Association between sleep disorders and rheumatoid arthritis in U.S. adults.

ABSTRACT:

Background

Evidence on the association between sleep disorders and rheumatoid arthritis (RA) remains limited. This study aimed to investigate this relationship in U.S. adults using data from the National Health and Nutrition Examination Survey (NHANES).

Methods

This cross-sectional study included adults aged ≥ 18 years from the 2005-2018 NHANES cycles. A total of 28,040 participants were included. Weighted multivariate logistic regression models were employed to assess the association between sleep disorders and RA. Three models were constructed: an unadjusted model, a minimally adjusted model controlling for demographic variables, and a fully adjusted model incorporating additional lifestyle and clinical covariates. Subgroup analyses were performed to assess the consistency
