In 2015, the World Health Organisation (WHO) identified over 800,000 reported cases of depression in Sri Lanka.

The Health Ministry’s Director of Mental Health, Dr. Chithramalee de Silva has stated that 10% of the population is affected by mental health problems, with 2% suffering from major psychiatric disorders such as severe depression, schizophrenia and bipolar disorder, and nearly 3,000 people committing suicide every year, with many more attempting suicide. Sri Lanka is 22nd in global rankings for suicides.

The most vulnerable to depression are those between 50-69 years, followed by those 70+ and then by those in the 15-49 year age group. As in other parts of the world, the prevalence of depression in Sri Lanka is higher among females.

Many studies have found that poverty and low income can push people towards depression. A study published by the Journal of Affective Disorders on Depression in Sri Lanka revealed that the lack of basic amenities and poor financial resources are strongly associated with depression among men in Sri Lanka. Studies conducted in the Northern province in Sri Lanka suggest a slightly higher prevalence of depression over other parts of the country. Additionally, 10-15% of mothers are reported to experience postpartum depression, usually in the first 3 months after child birth. Further, a study revealed that about 9% of undergraduates screened positive for major depression.
