Epidemiological Survey of the Prevalence and Associated Factors of Mental Disorders in Xinjiang Uygur Autonomous Region
Abstract
Background Socioeconomic development, lifestyle changes and the COVID-19 pandemic all have an impact on people's mental and physical health, which may affect the prevalence of mental disorders. Currently, there is still no sufficient epidemiological information of mental disorders in Xinjiang. Objective To investigate the prevalence and influencing factors of common mental disorders among people aged 15 and above in northern Xinjiang, then compare the data with those of their counterparts in southern Xinjiang, and summarize the overall prevalence of common mental disorders in Xinjiang, providing a scientific basis for the formulation of corresponding mental health plans. Methods From November 2021 to July 2022, a multistage, stratified, random sampling method was used to select 3 853 residents from northern Xinjiang to attend a survey. General Demographic Questionnaire, and self-assessment scales (the 12-Item General Health Questionnaire, Mood Disorder Questionnaire, Symptom Checklist-90, etc.) and other assessment scales (Hamilton Depression Inventory, Bech-Rafaelsen Mania Rating Scale, Brief Psychiatric Rating Scale, etc.) were used as survey instruments. Mental disorders were diagnosed by the ICD-10 classification of mental and behavioral disorders by two psychiatrists with at least five years' working experience, or by a chief or associate chief psychiatrist when there is an inconsistency between the diagnoses made by the two psychiatrists. Results The point prevalence rate and age-adjusted rate of common mental disorders in northern Xinjiang were 9.71% (374/3 853) and 10.07%, respectively. The point prevalence rate and age-adjusted rate of common mental disorders in the whole Xinjiang were 9.69% (750/7 736) and 9.90%, respectively. The point prevalence rates of mood disorders, anxiety disorders, schizophrenia, organic mental disorders, and mental retardation in northern Xinjiang were 4.83% (374/7 736), 3.63% (281/7 736), 0.63% (49/7 736), 0.23% (18/7 736), and 0.36% (28/7 736), respectively. Multivariate Logistic regression analysis for northern Xinjiang showed that: the risk of mood disorders in females was 1.854 times higher than that in males〔95%CI (1.325, 2.593) 〕; The risk of mood disorders increased by 5.210 times in 25-34-year-olds〔95%CI (1.348, 20.143) 〕 and 3.863 times in 35-44-year-olds 〔95%CI (1.030, 14.485) 〕 compared with that in those aged ≥65 years; The risk of mood disorders increased by 0.199 times in those with high school or technical secondary school education〔95%CI (0.078, 0.509) 〕 and 0.147 times in those with two- or three-year college and above education〔95%CI (0.056, 0.388) 〕 compared with that in illiteracies. The risk of anxiety disorder in females was 1.627 times higher than that in males〔95%CI (1.144, 2.315) 〕; The risk of anxiety disorder increased by 0.257 times in 15-24-year-olds〔95%CI (0.091, 0.729) 〕, 0.243 times in 45-54-year-olds〔95%CI (0.101, 0.583) 〕, and 0.210 times in 55-64-year-olds〔95%CI (0.067, 0.661) 〕 compared to that of those aged ≥65 years old. The risk of schizophrenia among people living in villages or towns was 4.762 times higher than that of those living in cities〔95%CI (1.705, 13.300) 〕; The risk of schizophrenia among people with high school or technical secondary school education was 0.079 times higher than that of illiteracies〔95%CI (0.015, 0.405) 〕. Conclusion The prevalence of mood disorders and anxiety disorders is high among all types of mental disorders in Xinjiang. Females, rural people, or low educated people in northern Xinjiang are more prone to various types of mental disorders.
