Association between risk factors and Rheumatoid Arthritis: A analysis from NHANES

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder and one of the most prevalent forms of inflammatory arthritis. If left untreated, RA can result in irreversible joint damage, loss of function, long-term disability, and various comorbidities. Despite its clinical significance, the precise etiology of RA remains poorly understood, with current evidence suggesting a multifactorial origin involving genetic, environmental, and lifestyle factors. This study aims to investigate the potential risk factors associated with RA by examining demographic characteristics, including race, gender, and age. In addition, the study explores the impact of dietary factors, particularly salt intake and body weight, on the progression and severity of RA
