Unravelling the link between periodontitis and abdominal aortic calcification in the US adult population: a cross-sectional study based on the NHANES 2013-2014.

ABSTRACT:

Objective

We aimed to explore the association between periodontitis and abdominal aortic calcification (AAC) among a nationally representative sample of US adults.

Design

Cross- sectional study.

Setting

The National Health and Nutrition Examination Survey (2013-2014).

Participants

A total of 2149 participants aged 40 years or older who have complete information for periodontitis and AAC assessment test were included in this study.

Primary and secondary outcome measures

AAC scores can be accurately identified on lateral spine images obtained by dual-energy X-ray absorptiometry, and both the AAC-24 and AAC-8 semiquantitative scoring tools were used for AAC evaluation. Linear regression analysis was used to investigate the relationship between periodontitis and the AAC-8 and AAC-24 scores. Multivariate logistic regression models and reported ORs were used to examine the relationship between periodontitis and AAC.

Results

The prevalence of severe periodontitis combined with severe AAC was 8.49%-8.54%. According to the AAC-8 and AAC-24 score classifications, patients with severe periodontitis had higher odds of severe AAC (AAC-8 score ≥3: (OR: 2.53; 95% CI 1.04 to 6.17) and AAC-24 score >6: (OR: 3.60; 95% CI 1.48 to 8.78)). A positive association between mild-moderate periodontitis and severe AAC was found only when the AAC-24 score was applied (OR: 2.25; 95% CI 1.24 to 4.06). In the subgroup analyses, the likelihood ratio test showed no multiplicative interaction (all p value for interaction >0.05).

Conclusions

The findings showed that periodontitis is associated with an increased risk of severe AAC in the US population aged 40 years and older; this requires further large-scale prospective studies for confirmation.
