Determinants of physical activity in older adults: an umbrella review protocol
Bibliographic record
Abstract
OBJECTIVE: The aim of this review is to summarize the evidence for determinants of physical activity in older adults. INTRODUCTION: Physical activity is an important predictor of multi-morbidity, falls, and cognitive decline in older adulthood. Understanding what influences older adults' physical activity behavior is an important first step for guiding effective interventions for promoting physical activity in this population. INCLUSION CRITERIA: This umbrella review will include systematic reviews (including scoping reviews) reporting on the relationship between determinants (also referred to as correlates or factors), measured by either self-report or direct measurement, and physical activity in adults ≥60 years. METHODS: A systematic search of six databases will be completed in MEDLINE, Embase, CINAHL, Cochrane Library, PsycINFO, and AgeLine. Two independent reviewers will screen titles, abstracts, and full-text articles, and perform data extraction and quality assessment. Evidence for determinants of physical activity will be synthesized using the socio-ecological model. If possible, evidence will be compared by study design, type of physical activity, outcome measure used, setting, and sex. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42020159332.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
