To investigate the association between UHR and abdominal aortic calcification (AAC) in people aged≥40.
We used data from the 2013—2014 National Health and Nutrition Examination Survey (NHANES), including a total of 3 008 participants. Multiple logistic regression, subgroup analysis and restricted cubic spline (RCS) analysis were used to explore the correlation between UHR and AAC prevalence.
UHR was positively associated with AAC risk in all participants. Compared with the lowest UHR quartile, the highest quartile had a 134.6% increased risk of AAC (OR=2.346, 95%CI: 1.594-3.453). Interaction analysis showed that there was no significant interaction between UHR grouping and gender or age. Gender stratification showed a 213.6% increase in AAC in the Q4 group of females compared with the Q1 group (OR=3.136, 95%CI: 1.884-5.221), while no statistical significance was achieved in males (P=0.113). Age stratification revealed that for those over 60 years old, the risk of AAC in the Q2, Q3, and Q4 groups increased by 118.6% (OR=2.186, 95%CI: 1.140-4.191), 147.4% (OR=2.474, 95%CI: 1.464-4.181), and 347.8% (OR=4.478, 95%CI: 2.580-7.773) compared with the Q1 group, respectively, while in the 40-60 years old group, it did not reach statistical significance (P=0.338). RCS analysis showed that there was a nonlinear relationship between UHR and AAC.
s UHR is an independent risk factor for AAC, and the higher level of UHR, the higher risk of AAC. The association between UHR and AAC is more significant in females and people over 60 years old.
