Juvenile Idiopathic Arthritis, Earnings, and Work Loss: A Nationwide Matched Cohort Study
Main finding · Annual earningsResult — go to the resultMean annual difference -€736 95% CI -€1,026 to €445Authors' conclusion
Patients with JIA had lower mean annual earnings and higher work loss than matched general population comparators, but earnings differences diminished in magnitude with age and work loss diminished with calendar period of identification.
Study context
- Population
- Individuals with juvenile idiopathic arthritis (JIA) identified in the Swedish National Patient Register (2001–2017) and matched general population comparators; earnings and work loss from age 18 yearsmedian 11 years' follow-up
- Participants

- Exposure
- JIA vs matched general population comparators
- JIAn = 4,737

- Outcome
- Earnings and work loss
Methodological detailsnationwide, register-based, individually matched to up to five general population comparators on birth year, sex, and residence county, linear regression adjusted for sex, age, age at identification, calendar year, parental education, work loss and earnings
