Introduction:

the strict dietary recommendations we impose on patients with advanced chronic kidney disease (ACKD) have negative impact on quality of life.

Objective:

determine whether such restrictions are justified and if an educational program can improve health-related quality of life (HRQL) parameters.

Methods:

we carried out an educational intervention, single center, randomized, controlled clinical trial on ACKD outpatients in Albacete. Seventy-five patients were included, 35 in the control group and 40 in the intervention group. Nutritional assessment was based on the Subjetive Global Assessment (SGA) and body mass index (BMI). We used the SF-36 health questionnaire to measure HRQL. In the intervention group we carried out individual, collective and telephone nutritional interventions, adapting diet advice and restrictions in a personalized way.

Results:

malnutrition measured by Subjective Global Assessment (SGA) in the control group was 20%; meanwhile, in the intervention group it was 29.3% and it improved at the end of the study, but not significantly. BMI showed overweight with a mean of 28.83 kg/m² (DE: 5.4) and 26.96 kg/m² (DE: 4.09), respectively, and did not change throughout the study. The nutritional intervention improved the score in all the subscales except for body pain score. Besides, mental and physical components also improved their scores in the intervention group and worsened them in the control group (p < 0.001).

Conclusions:

quality of life can be improved in ACKD patients applying an educational nutrition program.
