Relationships between Insomnia, Depression, Body Mass Index and Restless Leg Syndrome in End-Stage Renal Disease Patients Receiving Hemodialysis

Abstract

            The cross-sectional study purposed to investigate restless leg syndrome, and to examine the relationships among body mass index, insomnia, depression and restless legs syndrome in patients with end-stage renal disease receiving hemodialysis. One hundred and one end-stage renal disease patients receiving hemodialysis followed up at the nephrology clinics of Phra Nakhon Si Ayutthaya Hospital and Saraburi Hospital were recruited. Research instruments used in this study included a set of structured questionnaires and interviews. Data were analyzed using descriptive statistics, Pearson’s product moment correlation, and Spearman rank correlation coefficient. The results revealed that the mean score of severity of restless leg syndrome of end-stage renal disease patients receiving hemodialysis was 13.91 (at a moderate level). About 43.5% of the patients perceived the severity of restless leg syndrome. Most end-stage renal failure patients receiving hemodialysis had a mean body mass index of 23.72 + 4.36, a mean score on insomnia of 19.62 + 6.05, and a mean score of depression of 12.10 + 8.46. Body mass index, insomnia, and depression were positively, and significantly correlated with restless leg syndrome in end-stage renal disease patients receiving hemodialysis with correlation values of 0.213, 0.521, and 0.416, respectively. In conclusion, body mass index, insomnia, and depression are associated factors of restless legs syndrome in end-stage renal disease patients receiving hemodialysis. So, medical personnel should assess, promote, and provide the patients with information and advice. Finally, a referral system to a health care team to relieve the symptoms ruled out should be considered.
