Suicide is the world's eighth leading cause of death. Globally, suicide takes more lives than murder and war put together, according to a World Health Organization (WHO) report.
"Since 1950 the figure has grown 60% worldwide," said Professor Boris Polozhy of the Moscow Serbsky Institute for Social and Forensic Psychiatry.
In Europe the country with the highest rate, among both men and women aged 25-64 years, is Lithuania, followed by Belarus, Russia and Latvia. The region with the lowest suicide rate is Latin America.
In Russia, the number of suicides has plunged 30% from 2001 to 2006, when a total of 42,855 Russians committed suicide. Currently, the overall rate is 30 deaths per 100,000, with over 22% of suicides committed by people aged 40-49. Almost six times as many Russian males commit suicide than females.
"The peak suicide rate in Russia was in 1995, and the figure is now falling," Polozhy said.
Research also shows that the most vulnerable jobs are psychiatrists, musicians, lawyers, military personnel and insurance agents.
