Associations between Diet Inflammatory Index Scores and nutritional status in chronic kidney disease patients

Objectives

To examine the relationship between the energy-adjusted dietary inflammatory index (E-DII) and nutritional status, anthropometric measurements, subjective global evaluations (SGA) and biochemical parameters of chronic kidney disease patients.

Methods

Cross-sectional analyses were performed on data collected from individuals.

Participants/setting

Participants included 119 adults aged 19 years and older, who had data from at least three days of valid 24-hour dietary recall data. Main outcome measures nutritional status, anthropometric measurements, SGA and biochemical parameters were collected. Statistical analyses performed Mann–Whitney U test, ANOVA, Kruskal–Wallis and ANCOVA test was used.

Results

It was determined that 79.8% of the patients were well-nourished, 19.3% had moderate malnutrition, and 0.9% had severe malnutrition. The patients with severe malnutrition was in the last quartile. It was determined that macronutrients and all vitamin and mineral intakes decreased in the last quartile values compared to the first quartile values (P < 0.05). After adjustment for age, sex, energy intake and glomerular filtration rat, there was a significant differences in triceps skinfold thickness and body fat percentage among the four quartiles. There was an increase in the C reactive protein levels from the first quartile to the third quartile (P < 0.05).

Conclusions

This study shows that E-DII is a good tool for assessing the overall inflammatory potential of diet in chronic kidney disease patients.
