Physical activity in daily life: A new outcome to evaluate young adult survivors of bronchopulmonary dysplasia?
Bibliographic record
Abstract
Background: Bronchopulmonary Dysplasia (BPD) is considered one of the most common chronic lung diseases in children. Interestingly, recent evidence has suggested important similarities between COPD and BPD regarding lung function impairments, but evidence on the extra-pulmonary complications of BPD is still lacking. Therefore, this study aims to evaluate the profile of physical activity in daily life (PADL) in young adults survivors of BPD and compare it with public guidelines for PA. Methods: This is a substudy of a large cohort study being conducted in the province of Quebec, Canada; investigating the long term consequences of adults who were born prematurely between 1993 and 1997. Study participants were submitted to assessments of lung function (spirometry); maximal and submaximal exercise capacity (incremental peak and endurance cycling test), as well as PADL using an activity monitor (SenseWear Armband) for one week. Results: Preliminary results of this study include 11 subjects with BPD (mean (SD): age, 22.5 (1.6) yrs; BMI: 26.5 (8.5) kgm2; gestational age, 27.9 (3.6) weeks; birth weight, 1.12 (0.5kg); FEV%pred: 75(6.8) %pred. In addition, results from activity monitoring showed that BPD subjects in this study walked an average of of 8500 (3596) steps/day and spent 127 (94) minutes in activities of moderate intensity (>3METS). Conclusion: Our results suggest that young adults survivors of BPD are insufficiently active in daily life according to guidelines recommendations of performing at least 150 minutes of moderate PA or walking a minimum of 10000 steps/day. Hence, PADL may be an interesting outcome to evaluate subjects with BPD and may not be overlooked.

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.
