ABSTRACT

With the increase in life expectancy, the aging of the population increases, implying an increasing number of very old people with dietary difficulties. A significant part of age-related organic changes has to do with one's lifestyles. Eating habits or nutritional status have a major impact on good or bad aging, as well as influencing the onset and aggravation of certain chronic diseases. On the other hand, the existence of chronic diseases in the older adult can also negatively influence the state of nutrition, by decreasing appetite and reducing the intake of indispensable nutrients.

The incidence of malnutrition is high in institutionalized older adult, therefore, its early, accurate and rapid diagnosis is essential to allow an adequate nutritional intervention to reverse all complications. On the other hand, the intervention should be personalized, and as such, adjusted to the needs of each individual. The AGA@4life intervention model embodies this vision of multidisciplinary and personalized intervention, based on a tailor-made nutritional intervention, involving the following steps: Identification of nutritional risk; nutritional assessment (anthropometric assessment: weight, height, perimeter, bioimpedance); Assessment of food intake through 24 h food frequency and daily food questionnaires; Biochemical Assessment; nutritional intervention with individual and personalized adjustment of the food plan and reformulation of menus and capitations.
