Abstract
Abstract Cardiovascular disease (CVD) is prevalent among older adults, but studies often focus on individual spouses rather than couple dynamics. This study examines how interplay between spouses—specifically discordance in gender role attitudes—relates to CVD risk biomarkers, using couple-matched data from the Korean Social Life, Health, and Aging Project (KSHAP) on 308 older married couples (616 individuals). Actor-partner interdependence models (APIM) reveal that discordant gender role attitudes are significantly associated with higher CVD risk markers—higher systolic blood pressure, higher
