FUNDAMENTO: A prevalência de doença arterial periférica (DAP) é elevada entre os idosos. A maioria é assintomática e o exame físico pouco sensível. No Brasil, os fatores associados à DAP em idosos são pouco conhecidos. OBEJETIVOS: Identificar os fatores associados à presença de doença arterial periférica (DAP) em idosos (> 75 anos) da comunidade e desenvolver um escore de predição da doença. MÉTODOS: Estudo transversal, aninhado em uma coorte prospectiva ("Epidoso"). Foram avaliados 176 idosos (> 75 anos) da comunidade. A presença de DAP foi definida por meio do índice tornozelo-braquial 75 anos) da comunidade com alto risco para DAP e que mereceriam investigação mais detalhada.BACKGROUND: The prevalence of peripheral arterial disease (PAD) in the elderly is high. Most are asymptomatic and the sensitivity of the physical exam is low. In Brazil, little is known in regard to PAD risk factors in the elderly. OBJECTIVES: To identify risk factors for PAD among elderly individuals (> 75 years) in the community and to develop a prediction score. METHODS: Cross-sectional, prospective, community-based study nested within a cohort study ("Epidoso"). A total of 176 individuals were assessed. PAD was defined as an ankle-brachial index 18 points defined the "high risk" individuals and yielded sensitivity, specificity, positive predictive value and negative predictive value of 85.9%, 71.4%, 63.2% and 89.9%, respectively. Receiver-operator characteristic analysis yielded area under curve of 85%, indicating excellent discrimination and goodness-of-fit statistics indicated excellent calibration (p=0.639). CONCLUSION: Because of its good performance, the proposed score can become a simple and useful tool to identify elderly community residents at higher risk of PAD who should be considered for further investigation.
