The Prevalence and Predictors of Sleep Disturbance in the Elderly: A Population-Based Study in Shiraz, Iran

Sleep disturbance is one of the main complaints of the elderly. In this study, we aimed to determine the correlates of sleep disturbance in the elderly population.

In this population-based study, sleep disturbance was assessed by completing the Pittsburgh Sleep Quality Index. The collected data were analyzed in SPSS.

A total of 386 elderly individuals participated in this study. Overall, 213 (55.2%) participants reported sleep disturbances. The elderly with heart disease, low quality of life (QOL), chronic pain, single marital status, and osteoporosis had the lowest quality of sleep (QOS), followed by non-providers of family’s costs. The elderly with chronic pain and lower QOL suffered from daytime dysfunction more than those with osteoporosis, who mostly suffered from sleep latency.

One out of two elderly people had low QOS. Heart disease, low QOL, chronic pain, and osteoporosis should be considered in the elderly QOS improvement.
