Childhood disability is now a global health priority under the Sustainable Development Goals (SDGs). This study clarifies developmental milestones and the burden of developmental disabilities in young children.
Area of Science:
- Global Health
- Developmental Pediatrics
- Public Health Policy
Background:
- Childhood disability was overlooked in global health before the 2015 Sustainable Development Goals (SDGs).
- The SDGs mandate identification and support for children under 5 at risk of developmental delays.
- Current tools, like UNICEF's, have limitations in detecting disabilities.
Purpose of the Study:
- To identify conditions associated with developmental disabilities using International Classification of Diseases (ICD) codes.
- To define "developmentally on track" for children with developmental disabilities and delays.
- To summarize the global burden of developmental disabilities in children under 5 and highlight the role of caregivers.
Main Methods:
- Analysis of International Classification of Diseases (ICD) codes for common developmental disability conditions.
- Review of diagnostic and functional approaches for measuring population-level disabilities.
- Synthesis of global evidence on the burden of developmental disabilities.
Main Results:
- Developmental disabilities were clarified in relation to ICD codes and "developmentally on track" concepts.
- The global burden of developmental disabilities in children under 5 was summarized.
- The importance of pediatric caregivers in supporting children with developmental disabilities was highlighted.
Conclusions:
- Addressing childhood disability is crucial for achieving the SDGs.
- Improved tools and understanding are needed to identify and support children with developmental disabilities.
- Pediatric caregivers play a vital role in the care and development of these children.
