Background: Sleep problems are a critical issue in the aging population, affecting quality of life, cognitive efficiency, and contributing to adverse health outcomes.The coexistence of multiple diseases is common among older adults, particularly women.This study examines the associations between specific chronic diseases, multimorbidity, and insomnia symptoms among older Indian men and women, with a focus on the interaction of sex in these associations.Methods: Data were drawn from 31,464 individuals aged 60 and older in the Longitudinal Ageing Study in India, Wave-1 (2017-18).Insomnia symptoms were assessed using four questions adapted from the Jenkins Sleep Scale (JSS-4), covering difficulty falling asleep, waking up, waking too early, and feeling unrested during the day.Multivariable logistic regression models, stratified by sex, were used to analyze the associations between chronic diseases and insomnia symptoms.Results: Older women had a higher prevalence of insomnia symptoms than men (44.73% vs 37.15%).Hypertension was associated with higher odds of insomnia in both men (AOR: 1.20) and women (AOR: 1.36).Women with diabetes had lower odds of insomnia (AOR: 0.80), while this association was not significant in men.Neurological or psychiatric disorders, stroke, and bone and joint diseases were linked to higher odds of insomnia in both sexes.Chronic lung disease was associated with insomnia in men (AOR: 1.65), but not in women.Additionally, having three or more chronic diseases significantly increased the odds of insomnia in both men (AOR: 2.43) and women (AOR: 2.01).Conclusion: Hypertension, bone and joint diseases, lung diseases, stroke, neurological or psychiatric disorders, and multimorbidity are linked to insomnia symptoms in older Indian adults.Disease-specific management and routine insomnia screening are crucial for promoting healthy aging in this vulnerable population.
