Introduction: The nutritional status of old hemodialysis patients determines their prognosis. The aim of this study was to evaluate the spontaneous dietary intake of hemodialysis of elderly patients.
Methods: This cross-sectional descriptive study included 40 elderly hemodialysis patients recruited at the M8 nephrology department of Charles Nicolle hospital in Tunis. All patients went through a clinical examination to specify anthropometric measurements and a dietary survey based on food registration for 3 consecutive days to obtain a nutritional assessment.
Results: The evaluation of patients' energy intake showed an average daily intake of 25.3±12.3kcal/kg of ideal weight/day. The average total energy intake of patients on dialysis and non-dialysis days was 29.7±17.7kcal/kg and 20.9±6.9kcal/kg, respectively, with a statistically significant difference (P=0.001). The average daily protein intake was 0.99±0.57g/kg on the day of no dialysis. It decreased statistically significantly (P=0.005) on the day of no dialysis at 0.73±0.28g/kg. Phosphorus consumption was excessive on dialysis and non-dialysis days respectively in 20% and 3% of cases. Deficiency of calcium intake affected the entire population studied on the day of non-dialysis. Only 6% of patients had a calcium intake satisfactory on the day of dialysis.
Conclusion: A lot of dietary errors were noticed in our study. The assessment of nutritional intake in elderly people with hemodialysis should be part of their management systematically.
