Nutritional problems complicate the evolution of geriatric patients and increase their morbidity and mortality. Three main factors modify the nutritional requirements due to age changes: physical activity alterations, weight changes and body composition changes. As early signs of disability in functional performance are considered part of aging, its impact on the nutritional state is ignored. Geriatric population reduces its physical activity and social participation (due to depression, economic hardship and abandonment), and is the most heterogenic because of its great variety of cellular, physiological (hemoglobin levels, thyroid function level, reduced glucose tolerance, etc.) and body composition changes, that linked to other factors (oral cavity and gastrointestinal system changes, and diminished taste and smell senses) contribute to change their nutritional state. Its evaluation is very difficult (significant variation of anthropometric parameters due to aging), but there are tools that have demonstrated a great utility in domiciliary and hospitalized patient assessment, and to establish a prognostic of morbidity and mortality associated to nutritional state, and its timely treatment.1
