This study analyzed the overall trends in domestic research related to the difficulties in feeding behavior and nutrient intake caused by the characteristics of disabilities in individuals with developmental disabilities, as well as the health issues associated with them. For this purpose, this study followed the PRISMA Flow Diagram process to select 18 domestic papers published after 2000 that directly relate to the feeding behavior and nutrient intake of individuals with developmental disabilities. Among the selected literature, 11 papers were subjected to in-depth analysis, allowing for a detailed literature review by the researchers. The analysis results are as follows: There is a need for diversification of research topics and an increase in the scope of research targeting the development of health enhancement programs through appropriate feeding behavior and nutrient intake. Furthermore, there is a necessity for the activation of research that meets practical needs in the field and continuous expansion of research targeting support for feeding behavior and nutrient intake. Furthermore, it was concluded that diversification of research methods is necessary for a deeper understanding of the research results. The findings of this study suggest that the results should serve as foundational data for the development of education and programs aimed at promoting healthy feeding behavior and nutrient intake among individuals with developmental disabilities. Moreover, they should contribute to the formulation of relevant policies.
