Brachial-ankle pulse wave velocity (baPWV), a direct measure of aortic stiffness, has increasingly become an important assessment for cardiovascular risk. The aim of the present study was to establish the reference and normal values of baPWV in the Central Asia population in XinJiang, China.
We collected participant data from the Cardiovascular Risk Survey study in XinJiang, China. We performed multiple regression analysis to investigate the determinants of baPWV. The median and 10th-90th percentiles were calculated to establish the reference and normal values according to these categories.
In total, 5,757 Hans participants aged 15-88 years old were included in the present study. The Spearman correlation analysis showed that age (r = 0.587, p < 0.001) and mean blood pressure (MBP, r = 0.599, p <0.001) were the major factors influencing the values of baPWV in the reference population. Furthermore, in the multiple linear regression analysis, the standardized regression coefficients of age (0.445) and MBP (0.460) were much higher than those of BMI, TG, and glycemia (-0.054, 0.035, 0.033). In the covariance analysis, after adjustment for age and MBP, only diabetes was a significant independent determinant of baPWV (p = 0.009). So participants with diabetes were excluded from the reference value population. The reference values ranged from 14.3 m/s to 25.2 m/s and the normal values ranged from 13.9 m/s to 21.2 m/s.
This is the first study that has established the reference and normal values for baPWV according to age and blood pressure in the Central Asia population.
