Background The Nutri-Score front-of-package labelling classifies food products according to their nutritional quality, so healthier food choices are easier when shopping. This study prospectively assesses the association of a diet rated according to the Nutri-Score system and incident frailty in community-dwelling older adults. Methods Cohort study with 1,875 individuals aged ≥60 recruited during 2008–2010 in Spain. At baseline, food consumption was assessed using a validated dietary history. Food was categorised into five Nutri-Score labels (A/green—best quality; B, C, D, E/red—worst quality) utilising an algorithm established in 2017 and currently in use. For each participant, a Five-Color Nutri-Score Dietary Index (5-CNS DI) in grams per day per kilogram was calculated. The 5-CNS DI sums up the grams per day of food consumed times their corresponding nutritional quality value (from A rated as 1 to E rated as 5) and divided by weight in kilograms. From baseline to December 2012, incident frailty was ascertained based on Fried's criteria. Statistical analyses were performed with logistic regression adjusted for main confounders. Results After a mean follow-up of 3.5 years, 136 cases of frailty were identified. The multivariable-adjusted odds ratios (95% confidence interval) of incident frailty across increasing quartiles of the 5-CNS DI were 1, 1.51 (0.86–2.68), 1.56 (0.82–2.98) and 2.32 (1.12–4.79); P -trend = 0.033. The risk of frailty increased by 28% (3–58%) with a 10-unit increment in this dietary index. Similar results were found with the Nutri-Score algorithm modified in 2022. Conclusions consumption of a diet with less favourable Nutri-Score ratings doubles the risk of frailty among community-dwelling older adults. [ABSTRACT FROM AUTHOR]
