Malnutrition among Egyptian hemodialysis patients: prevalence and risk factors

Abstract

Background Malnutrition commonly affects hemodialysis (HD) patients. Malnourished HD patients have increased morbidity and mortality. We aimed to assess the prevalence and risk factors of malnutrition among Egyptian hemodialysis patients. Material and methods This is a cross-sectional study carried out on ESRD patients with regular HD. All participants were subjected to detailed history taking and complete physical examination. Assessment of nutritional status was done using subjective global assessment (SGA). Anthropometric measures included mid-arm circumference (MAC), triceps skin fold (TSF), and body mass index (BMI) assessment. Results One hundred thirty patients with a mean age of 55.2 ± 12.6 years, completed the study. The mean duration of HD was 4.51 ± 3.68 years. The mean SGA was 12.1 ± 3.9. Malnutrition was present in 34 (26.2%) patients [mild to moderate (23.8%), severe (2.4%)]. Patients had a mean BMI of 25.69 ± 4.5 kg/m2, a mean MAC of 25.9 ± 4.9 cm, and a mean TSF of 18.1 ± 8.9 mm. There was a significant negative correlation between malnutrition and mid arm circumference and serum Na with P value of 0.003 and 0.012, respectively. Patients with malnutrition had a significantly longer duration on HD (P=0.004), lower Kt/V (P=0.040), lower serum albumin (P=0.007), lower BMI (P=0.002), less MAC (P=0.002), less TSF (P=0.002). Conclusions Malnutrition is common in HD patients with a significant inverse correlation with mid arm circumference and serum Na. Malnourished patients had a longer duration on HD, lowered serum albumin, BMI, dialysis adequacy and anthropometric measures.
