Associations between anthropometric indices and AS markers
Table 3 shows the correlation among the anthropometric indices and AS markers. Univariate analysis showed that the cf-PWV was positively associated with BMI, WHR, WHtR, ABSI, BRI, waist and neck circumferences, and fat-free mass. cAIx is positively correlated with WHtR, BRI, visceral fat area, and BFM, fat-free mass, and negatively correlated with neck circumferences.
In the regression model, after adjustment for confounders, cf-PWV was positively associated with waist circumferences, WHR, BRI, and WHtR, as shown in Table 4. Also, there was a positive association between cAIx and waist circumferences, WHR, and ABSI. Besides, cAIx was positively associated with the visceral fat area and BFM.
