Abdominal Aorta Calcification Identified on DXA Scans and the Risk of Mortality in Adults.

ABSTRACT:

Background

Abdominal aortic calcification (AAC) on lateral lumbar radiographs increases the risk of cardiovascular events and mortality. However, data on the association between AAC detected in dual energy X-ray absorptiometry (DXA) and the risk of mortality in the general population are scarce.

Methods

The present study was based on data from participants aged ≥40 years in the National Health and Nutrition Examination Survey (NHANES) cycle of 2013 to 2014. Vertebral assessment of lateral spine DXA scans was used to provide AAC measurements at vertebrae L1-L4. The extent of AAC was defined according to the Kauppila AAC-24 scores (0-1, 2-5, ≥6), and the NHANES 2019 public-use linked mortality files were used to assess mortality status.
