Physical multimorbidity and quit outcomes in a publicly funded smoking cessation programme
Bibliographic record
Abstract
OBJECTIVES: To examine the association between physical multimorbidity and 6-month quit outcomes among treatment-seeking smokers. METHODS: We analysed data from 120 732 adults enrolled in Ontario's largest publicly funded smoking cessation programme. At enrolment, participants self-reported zero, one or two or more chronic physical health conditions. The primary outcome was 7-day point prevalence abstinence at 6 months. We used mixed-effects logistic regression to assess the association between multimorbidity and quit outcomes, adjusting for demographic and tobacco use characteristics. RESULTS: Of participants, 39.4% reported no conditions, 26.8% reported one and 33.8% reported two or more. Those with multimorbidity were older, had lower socioeconomic status and showed higher tobacco dependence but also greater motivation to quit. Compared to individuals without comorbidities, those with one condition (OR = 0.94, 95% CI: 0.90-0.98) and those with two or more (OR = 0.81, 95% CI: 0.77-0.85) had lower odds of quitting. Mental health conditions further reduced quit success among those with physical multimorbidity. DISCUSSION: Physical multimorbidity is associated with 19% lower odds of cessation success despite high motivation to quit. Tailored, intensive cessation support may improve outcomes for this high-risk group.

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.
