To study the prevalence and distribution of mental disorders among registered and non-registered residents in Shenzhen.
An epidemiological survey on mental disorders were carried out in Shenzhen by stratified multi-stage randomized sampling method; 7134 respondents were assessed through face-to-face interview, using the WHO standardized version on World Mental Health (WMH) Survey Initiative of the Composite International Diagnostic Interview (CIDI3.1).
(1) The weighting prevalence of mental disorders was 21.87%. The prevalence of non-registered residents was significantly higher than that of the registered residents (22.34% vs. 19.99%; OR=1.15, 95%CI: 1.03-1.29; P<0.05) and the prevalence of females was significantly higher than that of males (22.68% vs. 19.67%; OR= 1.20, 95%CI: 1.07-1.34; P<0.05). The weighting prevalence of mood disorders, anxiety disorders and psychoses were 9.62%, 14.45% and 1.40%, respectively. (2) The weighting twelve-month incidence of mental disorders was 13.42%. The incidence of non-registered residents was significantly higher than that of the registered residents (13.80% vs. 11.90%; OR=1.19, 95%CI: 1.03-1.36; P<0.05). (3)The co-morbidity rate between mental disorders was 35.76%. (4)The prevalence and severity of mental disorders were associated with sex, household situation of registration, marital status, education, economic condition and occupation status.
Mental disorders have become common diseases and serious public health problem in Shenzhen, with non-registered residents and females deserve more attention.

    ABSTRACT: As one of the fastest growing cities in Pearl River Delta of southern China, Shenzhen accommodates a higher percentage and increasing number of internal migrants, mainly coming from the inland areas. The public health issues that challenge its local government include the special population structure, high incidence of infectious diseases, high prevalence of mental problems, rising chronic disease burdens, and maternal and children's health issues, although progress has been made in the past years. The health authority of Shenzhen has realized that provision of high quality equitable public health services to its residents, including migrants is of high priority, and should be supported by innovations in the health insurance system and establishment of community-based primary care networks. Making changes within the national-level health reform framework and learning from international experiences are necessary and important.

    ABSTRACT: Community psychiatric epidemiological surveys over the last five decades have revealed a dramatic increase in the prevalence of mental disorders in China. This article summarizes the main surveys and attempts to interpret the increase of prevalence from a methodological perspective. Regional and national surveys conducted in China during 1960-1990 focused on severe mental disorders and revealed very low and stable rates of disorders. By contrast, those performed in the last decade, whether psychiatrists or lay interviewers were used, have shown much higher and more 'reliable' rates comparable to those found in high-income countries. This is especially so for depression and anxiety disorders. Given the sociopolitical turmoil that had previously plagued people in China, the dramatic rise in prevalence estimates of mental disorders in recent years cannot be simply interpreted as a substantive deterioration of mental health following rapid social change. Global and local factors that shape research methodology aimed at showing that mental disorders are common may play an important role in the dramatic increase. Future research in China should move beyond descriptive epidemiology. It should also address policy relevant issues in view of the limited resources available for mental health interventions.
