Low Income Linked to Comorbidities in Rheumatoid Arthritis

Researchers in Korea found data showing that low socioeconomic status in patients with rheumatoid arthritis who were aged 63 years or younger were more susceptible to cardiometabolic risk factors and musculoskeletal disease.

For patients with rheumatoid arthritis (RA) aged <63 years, socioeconomic status (SES) is associated with multiple comorbidities in mental, cardiometabolic, and musculoskeletal systems, according to results published in Rheumatology.

The study included participants with RA from the 2007 to 2015 Korea National Health and Nutrition Examination Survey database (n=1088). The researchers collected SES data on household equivalence income, education, and area of residence. Participants were stratified by median age (63 years) to minimize confounding. The researchers estimated age-adjusted odds ratio (OR), comparing weighted prevalence of comorbidities between low- and high SES groups.

Among participants aged <63 years (mean, 49 years), the researchers found that depression (OR, 2.13; 95% CI, 1.01-4.53), depressive mood (OR, 2.68; 95% CI, 1.54-4.65), suicide ideation (OR, 3.01; 95% CI, 1.79-5.07), diabetes (OR, 3.09; 95% CI, 1.31-7.29), obesity (OR, 2.04; 95% CI, 1.30-3.20), hypertriglyceridemia (OR, 2.36; 95% CI, 1.28-4.34), and osteoarthritis (OR, 2.12; 95% CI, 1.13-3.99) were associated with low income.

They also found that suicide ideation was associated with low education level (OR, 2.25; 95% CI, 1.14-4.44). The results did not indicate any associations between comorbidities and area of residence.

The low SES group had a numerically higher rate of failed access to necessary medical services (23.8%) compared with the high SES groups (18.1%). Among participants aged ≥63 years (mean, 72 years), the researchers did not find any associations between SES and comorbidities.
