Association between hearing loss and deprivation among Welsh adults: a cross-sectional observational study

ObjectiveTo index levels of hearing loss with respect to area-level indices of deprivation in a Welsh population.DesignA cross-sectional observational study of all adults (aged >18) that attended Abertawe Bro Morgannwg University (ABMU) Health Board audiology services between 2016 and 2018. Service access, first hearing aid fitting appointment rates and hearing loss at time of first hearing aid provision were used to index population hearing loss versus area-level indices of deprivation based on patient postcode.SettingPrimary and secondary care.Participants59 493 patient entries met the inclusion criteria. Patient entries were grouped by age (18–30, 31–40, 41–50, 51–60, 61–70, 71–80, >80 years) and deprivation decile.ResultsThe interaction between age group and deprivation decile predicted access rate to ABMU audiology services (b=−0.24, t(6858) = −2.86, p80 years. First hearing aid fitting rates were highest among the most deprived in the four youngest age groups (pConclusionsHearing health inequalities are prevalent among adults accessing ABMU audiology services. Our findings suggest that deprivation increases the likelihood of developing hearing loss, brings earlier onset of hearing loss and is linked to delays in getting help for hearing problems. However, it is not possible to know the true scale of these disparities without knowing the hearing health of the Welsh adult population including those who do not seek help for hearing problems.
