Prevalence of hearing impairment in a community population of adults with learning disability: access to audiology and impact on behaviour

Abstract

SummaryThere is a paucity of studies exploring the frequency of problem behaviours in people with learning disability and hearing impairment. Deafness in learning disability has been described as a ‘double jeopardy‘ because the difficulties are compounded to be more than the sum of their parts. The aim of the study was to ascertain the prevalence of hearing impairment in a community population of adults with learning disability and then investigate their access to audiology. We also aimed to collect information on the prevalence of problem behaviours in this population and explore links between hearing impairment and the use of hearing aids and problem behaviours. The prevalence of hearing impairment was 9.2%, 70% had been seen by audiology services at some time in their life but only 24% had ongoing assessments and hearing‐aid maintenance. Sixty‐two percent of the population had problem behaviours and 34% had self‐injurious behaviour. The high prevalence of problem behaviours and self‐injurious behaviour found in this population compared with other studies suggests a need for further research. These findings also reveal that the hearing status of people with a learning disability continues to be overlooked as the deafness often gets lost among their other problems.
