Authors' conclusion

Individuals with RA (vs non-RA) experienced a significantly increased risk for any SD, particularly insomnia. CVD and CVD risk factors, as well as depression and anxiety increased the risk for incident SD in RA. There was no significant association between SD and dementia in RA.

Risk factors for any SD in RA

Obesity, dyslipidemia, presence of cardiovascular disease (CVD), depression, anxiety, and more recent calendar year of RA incidence were associated with increased risk of any SD in RA

Association of SD with dementia in RA

No significant association between SD overall and by subtype with dementia in RA
