Prevalence and Risk Factors of Major Depression Disorders in Local Teachers Three Months after Lushan Earthquake

Objective To determine the prevalence and risk factors of major depression disorder (MDD） in local teachers at an early stage post Lushan earthquake. Methods A prospective cohort study was undertaken, with 319 local teachers receiving diagnostic MDD assessment using MINI 14-22 d and 85-95 d after the earthquake, respectively. Possible predictive factors were identified using a self-developed questionnaire. Univariate and multivariate logistic regression analyses were performed to determine the predictors of MDD. Results Fifteen (4.70%) local teachers were diagnosed with MDD. Those who had an injured direct relative 〔odds ratio (OR)=6.26)〕, with inhabitable house (OR=4.26), and felt easy to get sad 14-20 d weeks post earthquake (OR=11.45) were more likely to suffer from MDD than others. An anxious emotion 14-20 d post earthquake was a protective factor (OR=0.14) of MDD. Conclusion Post earthquake MDD in local teachers deserves concerns, especially for those who have injured relatives, with an inhabitable house, and who feel easy to get sad 14-20 d post earthquake.
