- The study explores the non-linear association between the cardiometabolic index (CMI) and Helicobacter pylori (H. pylori) infection.
- Data from the NHANES 1999-2000 survey was used, involving 3357 participants with complete H. pylori serology and CMI data.
- Higher CMI levels were linked to increased odds of H. pylori infection, with a 21% higher odds per standard deviation increase in CMI.
- A non-linear relationship was identified with an inflection point at CMI ≈ 2.8; below this point, CMI increases significantly raised infection risk, but not above it.
- Subgroup analyses showed no significant differences in the association across different populations.
- The study suggests future research should validate these findings in contemporary, longitudinal cohorts.
