Correlations between anthropometric parameters and carotid elasticity by real-time vascular quantification / 中国医师杂志

ABSTRACT

Objective:This study aimed to investigate the relationships between anthropometric parameters and carotid elasticity by real-time vascular quantification stiffness technique (R-VQS), and to identify the predictive value of anthropometric parameters for cardiovascular disease risk.Methods:A total of 563 adults were recruited for this study and were divided into two groups by gender. The anthropometric indices [body mass index (BMI), waist circumference (WC), a body shape index (ABSI), body round index (BRI), and visceral adiposity index (VAI)] were calculated. R-VQS technique was used to assess the parameters of carotid elasticity pulse wave velocity (PWV). The correlations between the anthropometric indices and PWV were analyzed. Linear regression was used to analyze the predictive factors of PWV.Results:⑴ The BMI, WC, ABSI, BRI, VAI and PWV were higher in men than those in women ( P<0.05); ⑵ In men and women, all the anthropometric parameters positively correlated with systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol (TC), triglycerides (TG), and negatively correlated with high-density lipoprotein (HDL) ( P<0.05); ⑶ diabetes mellitus (DM) and hypertension history were predictors of PWV in men ( β=0.110, 0.101, respectively, P<0.05); DM, hypertension history and smoking status were predictors of PWV in women ( β=0.061, 0.095, 0.067, respectively, P<0.05); ⑷ After adjusting for diabetes, hypertension and smoking, ABSI and VAI were predictors of PWV in men ( β=0.078, 0.068, P<0.05); BMI, WC, ABSI, BRI and VAI were predictive factors of carotid PWV in women ( β=0.131, 0.123, 0.204, 0.153, 0.196, P<0.05). Conclusions:Among the anthropometric indexes, ABSI and VAI have good correlations with carotid elasticity in wen and women, represented by PWV. These results suggest that ABSI and VAI may be convenient, highly cost-effective and simple parameters for obesity and are associated with cardiovascular disease (CVD) risk in clinical practice. R-VQS is a convenient, real-time and rapid technique for the early assessment of the carotid elasticity.
