Abstract

Objective

Posttraumatic stress disorder (PTSD) has frequently been found to have an effect on the development of obesity, a relationship usually thought of as unidirectional. The purpose of this study was to examine whether the level of PTSD symptoms would decrease as a result of weight loss.

Method

In a repeated measures design, PTSD symptoms, depression symptoms, social support, and weight were assessed in obese participants during 16 weeks at a weight loss facility.

Results

The participants’ body mass index decreased significantly, and concurrently, a significant decline in the level of PTSD symptoms and depression symptoms was observed.

Conclusions

The beneficial effects of weight loss on depression are consistent with previous work. The decline in the level of PTSD symptoms simultaneously with weight loss is an important and positive effect that has not been reported previously.
