The epidemiological research on mental health in China has undergone decades of development, transitioning from multi-regional surveys to nationally representative studies. In 1982, Academician Shen Yucun led a team to complete the first national survey in 12 regions, revealing a point prevalence rate of 10.54‰. In 1993, the point prevalence rate in the second national survey in 7 regions rose to 11.18‰. In 2002, the Composite International Diagnostic Interview (CIDI)-3.0 and Diagnostic and Statistical Manual of Mental Disorders, Fouth Edition (DSM-Ⅳ) standards were first applied in the surveys in urban Beijing and Shanghai to achieve international standards, but the representativeness of urban samples was limited. Subsequent regional studies contributed methodological insights toward a nationally representative survey. From 2013 to 2015, a research team led by Professor Huang Yueqin, in collaboration with 43 institutions, completed the China Mental Health Survey (CMHS), covering 32 552 community adults in 157 counties/districts in 31 provinces/autonomous. This study represents the first nationally representative epidemiological survey of mental disorders in China. The main results showed that the lifetime prevalence of mental disorders among adults in Chinese communities with depressive disorders was 16.6%, including 7.4% for mood disorders and 7.6% for anxiety disorders. Only 9.5% of patients with depressive disorders received treatment, and the full treatment rate was as low as 0.5%. Further surveys based on the CMHS framework in regions such as Ningxia, Urumqi, and Inner Mongolia confirmed the high risk of disease among rural women in western China and the widespread phenomenon of inadequate treatment. The results of CMHS methodology was transformed into the national Guidelines and Technical Standards for Epidemiological Investigation of Community Mental Disorders (2015 Edition) and software copyright, and the main data had been published in The Lancet Psychiatry. It has been used to guide the formulation of policies such as the Healthy China Action (2019-2030). CMHS establishing a complete process from scientific investigation to policy translation, filling the data gap at the national level, providing a replicable paradigm for the world, especially for developing countries, and marking a new stage of evidence-based decision-making in China's mental health epidemiological research.

BACKGROUND: Epidemic thunderstorm asthma (ETSA) severely affected Melbourne, Australia in November 2016. There is scant literature on the natural history of individuals affected by ETSA. OBJECTIVE: A multicentre 12-month prospective observational study was conducted assessing symptomatology and behaviors of ETSA-affected individuals. METHODS: We used a structured phone questionnaire to assess asthma symptom frequency, inhaled preventer use, asthma action plan ownership and healthcare utilization over 12 months since the ETSA. Analysis of results included subgroup analyses of the “current,” “past,” “probable,“ and “no asthma” subgroups defined according to their original 2016 survey responses. RESULTS: Four hundred forty-two questionnaires were analyzed. Eighty percent of individuals reported ongoing asthma symptoms at follow-up, of which 28% were affected by asthma symptoms at least once a week. Risk of persistent asthma symptoms was significantly higher in those with prior asthma diagnosis, current asthma, and probable undiagnosed asthma (all p < 0.01). Of 442 respondents, 53% were prescribed inhaled preventers, of which 51% were adherent at least 5 days a week. Forty-two percent had a written asthma action plan and 16% had sought urgent medical attention for asthma in the preceding year. CONCLUSIONS: Following an episode of ETSA, patients experience a pivotal change in asthma trajectory with both loss of asthma control and persistence of de novo asthma. Suboptimal rates of inhaled preventer adherence and asthma action plan ownership may contribute to asthma exacerbation risk and susceptibility to future ETSA episodes. Longer-term follow-up is needed to determine the extent and severity of this apparent change.

BACKGROUND: A considerable portion of patients in primary care are thought to have mental disorders in Korea. But they are not easily noticed and are thus underdiagnosed and approached improperly. This study was done to assess the prevalence of common mental disorders in a hospital-based family practice and to evaluate the utility of a diagnostic tool, the Patient Health Questionnaire (PHQ). METHODS: Ten or more patients each day were systematically selected in family practice clinics for two weeks in a university and a community hospital-based family practice clinics in Seoul, Korea. Routine care was delivered as a control during the first week and the PHQ was administered to patients during the second week and the physicians were allowed to review the PHQ just before making clinical decisions. Physicians were asked to answer whether they recognized patients' with mental disorders before reviewing the PHQ. RESULTS: The prevalence of mental disorders was higher in the test group than the control except for eating disorders and other anxiety disorders (P <0.05)(test vs. control group): major depressive disorders 1.75% vs. 3.8%, other depressive disorders 6.8% vs. 11.4%, panic disorders 0.6% vs. 2.3, somatoform disorders 3% vs. 5%, alcohol abuse 2.2% vs. 8.7%, and any mental disorders 20.9% vs. 29.4%. In the test group, the percentage (95% confidence interval in parenthesis) of newly diagnosed mental disorders after physicians' review of the PHQ were 66% (49~82) in major depressive disorders, 70% (50~90) in panic disorders, 70% (56~83) in somatoform disorders, 84% (75~92) in alcohol abuse, and 68% (62~74) in any mental disorders. Patients' response to the PHQ was overall very receptive. CONCLUSION: One-week prevalence of common mental disorders in the hospital-based family practice was 29.4% and the PHQ tool was efficient to help the family physicians recognize hidden mental disorders.

BACKGROUND: Alternative medicine is defined as a non-orthodox therapeutic practices including chiropractic, acupunture, herbal medicine, faith, spiritual therapy or as all sorts of medical care that do not follow the medical community standards. Patients do not think of modern medicine as the absolute solution to their health problems and they will sometimes ask for complementary therapy and in want of referral to alternative practitioner. We have investigated the primary physicians' attitude and behavior towards alternative medicine. METHODS: Randomly selected 770 practitioners, in primary care practice in Seoul, were questioned from July to September in 1996 about the attitude to wards alternative medicine, the reasons and symptoms when referring, and experience in alternative medicine practice. RESULTS: 150 questionnaires were returned and among them 139 completed ones (18.1%) were analyzed. Among 770 doctors, 35 (25.2%) have referred patients to alternative practitioner before and more referrals were made when they worked together closely or had some prior training. The belief of special effect of alternative medicine on certain disease was the first reason to refer. Other reasons were for herbal medicine, acupunture, and chiropractice in the order of seguence. The standard way to learn alternative medicine was to attend seminars available through certain institutions. On referral either chronic pain or musculoskeletal disease were the most chief complaints or main diseases of patients. 15 doctors (10.8% ) had some experience in practicing an alternative approach and the patient subjeccts were more likely to be women, and there was increased tendency to be working with another doctor, and to have been trained for such practice. The items used by alternative practitioners were acupunture, herbs in the order of seguence. CONCLUSIONS: Alternative medicine is accepted somewhat by primary physicians in Seoul although the rate of referral and practice is lower than 54% compared to 16% in Canada.
