The relationship between novel anthropometric indices, specifically a body shape index (ABSI) and body roundness index (BRI), with abdominal aortic calcification (AAC) or severe AAC (SAAC) is unclear. The aim of our study was therefore to investigate possible relationships between novel anthropometric indices and prevalence of AAC and SAAC.
We obtained U.S. general population data from the National Health and Nutrition Examination Survey between 2013 and 2014. The study used restricted cubic spline (RCS) analysis, multivariable logistic regression modeling, subgroup analysis, and receiver operating characteristic (ROC) curve assessment. We investigated relationships between ABSI or BRI and AAC and SAAC risk. Associations between ABSI or BRI and the degree of AAC were also evaluated using a generalized additive model.
The study cohort was comprised of 1062 individuals. The RCS plots revealed a U-shaped curve associating ABSI with AAC risk. A similar trend emerged for SAAC, where the risk initially increased before subsequently decreasing with rising ABSI levels. Additionally, BRI exhibited a positive correlation with both AAC and SAAC risk. As ABSI and BRI values increased, the degree of AAC also increased. In ROC analysis, ABSI displayed a significantly larger area under the curve compared to BRI.
ABSI is associated with AAC prevalence following a U-shaped curve. Additionally, BRI is positively correlated with AAC risk. ABSI demonstrates a superior discriminative ability for AAC compared to BRI. Therefore, maintaining an appropriate ABSI and BRI may reduce the prevalence of AAC.
新型人体测量指数，特别是体型指数（ABSI）和身体圆润度指数（BRI）与腹主动脉钙化（AAC）或严重腹主动脉钙化（SAAC）之间的关系尚不清楚。因此，我们研究的目的是调查新型人体测量指数与AAC和SAAC患病率之间的可能关系。
我们从2013年至2014年的美国国家健康与营养检查调查中获取了美国普通人群数据。该研究采用了受限立方样条（RCS）分析、多变量逻辑回归建模、亚组分析和受试者工作特征（ROC）曲线评估。我们调查了ABSI或BRI与AAC和SAAC风险之间的关系。还使用广义相加模型评估了ABSI或BRI与AAC程度之间的关联。
研究队列由1062名个体组成。RCS图显示ABSI与AAC风险呈U形曲线相关。SAAC也出现了类似趋势，即风险最初随着ABSI水平的升高而增加，随后下降。此外，BRI与AAC和SAAC风险均呈正相关。随着ABSI和BRI值的增加，AAC程度也增加。在ROC分析中，ABSI的曲线下面积显著大于BRI。
ABSI与AAC患病率呈U形曲线相关。此外，BRI与AAC风险呈正相关。与BRI相比，ABSI对AAC具有更好的判别能力。因此，保持适当的ABSI和BRI可能会降低AAC的患病率。
