The relationship between a body shape index and abdominal aortic calcification: a population-based study

Area of Science:

• Cardiovascular Health
• Anthropometry
• Radiology

Background:

• Abdominal Aortic Calcification (AAC) is linked to visceral adiposity.
• The relationship between Body Shape Index (ABSI) and AAC requires further investigation.

Purpose of the Study:

• To examine the association between ABSI and AAC.
• To compare the predictive performance of ABSI against other anthropometric measures for AAC.

Main Methods:

• Utilized data from the 2013–2014 National Health and Nutrition Examination Survey (NHANES).
• Employed weighted multivariable regression, subgroup analysis, and ROC curves.
• Assessed ABSI, Weight-adjusted Waist Index (WWI), BMI, WHtR, and WC for predicting AAC and SAAC.

Main Results:

• A higher ABSI correlated with increased AAC scores and risk of Severe Abdominal Aortic Calcification (SAAC).
• ABSI showed a nonlinear positive association with AAC and SAAC.
• ABSI outperformed WWI, BMI, WHtR, and WC in predicting AAC and SAAC.

Conclusions:

• ABSI is positively associated with AAC and SAAC.
• Prospective studies are needed to confirm these findings.
