Objective – To assess the prevalence of intermittent claudication in the aged population of Bambuí, in the State of Minas Gerais, Brazil, and to identify the factors associated with this pathology.
Methods – Population-based cross-sectional study of the aged population (≥ 60 years of age) of Bambuí, whose participants were identified through a census; these participants were interviewed and examined, after they provided written consent. Intermittent claudication was defined based on a standardized World Health Organization questionnaire, which had been tested in developed countries. Analysis of the factors associated with intermittent claudication was performed using multiple logistic regression.
Results – Of the 1,742 elderly living in Bambuí, 1,485 (85.2%) were enrolled in the study. Thirty-seven individuals (2.5%) with intermittent claudication were identified: 28 (1.9%) males and 9 (0.6%) females. Their age brackets were as follows: 16 (1.08%) individuals between 60 and 69 years of age, 17 (1.15%) between 70 and 79 years, and 4 (0.27%) ³ 80 years. A significant association between intermittent claudication and the following characteristics was found: male sex (OR=5.1; CI 2.4-11.0), smokers (OR=3.1; CI 1.2-8.5), ex-smokers (OR=3.4; CI 1.3-8.7), and more than 2 hospital admissions in the last 12 months (OR=2.8; CI 1.1-7.2).
Conclusion - Total prevalence and prevalence according to sex were similar to those found in other countries. The association between intermittent claudication and current or previous smoking strengthens the significance of tobacco in the development and progression of peripheral artery disease. The association of intermittent claudication and a higher number of hospital admissions suggests greater morbidity in the elderly affected.
