Military Combat and Risk of Coronary Heart Disease and Ischemic Stroke in Aging Men: The Atherosclerosis Risk in Communities (ARIC) Study

PurposeTo assess the long-term association of military combat stress with coronary heart disease (CHD) and ischemic stroke (IS).MethodsThe association between exposure to military combat and the occurrence of CHD and IS was assessed among 5,347 men in the Atherosclerosis Risk in Communities (ARIC) study. Outcomes were assessed an average of 36 years after entry into military service during the eras of World War II, the Korean War, and the Vietnam conflict.ResultsVeterans were more likely to be older, white, and of higher socioeconomic status than non-veterans. No differences in CHD period prevalence rates were noted among the three exposure groups, overall or by era of service. Associations between combat and ischemic stroke period prevalence may be modified by father's education, although confidence intervals were wide and event rates small.ConclusionsOverall, middle-aged veterans with distant combat exposure are not at increased cardiovascular risk compared to those without combat exposure.
