Consumo percibido y uso de drogas lícitas e ilícitas en estudiantes universitarios en la Ciudad de Medellín, Colombia
Bibliographic record
Abstract
El propósito de este estudio fue estimar la diferencia entre el consumo percibido en los pares y el uso real de drogas que tienen los estudiantes universitarios de segundo y tercer año, entre 18 y 24 años de edad, de una universidad pública en la ciudad de Medellín, Colombia. Se trata de un estudio descriptivo transversal basado en una encuesta. Todos los estudiantes de segundo y tercer año de las facultades de Medicina, Odontología, Enfermería y Salud Publica fueron invitados a responder un cuestionario anónimo. Participaron 427 estudiantes. Se encontró una sobreestimacion del consumo de tabaco, marihuana y cocaina en los ultimos doce meses. El consumo de alcohol es percibido de manera exacta. Los estudiantes que consumieron drogas, en el periodo mencionado, sobreestiman más que los que no lo hicieron; también se encontró que las mujeres sobreestiman más que los hombres el consumo de marihuana.

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.
