Van den Berg, B,, Grievink, L., Yzermans, J. et al. (2005). Medically Unexplained Physical Symptoms in the Aftermath of Disasters. Epidemiologic Reviews. 27(1): 92-106.
The authors discuss the prevalence of certain "Medically Unexplained Physical Symptoms" (MUPS) that arise in some disaster/traumatic event survivors which may help inform healthcare preparedness strategies. They conducted a literature review on 20 years' worth of articles and found the following consistent risk factors for MUPS: gender (females were more likely to suffer from these symptoms); high physical damage linked to the event; and posttraumatic stress symptoms.
