Objective To prospectively examine the association between post‐traumatic stress disorder (PTSD) and weight change. Methods Longitudinal analysis techniques were used to examine data (2001–2008) from Millennium Cohort Study participants, consisting of U.S. service members and veterans. Using the PTSD Checklist–Civilian Version, PTSD was assessed as none, resolved, new onset, or persistent. Subsequent weight change was assessed as stable ( ≤ 3% loss or gain), >3% weight loss, >3% but <10% weight gain, and ≥10% weight gain. Results Of the 38,352 participants, 2391 (6.2%) had PTSD (838 resolved, 1024 new onset, and 529 persistent), and 11% of participants subsequently had ≥10% weight gain. In multivariable models, PTSD was associated with higher odds of ≥10% weight gain (new onset OR: 1.44 [95% CI: 1.20–1.73]; persistent OR: 1.51 [CI: 1.17–1.96]; resolved OR: 1.30 [CI: 1.05–1.60]) compared with those without PTSD. New‐onset and persistent PTSD were also associated with higher odds of >3% weight loss (OR: 1.41 [CI: 1.17–1.71]; OR: 1.42 [CI: 1.09–1.86], respectively). Conclusions PTSD is independently associated with a higher risk of weight gain and loss, the former of which leads to a higher prevalence of overweight and obesity and a higher risk of comorbidities associated with excessive body adiposity.
