Objectives: To examine educational gradients in overall and cause-specific mortality among elderly married men and women and their spouses.
Methods: Using the census-based Israel Longitudinal Mortality Study (1983-92), 13 573 married men and 6563 married women were identified who were aged 70-89 years at baseline. Cox proportional hazard models were used to assess the strength of the association between education and overall and cause-specific mortality.
Results: Educational gradients for own and spouse's mortality varied by gender and cause of death. In particular, in relation to cardiovascular disease, men married to uneducated wives experienced elevated mortality risks [hazard ratio (HR) = 1.30; 95% confidence interval (95% CI) 1.11-1.52]. Women were generally unaffected by their husband's education, except for those who died from non-breast cancer, for whom husband's low education had a harmful effect (HR = 1.98; 95% CI 1.26-3.11).
Conclusions: Mortality among elderly married persons is associated with one's own and one's spouse's educational achievement. Research using partner's education as a proxy for one's own attainment may be omitting valuable information regarding these and other health risks.
