OBJECTIVE: This study investigated the prevalence of insomnia and its associated factors among community-dwelling Korean elderly. METHODS: A cross-sectional survey examining a person's physical and psychological health status, including sleep, was administered among 1,500 individuals aged 65 and older. All participants were community-dwelling Korean elderly. RESULTS: We found that the overall prevalence of insomnia during the preceding month was 43.1%, including difficulty initiating sleep (27%) and difficulty maintaining sleep or early morning awakening (37.9%). Multiple logistic regression analysis showed that chronic diseases [odds ratio (OR) 2.42, 95% confidence interval (CI) 1.59-3.71], depression (OR 1.86, 95% CI 1.31-2.63), female (OR 1.63, 95% CI 1.27-2.10), suicidal ideation (OR 1.60, 95% CI 1.05-2.45), poor perceived health (OR 1.57, 95% CI 1.14-2.17), unemployment (1.51, 95% CI 1.13-2.03) were associated with an increased prevalence of insomnia. CONCLUSION: Insomnia is prevalent among community-dwelling Korean elderly, and multiple psychosocial factors are associated with insomnia.
