Reducing pesticide self-poisonings is one of the most effective ways to reduce suicide deaths –the second leading cause of death among young people aged 15-29 years, after road injury, according to a new WHO report.

Release of the WHO report, Preventing suicide, a resource for pesticide registrars and regulators, coincided with World Suicide Prevention Day on Tuesday.

The report reflects the growing body of evidence that regulations to prohibit the use of highly hazardous pesticides can lead to reductions in national suicide rates. In Sri Lanka, a series of bans led to a 70% fall in suicides and an estimated 93 000 lives saved between 1995 and 2015. In the Republic of Korea – where the herbicide paraquat accounted for the majority of pesticide suicide deaths in the 2000s – a ban on paraquat in 2011-2012 was followed by a halving of suicide deaths from pesticide poisoning between 2011 and 2013.

Globally, there is one suicide death every 40 seconds. While 79% of the world’s suicides occurred in low- and middle-income countries, high-income countries have the highest rate, at 11.5 per 100 000, according to a WHO press release.

Globally, there are an estimated 10.5 deaths by suicide per 100 000 people a year. Rates varied widely, however, between countries, from 5 suicide deaths per 100 000, to more than 30 per 100 000. Nearly three times as many men as women die by suicide in high-income countries, in contrast to low- and middle-income countries, where the rate is more equal.
