A dietary survey in Indian hemodialysis patients.

Malnutrition is a common problem in maintenance hemodialysis (MHD) patients, and compromised intake is an important cause. There is no information available about the nutrient intakes of MHD patients in India. The nutrient intakes of 106 MHD patients were studied cross-sectionally and on follow-up. A 24-hour recall was used on 4 consecutive days. After 2 months on dialysis, the mean energy intake was 29 +/- 6.6 kcal/kg ideal body weight (IBW) and the mean protein intake was.93 +/-.39 g/kg IBW (high biological value [HBV] protein 49% +/- 8.5%). Dietary deficiency of both protein and calories was present in 64.9%. Intake was better on nondialysis days compared with dialysis days, and in women and older patients. On follow-up there was no significant increase in food intake up to 6 months. After that, the total calorie intake increased significantly with a disproportionate drop in high biological value protein consumed and appeared to be derived predominantly from carbohydrate food (mean kcal/kg, 37 +/- 6.9; mean protein g/kg, 0.96 +/- 0.19; ratio of HBV protein to total protein consumed,.42 +/-.09). In summary this study showed suboptimal energy and protein intake in an MHD population. Intakes were further compromised on dialysis days, and with increasing time spent on dialysis, the quality of nutrient intake became poorer.
