The relationship between social and economic aspects of displacement, traumatic events, health, posttraumatic stress disorder (PTSD) and co-occurrence was studied in a sample of 93 poor and displaced people. The Davidson Trauma Scale (DTS), and Goldberg's General Health Questionnaire (GHQ-28) were applied. Of all the participants, 50.5% had PTSD and 74.2% had health problems. Co-occurrence was observed between PTSD symptoms and health problems, with a strong relation between anxiety (GHQ-28) and hyper-reactivation (DTS). Scores on the DTS were related to the existence of health problems; the scores on the GHQ-28, the issuing department and the type of displacement, all of these were related to PTSD. Scores on the DTS and the issuing department influenced the existence of co-occurrence.
