Background: While research has led to significant advancements in the health and life expectancy of children with Down Syndrome (DS), there remains a significant burden of disease and health inequity. Further research, focused on areas of greatest need, is imperative to address this. An understanding of what research has been undertaken, and any existing gaps, helps to guide future academic efforts.
Methods: We utilised an epistemological approach to summarise two decades of paediatric DS literature. Publications were categorised according to the country of origin, methodology, primary health themes and subcategory research themes.
Results: Across 5,800 paediatric DS publications we demonstrate a general increase in the number of publications in this field between 2000 and 2014, with a trending decline thereafter. The majority of publications were affiliated with Institutions based in Western countries. The majority of studies utilised a cross-sectional methodology (33.3%), while relatively few were interventional (5.6%), qualitative (2.7%) or mixed-method studies (1.6%). Most publications focused on development & cognition (13.1%), neurology (9.9%) and oncology (9.8%), with fewer focusing on genitourinary health (0.9%), growth (0.9%), mortality (0.9%) and child protection (0.2%).
Conclusion: These findings highlight areas of relative paucity within the paediatric DS literature which may warrant increased academic attention.
