The association of cannabis use with fast-food consumption, overweight, and obesity among adolescents aged 12-15 years from 28 countries
Bibliographic record
Abstract
Background \nCannabis legalization and use have risen globally. However, the association between cannabis use, eating behaviors and body weight among adolescents is yet unexplored. \nObjectives \nThis study examined the association between cannabis use, fast-food consumption, overweight and obesity in 28 countries using data from the 2010–2016 Global School-Based Student Health Survey. \nMethods \nMultivariable logistic regression and meta-analysis were performed among a sample of 83,726 adolescents (48.7% females) aged 12–15 years, mean (SD) age of 13.8 (0.9) years. \nResults \nThe overall prevalence of cannabis use (in past 30 days) and fast-food consumption (in past 7 days) were 2.8% and 57.3% respectively. The overall prevalence of overweight and obesity was 14.7% and 4.2%, respectively. Cannabis use was significantly associated with fast-food consumption (OR = 1.33; 95%CI = 1.13–1.57) but not with overweight (OR = 0.95; 95%CI = 0.80–1.14) or obesity (OR = 1.16; 95%CI = 0.85–1.59). For obesity, there was a moderate level of between-country heterogeneity (I2 = 51.9%) and significant positive associations with cannabis use were observed in Bahamas, Bangladesh, Namibia and Nepal. \nConclusion \nThe results highlight the association between cannabis use and dietary risks, providing evidence for public health interventions on the interrelated nature of cannabis use and fast-food consumption.

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.
