The Lancet & The Lancet Psychiatry: One-third of global burden of mental illness occurs in China and India, experts highlight need for action

The Lancet

  • Burden of mental illness in China and India higher than all high-income countries combined
  • Community engagement and collaboration with traditional and alternative medicine practitioners key to bridging mental health treatment gap

A third of the global burden of disease for mental, neurological and substance use disorders occurs in India and China - more than in all high-income countries combined - yet most people with mental disorders in these countries do not receive needed treatment.

Three new papers, published today in The Lancet and The Lancet Psychiatry, mark the launch of the China-India Mental Health Alliance, a long-term project bringing together experts from China and India to look at the current status of mental health and mental health services in both countries.

The authors shed light on the vast mental health treatment gap in China and India, and say that community engagement, increased support for community health workers and collaboration with traditional and alternative medicine practitioners are key to providing more accessible, affordable, and acceptable mental health care in India and China.

With a combined population of over 2.5 billion, China and India make up 38% of the world population. The aim of the Alliance is to identify evidence-based solutions to their shared problems. These three papers are the first of several publications to be released over the coming year.

Burden of mental illness in China and India (paper 1)

New analysis by the Alliance of Global Burden of Disease data [1] reveals that:

  • The burden of mental illness will increase more rapidly in India than in China over the next ten years. In 2013, 36 million years of healthy life were lost to mental illness in China, and 31 million in India. Estimates suggest that by 2025, 39.6 million years of healthy life will be lost to mental illness in China (10% increase), and 38.1 million in India (23% increase).
  • In both countries, substance use disorders were more common in men than women - the burden of drug dependence disorders was more than twice as high for men as women, and the burden of alcohol use disorders was nearly seven times higher for men as women (GBD, table 2).
  • Dementia is a growing problem for both countries. From 2015 to 2025, it is estimated that the number of healthy years lost due to dementia will increase by 82% in India (from 1.7 million to 3.2 million) and by 56% in China (from 3.5 million to 5.4 million).

Mental health treatment gap (paper 2)

  • In China, less than 6% of people with common mental health disorders (mood or anxiety disorders), substance use disorders, dementia and epilepsy seek treatment. Among people with psychotic disorders, 40% have never sought treatment from mental health professionals.
  • In India, only about 1 in 10 people with mental health disorders are thought to receive evidence-based treatments.

Both countries have very few trained mental health professionals, poor access to mental health services (especially in rural areas), low investment, and high levels of stigma which may prevent people from accessing services. Less than 1% of the national healthcare budget in either country is allocated to mental health care.

Integration of traditional and alternative medicine (paper 3)

At the same time, both countries have large numbers of traditional, complementary and alternative practitioners - such as yoga practitioners in India and Traditional Chinese Medicine practitioners in China - whose clients include many individuals with mental health problems. People use alternative medicine for a number of reasons including faith, culture, cost and a belief they are safer, and the authors say that more research is needed to fully understand the effectiveness and potential risks of these therapies.

Since the medical system cannot address the mental health treatment gap alone, the authors suggest that traditional medicine practitioners could be trained to recognise and refer patients who pose a risk to themselves and others, or to advise patients against stopping their medication. Mental health experts could, in turn, promote the values of traditional healers - for instance by advising on the effectiveness of different forms of therapy that recognise cultural ideas about distress, and facilitate social support through things like diet or exercise.

Professor Vikram Patel, from Public Health Foundation of India, India and the London School of Hygiene & Tropical Medicine, London, UK says: "While India has progressive policies regarding mental health care, the actual implementation of comprehensive community oriented services is patchy and the treatment gaps, especially in rural areas, are very large. Innovators have shown how these gaps might be reduced, for example through task-sharing with front-line workers and engagement of the community. These are the models of care which deserve public financing for scaling up. Additionally, we must explore how alternative medicine practitioners can work in collaboration with medical doctors to improve the lives of people living with mental health problems." [2]

Professor Michael Phillips, Shanghai Jiao Tong University, China, and Emory University, Atlanta, USA says: "The passage of China's first national mental health law in 2012 was the culmination of 30 years of effort to bring the huge public health problem of mental illnesses out of the shadows. As is true for many national mental health laws, the current challenge is mobilizing the resources and sustained political will needed to fully implement the many progressive objectives outlined in the law. There has been a concerted national effort to identify and provide free treatment to the large numbers of individuals with psychotic illnesses who remain unidentified and untreated, but lack of mental health manpower in rural areas is limiting the effectiveness of this effort. Other mental health conditions remain untreated or under-treated: very few Chinese with common mental illnesses such as depression and anxiety ever seek treatment; the health system has not yet taken the problem of alcohol abuse -primarily a male problem in China - seriously; and the country as a whole is ill-prepared for the coming epidemic of dementia as the population ages rapidly. Addressing these complex problems will require increased governmental support for multi-disciplinary longitudinal initiatives that assess the effectiveness and feasibility of novel community-based approaches to providing both services and social support for persons affected by mental health conditions."

The China-India Mental Health Alliance is jointly coordinated by the Shanghai Mental Health Center at the Shanghai Jiao Tong University in China and the Public Health Foundation of India.

[1] Data from the Global Burden of Disease (GBD) study 2013. GBD methodology employs the disability-adjusted life year (DALY) as a summary metric of population health loss, reflecting years of healthy life lost due to morbidity and mortality. The DALY is the sum of years of life lost due to premature mortality (YLLs) and years lived with disability (YLDs). DALYs reflect only 'health loss' and not the broader impact on the individual and on the family, economy, and society (e.g., social inequity and social burden). Mental health, neurological and substance use disorders (MNS) include schizophrenia, bipolar disorder, depressive and anxiety disorders, attention deficit hyper-activity disorder (ADHD), conduct disorder, autism spectrum disorders, idiopathic intellectual disorders, alcohol and illicit drug use disorders, dementia and epilepsy.
