Abstract
Background. Many patients with end-stage renal disease who are undergoing chronic hemodialysis suffer from sleep disturbance. This paper was designed to study the severity and prevalence of sleep disorders and the factors affecting the syndromes in this unique patient group. Methods. We conducted this study by the use of questionnaires. Included in this study were a total of 245 patients at our center who had end-stage renal disease (ESRD) and who received hemodialysis thrice weekly for more than three months. Their demographic data and biochemical and hematologic parameters were analyzed. All patients were asked to complete two questionnaires (in a Chinese version) of the Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory second edition (BDI-II), either by themselves or with assistance from the medical staff. Results. One hundred and sixty-four patients completed both questionnaires with a response rate of 70.4%. Their mean age was 57.9 ± 11.8 (ranging from 23.1 to 83.7) years old. They had been receiving hemodialysis for an average of 49.1 ± 50.9 months before the study. The male to female ratio was 77:87. Seventy six (46.3%) patients had diabetes mellitus. The prevalence of sleep disturbance was 74.4% (122/164), defined as PSQI scores >5. The poor sleepers had higher BDI scores and a higher ratio of females comparing to the good sleepers. By a multivariate analysis, the BDI scores and female sex were the independent predictors of the patients being poor sleepers. In analyzing the poor sleepers, the BDI scores, durations of hemodialysis and hemoglobin levels were the independent factors for predicting the global PSQI scores. Conclusion. The questionnaire showed a high prevalence of insomnia in the dialytic population. The study also attributes a predictive role in sleep quality to gender, depression, dialytic duration, and hemoglobin levels. The data indicate that in the management of insomnia in this patient group, anemia and depression, both of which are potentially correctable, should be assessed.
