Abstract

With increasing age alterations of metabolism, appetite regulation, and body composition have been observed. As a consequence the risk of malnutrition is much higher in older than in younger persons. Though the highest prevalence rates have been described for the hospital and rehabilitation setting, most older persons with overt malnutrition are found in the community. Here persons with chronic comorbidity and low functionality show the highest risk. Routine screening for malnutrition is therefore indicated in older persons. For the successful treatment of malnutrition it is important to consider also medical and social etiologic factors before starting nutritional therapy. With regard to the preservation of muscle mass and muscle strength, adequate protein intake deserves careful consideration. Besides the implementation of regular snacks between meals, temporary application of oral supplements which are high in energy and protein is indicated. Especially during and after hospital stays, the beneficial interaction between nutrition and exercise has to be considered with regard to functionality and quality of life in older persons.
