Frequency of protein-rich food consumption and incidence of sarcopenia in older adults: Health, Well-being, and Aging Study (SABE), São Paulo

Abstract

Objective To investigate the association between protein-rich food consumption and the risk of developing dynapenia and sarcopenia over fi e years. Methods This longitudinal study used data from older adults (≥60 years old) in São Paulo, collected in 2010 and 2015 as part of the Health, Well-being, and Aging Study. A total of 519 participants were analyzed, and the classifi of dynapenia and sarcopenia was based on handgrip strength and the muscle mass index, respectively. The frequency of protein-rich food consumption was categorized and analyzed regarding the incidence of dynapenia and sarcopenia using binary logistic regression models, considering odds ratio and 95% confi intervals. Results The incidence of dynapenia and sarcopenia was, respectively, 22% and 1.1% among participants. Analysis showed that individuals with daily consumption of meat and legumes had the lowest risk of developing these conditions. Daily meat consumption alone also reduced the risk. Conclusion Frequent consumption of meat and legumes is associated with a lower risk of developing dynapenia and sarcopenia in older adults. Combining these foods rich in animal and plant proteins offers signifi t benefi for muscle health.
