Summary: | The scope of this article is to analyze anthropometric indicators as predictors in determining frailty in elderly people. This is a cross-sectional, family-based and analytical study. The survey was composed of 316 elderly subjects. The association between the anthropometric markers and frailty was tested using the Logistic Regression technique. However, the power of frailty diagnosis using anthropometric markers and the identification of the best cutoff points were evaluated using the parameters provided by the Receiver Operating Characteristic (ROC) curve. The anthropometric indicators of nutritional status: calf circumference, body mass index and corrected arm-muscle area are inversely associated with frailty. Thus, an increase in the values of these indicators is a protective factor against this syndrome. Analyzing body mass index and calf circumference simultaneously in order to perform a simpler screening for frail elderly people is recommended, as these indicators show good sensitivity and are easier to measure. Key words Frail Elderly, Anthropometry, Health of the elderly O objetivo deste artigo e analisar os indicadores antropometricos como preditores na determinacao da fragilidade em idosos. Trata-se de um estudo transversal de base domiciliar e analitico. A pesquisa foi constituida por 316 idosos. A associacao entre os marcadores antropometricos e a fragilidade foi testada por meio da tecnica de Regressao Logistica. Ja o poder de diagnostico de fragilidade, utilizando os marcadores antropometricos e a identificacao dos melhores pontos de corte, foi avaliado por meio dos parametros fornecidos pela curva Receiver Operating Characteristic. Os indicadores antropometricos de estado nutricional, Perimetro da Panturrilha, Indice de Massa Corporea e Area Muscular do Braco Corrigida, sao inversamente associados a fragilidade, assim o incremento nos valores desses indicadores e fator de protecao para esta sindrome. Recomenda-se que o Perimetro da Panturrilha e o Indice de Massa Corporea sejam analisados de forma combinada para realizar de forma ainda mais simples a triagem de idosos frageis, ja que possuem boa sensibilidade e tem maior facilidade de mensuracao de seus valores.
