Abstract:

Objective To investigate the effect of Osteoporosis Self-Assessment Tool for Asia (OSTA) index on brachial ankle pulse wave velocity (baPWV) and its predictive value for peripheral atherosclerosis in menopausal women. Methods A total of 1 138 menopausal women who underwent physical examination at our hospital from January 2022 to December 2022 were enrolled in the study. General clinical data were collected, the OSTA index was calculated, and baPWV was measured. Patients were divided into the control group (n=539) and the peripheral atherosclerosis group (n=599) according to the baPWV values (peripheral atherosclerosis occurs with baPWV ≥1 400 cm/s). Linear regression and Logistic regression were used to analyze the effect of OSTA index on baPWV in menopausal women. The predictive value of peripheral atherosclerosis was evaluated using the receiver operating characteristic (ROC) curve. Results The OSTA index was lower in the peripheral atherosclerosis group than that in the control group [-0.40 (-2.20, 1.00) vs. 0.40 (-0.60, 1.40), P<0.05]. Univariate linear regression analysis was used to conclude that the OSTA index was an influencing factor of baPWV, and after correcting for risk factors, multivariate linear regression analysis indicated that OSTA index still affected the value of baPWV (P<0.05). The linear regression equation was baPWV= -27.911-39.752×OSTA+6.444×SBP+7.008×DBP+11.506×HCY+27.942×Hs-CRP. Logistic regression analysis suggested that increased OSTA index was a protective factor for peripheral atherosclerosis (OR=0.664, 95%CI: 0.535-0.823, P<0.001). ROC curve analysis suggested that OSTA index was -1.25 as the optimal cutoff point, which predicted peripheral atherosclerosis with an area under the curve of 0.619, a sensitivity of 36.2% and a specificity of 86.3%. Conclusion In menopausal women, OSTA index is an influential factor for baPWV, and increased OSTA index is a protective factor against peripheral atherosclerosis, which can be used to predict baPWV value.
