Abstract
In The Lancet Psychiatry, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 Mental Disorders Collaborators1 updated their global, regional, and national burden estimates to 2019. Their analysis suggests that the proportion of global disability adjusted life-years (DALYs) attributable to mental disorders is 4·9%, and that the age-standardised DALY rate has remained basically unchanged in the past 30 years, at 1566·2 DALYs per 100 000.1 The efforts involved in producing DALY estimates (collating, adjusting, pooling, and summarising global health epidemiological data into a single disease burden metric) are complex and commendable.
