A study by the India State-level Disease Burden Initiative, published in The Lancet Psychiatry last week, found that 197.3 million Indians (one in every seven) were suffering from mental disorders in 2017 (The Indian Express, December 24). The study describes the prevalence of mental disorders in Indian states between 1990 and 2017. The 197.3 million in 2017 included 45.7 million cases with depressive disorders and 44.9 million with anxiety disorders.
Among the disorders with the highest prevalence, idiopathic developmental intellectual disability affects most Indians, at 4.5 per cent, followed by depressive disorders (3.3), anxiety disorders (3.3) and conduct disorders (0.8). Among depressive disorders, the prevalence is the highest in Tamil Nadu (4,796 per 100,000), followed by Andhra Pradesh (4,563), Telangana (4,356), Odisha (4,159) and Kerala (3,897).
