Association between dietary inflammatory potential and rheumatoid arthritis: Evidence from the NHANES 2003 to 2018.

ABSTRACT: Rheumatoid arthritis (RA) affects approximately 17.6 million people globally. While genetic factors contribute to RA development, dietary patterns may influence disease onset and progression. This study investigated the relationship between dietary inflammatory potential and RA prevalence using data from 25,137 adults (≥20 years) in the National Health and Nutrition Examination Survey (NHANES) 2003 to 2018. Dietary inflammatory potential was assessed using the dietary inflammatory index (DII) and energy-adjusted DII (E-DII). RA status was based on self-reported physician diagnosis. Weighted logistic regression models were used. Participants with RA had significantly higher DII (1.11 ± 1.53 vs 0.76 ± 1.61) and E-DII (0.95 ± 1.26 vs 0.67 ± 1.16) scores compared to those without RA. In fully
