Associations between physical activity, socioeconomic and sociodemographic factors, and risk of sarcopenia in older adults in Northeast Brazil

Our findings demonstrate the importance of promoting physical activity and reducing social inequalities to prevent sarcopenia in aging populations. Public health strategies should be tailored to account for both behavioral and social determinants of health, with particular attention to the intersection of sex, social support, and occupation. Further longitudinal research is needed to clarify how these factors interact over time in the development of sarcopenia.
