Objectives:To estimate the prevalence of sarcopenia, dynapenia, and sarcodynapenia and associated factors in older adults in the city of São Paulo, Brazil.Methods:A population-based, cross-sectional study was conducted with 1,168 older adults who participated in the third wave of the Health, Well-being, and Aging study in 2010 (SABE study). Men and women with skeletal muscle mass ≤ 8.90 and ≤ 6.37 kg/m2, respectively, were considered sarcopenic. Men and women with grip strength < 30 and < 20 kg, respectively, were considered dynapenic. Those with both conditions were considered sarcodynapenic. Sociodemographic, behavioral, clinical, nutritional, and biochemical characteristics were investigated as factors associated with each of the three conditions using multinomial logistic regression.Results:Theprevalence of sarcopenia, dynapenia, and sarcodynapenia was 4.8% (95%CI 3.6 - 6.3), 30.9% (95%CI 27.5 - 34.6) and 9.0% (95%CI 7.2-11.3), respectively. An increase in age and malnutrition was associated with all the three conditions. Cognitive impairment was associated with both dynapenia and sarcodynapenia. Schooling, current smoking habit, and not having a marital life were associated with sarcopenia. Osteoarthritis, schooling, being an ex-smoker, and low hemoglobin were associated with dynapenia. Smoking habit and the risk of malnutrition were associated with sarcodynapenia.Conclusion:Dynapenia is more prevalent among older adults, followed by sarcodynapenia, and sarcopenia. With the exception of age, schooling, and malnutrition, the factors associated with sarcopenia and dynapenia are different. However, there are similarities in some associations regarding the presence of sarcodynapenia.
