Sleep quality, anxiety, depression, and quality of life in rheumatoid arthritis patients and impact of disease activity

Abstract Background Rheumatoid arthritis (RA) is an autoimmune lifelong disease. Systemic manifestations represent a significant aspect of the disease burden. This study aimed to assess sleep quality and psychosocial aspects among RA patients and the impact of disease duration and activity. Results The mean age for included RA patients was 50.00 ± 9.37 years. The median disease duration was 9.50 (Interquartile range (IQR)=5–15) years and 90% of patients were females. Disease activity score 28 was 4.65 ± 1.66. Anxiety and depression were significantly higher among RA participants. Regarding sleep quality assessment, RA group had significantly higher levels of insomnia than the control group (Insomnia Severity Index median (IQR) was 4.5 (0–15) versus 1 (0–3); p value = 0.013) and daytime sleepiness (Epworth Sleepiness Scale median (IQR) was 4 (1–11.25) versus 1 (0–3); p value = 0.002). RA patients showed significantly higher values of Pittsburgh Sleep Quality Index components as well as the global score indicating poor sleep quality. The 36-item short-form health survey domains, representing physical and mental health, were significantly lower among RA cases versus control subjects. Higher disease activity was positively correlated with anxiety, depression, insomnia, sleep quality, sleep efficiency, and daytime dysfunction, while negatively correlated with all domains of the 36-item short-form health survey. Conclusions RA patients have increased anxiety and depression levels in addition to poor sleep quality. High disease activity is linked to increased anxiety and depression levels, impaired quality of life, and poor sleep quality.
