Abstract
Abstract Background and aims: It is uncertain whether neck circumference can be a risk indicator for subclinical atherosclerosis. We aimed to investigate their relationships measured by coronary artery calcium (CAC) and common carotid intima-media thickness (cc-IMT) with neck circumference in ELSA-Brasil. Methods and results: In cross-sectional and sex-specific analyses of 2266 women (50.6 8.4 yrs) and 1886 men (50.7 9.0 yrs) with both cc-IMT and CAC, free from previous cardiovascular disease a ...
Abstract Background and aims: It is uncertain whether neck circumference can be a risk indicator for subclinical atherosclerosis. We aimed to investigate their relationships measured by coronary artery calcium (CAC) and common carotid intima-media thickness (cc-IMT) with neck circumference in ELSA-Brasil. Methods and results: In cross-sectional and sex-specific analyses of 2266 women (50.6 8.4 yrs) and 1886 men (50.7 9.0 yrs) with both cc-IMT and CAC, free from previous cardiovascular disease at baseline, we built logistic models using diverse cut-off points for CAC score (0 vs >0, <100 vs 100, <400 vs 400 Agatston units) and cc-IMT (<75th percentile vs 75th; <90th percentile vs 90th) as dependent variables, after which adjustments for age and traditional cardiovascular risk factors were made. Mean neck circumference was 33.6 ( 2.4 cm) for women and 38.8 ( 2.6 cm) for men. In fully adjusted models including sociodemographic, cardiovascular risk factors and body-mass index and waist circumference, for each 1 standard deviation increase in neck circumference we found an odds ratio (OR, 95% CI) for IMT above the 75th percentile of (1.52, 1.16; 1.99) for women and (1.66, 1.28; 2.14) for men, and above the 90th cc-IMT percentile [1.66 (1.19; 2.32) for men but not for women [1.21 (0.80; 1.82)].We found no association between neck circumference and CAC using different cut-off points (p > 0.05 for all). Conclusion: Neck circumference was significantly and independently associated with cc-IMT but not with CAC in women and men, indicating a possible effect of perivascular fat tissue on atherosclerosis. ...
