Clicking on a given disorder will take you to the relevant section for further data and information. The table here provides a summary of the data which follows on mental health and substance use disorders. Improving awareness, recognition, support and treatment for this range of disorders should therefore be an essential focus for global health. The data shown in this entry demonstrate that mental health disorders are common everywhere. It is also important to keep in mind that the uncertainty of the data on mental health is generally high so we should be cautious about interpreting changes over time and differences between countries. Figures presented in this entry should be taken as estimates of mental health disorder prevalence - they do not reflect diagnosis data (which would provide the global perspective on diagnosis, rather than actual prevalence differences), but are imputed from a combination of medical, epidemiological data, surveys and meta-regression modelling where raw data is unavailable. This is true across all countries, but particularly at lower incomes where data is scarcer, and there is less attention and treatment for mental health disorders. Mental health disorders remain widely under-reported - in our section on Data Quality & Definitions we discuss the challenges of dealing with this data. This broad definition incorporates many forms, including depression, anxiety, bipolar, eating disorders and schizophrenia. The underlying sources of the data presented in this entry apply specific definitions (which we describe in each relevant section), typically in accordance with WHO’s International Classification of Diseases (ICD-10). Mental health disorders are complex and can take many forms. This is slightly more than one in ten people globally (10.7%) Most of the estimates presented in this entry are produced by the Institute for Health Metrics and Evaluation and reported in their flagship Global Burden of Disease study.įor 2017 this study estimates that 792 million people lived with a mental health disorder. In this entry we present the latest estimates of mental health disorder prevalence and the associated disease burden.
