Link between sleep disorders, rheumatoid arthritis may exist

Investigators may have uncovered the relationship between sleep disorders and the risk of rheumatoid arthritis.

In a cross-sectional study published in Arthritis Research & Therapy, the investigators used 2005 to 2018 data from the National Health and Nutrition Examination Survey to explore whether sleep disorders may be associated with rheumatoid arthritis in a group of more than 28,000 adult participants.

The investigators found that about 14% and 4% of the study population had sleep disorders and rheumatoid arthritis, respectively. After adjusting for demographic factors, they found a strong correlation between sleep disorders and the risk of rheumatoid arthritis.

Despite the findings, the investigators emphasized that they could not establish a causal relationship between the conditions. Further studies are needed to better understand the mechanisms underlying the connection identified in the study.
