The current study examinedage differences in allostatic load among nonveterans, noncombat veterans, and combat veterans. Participants included 280 individuals from the Midlife Development in the United States (MIDUS) survey, including 164 veterans (n = 48 combat veterans; n = 116 noncombat veterans) and 116 nonveterans. Age differences in allostatic load were similar among nonveterans and noncombat veterans, B = 0.002, SE = .011, p = .878, with older adults showing higher levels of allostatic load than their comparatively younger counterparts. Among combat veterans, however, a different pattern emerged. In this group, levels of allostatic load were similar across age, seemingly due to higher levels of allostatic load among younger combat veterans, B = -0.029, SE = .014, p = .031, ƞp 2 = .022. Results reveal the importance of considering combat exposure when examining health outcomes of military veterans, particularly in the context of age.
