Does body mass index moderate the association between posttraumatic stress disorder symptoms and suicidal ideation in Iraq/Afghanistan veterans?
Suicide, PTSD, and obesity co-occur at high rates among returning veterans, yet limited research exists regarding the relationship among these variables. Self-report and diagnostic interview data from a longitudinal study of Iraq and Afghanistan veterans (N=130) enrolled in VA healthcare examined these inter-relations. As hypothesized, body mass index (BMI) significantly moderated the association between PTSD and suicidal ideation such that the association between PTSD and suicidal ideation was strongest among individuals with a high BMI. Programs that focus on health promotion, trauma treatment, and weight management should continue to monitor suicide risk.
