Background

Schizophrenia is a severe psychiatric illness that contributed to an estimated 12.66 million disability-adjusted life years (DALYs) lost across 20 million global cases according to the 2017 Global Burden of Disease study [1, 2]. In low- and middle-income countries, schizophrenia is ranked the 3rd leading cause of DALYs, accounting for over 15 million DALYs [3]. In China, relative to common mental disorders (e.g., anxiety, depression), schizophrenia in particular is marked by severe stigmatization [4] and, in rural areas especially, people with schizophrenia are especially vulnerable to high mortality and suicide rates [12]. However, despite conducting a national mental health epidemiological study from 2013 to 2015 [13], there has been no systematic effort to clarify the reasons for the persistent (and increasing) gap in urban versus rural services.

Assessment of the effect of China’s mental health reforms on urban versus rural access to care should be based on a comparison of the situation before and after instituting the reforms. This report provides a pre-reform baseline to which subsequent findings can be compared by assessing factors affecting urban versus rural access to care for schizophrenia – one of the mental disorders most likely to be treated– based on data from a large (n = 63,004) representative mental health epidemiological study in China conducted from 2001 to 2005 [14]. The findings support that individuals with psychotic disorders overall are more likely to seek treatment (12%) compared to other diagnostic groups including mood, anxiety, and substance use disorders (4.9, 3.2%. 0.8%, respectively) [14]. Individuals with severe psychotic disorders are even more likely to seek treatment (63.5%) compared to severe mood, anxiety, and substance use disorders (6.7, 8.5, 2.8%) [14]. The authors posit numerous factors that contribute to low treatment seeking in non-psychotic disorders in China including low awareness that the illness is treatable or perceived ineffectiveness of treatment, fear of stigmatization, and lack of access to treatment [14]. Importantly, there are notable differences in treatment rates for schizophrenia between urban and rural locales in China; in rural China, data to date indicates that cases are significantly more likely to be untreated (35.4%) compared to their urban counterparts (17.5%) [54];) that could precipitate care-seeking.

Conclusions

These results for China in 2001 to 2005 provide a snapshot of an evolving mental health service network that can be used to assess the effects on mental health services of subsequent rapid urbanization and major changes resulting from important mental health policy initiatives such as China’s 2012 national mental health law [9]. Distinguishing the independent effects of economic development, migration to cities, improvements in public health, and mental health policy initiatives on national mental health will be difficult, and the effects of these factors probably differ in different parts of the country. However, in the absence of a baseline against which current conditions can be compared, this difficult task will be rendered nearly impossible. A clear understanding of the current trajectory of mental health services and of the factors that affect this trajectory is essential to develo**, evaluating, and regularly revising effective mental health policies and programs.

These findings may also be relevant for other LMIC that are planning to implement community-based mental health reforms. Such projects need to be preceded by community-specific situation analyses that compare the urban versus rural characteristics and treatment of mental illnesses. The subsequent reforms should be flexible enough to include community- and cohort-specific adaptations that will effectively decrease disparities in the provision of mental health services between urban and rural communities. Such situation analyses should – based on our findings – include assessment of the potential differential effect of family-level factors and illness-severity factors on care-seeking for schizophrenia (and other mental disorders) in urban and rural communities. Clarification of the factors that drive the utilization of services in different subgroups of the population will help facilitate community-specific scale-up efforts to alleviate the global burden of mental disorders [33].
