In a sobering revelation, a new study published in The Lancet Public Health has shed light on the global burden of suicide, reporting approximately 740,000 deaths annually—equivalent to one death every 43 seconds. The comprehensive analysis, conducted by researchers at the Institute for Health Metrics and Evaluation (IHME) at the University of Washington’s School of Medicine in Seattle, offers a deep dive into suicide trends from 1990 to 2021 across various demographics and regions.
Encouraging Declines but Persistent Challenges
Despite the grim figures, the study highlights an overall decline in the global age-standardized suicide rate by nearly 40% over the past three decades. The rate dropped from approximately 15 deaths per 100,000 people in 1990 to 9 deaths per 100,000 in 2021, reflecting the effectiveness of suicide prevention and intervention efforts. Notably, the suicide rate among females declined by over 50%, while for males, the reduction was close to 34%.
China played a significant role in this improvement, with East Asia recording the highest regional decline of 66%. However, the progress has not been uniform worldwide, as some regions experienced troubling increases.
Regions with Rising Suicide Rates
Four regions reported an increase in suicide rates between 1990 and 2021:
- Central Latin America saw a 39% rise, with Mexico witnessing a staggering 123% increase in female suicide rates.
- Andean Latin America reported a 13% increase, with Ecuador leading the rise.
- Tropical Latin America experienced a 9% increase, with Paraguay topping the region’s statistics.
- High-income North America recorded a 7% increase, with the U.S. reporting a concerning 23% rise in female suicides.
Suicide’s Place Among Global Causes of Death
In 2021, suicide ranked as the 21st leading cause of death globally, surpassing HIV/AIDS. Eastern Europe, Southern sub-Saharan Africa, and Central sub-Saharan Africa reported the highest mortality rates. For men, suicide was the 19th leading cause of death, with Eastern Europe recording the highest rate, while for women, it ranked 27th, with South Asia exhibiting the highest female suicide rates.
Risk Factors and Gender Disparities
The study reaffirms well-established risk factors for suicide, including violence, sexual assault, childhood trauma, poverty, and access to lethal means such as firearms and pesticides. It also highlights a stark gender disparity—while men are more than twice as likely to die by suicide than women, women are 49% more likely to attempt it.
Every minute, four men and six women worldwide require hospitalization due to suicide attempts. The fatality rate for suicide attempts varies greatly between genders and regions. In high-income North America, for example, one in 30.7 female suicide attempts resulted in death, compared to one in 6.3 for males.
Firearm-Related Suicides
Males globally were three times more likely than females to die by suicide using firearms. The U.S. recorded the highest firearm-related suicide rates, with nearly 22,000 male suicides involving guns (55% of all male suicides) and over 3,000 female suicides (31% of all female suicides) attributed to firearms.
According to Emily Rosenblad, co-author of the study, “Men tend to choose more violent and lethal methods of suicide, such as guns, while women are more likely to choose less fatal means such as poisoning and overdosing, which have a higher survival rate.”
Shifting Age Demographics
The study also found that suicide is occurring later in life. In 1990, the average age of death by suicide was 43 years for males and 42 years for females. By 2021, these averages had increased to 47 years for both genders. The highest mean age was found in East Asia (58 years for males, 60 years for females), while Oceania reported the youngest average age (36 years for males, 34 years for females).
Moving Forward: The Need for Continued Efforts
The findings emphasize the importance of targeted suicide prevention strategies, including increasing access to mental health support, reducing stigma, and addressing socioeconomic disparities. Policymakers and healthcare professionals can use this data to refine intervention methods and tailor support systems to vulnerable populations.
“While the progress made in declining suicide rates is encouraging, it is clear that suicide continues to impact some countries and populations more than others. Removing stigma and barriers to mental health care remains critical,” said Dr. Mohsen Naghavi, the study’s senior author.
Conclusion
As suicide remains a global crisis, a collective effort from governments, communities, and mental health professionals is essential to continue the downward trend and address rising suicide rates in vulnerable regions. Suicide prevention works best when societies prioritize awareness, early intervention, and accessible mental health services.
