Abstract

Juvenile idiopathic arthritis (JIA) is a chronic rheumatic disease and the leading cause of acquired disability in children. A cross-sectional descriptive study was conducted on 126 pediatric patients aged ≤ 16 years old diagnosed with JIA and treated at the Department of Immunology - Allergy - Rheumatology, the Children’s Hospital of Viet Nam, from June 2024 to May 2025. The study aimed to assess nutritional status and investigate associated factors. The majority (89.9%) was children over 5 years old  with a mean age of 9.8 ± 3.6 years old, Most patients had a disease duration of ≥ 2 years (63.5%). The prevalence of undernutrition in the forms of underweight, stunting, wasting, and overweight/obesity was 7.9%, 27%, 9.5%, and 22.2%, respectively. No statistically significant association was found between nutritional status and factors such as age, sex, disease duration, treatment regimen, or clinical subtype. However, stunting, underweight, and overweight/obesity were more common among patients with active disease. A significant association was observed between disease activity and weight-for-age (p = 0.009) as well as weight-for-height z-scores (p = 0.025).
