The National Solidarity Fund for Autonomy (CNSA) has signed an agreement with the Union of Gerontology Centers of France (UGF) to inform frontline workers and policymakers about preventive measures that promote healthy aging. As a result of this collaboration, an initial document on the criteria for the effectiveness of interventions to prevent malnutrition in older adults was published in June 2024. This document makes the knowledge about the essential elements that define the quality of a program accessible to a broader audience, based on a comprehensive analysis of the scientific literature conducted by experts. Deliberately concise, it is organized into eight key points to ensure it is accessible to as many people as possible.
