Physical Activity, Adiposity, and Functional Measures in Youth with Juvenile Idiopathic Arthritis Compared to Healthy Controls
Bibliographic record
Abstract
Objective: To examine habitual physical activity, aerobic capacity, adiposity, and dynamic balance skills in children with JIA, inclusive of knee involvement, compared to age and sex matched healthy controls. Design: Cohort study with a matched-pair design Participants: Twenty-five youth with JIA, ages 10-20, (16 female, 9 male) were matched by age and sex to 25 healthy control participants. Methods: Physical activity data was collected using an ActiGraph accelerometer for 7 days. Aerobic capacity (relative VO2peak) was assessed by a maximal bike test. Adiposity (fat mass index) was evaluated by dual energy X-ray absorptiometry (DXA). Three dynamic balance tests examined balance performance. Results: No significant difference between groups was found in any of the outcomes after adjusting for multiple comparisons. Conclusions: Youth with JIA have similar physical activity, aerobic fitness, adiposity, and functional balance ability as their healthy peers. Differences found in physical activity between male groups could have clinical significance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
