Association between Cancer Risk and Behaviors Adherent to Cancer Prevention Recommendations in Ontario, Canada.
Bibliographic record
Abstract
PURPOSE: In 2007, the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) published several diet and physical activity recommendations to reduce cancer risk. Our objective was to examine the association between self-reported behaviors consistent with the WCRF/AICR recommendations and the risk of developing any cancer and colorectal cancer in Ontario. METHOD: 111,139 Ontarians who completed the Canadian Community Health Survey (2000-2008) were linked to the Ontario Cancer Registry to determine whether they were diagnosed with cancer. Their responses were used to assess behaviors consistent with 4 WCRF/AICR recommendations (body fatness, physical activity, vegetable and fruit consumption, and alcoholic drinks). Multivariate Cox proportional hazard regression models were used to assess the association between adherence to the 4 WCRF/AICR recommendations and subsequent cancer risk. RESULTS: Among the 111,139 participants, 8,942 (8%) were diagnosed with cancer with a mean follow-up of 9.6 years. Compared to not meeting any of the selected WCRF/AICR recommendations (composite score, 0), participants who were most adherent to the selected WCRF/AICR recommendations (composite score, 4) were 31% less likely to develop any cancer (HR, 0.69; 95% CI, 0.51-0.92) and were 61% less likely to develop colorectal cancer (HR, 0.39; 95% CI, 0.20-0.77) after adjusting for some potential confounding factors. When stratified by sex, the associations remained statistically significant for men, but not for women. In addition, increasing vegetable and fruit consumption, having lower body fatness, and decreasing alcohol consumption were each associated with reduced risk of both any cancer and colorectal cancer. CONCLUSION: Healthy behaviors consistent with select WCRF/AICR recommendations were associated with a decreased risk of developing any cancer and colorectal cancer among this Ontario cohort.

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.
