Abstract
OBJECTIVES: To examine the relationship between characteristics of the physical environment and mobility disability in community-living older persons. DESIGN: Cross-sectional study conducted on three groups of community-dwelling older adults. SETTING: Community-dwelling older people in Seattle, Washington, and Waterloo, Ontario, Canada. PARTICIPANTS: Fifty-four older adults (> or =70) were recruited from two geographic sites and grouped according to level of physical function (elite, physically able, physically disabled). MEASUREMENT: Subjects reported on frequency of encounter versus avoidance of 24 features of the physical environment, grouped into eight dimensions, using a five-point ordinal scale (never, rarely, sometimes, often, always). Never and rarely responses were combined and coded as not encountered or not avoided, whereas the sometimes, often or always responses were combined and coded as encountered or avoided. RESULTS: Disabled older adults reported fewer encounters with and concomitantly greater avoidance of physical challenges to mobility than nondisabled older adults. However, both encounter and avoidance varied by environmental dimension. CONCLUSION: Results support the hypothesis that mobility disability results from an interaction of individual and environmental factors. Mobility disability is associated with avoidance of some, but not all, physically challenging features within the environment, suggesting that some environmental features may disable community mobility more than others.

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 it
