Abstract
PurposeHearing impairment (HI) is the most common sensory impairment and may negatively impact sleep through reduced auditory input. Factors associated with HI such as anxiety regarding communication in daily life may also adversely impact an individual's sleep. Here, research on the relationship between HI and sleep disruption was catalogued using scoping review methodology.MethodA systematic strategy was employed to search various electronic databases. This review is reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses Scoping Review Extension.ResultsSixteen records met inclusion criteria. Studies have investigated sleep in HI as a primary aim in noise-exposed workers or large surveys in older participants. Experimental and quasi-experimental studies report alterations to sleep architecture of potential neuroplastic origins. Studies reporting sleep as a secondary aim generally report poorer sleep in HI participants.ConclusionsThis scoping review has catalogued evidence that altered or negatively impacted sleep may be associated with HI. Potential confounding factors, mechanisms, and considerations for future research are discussed.Supplemental Material https://doi.org/10.23641/asha.9968369
Highlights
Hearing impairment (HI) is the most common sensory impairment and may negatively impact sleep through reduced auditory input
Puretone audiometry (PTA) was performed at 250–8000 Hz, with HI defined as average threshold > 25 dB HL at 1–4 kHz
Lim et al (2017) aimed to investigate the association between HI and insomnia in a sample of 809 noise-exposed male workers. They reported that PTA thresholds at 1–2 kHz in the right ear and 1 kHz were considerably higher among workers with insomnia
Summary
Hearing impairment (HI) is the most common sensory impairment and may negatively impact sleep through reduced auditory input. Factors associated with HI such as anxiety regarding communication in daily life may adversely impact an individual’s sleep. Research on the relationship between HI and sleep disruption was catalogued using scoping review methodology. Method: A systematic strategy was employed to search various electronic databases.
