Widowhood and mortality risk in Taiwan: a population-based matched cohort study.

This study investigates the increased mortality risk associated with widowhood in Taiwan, analyzing data from over 800,000 widowed individuals and matched married controls using the National Health Insurance Research Database and National Death Registry. Findings indicate that widowhood raises overall mortality risk by 32% for men and 27% for women, with higher risks observed shortly after spousal death, among younger widowed individuals, and when the spouse died by suicide, accidents, endocrine, gastrointestinal disorders, or infections. The study also reveals that widowed individuals are more likely to die from the same causes as their deceased spouses in these categories, suggesting shared environmental or lifestyle factors contribute to mortality patterns. These results underscore the need for targeted healthcare policies addressing mental health, safety, and chronic disease management tailored to the unique circumstances of widowed individuals.
