Dr Chen Mo publishes a journal article in the Journal of Epidemiology and Psychiatric Sciences

Dr Chen Mo, Education Research Scientist at the Centre for Research in Child Development, has published a journal article titled “Significant regional inequalities in the prevalence of intellectual disability and trends from 1990 to 2019: a systematic analysis of GBD 2019” in the journal of Epidemiology and Psychiatric Science. This article explores the variations in prevalence rates of intellectual disability (ID) from 1990 to 2019 and the related inequalities between low and high socio-demographic index (SDI) regions by using global data from 1990 to 2019 for individuals with ID from the 2019 Global Burden of Diseases study.

The results showed that there was a slightly higher prevalence among males than females, where the highest prevalence rates were found in the low-middle SDI regions, and the lowest prevalence rates were found in the high SDI regions. While an overall decrease in global prevalence rate for ID was found, relative inequalities continue to increase with lower SDI regions needing more comprehensive support services. The study also highlights the necessity for policies and interventions targeting lower SDI regions to mobilise resources that better support individuals with ID and achieve sustainable development goals proposed by the United Nations.
