The aim of this study was to determine posttraumatic stress symptoms of people still living in the Marmara region 15-18 months after the earthquakes, that occurred there and examine differences in the nutritional status of these people. A daily nutrient consumption form and symptom checklist were used to collect data. Results indicated that there was no significant difference among the body mass index groups on the Global Symptom Index. However, underweight and normal-weight people had higher paranoid thoughts than obese people. On psychotic tendencies, underweight individuals were more negative than obese survivors.
