Abstract

Patients on maintenance hemodialysis (MHD) experience decreased quality of life (QoL) and significantly higher rates of malnutrition, inflammation, hospitalization and mortality when compared with the normal population. The dietary approach in the different phases of chronic renal failure is one of the most important, and yet controversial, topics in the whole history of nephrology, even when dialysis facilities were not easily available. Although much progress has been made in recent years in recognizing the link between malnutrition, different diseases and increased mortality, no consensus has yet been reached concerning the ideal assessment and management of nutritional status in dialysis patients in Iran. In this study, 70 patients on MHD in the teaching hospitals in Urmia were divided into two groups and were requested to fill in the validated SF-36 QoL questionnaire. One group of 35 patients received dietary counseling while the other did not and acted as controls. The SF-36, a short-form QoL scoring system consists of 36 questions that are compressed into eight multi-item scales covering all aspects of QoL. The two groups studied were similar in age, level of education, gender and duration of dialysis treatment; 46.8% of the patients were female and 52% were male. The total SF-36 score was slightly higher in males compared with females, but this difference was not statistically significant (P = 0.05). The scores were higher in the group counseled about diet. Overall, the difference in physical health, in work activities and QoL as a whole, between the two groups, was statistically significant (t = 2.04, df = 34, P = 0.049; t = 2.04, df = 34, P = 0.049; t = 2.28, df = 1.96, P = 0.043, respectively). The QoL was considerably diminished in HD patients, but less so in the group that was educated about their nutrition. Improvement in QoL is achievable in patients if their discomfort is more effectively treated medically. One of the methods for this is education about their nutritional program, which can be used for other chronic diseases too. More research is needed to assess whether interventions help to improve QoL and lower heath risks among patients on HD.
