Mini Nutritional Assessment (MNA) as a Reliable Tool for Nutritional Assessment of Hemodialysis Patients: A Single-Center Observation.

Objective In this study, we evaluated mini nutritional assessment (MNA) as a tool for the assessment of the nutritional status of end-stage renal disease (ESRD) patients on maintenance hemodialysis (MHD). Methods This prospective cross-sectional study was done from February 2021 till August 2021 on ESRD patients on MHD at our center. Nutritional status was assessed by using MNA score which evaluates four different aspects: anthropometric measures (body mass index [BMI], weight loss, mid-arm and mid-calf circumferences); general assessment (lifestyle, medications, mobility, and signs of depression); short dietary assessment (number of meals, food, and fluid intake) and subjective assessment (self-perception of food and nutrition). Results Out of 195 study subjects, 127 (65.1%) were males and 68 (34.9%) were females. Most women were stay-at-home mothers (57, 29.2% overall and 83.8% among all women), while most men owned their own businesses (44, 22.6% overall). The mean age was 51.2±14 years and the mean duration of hemodialysis was 4.6±4.1 years. Most of our patients belonged to the middle socioeconomic group (110, 56.6%). By using MNA, we found that most are at risk of developing malnutrition (112, 57.4%); however, only 9 (4.6%) patients are malnourished. In our study group, most malnourished patients belonged to the age group of >65 years (5, 56.6%). BMI was found to be significantly associated with MNA (p <0.001). Conclusion MNA is an easy and reliable bedside tool that can be used in ESRD patients on MHD for nutritional assessment. This is helpful in nutritional planning and the prevention of malnutrition.
