ABSTRACT
Objectives
To investigate the association between diabetes mellitus (DM) and the prevalence and severity of hearing loss, in a population of community-dwelling older adults in Singapore.
Materials and Methods
This is a retrospective, cross-sectional study of 1787 adults aged 60-100 who had undergone a comprehensive audiological assessment in a community-based audiology clinic. Data extracted included their age, hearing profile, medical history and comorbidities collected through verbal interview at the point of audiologic assessment. Multivariate linear regression and multivariate logistic regression were performed to investigate the relationship between DM and hearing loss.
Results
The prevalence of DM in our studied population is 17.9%. After controlling for age, gender, race, hypertension and hyperlipidemia status, DM was found to be independently associated with at least moderate hearing loss (Adjusted OR 1.3 [95% CI 1.06-1.59], p=0.012). This was especially so in the younger (<70) age group (Adjusted OR 1.7 [95% CI 1.18-2.44], p=0.004).
Conclusion
DM is an independent risk factor for the presence of at least moderate hearing in community-dwelling seniors. Individuals aged <70 with DM should be screened for hearing loss to enable early intervention.
