Abstract

OBJECTIVES:
To assess whether public healthcare attendance associates with altered atherosclerotic cardiovascular disease risk in established rheumatoid arthritis (RA).
METHODS:
We determined disparities in major conventional (hypertension, dyslipidemia, smoking and diabetes), other conventional (underweight, obesity, metabolic syndrome, chronic kidney disease, alcohol use, tension, depression and body height) and non-conventional (current and cumulative inflammation markers) cardiovascular risk factors between 424 consecutive public and 202 private healthcare patients in mixed regression models.
RESULTS:
Eighty-one percent of public healthcare patients were black (67%) or caucasian (14%) and 83% of private healthcare cases were caucasian. Seventy percent of the patients had ≥1 major conventional risk factor. After adjustment for age, gender, ethnic origin and statin use when appropriate, public healthcare attendance associated with the prevalence of hypertension (odds ratio (OR) [95%CI]=1.72 [1.03, 2.85]), having ≥1 major conventional risk factor (OR [95%CI]=1.83 [1.09, 3.07]) and an increased mean (SD) number of such risk factors (p=0.03), metabolic syndrome frequency (OR [95%CI]=1.90 [1.07, 3.40]), alcohol use (OR [95%CI]=0.07 [0.03, 0.18]), shorter stature (p<0.0001), higher tension (p=0.02) and depression score (p<0.0001) and higher inflammatory markers including the disease activity score in 28 joints (p=0.005), C-reactive protein concentration (p=0.0006), Health Assessment Questionnaire disability index (p<0.0001), and number of deformed joints (p<0.0001). In sensitivity analyses performed in caucasian Africans, public healthcare attendance associated with increased frequencies of each major conventional risk factor (OR=2.06 to 3.69) and higher other conventional and non-conventional mediated cardiovascular risk.
CONCLUSIONS:
Public healthcare patients with established RA experience markedly enhanced conventional and non-conventional cardiovascular risk burdens.
