Suicide deaths have risen by 20,000 over past 30 years aroun
Suicide presents an ongoing public health challenge internationally. Nearly 800 000 people around the world lose their life to suicide every year and many more attempt suicide.

Decomposition analysis was performed using global suicide mortality and population data from the Global Burden of Disease Study 2019.

Despite a significant decrease in the age-specific suicide rate between 1990 and 2019, the overall number of suicide deaths increased by 19 897 in the same time period. The reductions in age-specific suicide rates contributed to the overall reductions in suicide rates; however, this was offset by overtime changes in population age structure.

The increase in suicide numbers was partly attributable to population growth and population age structure, which was attenuated by the significant reduction in overall suicide rates. The combined effect of these factors varied across the World Bank income level regions. For example, in the upper-middle-income level region, the effect of the reduction in age-specific suicide rates exceeded the effect of population age structure and population growth, resulting in a substantial decline in total suicide deaths.

However, in the lower-middle-income regions, there was a notable increase in suicide death, which was related to the net gain of the reduction in age-specific suicide rates and negated by the increase in the number of suicide deaths due to population growth and population age structure.

Conclusively, more support and resources should be deployed for suicide prevention in the low-income and middle-income regions in order to achieve the reduction goal. Moreover, suicide prevention among older adults is increasingly critical given the world’s rapidly aging populations in all income level regions.
