Objective: To establish whether ethnic inequalities exist in levels of self-reported hearing difficulty and hearing aid use among middle-aged adults.Design: Cross-sectional data from the UK Biobank resource.Study sample: 164,786 participants aged 40-69 who answered hearing questions.Results: After taking into account objectively assessed hearing performance and a corresponding correction for bias in non-native English speakers, as well as a range of correlates including demographic, socioeconomic, and health factors, ethnic inequalities were observed in both hearing aid use and self-reported hearing difficulty. There were lower levels of hearing aid use for people from Black African (OR 0.36, 95% CI 0.17-0.76), Black Caribbean (OR 0.37, 95% CI 0.22-0.64) and Indian (OR 0.59, 95% CI 0.41-0.85) ethnic groups, compared to the White British or Irish group. For equivalent levels of objectively assessed hearing, men from most ethnic minority groups, and women from Black African, Black Caribbean and Indian groups were less likely to report hearing difficulty than their White British or Irish counterparts.Conclusions: For equivalent levels of hearing loss, use of hearing aids is lower among ethnic minority groups.Inequalities are partly due to lower levels of self reported hearing difficulty among minority groups. However, even when self reported hearing difficulty considered, hearing aid use remains lower among many ethnic minority groups. As reasons for low hearing aid use in ethnic minorities may differ between groups, potential reasons for low use including barriers to services, the effect of discrimination, and attitudes to hearing loss and hearing aid use, should be explored using culturally safe methodology with each major UK ethnic group.
