The prevalence of frailty varies greatly and has received insufficient attention in developing countries. This study aimed to identify the prevalence of frailty and associated factors among the elderly in Belo Horizonte, Minas Gerais State, Brazil. Clinical, functional, and socio-demographic factors were analyzed. An ordinal regression model was used to verify conditions associated with frailty and to determine odds ratios (α = 0.05). Prevalence rates were 46.3% for prefrailty was 8.7% for weakness. Pre-frail and frail elderly, respectively, showed higher and increasing odds ratios for dependency in instrumental activities of daily living; restrictions in advanced activities of daily living; use of walking aids; comorbidities; falls; depressive symptoms; lower self-efficacy in preventing falls; hospitalization; and advanced age. The study identified a high percentage of frail states associated with higher odds of adverse health conditions, especially related to disability.
Handgrip strength can be a useful tool to identify mobility limitation in clinical practice. Interventions to prevent or minimize impacts of sarcopenia should stimulate physical activity and improvement of body composition in addition to the management of chronic diseases and disabilities.

As mulheres apresentam risco aumentado para a osteoartrite (OA) de joelhos e obesidade. Associadas, essas doenças podem gerar dor e prejuízos funcionais, principalmente em atividades de locomoção. Este estudo visou comparar o impacto do grau de obesidade nos sintomas e capacidade funcional de mulheres com OA de joelhos. Foram selecionadas 13 mulheres obesas (com índice de massa corporal - IMC>30 kg/m²) e 15 com obesidade mórbida (IMC>40 kg/m²), todas com OA bilateral de joelhos. Os sintomas de dor, rigidez e dificuldades funcionais foram avaliados pelo questionário The Western Ontario and McMaster Osteoarthritis Index (Womac). A capacidade funcional foi verificada por quatro testes de velocidade: marcha usual, marcha rápida, subir e descer escadas. Os dois grupos apresentaram um impacto moderado da obesidade na OA de joelhos, sem diferença quanto aos sintomas. As obesas se saíram melhor do que as obesas mórbidas nos testes de marcha usual e subir escadas, mas não nas atividades de marcha rápida e descer escadas, mais complexas e estressantes para a articulação do joelho. Conclui-se que o grau de obesidade não teve impacto nos sintomas de dor, rigidez e dificuldades funcionais associadas à OA de joelhos entre mulheres obesas e obesas mórbidas. E, em dois testes de capacidade funcional, as obesas dos dois grupos tiveram desempenho semelhante, sugerindo que outros fatores podem influenciar o desempenho funcional de obesas com OA de joelhos.
