Predictors of Poor Sleep Quality in Elderly Individuals in Western Iran: A Population-Based Cross-Sectional Study.

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, individuals in household management roles faced a dramatically increased risk of poor sleep quality. These findings offer preliminary evidence for the potential effectiveness of early interventions and prevention strategies designed to improve sleep quality and reduce social frailty in the elderly.
