Intellectual developmental disability (IDD) has progressively been a raised concern. This study aimed to comprehensively analyze the global burden, regional and age-specific differences, temporal trends, and economic cost of IDD attributable to CHD.\nMethods: This study was a secondary analysis of the Global Burden of Disease Study 2021 and World Development Indicators. The burden of IDD attributable to CHD was evaluated with prevalence, disability-adjusted life years, and estimated annual percentage change across global, socioeconomic, geographic, and age-specific subgroups. Joinpoint regression models were used to describe the temporal trends. Economic cost models were developed to estimate both direct and indirect costs.\nResults: In 2021, an estimated 1.05 million people lived with IDD attributable to CHD worldwide. Low-middle social-demographic index (SDI) regions were mostly affected. South Asia experienced the highest prevalence (0.30 million) among all geographic subregions. Children under the age of five were more susceptible to IDD attributable to CHD. The temporal trends varied across different SDI regions and age subgroups. The health-related expenditure of direct costs was disproportional with the burden of IDD attributable to CHD, which also contributed to a substantial income loss in the future.\nConclusions and Policy Implications: Socioeconomic disadvantage and younger age are associated with a higher burden of IDD attributable to CHD. Efforts for both reducing CHD mortality and improving neurodevelopmental outcomes should be coordinately allocated.<\/jats:p>","DOI":"10.5334\/gh.1511","type":"journal-article","created":{"date-parts":[[2026,1,16]],"date-time":"2026-01-16T10:41:06Z","timestamp":1768560066000},"page":"2","source":"Crossref","is-referenced-by-count":0,"title":["Disease
