OBJECTIVE: We aimed at determining the relationship between sleep disorders and daily activity and quality of life (QoL) of patients with rheumatoid arthritis (RA).

MATERIALS AND METHODS: A systematic search of databases was carried out. We used the Cochrane guidelines to perform the meta-analysis following the PRISMA statement. Fifteen full-text papers were ultimately included in the subsequent statistical analyses. The study was registered in the PROSPERO database (No. CRD42021245664).

RESULTS: In group 1, the mean sleep quality score measured with the Pittsburgh Sleep Quality Index (PSQI) was 6.93. The mean QoL score for the physical domain and the mental domain of the Short Form (36) Health Survey (SF-36) was 38.15 and 41.83, respectively. In group 2, the mean PSQI score was 7.21. The mean daily activity score measured with the Health Assessment Questionnaire (HAQ) was 0.80. A strong negative correlation was observed between the PSQI scores, and the SF-36 total score each unit increase in the SF-36 total score was associated with an average decrease of 0.35 points in the PSQI score. A one-point increase in the PSQI score was associated with an average decrease of 2.4 points in the QoL score measured with SF-36.

CONCLUSIONS: RA patients have a low quality of sleep. Sleep disorders correlate negatively with the QoL scores in the physical and mental domains.
