The association between PAD, rates of bone loss, and fracture risk in older men is uncertain.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Methods and Results\u2014<\/jats:italic>\n            <\/jats:bold>\n            We sought to test the hypothesis that PAD is associated with higher rates of bone loss and increased fracture risk. We analyzed data from a prospective cohort study involving 6 US centers and 5781 men at least 65 years of age. We assessed ankle-brachial index and hip bone mineral density, followed up prospectively for changes in hip bone mineral density and fractures. PAD was defined as a baseline ankle-brachial index &lt;0.9. Hip bone mineral density was measured with dual x-ray absorptiometry at baseline and again an average of 4.6 years later. Incident nonspine fractures were ascertained by self-report and confirmed with radiography reports during an average of 5.4 years of follow-up. At baseline, the prevalence of PAD was 6.2%. After adjustment for age, race, site, and baseline bone mineral density, the mean annualized rate of bone loss at the total hip was \u22120.66% per year (95% confidence interval \u22120.78 to \u22120.54) in men with PAD compared with \u22120.34% per year (95% confidence interval \u22120.36 to \u22120.31) in men without PAD (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.001). After further adjustment for multiple potential confounders, the difference was attenuated (\u22120.49% in men with PAD versus \u22120.35% in men without PAD) but remained significant (\n            <jats:italic>P<\/jats:italic>\n            =0.02). Findings were similar at hip subregions. Twelve percent of men with PAD and 7.9% of those without PAD experienced an incident nonspine fracture (hazard ratio adjusted for age, race, and site=1.47, 95% confidence interval 1.07 to 2.04); this association was not altered substantially by further adjustment for multiple confounders.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>Conclusions\u2014<\/jats:italic>\n            <\/jats:bold>\n            In community-dwelling older men, PAD was associated with higher rates of hip bone loss and increased risk of nonspine fractures.
