Association between Life's Essential 8 and rheumatoid arthritis

Rheumatoid arthritis (RA) exhibits a robust association with cardiovascular disease. Our study aims to elucidate the correlation between RA prevalence and Life's Essential 8 (LE8), a recently updated measure of cardiovascular health (CVH).

We conducted a population-based cross-sectional study using data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2007 to 2018. Utilizing multivariable logistic and restricted cubic spline models, we explored the relationship between LE8 and RA. Our analysis included 17,263 participants. We found that higher LE8 scores were closely associated with reduced odds of RA (odds ratio for each 10-point increase, 0.91 (95% CI, 0.75-0.87)). Furthermore, we observed a nonlinear association between LE8 and RA after adjusting for potential confounders. Specifically, higher scores for sleep health, nicotine exposure, body mass index, and blood pressure within the LE8 components were significantly correlated with a lower risk of RA. Additionally, the inverse relationship between LE8 scores and RA was notably stronger among young and female individuals.

Our findings suggest a negative correlation between LE8 and RA prevalence, indicating that adherence to the lifestyle defined by LE8 may confer protective effects against RA.
