Calf Circumference Is Inversely Associated With Carotid Plaques

Background and Purpose— The association of carotid atherosclerosis with body composition and fat distribution is poorly understood. We aimed to test the cross-sectional association of carotid plaques and common carotid artery intima-media thickness with calf circumference (CC), representing peripheral fat and lean mass, and with waist circumference and waist-to-hip ratio, 2 markers of abdominal obesity. Methods— The study was performed on 6265 subjects aged ≥65 years recruited prospectively from the electoral rolls of 3 French cities. Ultrasound examination and anthropometric measures were performed according to a standardized protocol. Results— Carotid plaques were less frequent with increasing CC, the ORs for the second, third, and fourth quartile of CC compared with the first quartile being 0.98 (95% CI, 0.84 to 1.15), 0.85 (95% CI, 0.72 to 1.01), and 0.71 (95% CI,:0.58 to 0.86; P for trend=0.0002), respectively, independently of age, gender, body mass index, and other vascular risk factors.
