Diabetic nephropathy : a strong predictor of sleep quality in hemodialysis patients

Abstract EN

Sleep complaints are common in hemodialysis (HD) patients.

Sleep quality (SQ) is a predictor of quality of life and mortality risk in HD.

The aim of this study was to examine factors that may have a role in SQ.

In this cross-sectional analytic study, 138 end-stage renal disease patients receiving maintenance HD for > 3 months were included.

The Pittsburgh Sleep Quality Index (PSQI) was used to measure individual’s SQ.

Patients with a global PSQI score > 5 were assumed as poor sleepers.

Eighty-eight patients (64 %) were classified as poor sleepers.

Poor sleepers were older and more likely had diabetes.

They had significantly higher serum ferritin and calcium levels and lower serum parathyroid hormone level (all P-values < 0.05).

The global PSQI score was positively correlated with age, serum calcium level and presence of diabetes as the underlying cause of renal failure.

In the multi-variable binary regression model, presence of diabetes (Odds Ratio (OR) = 3.67, P = 0.008) and body pain (OR = 1.182, P = 0.014) were the significant independent predictors for poor SQ.

Poor SQ was common among our HD patients, especially among diabetic cases and, therefore, there is a need to pay more attention to the care of this subgroup with regard to the diagnosis and management of sleep complaints.
