The number of countries with national suicide prevention strategies has increased in the five years since the publication of World Health Organisation’s (WHO) first global report on suicide, said the WHO in the lead-up to World Suicide Prevention Day on 10 September 2019. But the total number of countries with strategies, at just 38, is still far too few and governments need to commit to establishing them.
“Despite progress, one person still dies every 40 seconds from suicide,” said WHO Director-General, Dr Tedros Adhanom Ghebreyesus. “Every death is a tragedy for family, friends and colleagues. Yet suicides are preventable. We call on all countries to incorporate proven suicide prevention strategies into national health and education programmes in a sustainable way.”
Second leading cause of death among young people
The global age-standardised suicide rate for 2016 was 10.5 per 100,000. Rates varied widely, however, between countries, from 5 suicide deaths per 100,000, to more than 30 per 100,000. While 79% of the world’s suicides occurred in low- and middle-income countries, high-income countries had the highest rate, at 11.5 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.
Suicide was the second leading cause of death among young people aged 15-29 years, after road injury. Among teenagers aged 15-19 years, suicide was the second leading cause of death among girls (after maternal conditions) and the third leading cause of death in boys (after road injury and interpersonal violence).
The most common methods of suicide are hanging, pesticide self-poisoning, and firearms. Key interventions that have shown success in reducing suicides are restricting access to means; educating the media on responsible reporting of suicide; implementing programmes among young people to build life skills that enable them to cope with life stresses; and early identification, management and follow-up of people at risk of suicide.
Pesticide regulation: an under-used but highly effective strategy
The intervention that has the most imminent potential to bring down the number of suicides is restricting access to pesticides that are used for self-poisoning. The high toxicity of many pesticides means that such suicide attempts often lead to death, particularly in situations where there is no antidote or where there are no medical facilities nearby.
As indicated by the WHO, there is now a growing body of international evidence indicating that regulations to prohibit the use of highly hazardous pesticides can lead to reductions in national suicide rates. The best-studied country is Sri Lanka, where a series of bans led to a 70% fall in suicides and an estimated 93,000 lives saved between 1995 and 2015.
Data quality needs to improve
The timely registration and regular monitoring of suicide at the national level are the foundation of effective national suicide prevention strategies. Yet, only 80 of the 183 WHO Member States for which estimates were produced in 2016 had good quality vital registration data. Most of the countries without such data were low- and middle-income. Better surveillance will enable more effective suicide prevention strategies and more accurate reporting of progress towards global goals.
