A Cross-sectional Survey of Disability Attributed to Mental Disorders and Service Use in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Mental disorders are strongly associated with disabilities. National survey on disability could provide a reliable basis for policymaking in care and rehabilitation of disabled persons. This study aimed to describe the disability prevalence rates attributed to mental disorders, their distribution by sociodemographic factors, and utilizations of service.</p><p><b>METHODS</b>This study is a secondary data analysis of the Second National Sample Survey on Disability in 2006. The disability and severity were assessed using the World Health Organization Disability Assessment Schedule 2.0. Mental disorders were diagnosed according to the International Statistical Classification of Diseases and Related Health Problems 10th Revision Classification of Mental and Behavioral Disorders. Using descriptive and analytic epidemiological methods, prevalence rates of disability attributed to mental disorders and service use were calculated.</p><p><b>RESULTS</b>Data of 2,526,145 respondents were analyzed. The disability prevalence rate attributed to mental disorders in China was 6.3‰, accounting for 9.9% of all disabled people. Regarding disability prevalence attributed to mental disorders, it showed that gender, residential area, marital status, education level, and economic area were related to the prevalence distributions. The proportions of mild disability were highest in the disabled people with onset age of 18-64 years, while the proportion of extremely severe disability was highest in the disabled people with onset age of 65 years and above. Only 58.6% of disabled people attributed to mental disorders used some of the services.</p><p><b>CONCLUSIONS</b>There are statistical differences of disability prevalence attributed to mental disorders by people and region in China. Service use in disabled people with mental disorders is insufficient.</p>

Distribution and Risk Factors of Disability Attributed to Personality Disorders: A National Cross-sectional Survey in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Personality disorders can lead to some disability. However, little is known about the disability prevalence and function impairments. This study aimed to describe the disability prevalence attributed to personality disorders, its distribution, impairments of daily activities and social functions, and risk factors in China.</p><p><b>METHODS</b>Using a descriptive and analytic epidemiological method, data from the Second China National Sample Survey on Disability in 2006 were analyzed. The disability prevalence attributed to personality disorders, its distribution in different people and regions, and risk factors were statistically calculated.</p><p><b>RESULTS</b>Respondents included 1,909,205 adults. The disability prevalence rate attributed to personality disorders in China was 5.9/100,000. The disability rate attributed to personality disorders of males was higher than that of females (P = 0.012), while the rate of the unemployed was higher than that of the employed (P < 0.001). Furthermore, the rates of unmarried/divorced/widowed people and the illiterate population were higher than those of married and educated people (P < 0.001). Regarding the severity of disability attributable to personality disorders, mild disability accounted for a majority or 60% of the respondents. The data showed that disability mainly impaired respondents' ability to engage in daily activities, get along with people, and participate in social situations. According to the case-control study, marriage, employment, and higher education were protective factors of disability.</p><p><b>CONCLUSIONS</b>The prevalence of disability attributed to personality disorders is low in China and always leads to mild disability. The distribution of disability attributed to personality disorders also varies in the Chinese population.</p>

Meta-analysis on the co-morbidity rate between tuberculosis and diabetes mellitus in China / 中华流行病学杂志

Objective To understand the co-morbidity rate between tuberculosis and diabetes mellitus in the mainland of China.Methods Based on the related literature regarding tuberculosis and diabetes mellitus published in China National Knowledge Infrastructure Databases (CNKI),Wangfang Databases and the Chinese Science and Technology Journal Database (VIP),PubMed and Medline in the last 13 years.Related information was extracted and the generic inverse variance model was applied to estimate the following parameters including rate of co-morbidity,differences on gender,age,results on sputum smear samples,sources and regions of the samples.Quality of the literature was evaluated through the STROBE statement and sensitivity analysis was performed to evaluate the impact of the quality.Results Twenty two papers were included for Meta-analysis,with a total sample of 56 805.The combined prevalence rate of diabetes among patients with tuberculosis was 7.20％ (95％CI:6.01％-8.39％).According to results from subgroup analysis,at α =0.05 level,the comorbidity rates among subgroups as:age 40 and above (12.18％),smear positives (11.40％),samples from the hospitals (9.67％) and from the northern regions (9.13％) were higher than the subgroups as age below 40 (2.33％),with smear negative (4.00％),samples from the community level (6.10％)and from southern region (5.94％).Conclusion The co-morbidity rate of tuberculosis and diabetes mellitus was high in mainland China,and were high among cases:at age 40 or above,with smear positive,from hospitals or from the northem region etc.
