Three recent papers published in the Lancet and Lancet Psychiatry show that China and India bear one-third of the global burden of mental illness, with millions of people going untreated due to a lack of resources and bias. Of these, China contributes 17% of the global burden of mental illness and India 15%. These two developing countries have a larger burden than all developed Western countries combined. Common mental disorders such as depression and anxiety account for the largest share of people with mental illness. Other disorders include substance use disorder dementia, epilepsy and others. The researchers noted that the lack of trained mental health professionals and robust mental health public services, coupled with frequent stigma, means that the proportion of people with mental illness seeking treatment is very low in China and India: less than 6 percent of people with anxiety, depression, substance abuse, dementia and epilepsy have sought treatment in China, and only 10 percent in India, which is slightly higher. In contrast, the rate in developed countries is 70 percent or higher. Another study found that in China, mental and neurological disorders and substance abuse accounted for 7 percent of the total healthy population in 1990, rising to 11 percent in 2013. Researchers predict that the situation could get worse in the next decade: by 2025, the number of people with mental illness in China could reach 36.9 million, an increase of about 10 percent from today. The researchers call on the government to increase funding for mental health care. Both countries spend less than 1 percent of their health budgets on mental health, the report notes. In the U.S., the percentage is closer to 6 percent, and in Germany and France, for example, it is as high as 10 percent. But China does not have the highest prevalence of mental illness in the world; the U.S. prevalence rate is 26.4 percent, much higher than China and India.
