The effect of diet training on variations in blood pressure, weight, and some biochemical factors in hemodialysis patients: a clinical trial

Background and aims: Good nutrition in hemodialysis patients is one of the most important factors of increased longevity and decreased hospitalization and it is argued that training is highly effective in this regard. The aim of this study was to determine the effect of diet training on variations in blood pressure, weight, and some factors in the hemodialysis patients referred to hemodialysis ward of Hajar Hospital, Shahrekord. Methods: This clinical-trial study was conducted in 2011 on 100 hemodialysis patients who were recruited based on purposive sampling. Training intervention including face to face training along with offering two training pamphlets was implemented in two sessions within a month for the patients,. Variations in weight, blood pressure, creatinine, and blood urea were measured and recorded by the researcher in initial, after two weeks, and a month after training. The effects of diet training were compared on evaluated factors before and after intervention. Results: In this study, mean age of the studied patients was 56.215.14 ranged 13-80 years old. The weight mean of the patients after one month of training interventions (64.66±14.54) decreased significantly compared to initial stage (66.50±15.10) kg. (P=0.002). Also, the mean systolic and diastolic blood pressure of patients prior to training intervention was 152.44±18.12 mmHg and 88.16±7.64 mmHg, respectively, and one month after training intervention 128.7±13.08 and 79.02±7.5, respectively. This decrease was reported significant (P=0.001). On the variations in creatinine and blood urea of the patients, both decreased throughout the study, but only the decrease in blood urea was reported significant (P=0.001). Conclusion: Since adherence to appropriate diet in this study could cause weight loss, improve blood pressure level, and Moderate blood biochemical factors. Implementation and continuation of training programs in this regard by health caregivers is necessary and important.
