Posttraumatic stress disorder as a risk factor for obesity among male military veterans.

OBJECTIVE

Obesity is a significant public health problem in the United States, particularly among military veterans with multiple risk factors. Heretofore, posttraumatic stress disorder (PTSD) has not clearly been identified as a risk factor for this condition.

METHODS

We accessed both a national and local database of PTSD veterans.

RESULTS

Body mass index (BMI) was greater (P < 0.0001) among male military veterans (n = 1819) with PTSD (29.28 +/- 6.09 kg/m(2)) than those veterans (n = 44 959) without PTSD (27.61 +/- 5.99 kg/m(2)) in a sample of randomly selected veterans from the national database. In the local database of male military veterans with PTSD, mean BMI was in the obese range (30.00 +/- 5.65) and did not vary by decade of life (P = 0.242).

CONCLUSIONS

Posttraumatic stress disorder may be a risk factor for overweight and obesity among male military veterans.
