Global Burden of Disease (GBD)
The GBD study is the largest and most comprehensive effort to quantify health loss across places and over time, so health systems can be improved and disparities eliminated.
Nominations are now open for the GBD Emerging Researcher Award!
The $5,000 award supports early-career global health researchers as they study burden of disease in populations.

About the GBD study
Everyone, all over the world, deserves to live a long life in full health. One of the largest scientific collaborations in the world, the GBD measures what prevents us from achieving that goal, putting knowledge and tools into the hands of people and groups around the world to make people healthier.
By identifying the biggest health problems, it is helping governments, scientists, and partners advocate for resources and answer questions such as:
- What diseases, injuries, and risk factors cause the most early death and disability in a given country?
- How does health performance differ across countries?
- When designing an intervention to improve the health of young women, which health problems should be targeted to make the greatest impact?

Collaboration across the scientific community is one of our core principles. From data analysis to policy use, the GBD Collaborator Network is instrumental to the GBD study and affiliated research projects.
