The Global Burden of Disease 2010 (GBD2010) Study reported that mental and substance use disorders were responsible for 184 million disability-adjusted life years (DALYs) worldwide in 2010 and were the leading cause of disability, in terms of years of life-lived with disability (YLDs) (Whiteford et al, 2013: http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(13)61611-6/fulltext).
Whilst these estimates were based on the best available epidemiological data, there were substantial gaps in the available information (see Baxter et al, 2013: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0065514) particularly for populations in Central and Eastern Europe, and many parts of Asia and Sub-Saharan Africa.
Lack of information resulted in considerable uncertainty around population burden estimates.
Prof Whiteford's team are currently revising these burden estimates for the next GBD report and are seeking epidemiological data to inform new calculations.
If you or your group have data for mental or illicit substance use disorders for your country we encourage you to contact Harvey Whiteford (firstname.lastname@example.org) or Amanda Baxter (email@example.com).
Disorders and inclusion criteria for GBD 2013 will be posted on the Burden of Disease section of the QCMHR website (http://qcmhr.uq.edu.au/research/policy-and-epidemiology/peabod/burden-of-disease/)
