Background. Peripheral arterial disease (PAD) is a major risk factor for nonhealing foot ulcers in people with diabetes. A number of traditional risk factors have been reported to be associated with PAD; however, there may be a need to consider nontraditional risk factors especially in some vulnerable populations. This study determined the prevalence and risk factors associated with PAD in diabetics. Methods. One hundred and fifty type 2 diabetics and an equal number of age- and sex-matched apparently healthy controls were studied. Assessment of PAD was made using history, palpation of lower limb vessels, and measurement of ankle-brachial index (ABI). Statistically significant differences between categorical and continuous variables were determined using Chi square (χ 2) and Student t-tests, respectively. Regression analysis was done to determine the associated risk factors for PAD. Results. Prevalence of PAD using ABI was 22.0% and 8.0% among diabetic and nondiabetic populations, respectively. Peripheral arterial disease was associated with age, male gender, waist circumference, and high-sensitivity C-reactive protein. Conclusion. This study highlights the high prevalence of PAD in people with type 2 diabetes mellitus and in apparently healthy controls; age, male gender, abdominal obesity, and high hs-CRP values were the associated risk factors.
