No association between rheumatoid arthritis and cognitive impairment in a cross-sectional national sample of older U.S. adults.

ABSTRACT:

Background

Studies suggest an increased prevalence of cognitive impairment (CI) among people with rheumatoid arthritis (RA). However, most prior studies have used convenience samples which are subject to selection biases or have failed to adjust for key confounding variables. We thus examined the association between CI and RA in a large national probability sample of older US adults.

Methods
