Populations in the global south are disproportionately exposed to the stressors of development, disaster and armed conflict, all of which heighten cardiovascular disease (CVD) risk. We consider how war-related stressors exert a lasting influence upon population health, in particular the cardiovascular health of war survivors now entering older adulthood. Data come from the 2018 Vietnam Health and Aging Study conducted among 2447 northern Vietnamese adults age 60 and older. We conduct survey-adjusted logistic regression analyses to examine the associations among respondents' wartime exposure to combat and physical threat, malevolent environment conditions, and four CVD conditions (hypertension, dyslipidemia, heart disease, and stroke). We examine posttraumatic stress disorder (PTSD) as it mediates the association between wartime stress exposures and late life CVD, and gender as it moderates the relationship between wartime stressors and CVD. We find that exposure to wartime combat and violence, as well as malevolent living conditions, exhibit significant, positive associations with cardiovascular conditions. These associations are mediated by the severity of recent PTSD symptoms. For certain CVD conditions, particularly hypertension, the associations between wartime stressors and late life cardiovascular conditions diverge across gender with women experiencing a greater penalty for their exposure to war-related stressors than their male counterparts. We conclude that the stressors of war and resultant PTSD, widespread in this cohort of Vietnamese older adults who endured myriad forms of war exposure during their young adulthood, exhibit modest, yet significant associations with late-life cardiovascular conditions. Women, especially those exposed to wartime violence and combat, bear this CVD burden alongside men.
