Key clinical point: In patients with rheumatoid arthritis (RA), sleep problems are more extensively related to pain and functional impairment than disease duration.
Major finding: The likelihood of having problems with at least 1 or more sleep domains increased slightly with the disease duration (adjusted odds ratio 1.04; 95% CI 1.02-1.07). High-grade pain and high Health Assessment Questionnaire (HAQ) level were associated with increased sleep problems by approximately 3-9-fold and 4-8-fold compared with low-grade pain and low HAQ level, respectively.
Study details: This was an analysis of 4,131 observations from 3,265 patients with newly diagnosed RA whose data on sleep over 12 years from diagnosis were available.
Disclosures: This study was supported by Karolinska Institutet and Reumatikerförbundet. All the authors declared no competing interests.
