It is estimated that about one in six children aged 3 to 7 have one or more developmental disabilities (DD) in the United States. These conditions can include ADHD, cerebral palsy, Autism spectrum disorder, vision impairment, hearing loss, learning/intellectual disabilities, and other developmental delays. Many children with developmental disabilities are also at a higher risk of being undernourished or lacking nutrition. Inadequate nutrient intake, feeding problems/disorders, and motor dysfunctions associated with DD are often related to poor nutritional status. However, there are many other social factors, that are often overlooked, which can contribute to the overall poor nutritional status of children with developmental disabilities. This thesis aimed to take a holistic look at the physical, environmental, and social determinants of health that affect the nutritional status and mealtime success of children with developmental disabilities using an intersectional approach. The research also includes a synthesis of interviews collected from parents of children with DD, social workers, occupational therapists, and speech and language therapists in order to survey what challenges children with developmental disabilities face during mealtime, nutritional challenges from parents/professionals, and assessment of nutritional programs available in the community.
