Questionnaires pertaining to anxiety disorder indicated by the Zung Self-Rating Anxiety Scale (SAS) and demographic characteristics, health status, lifestyle factors, work conditions and work-related psychological status were distributed to all registered doctors during April-June 2009. There were 1,134 effective respondents (effective response rate 71.2%), and these respondents became our subjects (539 male doctors and 595 female doctors). Results: The average standard scores of SAS for the male and female doctors were 46.8 and 46.7. General linear model analysis indicated that SAS was associated with, in standardized estimate (β) sequence, cynicism, emotional exhaustion, professional efficacy, sleeping problem, chronic diseases and physical exercise in men and with professional efficacy, emotional exhaustion, cynicism, sleeping problem, chronic diseases, job satisfaction, alcohol consumption and meals in women. Work-related psychological status contributed the most to the model R-square.
