Objective: To examine which atherosclerotic risk factors are determinants for peripheral arterial disease (PAD), we performed a population-based study in 6450 subjects (40% men, 60% women) aged 55 years and older. Methods: The presence of PAD was assessed by measuring the ankle-arm systolic blood pressure index (AAI); PAD was considered present if the AAI was lower than 0.90 in either leg. In addition, a threshold AAI of 0.70 in either leg defined severe PAD. Results: Determinants strongly and independently associated with PAD were age of at least 75 years (odds ratio [OR], 1.2; 95% confidence interval [Cl], 1.0-1.6), fibrinogen level (OR, 1.5; 95% Cl, 1.3-1.7), cigarette smoking (OR, 2.8; 95% Cl, 2.3-3.4), diabetes mellitus (OR, 2.0; 95% Cl, 1.6-2.5), and systolic blood pressure (OR, 1.2; 95% Cl, 1.1-1.2). An inverse relation of high-density lipoprotein cholesterol level with PAD (OR, 0.7; 95% Cl, 0.5-0.8) was found. Similar results were demonstrated for severe PAD. Separate analyses for men and women did not demonstrate differences in risk factors for PAD. Conclusions: Assessment of a wide range of atherosclerotic risk factors enabled us to quantify the relative importance of each factor as determinant for PAD. In total, 69% of the occurrence of PAD is attributable to cardiovascular risk factors measured in our study; smoking accounted for most (etiologic fraction, 18.1%). The results suggest that preventive management of PAD should be directed at systolic blood pressure, fibrinogen level, smoking, high-density lipoprotein cholesterol level, and diabetes mellitus.
