Body mass index is associated with health-related quality of life and disease characteristics in young adults with juvenile idiopathic arthritis
Authors' conclusion
We discovered that BMI was significantly related to HRQoL, disease activity, and disability.
Study context
- Population
- Young adults with juvenile idiopathic arthritis (JIA), newly diagnosed and recruited consecutively 1997–2000 in specific regions in the Nordic countries, seen at the 18-year follow-up visit72% female
- Participants
- 355 adults
- Exposure
- Body mass index (BMI) groups
- Outcome
- Impact of BMI on HRQoL (SF-36), disease activity and disability
- Follow-up
- 18-year follow-up
Methodological detailssub-study of the population-based Nordic JIA cohort study, 18-year follow-up visit, adjusted for sex, age, and JIA subtype
- Sub-study of the population-based Nordic JIA cohort study
- 18-year follow-up visit
- Adjusted for sex, age, and JIA subtype
Main finding
As reported in the abstract
Relationship of BMI with JIA category, disease activity, disability, pain, fatigue, sleep quality and HRQoL
- JIA categories vs BMI groups, significant relationship
- p = 0.014
- BMI vs disease activity scores (DAS28), significant relationship
- p = 0.028
- BMI vs disability, significant relationship
- p < 0.001
- BMI vs pain, significant relationship
- p = 0.013
- BMI vs fatigue, significant relationship
- p = 0.035
- BMI vs sleep quality, significant relationship
- p = 0.044
- BMI vs health-related quality of life (HRQoL) bodily pain, significant relationship (adjusted for sex, age, JIA subtype)
- p = 0.010
- BMI vs HRQoL general health, significant relationship (adjusted for sex, age, JIA subtype)
- p = 0.048
Observational data: associations, not effects.
