 sleep is an effective factor in the process recovery from diseases. Many variables affect the ‎sleep quality of hospitalized older patients. Aim: this study was conducted to evaluate the quality of ‎sleep and its related risk factors in hospitalized older patients in Kashan’s hospitals, Iran 2009. ‎Settings and design: a cross-sectional study was carried out on a sample of 400 hospitalized older ‎adults in the hospital of Kashan, Iran.

 Materials and methods:

the Farsi Pittsburgh Sleep Quality ‎Index (FPSQI) was used for gathering data. A global sum of 6 or greater indicates a poor quality of ‎sleep. Statistical analysis used: data were analyzed using the Chi-square test, t-test, ANOVA, and ‎binary logistic regression at the multivariate model.


the overall quality of sleep of the ‎patients in this study was poor. In the final regression model, sex (OR = 0.342), level of education ‎‎(OR = 0.470), type of ward (OR = 0.592), previous hospitalization experience (OR = 2.336), and use ‎of hypnotics in hospital (OR = 3.633) were the most important predictors of sleep quality. The most ‎prevalent sleep disturbing factors were worries and anxiety, environmental noises and pain. ‎However, the most negative effects on the PSQI mean score were reported to be from dyspnea, ‎environmental lights, and changes in the sleep habits. Quality of sleep also had significant ‎relationship with sleep latency (P = 0.001) and having a respiratory disorder.


the ‎knowledge of sleep disturbing factors in hospitalized older adults might help in planning preventive ‎strategies to improve quality of sleep.‎
