In the multivariate regression analysis adjusting for confounding factors, it was observed that for each one-unit increase in the WHR z-score, baPWV increased by 18.1 cm\/s (95%\u2009CI: 7.8 to 28.4). Similarly, for each one-unit increase in the WHtR z-score, baPWV increased by 28.6 cm\/s (95%\u2009CI: 16.6 to 40.6). In the multivariate logistic regression analysis, after fully adjusting for confounding factors, it was found that for every one-unit increase in the WHR z-score, the OR for elevated baPWV was 1.2 (95% CI: 1.1 to 1.4). Similarly, for every one-unit increase in the WHtR z-score, the OR for elevated baPWV was 1.3 (95% CI: 1.1 to 1.5). According to the generalised additive model, we found that WHR and WHtR were positively correlated with baPWV and elevated baPWV. Subgroup analysis revealed that elevated WHR and WHtR are significant predictors of AS, with this association being substantially amplified by poor glycaemic control (glycated haemoglobin
