PP08 Evaluation Of Nutritional Status In Diabetic And Non-Diabetic Chronic Kidney Disease Patients Using A Web Tool

Abstract

Introduction

Poor nutritional status, a complex consequence of numerous interrelated factors, is poorly characterized in patients with chronic kidney disease (CKD) before they commence dialysis. This study aimed to characterize the risk factors and prevalence of malnutrition among patients with CKD, with or without diabetes mellitus, before they underwent dialysis at a tertiary care public teaching hospital.

Methods

This longitudinal observational study utilized a Pt-Global web tool© to assess the nutritional status of patients based on their Subjective Global Assessment score as follows: a score of two to three indicates that patient and family education is required; scores of four to eight mean that intervention is required as indicated by symptoms; and a score of nine or more indicates a critical need for intervention. Glomerular filtration rate calculated using the Chronic Kidney Disease Epidemiology Collaboration equation was used as the measure of kidney function. Multinomial regression analyses were used to ascertain the predictors of poor nutritional status.

Results

A total of 450 patients (265 men and 185 women) who had CKD, with or without diabetes, and were not on dialysis were recruited during the period of study. The average age of the patients was 53.9 years (standard deviation 14.2). ‘Severe’ malnutrition was present in 152 (33.8%) patients, while 140 (31.1%) were ‘mildly or moderately’ malnourished, and 158 (35.1%) were ‘well-nourished’. Patients with CKD and diabetes were more severely malnourished: 68 were rated as mild or moderate (15.1%) and 91 were rated as severe (20.2%). The prevalence of malnutrition increased with the decline of residual renal function. Fatigue, loss of appetite, pain anywhere in the body, constipation, dry mouth, feeling full quickly, and physical and functional inactivity were the most common risk factors for poor nutritional status.

Conclusions

This study presents real-world evidence of poor nutritional status in patients with CKD and confirms that it is more common in individuals who are diabetic and have poor kidney function and hypoalbuminemia. Emphasis on nutrition in patients with CKD is important for improving their health.
