Physical activity and depressive symptoms after breast cancer: Cross-sectional and longitudinal relationships.
Bibliographic record
Abstract
OBJECTIVE: The objective of this study was to examine the cross-sectional and longitudinal relationships between moderate-to-vigorous intensity physical activity (MVPA) and depressive symptoms in women after treatment for breast cancer. METHOD: Accelerometer data on MVPA and self-report data on frequency of depressive symptoms were collected five times at ∼ 3-month intervals from women (Mage at Time 1 = 55.01 ± 10.96 years) who had completed treatment for breast cancer 3 months prior to study inception. Data were analyzed using latent growth modeling with structured residuals. RESULTS: Levels of MVPA decreased, on average, by .52 min every 3 months (p < .001), whereas the frequency of depressive symptoms was stable. MVPA was inversely and significantly related cross-sectionally with depressive symptoms, but not longitudinally. Also, there was no evidence of a bidirectional predictive relationship between MVPA and depressive symptoms. CONCLUSION: Although higher levels of MVPA were associated with less frequent depressive symptoms cross-sectionally in women after treatment for breast cancer, MVPA did not predict frequency of depressive symptoms or vice versa. Common etiologic or shared risk factors underpinning the cross-sectional relationships between depressive symptoms and MVPA should be studied across the transition from treatment to survivorship.

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.
