Objective:

To systematically review and meta-analyze the prevalence and correlates of sleep-related problems among adults with rheumatoid arthritis (RA) in WHO Eastern Mediterranean Region countries.

Key Findings:

• The pooled prevalence of sleep-related problems among RA patients was 60.9% (95% CI: 56.5%–65.2%).
• Subgroup analyses showed pooled prevalence estimates of 58% for insomnia symptoms, 65% for obstructive sleep apnea-related measures, and 61% for poor subjective sleep quality.
• Depression was the strongest associated factor with sleep-related problems (OR = 2.65), followed by pain (OR = 2.18), fatigue (OR = 1.91), female gender (OR = 1.67), and older age (OR = 1.42).

Interpretation:

Remove the entire section.

Limitations:

• Limited number of contributing countries and studies.
• Substantial heterogeneity in sleep constructs and assessment methods.
• Publication bias assessments were underpowered.

Conclusion:

Revise to state only the findings without recommendations or implications.
