Population-Based Big Data Analysis on Disease Patterns in Patients Identified With Juvenile Idiopathic Arthritis...

Area of Science:

• Rheumatology
• Pediatric Rheumatology
• Epidemiology

Background:

• Juvenile idiopathic arthritis (JIA) is a significant pediatric rheumatic disease.
• Understanding JIA epidemiology is crucial for public health and resource allocation.
• Korean healthcare data offers a unique population-based resource for JIA research.

Purpose of the Study:

• To determine the prevalence and incidence of juvenile idiopathic arthritis (JIA) in Korea.
• To analyze JIA epidemiologic data using national health insurance claims.
• To establish a baseline for JIA in Korea and inform future healthcare strategies.

Main Methods:

• Retrospective analysis of national Health Insurance Review and Assessment Service (HIRA) claims data.
• Inclusion of 1,728 patients diagnosed with JIA (ICD-10 M08, RIDR V133) aged under 16.
• Data analysis from January 1, 2010, to December 31, 2019, including age, gender, prevalence, and incidence calculations.

Main Results:

• Overall JIA prevalence was 15.9 per 100,000 individuals.
• Overall JIA incidence was 2.2 per 100,000 individuals.
• Prevalence and incidence rates were analyzed across different age and gender subgroups.

Conclusions:

• This study presents the first population-based epidemiologic data for JIA in Korea.
• Findings contribute to understanding the JIA burden in Korea and Asia.
• Results will support JIA healthcare planning and policy development.
