Comparison of sleep quality and quality of life indexes with sociodemographic characteristics in patients with chronic kidney disease.

Aims: Chronic kidney disease (CKD) is a serious health problem due to high mortality and morbidity, negative impact on the patients' quality of life (QOL), high diagnostic and therapeutic cost, and the burden on society. Sleep, which is one of the main needs of the human body, is important regarding the health and QOL in all ages. The objective of our study was to plan the quality of sleep and life quality in adults with CKD.

Materials and Methods: Total 240 cases (91 healthy volunteers, 75 predialysis patients, and 74 hemodialysis (HD) patients) were included in our study. Our study was designed as a prospective survey with a face-to-face interview method. The sleep quality was evaluated with Pittsburgh Sleep Quality Index (PSQI). The WHO Quality of Life-short version (BREF) survey questions were used for QOL, and scoring was performed.

Results: The analysis showed that the results of PSQI scores, QOL scores, and evaluation of the age variable were statistically significant (P = 0.001, P < 0.001, P < 0.001, respectively). Likewise, the PSQI scores were low in healthy volunteers but were the highest in predialysis patients. The scores of the HD patients were between the scores of predialysis and healthy volunteers. The score of the QOL increased with educational level. There was a positive correlation between Modification of Diet in Renal Disease (MDRD) level and QOL (P < 0.001; r = 0.260) and a negative correlation between MDRD level and PSQI score (P < 0.001, r = -0.202).

Conclusion: Like in HD patients, close follow-up of predialysis patients with CKD is critical considering the resolution of the encountered problems. We believe that the increase in QOL and sleep in patients with CKD may decrease the morbidity.
