Inflammation is associated with a worsening of presbycusis: evidence from the MRC national study of hearing
Objective: Inflammaging, a state of chronic inflammation in the elderly, is now thought to be a key element of the ageing process and contributor to age-related disease. In a previously published study, we identified a significant association between inflammation levels and severity of presbycusis among individuals aged 63 to 73 ('younger old") within an available audiometric range 0.5 to 4 kHz. Our aim was to see if this association would be identified among participants in the MRC national study of hearing, and whether the strength of the association would increase with greater age, or for very low or very high audiometric frequencies. Design: Cross-sectional analysis of cohort data. Study sample: Three hundred and sixty community-dwelling adults age 60 years and over, representing all those with white blood cell count and audiometric data available. Results: A significant independent association between (higher) WBC and (worse) hearing level was identified. This effect increased with age. The strongest association was among those over 75, for whom average hearing threshold levels among those with lower WBC was 17 dB better than those with higher WBC. Conclusions: The current findings support an association between inflammaging (a condition potentially amenable to pharmacological treatment or lifestyle management) and presbycusis

Abstract
Objective: Inflammaging, a state of chronic inflammation in the elderly, is now thought to be a key element of the ageing process and contributor to age-related disease. In a previously published study, we identified a significant association between inflammation levels and severity of presbycusis among individuals aged 63 to 73 ('younger old") within an available audiometric range 0.5 to 4 kHz. Our aim was to see if this association would be identified among participants in the MRC national study of hearing, and whether the strength of the association would increase with greater age, or for very low or very high audiometric frequencies. Design: Cross-sectional analysis of cohort data. Study sample: Three hundred and sixty community-dwelling adults age 60 years and over, representing all those with white blood cell count and audiometric data available. Results: A significant independent association between (higher) WBC and (worse) hearing level was identified. This effect increased with age. The strongest association was among those over 75, for whom average hearing threshold levels among those with lower WBC was 17 dB better than those with higher WBC.

Additional Information:
It is estimated that nearly 2 billion people world-wide will develop age-related hearing loss, with impacts on social and cognitive functioning and associated increased risks of co-morbidity including dementia. Our study identified a clear link between chronic age-related systemic inflammation and the progression of hearing loss. A particular novel finding was that this relationship increases with age. This finding indicates that lifestyle or medical interventions to manage chronic inflammation can reduce the progression of hearing loss in the elderly. This opens up new avenues in slowing down or preventing the development of hearing loss.
