[Practical application of has recommendations (2007 and 2021), concerning the diagnosis of malnutrition in persons aged 70 and over, to patients hospitalized in geriatric follow-up and rehabilitation care].

The 2007 French Haute Autorité de santé recommendation on the diagnosis of malnutrition in the elderly was revised in 2021. The main objective was to compare the prevalence of malnutrition according to the recommendations. The secondary objectives were to compare 3-month mortality and assess the prevalence of sarcopenia and sarcopenic obesity. The 2021 criteria were applied retrospectively to a cohort. Concordance analysis was carried out using Cohen's kappa coefficient and statistical analysis of mortality using Fisher's exact test. There were 135 patients, 60% malnourished with 35% severely malnourished according to HAS 2007, 49% malnourished with 62% severely malnourished according to HAS 2021 with moderate agreement. There were 25 cases of confirmed sarcopenia and one case of sarcopenic obesity. Moderately to severely malnourished people had an increased risk of death at 3 months (HAS 2021).
