Prevalence of Dysphagia in People With Intellectual Disability: A Systematic Review.
Clients with severe ID, CP, or motor issues likely have hidden swallowing trouble—screen and refer early.
01Research in Context
What this study did
The team hunted every paper that counted dysphagia in people with intellectual disability.
They found 20 studies and pooled the numbers.
Most reports came from schools, clinics, and group homes in many countries.
What they found
Swallowing trouble showed up again and again.
Risk was highest in clients with severe ID, cerebral palsy, or poor motor control.
Exact rates stayed fuzzy because each study used different yardsticks.
How this fits with other research
Pierce et al. (1994) built a quick behavioral test for feeding issues in the same group.
Their tool can flag who needs the medical checks that Robertson et al. (2017) say are missing.
Lin et al. (2005) asked directors what health care gaps worry them.
Directors listed many needs, but swallowing was not one—an apparent contradiction that shows silent problems stay off the radar.
Bigby et al. (2009) later charted reflux drugs with no clear reason, hinting that GI signs are already being missed.
Why it matters
If you serve clients with severe ID, CP, or weak motor skills, add a two-minute swallow scan to your intake. Watch for cough, wet voice, slow chewing, or food refusal. Spot red flags early and refer to speech-language pathology before pneumonia or weight loss strike.

03Original abstract
Dysphagia (feeding and swallowing disorder) is associated with serious health complications and psychosocial sequelae. This review summarizes international research relating to the prevalence of dysphagia in people with intellectual disability. Studies published from 1990 to July 2016 were identified using Medline, Cinahl, PsycINFO, Web of Science, email requests, and cross-citations. Twenty studies were identified. Dysphagia in people with intellectual disability appears to be associated with more severe levels of intellectual disability, comorbid cerebral palsy, and motor impairments. However, further research with representative samples of people with intellectual disability using adequate methods of assessment are required in order to provide more precise prevalence estimates and clarify factors that may be associated with dysphagia in this population.
