A cross-sectional analysis of data from 28,040 adults in the National Health and Nutrition Examination Survey revealed a significant association between sleep disorders and rheumatoid arthritis. Among participants, 14% reported sleep issues, while 4% were diagnosed with rheumatoid arthritis. Multivariate logistic regression showed that those with sleep disorders had 1.76 times the odds of having rheumatoid arthritis even after adjusting for several demographic and health-related factors. These findings suggest underlying biological mechanisms linking sleep disturbances with rheumatoid arthritis, although limitations of the study prevent causal conclusions.
