Characteristics and risk factors of rheumatoid arthritis in the United States: an NHANES analysis.

ABSTRACT:

Background

We examined the United States National Health and Nutrition Examination Survey (NHANES) database to determine factors associated with rheumatoid arthritis (RA) in adults 20 to 55 years of age.

Methods

NHANES data collected between 2007 and 2014, excluding the 2011-2012 period, were used. Subjects were divided into those with and without RA. Demographic, clinical, and lifestyle factors were compared between the groups.

Results

After applying inclusion/exclusion criteria, 8,789 persons were included in the study (8,483 without RA, 306 with RA). Multivariable analysis indicated that advanced age (odds ratio [OR] = 1.09, 95% CI [1.07-1.11], P < 0.001), regular smoking (OR = 2.19, 95% CI [1.49-3.21], P < 0.001), diabetes (OR = 2.00, 95% CI [1.35-2.
