The effect of dietary regimen education on the laboratory variables in hemodialysis patients

Nutrition is an important factor in the treatment of patients with chronic renal disease and inappropriate dietary regimen can decrease quality of life and increase morbidity and mortality in these patients. This study was aimed to investigate the effect of diet education on the laboratory parameters in patients undergoing hemodialysis. In this quasi experimental study، 99 patients undergoing hemodialysis were randomly assigned into experimental and control groups. Demographic form and testing checklist was used for data gathering. Dietary face to face education was conducted for experimental group but the control group received routine education. After three months، laboratory variables in patients were evaluated and recorded. Data were analyzed using Chi-squared test، independent T-test and Paired T-test. Demographic variables of the two groups were not significantly different (P>0. 05). There was no significant difference between the values of Hb، FBS، Cr، Na، K، Ca، Phosphor and albumin between two groups before intervention (P>0. 05)، but after the intervention، there was a significant difference in these laboratory parameters (P<0. 05). Study results indicate positive effects of dietary education on the laboratory indicators in the intervention group compared to the control group. Considering this، dietary education to nurses and other relevant personnel is needed to improve conditions for patients undergoing hemodialysis.
