Prevalence and correlates of insomnia symptoms among older adults in India: Results of a national survey in 2017-2018

Background: This study aimed to estimate the prevalence and correlates of insomnia symptoms among older adults in India. Methods: The study included 72,262 individuals (45 years and older) from the cross-sectional 2017 to 2018 Longitudinal Ageing Study in India Wave 1. Results: The prevalence of insomnia symptoms was 12.7%, 13.2% among women and 11.9% among men. In the adjusted logistic regression analysis, food insecurity (adjusted odds ratio [AOR]: 1.41, 95% confidence interval [CI]: 1.25–1.59), feeling alone (AOR: 1.64, 95% CI: 1.46–1.83), having 3–5 discrimination experiences (AOR: 1.53, 95% CI: 1.32–1.78), having two or more chronic conditions (AOR: 1.65, 95% CI: 1.46–1.86), high functional disability (AOR: 1.80, 95% CI: 1.63–1.99), poor distant vision (AOR: 1.32, 95% CI: 1.17–1.49), poor near vision (AOR: 1.19, 95% CI: 1.07–1.33), edentulism (lost all teeth) (AOR: 1.28, 95% CI: 1.06–1.55), underweight (AOR: 1.11, 95% CI: 1.00–1.23), and pain (AOR: 1.71, 95% CI: 1.54–1.89) were positively associated with insomnia symptoms. High subjective socioeconomic status (AOR: 0.85, 95% CI: 0.76–0.96), urban residence (AOR: 0.90, 95% CI: 0.81–0.99), and medium social network (AOR: 0.87, 95% CI: 0.79–0.96) were negatively associated with insomnia symptoms. Conclusions: More than one in ten older adults in India had insomnia symptoms and several associated factors were identified.
