The prevalence of malnutrition is high in elderly people in hospital, living in nursing homes, or involved in home care programs. As a consequence of this, the mini nutritional assessment (MNA) has been set up to provide a single, rapid assessment of nutritional status in the elderly. The MNA provides primary care physicians with a tool for rapid screening of patients who may subsequently need a more extensive nutritional assessment. This text focuses on the research and practice of the MNA, and includes topics such as: the MNA and odour perception; the MNA score in people who have aged successfully; the mini nutritional assessment and cancer; and the anorexia of ageing, leptin, and the mini nutritional assessment.
