young adults (under 25).

Main Results:

• Elderly individuals (over 64 years) were 13.8 times more likely to die compared to younger individuals (under 25).
• This increased mortality risk persisted even after adjusting for gender and the amount of poison ingested.
• The findings indicate age is a significant predictor of outcome in yellow oleander poisoning.

Conclusions:

• Advanced age is a critical risk factor for mortality in yellow oleander poisoning.
• The higher suicide rate in the elderly may be partly explained by their reduced ability to survive poisoning and subsequent medical treatment.
• This study highlights the need for age-specific considerations in managing poisoning cases and suicide prevention strategies for the elderly.
