The Geriatric Nutritional Risk Index (GNRI) is a nutrition-risk metric used in older populations to estimate morbidity and mortality risk associated with undernutrition. Lower scores indicate higher nutritional risk and may guide intervention intensity.
Formula: GNRI is a composite nutrition-risk index; lower totals indicate higher risk.
GNRI has broad validation in geriatric and chronic disease cohorts as a prognostic nutrition-risk indicator.
Lower GNRI scores indicate higher nutrition-related risk and support proactive intervention.
Use for nutrition-risk stratification in older adults, especially in medically complex populations.
Cutoff performance varies by population and disease context; integrate with full clinical nutrition assessment.
