Background:Sleep disorders are prevalent but underrecognized in patients with chronic kidney disease (CKD) inparticular those with end stage renal disease (ESRD) undergoing dialysis therapy.9 Although variable,their prevalence has been reported to be much higher than in the general population Aim: To study the pattern of sleep disorder in patients with end stage renal disease onhaemodialysisandtheirassociationwithcomorbidities. Material and Methods:Thiswasacrosssectionalstudyon100patientsattendingthedialysiscentreofChalmedaAnand Rao InstituteofMedicalSciences.Patient datawascollectedusingaself-administeredquestionnaire. Results:Ofthe100patientsofendstagerenaldisease(ESRD)onhaemodialysis,76(76%)hadsomeformofsleepdisorder.Thepatternofsleepdisorderswas:64(84.21%)hadinsomnia,25(32.89%)hadexcessive daytime sleepiness (EDS), 20 (26.32%) had obstructive sleep apnoea (OSA), 7 (9.21%) hadrestlesslegsyndrome(RLS),2(2.63%)hadnightmaresand2(2.63%)hadsleep-walking.Patientswithhistoryofsmoking(p=0.034)andhistoryofalcoholconsumption(p=0.010)ortreatmentwithbenzodiazepines (p=.002) were more prone to sleep disorders. Patients with sleep disorders werefound to have lower hemoglobin and iron stores. An association was specially noticed between RLSandlowironstatus. Conclusion:Threeoutof fourof patients withESRD onhemodialysis havesleep disorders.InsomniawasnotedtobethecommonestsleepdisorderfollowedbyEDS.
