^a Participants in this study completed a baseline survey in 2001–2003 and completed a follow-up survey in 2004–2006. Marital status assessed from baseline to first follow-up, where those who were “recently divorced” were married at their baseline survey and got divorced before their follow-up survey, those who “stayed married” were married throughout the study period

^b All characteristics were significantly associated with exposure at p < 0.05, except for service branch (p = 0.74)

^c Potential alcohol dependence is defined as at least 1 positive response to the CAGE questionnaire (Cutting down, Annoyance by criticism, Guilty feeling, and Eye-openers)

^d Body mass index is defined using Center for Disease Control and Prevention standards of Underweight (Less than 18.5 kg/m²), Normal range (18.5-24.99), Overweight (25–29.9), and Obese (≥30.0)

^e Mental component summary score and physical component summary score are obtained from the Short Form-36 Question Health Survey for Veterans (SF-36 V)
