Abstract
OBJECTIVES: Low back pain (LBP) is frequent and burdensome among police officers, but occupational and ergonomic factors associated with LBP and its chronic symptoms have never been studied among these workers using a biopsychosocial model. This study aimed at exploring such factors associated with acute or subacute LBP and chronic low back pain (CLBP) among car-patrol police officers. METHODS: A web-based cross-sectional study was conducted among car-patrol officers working in the province of Quebec (Canada). Factors associated with acute or subacute LBP and CLBP (as opposed to absence of LBP) were studied using a multivariate multinomial regression model. RESULTS: A total of 2208 car-patrol officers composed the study population. Statistically significant occupational/ergonomic determinant for higher prevalence of acute or subacute LBP was more frequent discomfort in the lower back when sitting in the patrol car as a driver (adjusted odds ratio [OR], 3.008; 95% confidence interval [CI], 2.170-4.168). More frequent posttraumatic interventions was associated with lower prevalence of acute or subacute LBP (adjusted OR, 0.609; 95% CI, 0.410-0.907). Occupational and ergonomic factors associated with higher prevalence of CLBP were greater seniority (adjusted OR, 1.061; 95% CI, 1.007-1.118) and more frequent discomfort in the lower back when sitting in the patrol car as a driver (adjusted OR, 7.546; 95% CI, 5.257-10.831). DISCUSSION: Few occupational and ergonomic factors that police organizations could use to better tailor prevention were found to be associated with acute or subacute LBP and CLBP. This cross-sectional study is an efficient first investigation for screening hypotheses that should be confirmed in further cohort studies.

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
