Investing in treatment for depression and anxiety leads to fourfold return
World Health Organization/World Bank Group press release – Depression and anxiety disorders cost the global economy US$1 trillion each year
12 April 2016, Washington DC, USA — Every US$ 1 invested in scaling up treatment for depression and anxiety leads to a return of US$ 4 in better health and ability to work, according to a new WHO-led study which estimates, for the first time, both the health and economic benefits of investing in treatment of the most common forms of mental illness globally. The study, published today in The Lancet Psychiatry, provides a strong argument for greater investment in mental health services in countries of all income levels.

“We know that treatment of depression and anxiety makes good sense for health and wellbeing; this new study confirms that it makes sound economic sense too,” said Dr Margaret Chan, Director-General of the World Health Organization (WHO). “We must now find ways to make sure that access to mental health services becomes a reality for all men, women and children, wherever they live.”

Depression and anxiety are increasing
Common mental disorders are increasing worldwide. Between 1990 and 2013, the number of people suffering from depression and/or anxiety increased by nearly 50%, from 416 million to 615 million. Close to 10% of the world’s population is affected, and mental disorders account for 30% of the global non-fatal disease burden. Humanitarian emergencies and ongoing conflict add further to the need for scale-up of treatment options. WHO estimates that, during emergencies, as many as 1 in 5 people are affected by depression and anxiety.
Returns on investment in treatment far outweigh the costs

The new study calculated treatment costs and health outcomes in 36 low-, middle- and high-income countries for the fifteen years from 2016-2030. The estimated costs of scaling up treatment, primarily psychosocial counselling and anti-depressant medication, amounted to US$ 147 billion. Yet the returns far outweigh the costs. A five percent improvement in labour force participation and productivity is valued at US$ 399 billion, and improved health adds another US$ 310 billion in returns.

However, current investment in mental health services is far lower than what is needed. According to WHO’s Mental Health Atlas 2014 survey, governments spend on average 3% of their health budgets on mental health, ranging from less than 1% in low-income countries to 5% in high-income countries.

“Despite hundreds of millions of people around the world living with mental disorders, mental health has remained in the shadows,” said Jim Yong Kim, President of the World Bank Group. “This is not just a public health issue—it’s a development issue. We need to act now because the lost productivity is something the global economy simply cannot afford. ”…
