Self-reported exercise and bone mineral density in prostate cancer patients receiving androgen deprivation therapy
Bibliographic record
Abstract
PURPOSE: Men with prostate cancer receiving androgen deprivation therapy (ADT) are at increased risk for decreased bone mineral density (BMD). This study evaluates the relationship between self-reported daily activity, endurance and resistance exercise, and BMD measured by dual-energy x-ray absorptiometry (DEXA) in prostate cancer patients receiving ADT. DATA SOURCES: We recruited 96 men treated with ADT for ≥9 months from urology and cancer practices. The Canadian Fitness Survey assessed daily activity and exercise. Data on demographic and lifestyle characteristics and calcium and vitamin D supplementation were collected. Blood was collected for analysis of 25-OH vitamin D. A DEXA scan was performed. CONCLUSIONS: A positive association between endurance exercise and DEXA T-scores of the hip was shown. Regression analysis showed endurance exercise of medium to heavy intensity (measured as energy expenditure in MET-hours/week) was associated with T-scores of the hip (β = 0.048; 95% CI 0.003, 0.112; p = .040) but not with spinal T-scores after controlling for age, body mass index, and alcohol use. IMPLICATIONS FOR PRACTICE: Findings are cross-sectional, but if confirmed in prospective studies suggest that increased endurance exercise is a practical measure nurse practitioners can institute to prevent low bone density in the hip of men treated with ADT.

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.
