Background:Sleep disorders and depression, accompanied by reduced quality of life and increased mortality are the most common psychological problems in dialysis patients. This study was conducted with the aim to investigate depression and sleep quality and their association with some demographic and clinical factors in hemodialysis patients.Method:This descriptive-correlative study was conducted on 310 patients undergoing hemodialysis in 8 centers in educational hospitals in Mazandaran University of Medical Sciences. Data collection tools included a demographic questionnaire, Beck Depression Inventory, and Pittsburg Sleep Quality Index (PSQI). Statistical analysis was conducted using Chi-Square test and regression model.Results:Results obtained showed 44.8% depression in patients. Significant relationships were found between depression and increased blood phosphorus (P=0.002) and urea (P=0.001). Poor sleep quality was observed in 73.5% of hemodialysis patients, which was found significantly related to aging (P=0.048), female (P=0.04), and reduced frequency of weekly hemodialysis (P=0.035).Conclusion:Depression and poor sleep quality are two common factors in hemodialysis patients, but patients do not overtly show symptoms of these disorders.

This descriptive correlational study was aimed at determining the relationship of hemodialysis shift with sleep quality and depression in 310 hemodialysis patients. Demographic and Clinical Questionnaires, the Pittsburgh sleep quality index, and Beck's Depression Inventory were used to ascertain the aforementioned relationship. Among the patients, 59.6% reported poor sleep quality and 44.8% reported experiencing depression. Results show that these conditions were significantly related to many factors. Although dialysis shift was not significantly related to sleep quality and depression, sleep quality was found significantly associated with age, female gender, illiteracy, unemployment, residence in rural areas, diabetes, addiction to sedatives, and phosphorus levels. A significant relationship was also found between depression and phosphorus levels. Logistic regression predicted age, gender, illiteracy, unemployment, residence in rural areas, and addiction to sedatives as factors for poor sleep quality. A body mass index (BMI) above 30, decreased urea, and increased phosphorus were predicted as factors for increased depression.

Background and Purpose: Sleep disorders are a common problem in patients undergoing hemodialysis. Poor sleep quality is considered as a potential predictor for mortality and reduced quality of life in these patients. This study aimed to evaluate subjective sleep quality in hemodialysis patients and its association with hemodialysis timing.Methods: This descriptive-correlational study was conducted on 125 patients undergoing hemodialysis in eight teaching hospitals affiliated to Mazandaran University of Medical Sciences, Iran in 2015. Dialysis patients were selected from all the timings. Subjective sleep quality was measured using Pittsburgh Sleep Quality Index (PSQI). In addition, participants completed Beck Depression Inventory (BDI). Data analysis was performed by using Chi-square test, ANOVA and logistic regression model. Results:In total, 210 patients were enrolled in this study, and 79 patients (63.2%) had poor sleep quality. Moreover, no significant association was found between subjective Conclusion:According to the results of this study, poor sleep quality had no significant correlation with hemodialysis timing. Since subjective sleep quality is a common problem in hemodialysis patients, nursing care plans should be implemented to improve this parameter and quality of life in these patients.
