Causes of death in a widowed population

Area of Science:

• Epidemiology
• Public Health
• Gerontology

Background:

• The mortality patterns of widowed individuals compared to married individuals are not fully understood.
• Previous research has not conclusively determined if bereavement impacts mortality risk, particularly for those with pre-existing chronic conditions.

Purpose of the Study:

• To compare the causes of death between widowed and married individuals.
• To investigate if bereavement exacerbates mortality risk in individuals with chronic diseases.

Main Methods:

• A nonconcurrent prospective study in Washington County, Maryland.
• Matched 4032 widowed individuals (1963-1974) with 4032 married individuals based on race, sex, birth year, and residence.
• Analyzed underlying causes of death from death certificates.

Main Results:

• Widowed males showed significantly higher deaths from infectious diseases, accidents, and suicide.
• Widowed females exhibited significantly higher deaths from liver cirrhosis.
• No increased mortality risk was observed for widowed individuals with chronic diseases (≥2 years duration) after bereavement.

Conclusions:

• Bereavement is associated with specific elevated mortality risks for widowed males and females.
• The risk of premature death following bereavement is not amplified by pre-existing chronic diseases.
