Background: The study aimed to determine the prevalence of alcohol use, episodic heavy drinking, and alcohol dependence and their socio-demographic correlates in Beijing, China. Methods: A total of 5,926 subjects were randomly selected in Beijing and interviewed using the Composite International Diagnostic Interview (CIDI 1.0). Data on basic socio-demographic and current major medical conditions were also collected. Results: The 12-month prevalence of alcohol use and episodic heavy drinking were 32.5 and 13.8%, respectively. The 12-month and lifetime prevalence of alcohol dependence were 1.7 and 4.3%, respectively. Age above 24 years, male sex, being married and employed, low education level (junior high school, primary school or illiterate), rural residence, and having comorbid psychiatric disorders were all significantly associated with a higher likelihood of alcohol-related disorders. Only 2.4% of the subjects with alcohol dependence were receiving treatment, and a mere 1.4% had sought treatment from mental health professionals. Conclusions: Nationwide surveys are urgently needed to further explore the prevalence of alcohol-related disorders in China. [ABSTRACT FROM AUTHOR]

Abstract: Objective: This study aimed to determine the 12-month and lifetime prevalence of major depressive episode (MDE) and their socio-demographic correlates in both the urban and rural areas of Beijing, China. Methods: A total of 4767 adults were randomly selected and interviewed in Beijing using the Composite International Diagnostic Interview (CIDI 1.0). Basic socio-demographic and clinical data were collected during the interviews. Results: The overall 12-month prevalence of MDE was 3.2%; 2.8% and 3.8% for men and women, respectively. The overall lifetime prevalence of MDE was 5.3%; 4.4% and 6.3% for men and women, respectively. Being older than 25 years of age was independently associated with increased risk of MDE. Sixteen point three percent of the subjects with lifetime MDE attempted suicide while the rate of suicide attempts was only 0.2% in subjects without MDE. The percentage of subjects with MDE who received any type of treatment from medical practitioners was 33.1%; of them, only 5.4% sought help from mental health professionals. Conclusions: National epidemiologic surveys are needed to further explore the prevalence of MDE in China. The low percentage of subjects treated for MDE constitutes a major public health problem that should be urgently addressed. [Copyright &y& Elsevier]

Abstract: Background: In China, there is limited information on smoking and its socio-demographic correlates in general, and in psychiatric patients in particular. The aim of this study was to determine the prevalence of lifetime, current mild, and heavy smoking, the socio-demographic correlates of current smoking, and its relationship with psychiatric disorders in the Beijing municipality, China. Methods: A total of 5926 subjects who met the study''s entry criteria were randomly selected from the urban and rural areas of Beijing and interviewed using standardized assessment tools, including the collection of basic socio-demographic and clinical data. All subjects fully cooperated in the interviews and readily disclosed all of the information. Results: The prevalence of lifetime smoking was 35.9%; the rates for current mild and heavy smoking were 21.8% and 10.8%, respectively. An age of 24 years or above, male sex, married, divorced, separated or widowed marital status, relatively low level of education (less than college level), being employed, a relatively high monthly income (more than RMB500), rural abode, and having a psychiatric disorder were risk factors of current smoking. Both current mild and heavy smoking were significantly associated with alcohol dependence, and current heavy smoking was also associated with a history of a major depressive episode. Conclusions: The prevalence of smoking in the rural and urban areas of Beijing is unacceptably high. In addition to certain socio-demographic factors, smoking was associated with common psychiatric disorders. Nationwide surveys are warranted to further explore the prevalence of smoking in China. Effective strategies to reduce the high rate of smoking are also needed. [Copyright &y& Elsevier]

Objective: There has been no large-scale survey of suicide-related behaviours including suicidal ideations, plans and attempts in China involving both rural and urban areas and using standardized assessment tools. The aim of the present study was to determine the lifetime prevalence of suicide-related behaviour and its relationship with sociodemographic factors and psychiatric disorders in the rural and urban regions of Beijing, China. Methods: A total of 5926 subjects were randomly selected in Beijing and interviewed using the Composite International Diagnostic Interview. Basic sociodemographic and clinical data and data on suicide-related behaviour were also collected. Results: The overall lifetime prevalence estimates of suicidal ideation, plans and attempts were 2.3%, 1.4%, and 1.0%, respectively; the corresponding figures were 2.8%, 1.6%, and 1.3% in the rural sample, and 1.8%, 1.3%, and 0.9% in the urban sample. Age (>25years), female sex, unmarried status, lower education level, lower (RMB2000month-1) monthly income and presence of major medical disorders were significantly associated with increased risk of suicide-related behaviour. 36.2% of subjects with suicide-related behavior consulted a medical practitioner and 20.7% consulted a psychiatrist. Conclusions: The prevalence of lifetime suicide-related behaviour in Beijing is lower than in Western countries, but the low percentage of subjects treated for suicide-related behaviour indicates a major public health problem that should be addressed. National surveys are needed to further explore the prevalence of suicide-related behaviour in China. [ABSTRACT FROM AUTHOR]
