Tobacco use among school enrolled and no enrolled adolescent in Medellin, Colombia. A population survey
Bibliographic record
Abstract
Background:Tobacco use among adolescents is a problematic risk behavior with early age of onset and consequences in health outcomes in adulthood. Objectives: Estimate the prevalence of tobacco use among adolescents at school and off school. Methods: A community-base cross sectional study was conducted during 2007 to estimate the prevalence of tobacco consumption in adolescents aged 12-15 (n=1.998), school and off school. A multistage probability sampling was conducted. Results: Life prevalence of tobacco consumption was 26.8% and currently use tobacco was 6%, the age onset was 11 years; non-enrolled in school adolescents had higher smoking rates. Majority of current smokers were able to buy cigarettes. Conclusion: Non-enrolled adolescents have more risk to tobacco use. Public policies should generate strategies to intervene this population. It is important to conduct the Global Youth Tobacco Survey in a national sample of adolescents including of school adolescents and establish an epidemiological surveillance system of risk behaviors based on surveys conducted periodically.Antecedentes:El consumo de tabaco entre los adolescentes es un comportamiento de riesgo problemática para la salud, de inicio cada vez mas temprano y afecta los resultados de salud. Objetivo: Estimar la prevalencia de consumo de tabaco entre los adolescentes escolarizados y no escolarizados. Métodos: Estudio transversal de base poblacional en 2007 para estimar la prevalencia de consumo de tabaco en adolescentes de 12-15 (n = 1.998), escolarizado y no escolarizados. Se uso muestreo probabilístico pilietápico. Resultados: La prevalencia en vida de consumo de tabaco fue del 26,8% y el consumo actual de tabaco fue del 6%, la aparición de edad fue de 11 años; no inscrito en adolescentes escolares tenían mayores tasas de tabaquismo. La mayoría de los fumadores actuales fueron capaces de comprar cigarrillos. Conclusión: los adolescentes no escolarizados tuvieron más riesgo para el consumo de tabaco. Las políticas públicas deben intervenir la población no-escolarizadas. Es importante llevar a cabo la Encuesta Mundial de Tabaquismo en Jóvenes en una muestra nacional que incluya adolescentes incluyendo escolarizados y no escolarizados y establecer un sistema de vigilancia epidemiológica de las conductas de riesgo en base a encuestas realizadas periódicamente.

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.
