Predictors of Poor Sleep Quality in Elderly Individuals in Western Iran: A Population-Based Cross-Sectional Study
Abstract
Background: Poor sleep quality in the elderly is a prevalent issue that can significantly impact overall health and quality of life. This study aimed to assess the prevalence of sleep disorders and the factors contributing to poor sleep quality among older adults in Western Iran. Study Design: This is a cross-sectional study. Methods: This study involved 403 elderly people. The following tools were employed to collect data: the Pittsburgh Sleep Quality Index (PSQI), the Leisure and Pleasure Activities Database (a quality-of-life tool), the standardized Depression, Anxiety and Stress Scale (DASS-21), and the Abbreviated Mental Test (AMT)for cognitive assessment. A backward stepwise selection method was employed to finalize the variables for multiple logistic regression analysis. Results: The overall prevalence of poor sleep quality was 44.7%. With each one-point increase in stress, the likelihood of experiencing poor sleep quality increases significantly (adjusted OR: 1.09, P<0.001). The number of children in the household was found to have a protective effect against poor sleep quality (adjusted OR=0.63, P=0.008). Furthermore, elderly individuals working as housekeepers had higher odds of poor sleep quality than those employed elsewhere (adjusted OR=7.45, P=0.005). Conclusion: A significant association was observed between elevated stress levels and poor sleep quality. Interestingly, the presence of children in the household appeared to offer a protective effect. Conversely,…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 403 participants or records.
