The Middle East is one of the most conflict-riven areas on the planet - but murder and suicide are actually killing far more people in the region, a major new study has found.

Murder and suicide accounted for 1.4 million deaths across 22 countries in the eastern Mediterranean, including Afghanistan, Iran, Pakistan, Somalia, Syria and Yemen, recent research published by the International Journal of Public Health (IJPH) showed.

Across the 22 countries - which have a combined population of 600 million people - the violence of war was directly responsible for another 144,000 deaths over the same period, the study containing 15 papers and three editorials said.

The data showed a 100 per cent increase in suicides and 152 per cent increase in murders over the course of 25 years, compared to a respective rise of 19 per cent and 12 per cent in the rest of the world, the study’s lead author told the AFP - a knock-on effect of the psychological scars of war.

“Intractable and endemic violence is creating a lost generation of children and young adults,” said Ali Mokdad, director for Middle Eastern Initiatives at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington.

“The future of the Middle East is grim unless we can find a way to bring stability to the region.”

The study also noted a sharp increase in mental health conditions such as depression, anxiety and bipolar disorders in the region, and a severe shortage in mental health professionals such as counsellors and psychiatrists.

In Yemen, which is suffering from a more than two-year-long war, famine and cholera outbreak and where medical infrastructure is on the brink of collapse, there are just 0.5 psychiatrists per 100,000 people, IJPH found.

The IJPH used data estimates from the most recent Global Burden of Diseases, Injuries, and Risk Factors study (GBD), which is published annually, and surveys health loss across 132 countries.
