Abstract OBJECTIVE: Although HIV infection has been associated with increased risk of subclinical atherosclerosis and cardiovascular events, peripheral arterial disease (PAD) has not been assessed in HIV-infected patients. The objective of this study was to determine the prevalence of, and risk factors for, PAD using ankle-brachial index (ABI) measurement in HIV-infected and uninfected women. METHODS: ABI was determined for 335 participants in the Women's Interagency HIV Study (WIHS). A cross-sectional analysis was conducted to determine factors associated with high (>or=1.40) ABI. RESULTS: The prevalence of low ABI (or=1.40) was 6.9\% (n=23). The prevalence of low ABI was too low to allow risk factor analysis. On multivariate analysis, factors associated with high ABI were current cigarette smoking [adjusted odds ratio (OR(adj)) 2.53, 95\% confidence interval (CI) 0.99-6.43], being underweight (OR(adj) 11.0, 95\% CI 1.61-75.63) and being overweight (OR(adj) 5.40, 95\% CI 1.13-25.89). CONCLUSIONS: Although the prevalence of ABI or=1.40 was unexpectedly high. Further studies are indicated to determine the clinical significance of high ABI and its relation to the risk of cardiovascular events in HIV-infected women.
