The prevalence of insomnia and its risk factors among older adults in a city in Turkey's Aegean Region

Aim Experienced by many older adults, insomnia is a significant public health problem that requires the attention of health-care professionals and researchers. This study aimed to identify insomnia and its risk factors among community-dwelling older adults. Methods This cross-sectional study was conducted in Denizli, Turkey. The study sample consisted of 360 elderly individuals aged 60 years and older who were admitted to one of six family health centres for any reason between 29 March 2016 and 17 June 2016. Data were collected by using a descriptive form for the elderly and the Insomnia Severity Index. The chi(2) test was used to compare independent variables and insomnia status. Logistic regression analysis was used for the variables that were found to be significant at the end of the single-variable analysis. Results The mean age of the subjects, all of whom lived at home, was 69.52 +/- 8.36 years. Insomnia was quite common among them (51%), and its severity was low (8.51 +/- 5.56). At the end of logistic regression analysis, a moderate perception of health (OR = 10.859, 95%CI: 3.532-33.385) and the number of medications used (OR = 3.326, 95%CI: 1.014-10.907) were identified as risk factors for insomnia. Conclusion Based on the results of this study, we can state that insomnia is common among older adults. Therefore, older adults who are admitted to health-care institutions should be evaluated for insomnia. Factors identified as affecting insomnia were health perception and the number of medications used. Given that health perception and polypharmacy are associated with chronic disease management, helping the elderly to effectively manage chronic diseases may alleviate insomnia.
