VISIEDO, Lucía et al. Effect of a personalized nutritional intervention program on nutritional status, quality of life and mortality in hemodialysis patients. []. , 40, 6, pp.1229-1235. 04--2024. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.04756.
Objective:
dietary advice provided through a nutritional intervention program (NIP) is recommended by renal clinic guidelines to prevent or treat malnutrition, that could improve quality of life (QoL) and survival in hemodialysis (HD) patients. This study set out to evaluate the effect of a personalized NIP on the nutritional status and its impact on QoL and mortality in dialyzed patients.
Material and methods:
this was a 12-month intervention study with regular follow-up in which nutritional parameters were measured at baseline and after 6 and 12 months. QoL was assessed by the Kidney Disease Quality of Life version 1.2 (KDQOL-SF) at baseline and at the end of the study. All dialyzed patients received individualized consultations with a trained dietitian. The content of the nutritional education program included a personalized meal plan and educational materials addressing nutrition to manage fluids, electrolytes, and vitamin D.
Results:
a total of 75 patients were included. After the NIP, visceral proteins, phosphorous, potassium and vitamin D levels had improved significantly (p < 0.001). The percentage of well-nourished patients increased by 30 % (p < 0.001). At the end of the study, the well-nourished patients had significantly improved scores on the general summary areas of the KDQOL-SF, reduced worry concerning fluid and dietary restrictions (p < 0.001), and the survival rate was 12 months longer (p < 0.01).
Conclusion:
the results of this study suggest that personalized NIP contributed to improved nutritional status, QoL and survival in HD patients.
