ESTUDO NACIONAL DE PREVALÊNCIA E FATORES ASSOCIADOS À DINAPENIA EM IDOSOS COM INSUFICIÊNCIA RENAL CRÔNICA

Abstract

Objective: To determine the prevalence of dynapenia and identify associated factors in older adults with acute renal failure (AKI). Methodology: Cross-sectional study using the ELSI-Brazil baseline (2015-2016), sampling 427 individuals (≥50 years old) self-reported CRF. Independent variables included sociodemographic characteristics, lifestyle, and health conditions. Dynapenia was evaluated by the Palmar Pressure Strength test. Results: The prevalence of dynapenia was 33.2%. Bivariate analysis revealed a significant risk with advanced age (PR: 2.70; 95%CI: 1.76-4.14; p < 0.001), poor/very poor self-rated health was a risk factor (PR: 1.62; 95%CI: 1.01-2.59; p = 0.044) and diabetes (PR: 2.13; 95%CI: 1.58-2.89; p < 0.001), while leisure-time physical activity was protectively associated (PR: 0.71; 95%CI: 0.53-0.95; p = 0.021). In the multivariate analysis, only advanced age (≥80 years; PR: 2.25; 95%CI: 1.50-3.38; p < 0.001) and diabetes remained significant (PR: 1.94; 95%CI: 1.41-2.67; p < 0.001). Conclusion: Three out of 10 older adults had dynapenia. Elderly people ≥80 years of age and with diabetes are at increased risk for the occurrence of dynapenia.
