Official DALY estimates had not been updated by WHO since 2004 until the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010), also known as the Global Burden of Disease Study 2010, was published in December 2012. The work quantified the burdens of 291 major causes of death and disability and 67 risk factors disaggregated by 21 geographic regions and various age–sex groups. GBD 2010 had the Institute for Health Metrics and Evaluation as its coordinating center, but was a collaboration between several institutions including WHO and the Harvard School of Public Health. The work was funded by the Gates Foundation. The GBD 2010 estimates contributed to WHO's own estimates published in 2013, although WHO did not acknowledge the GBD 2010 estimates.
