Marital status, health and mortality

Area of Science:

• Gerontology
• Sociology
• Public Health

Background:

• Marital status and living arrangements significantly influence health and mortality.
• Unmarried individuals generally experience poorer health and increased mortality risk, particularly men.
• Changes in partnership and living arrangements in older age, including rising divorce rates, necessitate re-evaluation of their health implications.

Purpose of the Study:

• To review literature on the health and mortality implications of marital status and living arrangements.
• To address debates on selection bias (less healthy individuals into singlehood) and the impact of life-course transitions on health.
• To argue for a life-course perspective in understanding how changes in living arrangements affect health and mortality.

Main Methods:

• Literature review of studies examining marital status and living arrangements.
• Distinction between research using cross-sectional versus longitudinal data.
• Analysis of debates concerning selection effects and the timing of life-course transitions.

Main Results:

• Consistent findings show unmarried individuals have poorer health and higher mortality.
• Research debates exist regarding selection into singlehood and the differential impact of early versus later life transitions.
• A comprehensive understanding requires considering transitions throughout the entire life course.

Conclusions:

• Health and mortality are linked to marital status and living arrangements across the life span.
• Future research must adopt a life-course perspective to fully understand the determinants of health and mortality transitions.
• Considering cumulative changes in living arrangements throughout life is essential for accurate health outcome prediction.
