Prevalence and factors associated with malnutrition among hemodialysis patients in a single hemodialysis center in Vietnam: A cross-sectional study

Malnutrition is a common problem among hemodialysis patients that increases morbidity and mortality and decreases the quality of life. This study aimed to assess the prevalence of malnutrition and associated factors and survey the consumption of energy and several nutrients among hemodialysis patients. A prospective observational study with a cross-sectional design was conducted on 76 patients on hemodialysis therapy at Nguyen Tri Phuong Hospital, Ho Chi Minh City, Vietnam, for 2 months (from May to July 2022). Dialysis malnutrition score was used to determine patients’ nutritional status. Data about their biochemical parameters were retrieved from records with the newest results. Among the 76 patients, 38 (50.0%) were female. The mean age of the patients was 55.0 ± 13.5 years. Based on the dialysis malnutrition score, 56 (73.7%) patients had mild to moderate malnutrition, while 2 (2.6%) had severe malnutrition. The average energy intake was 21.5 kcal/kg/day, with only 3.9% meeting the recommended intake. The average protein intake was 1.0 g/kg/day, and about 10.5% of participants complied with the recommended protein level. In addition, the majority of patients did not reach the recommendations for sodium (56.6%), potassium (88.2%), phosphate (75.0%), and calcium (82.9%). We found a significant association between patients’ occupation (P < .05), dialysis vintage (P < .001), and malnutrition status. Malnutrition is widespread among Vietnamese hemodialysis patients, which necessitates regular assessment and monitoring. We recommend paying more attention to the nutritional status of patients who are unemployed, retired, or stopped working and those with ≥ 5 years of hemodialysis.
