Level and correlates of physical activity among children and adolescents with juvenile idiopathic arthritis compared to controls: results from a German nationwide prospective observational cohort study
Authors' conclusion
Depending on JIA category, children and adolescents with JIA were similarly or even more likely to achieve the WHO recommended minimum level of PA compared to general population controls.
Study context
- Population
- Children and adolescents aged 3 to 17 years with juvenile idiopathic arthritis (JIA) and population controls, Germany, data from 2017 (mean age 11.2 ± 4.2 years, female 67%)6,297 matched-pairs
- Exposure
- Children and adolescents with JIA vs general population controls
- Outcome
- Achievement of the WHO recommended amount of PA (self-reported)
Methodological detailsnationwide, age- and sex-specific pairwise (matched) analyses, linear regression model
- Nationwide
- Age- and sex-specific pairwise (matched) analyses
- Linear regression model
Main finding
As reported in the abstract
Achieved WHO recommended amount of PA, aged 3-17 years
Observational data: associations, not effects.
Further findings
- Achieved WHO recommended amount of physical activity (PA), patients aged ≥ 12 years — JIA
- 18%
Achieved WHO recommended amount of PA, patients aged ≥ 12 years
- PA steadily decreased with age and varied between JIA categories
- Female adolescents and patients with enthesitis-related arthritis least likely to achieve minimum recommended PA
Correlates of physical inactivity among patients (linear regression)
- Associated with female sex, higher age at disease onset, longer disease duration, more functional disability (C-HAQ) and higher disease activity (cJADAS-10)
