Objective:To describe the prevalence of major depressive disorder( MDD) and distribution in Chifeng City,and explore related risk factors.Methods:Totally 6376 individuals aged 18 years and over were sampled by using stratified Probability-Proportional-to-Size sampling in Chifeng City.All respondents were interviewed by trained interviewers face-to-face.The Composite International Diagnostic Interview-3.0 Computer Assisted Personal Interview( CIDI-3.0-CAPI) was used to diagnose major depressive disorder by the criteria and definition of the fourth edition of Diagnostic and Statistical Manual of Mental Disorders of American Psychiatric Association.Results:Totally 4528 respondents were interviewed by using CIDI-3.0-CAPI.The weighted lifetime and 12-month prevalence of MDD were 4.38% and 1.71%,respectively.The 12-month prevalence rate of MDD was higher in females than in males( 2.11% vs.1.23%,P<0.05).The rates in age group of 50-64 years and age group of 65 years and over were significantly higher than that in age group of 18-34 years( 2.72%vs.0.92%,P<0.01;2.65%vs.0.92%,P<0.05).The median onset age of MDD was 40( 4,80) years.It was found that only 2.4% of the patients with MDD reported to seek help from psychiatrists.Conclusion:The prevalence of MDD is lower than the same kind survey abroad while it is close to the domestics.Women and people aged50 and over may have a higher chance of suffering MDD.Few people with MDD seek mental health professionals’ help,the reasons and countermeasures are worthy of further discussion.
