Abstract
This study examines the relationship between spousal education and hypertension risk among older couples. Using data from the National Social Life, Health & Aging Project (NSHAP) Round 3 (2015-2016), we analyzed 1,214 couples aged 50 and older. Hypertension was assessed through biological and self-reported measures. Spousal education was categorized by college degree attainment. The Actor-Partner Interdependence Mediation Model (APIMeM) was used to examine the mediating roles of economic resources and health behaviors. Results showed that a wife's college degree was associated with lower hypertension risk for both spouses, whereas a husband's college degree showed no significant association. Mediation analysis revealed that health behaviors, but not economic resources, partially explained this relationship. Findings suggest that a wife's education plays a greater role in a couple's hypertension risk than a husband's, emphasizing the need for interventions targeting couples with a lower-educated wife to improve cardiovascular health in older adults.
