Epidemiological studies investigating the prevalence of autism have increased in recent years, within the United States and abroad. However, statistics as to how many of those children may also have a comorbid hearing loss is lacking. The prevalence of school-administrator reported diagnosis of autism spectrum disorders (clinical diagnosis [DSM-IV] and/or IDEA classification) among children with hearing loss in the US was estimated from the 2009-2010 Annual Survey of Deaf and Hard of Hearing Children and Youth conducted by the Gallaudet Research Institute. Results indicate that during the 2009-2010 school year 1 in 59 children (specifically 8-year olds) with hearing loss were also receiving services for autism; considerably higher, than reported national estimates of 1 in 91 (Kogan et al. in "Pediatrics" 124(4):1-8, 2009) and 1 in 110 (CDC 2007) for hearing children. Significantly more children with profound hearing loss had a comorbid diagnosis of autism than those with milder forms of hearing loss. These results are discussed, while highlighting the need for increased awareness and research in a population that has thus far received little services or attention.
