Résumé

De par ses conséquences et sa prévalence élevée, la fragilité peut être considérée comme un problème majeur chez le sujet âgé. Son origine est multifactorielle, compte tenu de la fréquence des déficits nutritionnels, leurs rôles quant à la survenue de la fragilité doivent être connus. Il est désormais bien établi que des apports protéiques et énergétiques insuffisants sont directement reliés à la fragilité par l’intermédiaire de plusieurs de ses composantes. Les données récentes soulignent aussi toute l’importance des micronutriments dont le déficit conduit à une fragilité indépendamment du rôle des macronutriments. Les données disponibles indiquent que les aspects qualitatifs doivent aussi être pris en compte dans l’alimentation des personnes âgées. Un suivi tenant compte de ces différents aspects apparaît un élément majeur dans la stratégie de prévention et de prise en charge de la fragilité.

Abstract

Due to the consequences and its increased prevalence, frailty can be considered as a common problem for the elderly patient, with its origins linked to a number of factors; the frequency of poor nutrition and its role in causing frailty needs to be understood. It is, however, well established that insufficient protein intake and a lack of exercise are directly related to frailty, due to a combination of many components. Recent data also highlights the importance of micronutrients, a lack of which can lead to frailty, independent of the role of macronutrients. This data indicates that qualitative aspects must also be taken into consideration when it comes to providing food for the elderly. Careful monitoring of these different aspects would appear to be a key factor in prevention strategies and the management of frailty.
