Nutritional status of home hemodialysis patients.

We studied the nutritional status of 32 patients (23 men), aged 50 (SD14) yr, on home hemodialysis (HHD) for one-138 months. No formal dietary restrictions were imposed. Anthropometric measurements were made using standard techniques, diet assessed by three-day dietetic diary and interview and plasma concentrations of nutrients were measured. Mean caloric intake was 29.4 (SD 10.7) kcal/kg; 24 (75%) patients had lower energy intakes than recommended for normals. Protein, vitamin C and folate intakes were above recommended minimum safe intakes. Intakes were less than recommended for calcium in four (13%) patients, iron in one (3%) and vitamin B12 in two (6%). One-third of both sexes had body mass indices (kg/m2) less than 25th percentile for normals, but none was less than 80% of ideal bodyweight. Arm muscle circumference was less than 10th percentile for normals in six men and three women. Triceps skin fold thickness was less than 10th percentile in four men (17%) and five women (55%). No anthropometric measurements were correlated with energy, protein or fat intake. Biochemical measurements were not useful in predicting protein intake. Neither nutritional intake nor anthropometric measurements were correlated with the duration of HHD. There was little evidence of malnutrition and wasting in this group of well rehabilitated HHD patients.
