Evaluation of dynapenia in the elderly in São Caetano do Sul, São Paulo, Brazil

Abstract Introduction: Aging is characterized by psychological, social, nutritional and biological changes, among which dynapenia stands out. Objective: To analyze the presence of dynapenia and associated factors in elderly people living in the city of São Caetano do Sul. Method: A cross-sectional study was carried out with 295 elderly individuals aged 60 years or older, who were users of public health units in the city of São Caetano do Sul. Dynapenia was assessed by handgrip strength, and its associations were investigated using multivariate logistic regression, according to sociodemographic variables, nutritional status, protein consumption, presence of diseases, and physical activity. Statistical analysis was performed using the IBM-SPSS (Statistical Package for Social Science) software. The adopted level of significance was p < 0.05. Results: Most of the participants were female (n = 251), with mean age of 70.6 years (± 7.0). The presence of dynapenia was observed in 24.07% (n = 71), among which 47 were women (18.73%) and 24 were men (54.55%). Observed associations concerned older age, male sex, lower circumference of the arm and calf, and lower triceps skinfold (p < 0.05). Conclusion: Approximately one-fourth of the elderly studied presented dynapenia, which represents a higher risk of morbidity and mortality. The inclusion of PPF alongside other anthropometric measures for assessing nutritional status is recommended. It is important for public policies to be directed towards health promotion and risk prevention in this age group.
