Background: Amongst chronic diseases, end-stage renal disease (ESRD) deserves special attention in the context of health-related quality oflife (HRQOL). ESRD affects quality of Ufe more intensely than heart failure, diabetes, chronic lung disease, arthritis and cáncer In addition, patients who perceive ¡ow HRQOL withdraw from dialysis treatment more commonly Aim: To identify clinical and laboratory variables associated with health-related quality oflife (HRQOL) in hemodialysis (HD) patients. Patients and methods: We included 174 chronic HD patients from a single unit aged 18 years and older who never received a kidney allograft and survived the first three months of treatment. We used the Khan índex to assess comorbidity and the Medical Outcomes Study 36-Item Short Form Health Survey Questionnaire (SF-36) to measure HRQOL. Resulte: Amongst the eight domains of HRQOL, physical role had the lowest score (35.0±43.0) and social function the highest (64.3±27.7). In the multivariate analysis, age was associated with seven of eight domains, excepting bodily pain. Albumin was associated with five of eight domains. Time on dialysis, hemoglobin and calcium-phosphorus product were associated with physical function, bodily pain and vitality, respectively. Conclusions: Age and albumin were the main variables associated with quality life, and the calcium-phosphorus product was associated with a strategic domain: vitality. Attention to albumin and ageing effects, control ofthe calcium-phosphorus product and improvement of physical conditioning are necessary to achieve better HRQOL.
