[Nutritional assessment in primary practice in elderly patients]

Undernutrition is frequent and often underdiagnosed among older adults in every setting (home, nursing home, hospital), and is associated with increased morbidity and mortality. In this context, a systematic periodical nutritional assessment is proposed in patients aged 75 years and over. Without a consensus, the most widely used diagnostic criteria is an unintentional weight loss of 5% over a month or 10% over 6 months. When undernutrition is present, multimodal interventions are provided to address each potentially contributing comorbid condition and to promote increased caloric intake. Follow-up and adaptation of interventions after 3 months are required.
