Global, regional, and national burden of suicide mortality 1990 to 2016: systematic analysis for the Global Burden of Disease Study 2016

Research

Abstract

Objectives

To use the estimates from the Global Burden of Disease Study 2016 to describe patterns of suicide mortality globally, regionally, and for 195 countries and territories by age, sex, and Socio-demographic index, and to describe temporal trends between 1990 and 2016.

Design

Systematic analysis

Main outcome measures

Crude and age standardised rates from suicide mortality and years of life lost were compared across regions and countries, and by age, sex, and Socio-demographic index (a composite measure of fertility, income, and education).

Results

The total number of deaths from suicide increased by 6.7% globally over the 27 year study period to 817 000 deaths in 2016. However, the age standardised mortality rate for suicide decreased by 32.7% worldwide between 1990 and 2016, similar to the decline in the global age standardised mortality rate of 30.6%. Suicide was the leading cause of age standardised years of life lost in the Global Burden of Disease region of high income Asia Pacific and was among the top 10 leading causes in eastern Europe, central Europe, western Europe, central Asia, Australasia, southern Latin America, and high income North America. Rates for men were higher than for women across regions, countries, and age groups, except for the 15 to 19 age group. There was variation in the female to male ratio, with higher ratios at lower levels of Socio-demographic index. Women experienced greater decreases in mortality rates than men.

This paper has not reported the burden of suicide attributable to risk factors such as mental disorders, drug and alcohol use, or violence; further research quantifying the contribution of these and other risk factors to suicide mortality would be useful in informing interventions to prevent suicide.

Discussion

Taken as a whole, these patterns reflect a complex interplay of factors, specific to regions and nations, including sociodemographic, sociocultural, and religious factors; levels of economic development, unemployment and economic events; distribution of risk factors, such as exposure to violence or use of alcohol and drugs; choices of and access to means of suicide; and patterns of mental illness and as well as culturally specific relations with suicide.

Conclusions

Age standardised mortality rates for suicide have greatly reduced since 1990, but suicide remains an important contributor to mortality worldwide. Suicide mortality was variable across locations, between sexes, and between age groups. Suicide prevention strategies can be targeted towards vulnerable populations if they are informed by variations in mortality rates.

Although the decrease in suicide mortality has been substantial during the period 1990 to 2016, if current trends continue, only 3% of 118 countries will attain the Sustainable Development Goals target to reduce suicide mortality by one third between 2015 and 2030.
