Objectives
Adverse childhood experiences (ACEs) are known to be associated with morbidity and premature death, but the association between ACEs and mortality among older people is unknown in Japan, and whether marital status modifies the associations remains unclear.
Methods
We analyzed data from 12,698 older adults (65+ years) participating in the Japan Gerontological Evaluation Study (JAGES; response rate 70.3 %) in 2013 and were followed for 6 years. ACEs and marital status were assessed at baseline, and mortality was prospectively followed. Cox proportional hazards models were used to assess the association between ACEs and mortality, stratified by sex and marital status adjusted for covariates.
Results
1948 deaths occurred during the follow-up (Men: 1,238, Women: 710). We found no association between ACEs and mortality overall for both sexes. When stratified by marital status, among divorced/unmarried men, those having 3+ ACEs were 4.00 times more likely to die (95 % CI: 1.46–10.95), although there was no association between ACEs and mortality among married men. In contrast, among divorced/unmarried women, having ACEs showed a lower risk of mortality, and married women also showed no association between ACEs and mortality.
Discussion
ACEs were associated with mortality among divorced/unmarried older men, which is not true for married men and all women. Further research is warranted to elucidate the mechanism to prevent the adverse effect of ACEs on mortality among divorced/unmarried men and all women.
