Background: The dialysis population is growing and aging worldwide. The aging dialysis population exhibits specific conditions, including sarcopenia, protein-energy wasting, and frailty, that are associated with worse outcomes. Thus, strategies to address these conditions are indispensable to improving prognosis, quality of life, and ability to perform activities of daily living in older patients.
Summary: Several strategies have been employed to manage these conditions. The two major approaches are nutritional therapy and exercise training. These correlate strongly with each other and each is necessary to maintain the health of patients. Ensuring adequate protein and energy intake is the mainstay of nutritional therapy. However, older dialysis patients often have reduced appetite, and appropriate nutritional therapy can enhance appetite. Conversely, nutritional therapy without an appropriate exercise training system will fail to enhance physical function. Thus, the focus of attention has been on exercise training both during dialysis treatment and while at home. The Japanese Society of Renal Rehabilitation has issued a guideline for exercise training in patients with kidney disease. It encourages using the time during dialysis treatment for performing both nutritional intake measures and exercise training. Nutritional care in dialysis patients has previously focused on restriction of dietary intake. However, patients with these malnutrition-wasting conditions should be encouraged to improve their dietary intake and physical activity. Older dialysis patients have heterogenic characteristics in terms of frailty, so their nutritional and exercise plans should be individualized. Key Messages: Individualized management should be used in the heterogeneous older dialysis population, with special considerations for malnutrition-wasting conditions.
