Prevalence and predictors of peripheral arterial disease determined by ankle brachial index in diabetes population treated within primary care services in a non-urban area of lower northern Thailand

In diabetes patients, urban lifestyle has been concerned as one of the risk factors for peripheral arterial disease (PAD). The aims of this study were to find out the prevalence and associated risk factors of PAD in type 2 diabetes patients who live in a non-urban community area. A total of 885 participants with type 2 diabetes mellitus were enrolled from six primary care units in the health network centered at Naresuan University Hospital, Phitsanulok, between May and June 2018. Ankle-brachial index (ABI) was performed in all subjects using a vascular screening device. PAD was defined by an ABI value of 0.9 or lesser at least on one leg. The predictors of PAD were analyzed using multiple logistic regression. The prevalence of PAD was 7.2% among 884 evaluable patients. Diabetic neuropathy and a history of macrovascular complications were significant predictors of PAD.
