Association between asthma and juvenile idiopathic arthritis in children in the United States: a propensity score weighted cross-sectional study
Authors' conclusion
After adjusting for sociodemographic and environmental confounders, asthma was independently associated with approximately twice the odds of JIA.
Study context
- Population
- Children aged 0–17 years, National Survey of Children’s Health (2016–2021), six cycles, US
- Participants
- 169,786 children
- Exposure

- Asthman = 14,236
- Without asthman = 155,550reference
- Outcome
- Juvenile idiopathic arthritis (JIA) (parent-reported, provider-diagnosed)
Methodological detailspropensity score weighted, generalized boosted modeling, population-based
- Propensity score weighted
- Generalized boosted modeling
- Population-based
