Introduction: Sleep disorders increase with aging. Comorbidities cause a further increase in sleep disturbance. The aim of the study was to evaluate the relationship between subjective sleep quality and depression in subjects aged older than 65 years and undergoing hemodialysis.

Materials and Method: Socio-demographic data of participants were recorded in this crosssectional study. The Pittsburg Sleep Quality Index and the Beck Depression Inventory were administered face to face. Vital measures and Body Mass Index calculations were completed. Blood samples were taken for hemogram, biochemical parameters.

Results: Fifty two female and 47 male patients were included in the study. Their mean age was 72.11±5.79 years. The mean Beck Depression Inventory score was 11.95 ± 6.80. Mild, moderate and severe depression, as measured by the Beck Depression Inventory, were 77.8%, 20.2% and 2% of patients, respectively. The mean Pittsburg Sleep Quality Index was 7 (3-12). Those with good and poor sleep quality were 40.4% and 59.6%, respectively. Statistically significant differences were not found between age, duration of dialysis, body mass index, and systolic and diastolic arterial blood pressures, and sleep quality. There was a statistically significant difference between sleep quality and Beck Depression Inventory (p=0.000). Moderate to severe depression was detected in 32.2% of poor sleepers and only 7.5% of good sleepers.

Conclusion: The quality of sleep is significantly impaired in elderly patients undergoing hemodialysis. Advanced age, with co-morbid diseases, adversely affects the quality of sleep. Poor sleep quality and depression trigger each other. The quality of life in elderly end stage renal failure patients can be improved and possible morbidity can be prevented by investigating patients' quality of sleep to diagnose a possible depression.
