Sleep disorders and their etiology in dialysis population have received increasing attention over the last decade. However there occurrence in predialysis patients which bears highest burden of Chronic kidney disease (CKD) population, is still a neglected area. This study aimed to measure the prevalence of ‘poor sleep’ in early CKD patients (stage 2-4) and to examine the association between quality of sleep and various demographic and biochemical parameters. Quality of sleep was measured using the Pittsburgh Sleep Quality Index (PSQI) in 100 prevalent CKD Stage 2-4 patients and daytime sleepiness, using Epworth Sleepiness Score (ESS). Other biochemical parameters were reviewed from case-records of patients. Sixty-two subjects were ‘poor sleepers’ defined as a global PSQI score of >5.There was no statistically significant correlation between quality of sleep and blood urea and serum creatinine however ’Poor sleep’ correlated significantly with age (p= 0.014), BMI (p= 0.020), anemia (p=0.013) and ESS score (p<0.001). ‘Poor sleep’ is common in predialysis population. Quality of sleep decreases in the early stages of CKD and does not appear to be associated with the subsequent degree of renal failure. Large prospective longitudinal studies of quality of sleep in CKD patients are needed to examine the association between deterioration of renal function and quality of sleep while controlling for potential confounding variables.
