Suicide rates in the world: 1950-2004

Area of Science:

• Epidemiology
• Public Health
• Global Health

Background:

• Suicide rates exhibit significant global disparities.
• Understanding the drivers of these variations is crucial for public health interventions.
• Previous research indicates potential regional and developmental influences on suicide trends.

Purpose of the Study:

• To describe cross-country differences and temporal trends in suicide rates.
• To analyze the stability of suicide rates within and between countries.
• To identify the primary sources of variance in global suicide rates.

Main Methods:

• Utilized data from the World Health Organization's Mortality Database.
• Analyzed suicide rates across 71 countries spanning from 1950 to 2004.
• Employed random-effect models to assess between-country and within-country stability.

Main Results:

• Demonstrated substantial variation in suicide rates across diverse countries and regions.
• Revealed that over 90% of the variance in suicide rates stems from between-country differences.
• Indicated a strong temporal stability in suicide rates when examined globally.

Conclusions:

• Suicide rates are predominantly characterized by persistent cross-national differences.
• The findings underscore the importance of country-specific factors in understanding suicide.
• Suicide rates exhibit remarkable stability over time within individual countries.
