J Anxiety Disord. 2014 Jan;28(1):75-82. doi: 10.1016/j.janxdis.2013.12.001. Epub 2013 Dec 14.


The objective of the study was to examine trends in the prevalence of Posttraumatic Stress Disorder (PTSD) in Wenchuan, China, over the four-year period following its 2008 earthquake, and to explore the risk factors related to current PTSD. Chi-square analysis and multivariate logistic regression analysis were used to assess PTSD morbidity and identify associated risk factors. The results indicated that the prevalence of PTSD was 58.2% at two months, 22.10% at 8 months, 19.8% at 14 months, 19.0% at 26 months, and 8.0% at about 44 months after the earthquake. Female gender, being married, low education, non-drinking, and poor self-perceived health status were significantly associated with PTSD during the early period following the earthquake. Depression was significantly associated with survivors' PTSD throughout the study period.

Keywords: Depression; PTSD; Self-perceived health status.
