Visual and hearing impairment and their association with depression among middle-aged and older individuals in India: Evidence from a cross-sectional study.

OBJECTIVE

The aim of the study was to determine the prevalence and associated factors of visual and hearing impairment as well as to investigate their association with depression among individuals aged 45 and above in India.

METHODS

The study utilized data from the Longitudinal Ageing Study in India (LASI) Wave 1, (2017-18). The total sample size of this study was 65,562 individuals aged 45 and above. Descriptive statistics along with bivariate and multivariable analyses were performed to fulfill the objectives.

RESULTS

The prevalence of visual impairment in the study population was 32.1 percent, whereas the prevalence of self-reported hearing impairment was 6.9 percent. In the logistic regression models, both visual impairment [Adjusted odds ratio (AOR)-1.06; 95% Confidence interval (CI):0.99-1.14] as well as hearing impairment [AOR-1.25; 95% CI:1.11-1.41] were found to be significantly associated with depression. Moreover, individuals with a single impairment were 8 percent [AOR-1.08; 95% CI: 1.01-1.16] and individuals with dual impairment were 36 percent [AOR-1.36; 95% CI:1.13-1.65] significantly more likely to have depression.

CONCLUSION

Individuals with sensory impairment were more likely to suffer from depression and the risk was significantly higher among individuals with dual impairment. Therefore, clinicians dealing with individuals with sensory impairments must be aware of the likelihood of comorbid depression in order to provide timely screening and treatment.
