All-cause mortality risk for men and women in the United States: the role of partner’s education relative to own education

ABSTRACT

This study examines the association between educational attainment, relative to that of an intimate partner, and all-cause mortality for men and women in different-sex relationships. Research suggests some health benefits for partnered adults that arise from economic benefits and improved access to health-promoting tools. One way these benefits could be gained is through the pairing of the highly educated. While high individual educational attainment lowers mortality risk, less is known about the risks of mortality associated with one’s education, relative to their partner’s education. Using National Health Interview Survey Linked Mortality Files (NHIS-LMF) for the years 1999–2014 with prospective mortality follow-up through December 2015 (N = 347,994), we document the association between relative educational attainment and mortality for men and women with different-sex partners in the United States. Fully adjusted Cox proportional hazard models revealed a higher risk of all-cause mortality for men and women who have more education than their partner, relative to those having the same education as their partner. For women only, having less education than their male partner was associated with a lower risk of all-cause mortality. A better understanding of relative status within different-sex partnerships provides insights into partnered adult’s mortality risks.
