Association of Dietary Inflammation Index and Helicobacter pylori Immunoglobulin G Seropositivity in US Adults: A Population-Based Study

Background. Dietary patterns play important role in Helicobacter pylori (H. pylori) infection. We aimed to investigate the potential relationship between Inflammation Index (DII) and H. infection US adults. Methods. This cross-sectional study was based on National Health Nutrition Examination Survey (1999–2000). Individuals aged ≥20 years who provided a 24 hr dietary intake history underwent testing were included analysis. Multivariate weighted logistic regression analysis, smooth curve fitting, subgroup analysis used DII Subgroup analyses demographic clinical variables. Results. There 4,000 individuals enrolled our final The overall mean age 45.92 46.77% males. prevalence of population 45.9%. fitting indicated near-linear pylori. In multivariate odds ratio (OR) is 1.17 (95% confidence interval (CI), 1.09–1.27) for still increased risk independently. Conclusions. levels associated with an among Further studies are needed elucidate exact mechanisms
