Abstract

fetched live from OpenAlex

Introducción: el objetivo fue diseñar un estudio comunitario randomizado controlado multi-componente y evaluar su efecto en la prevención de obesidad en escolares del departamento de Caaguazú, Paraguay.Material y métodos: Diseño: ensayo comunitario randomizado controlado. Lugar: 16 escuelas públicas y privadas del área urbana y rural del Departamento de Caaguazú, Paraguay. Participantes e intervención: 16 escuelas serán asignadas aleatoriamente a dos grupos. Grupo intervención, recibirán un programa de educación nutricional y actividad física en el entorno escolar durante 6 meses. Grupo control, recibirán 3 charlas educativas en el mismo periodo. Medición de las principales variables: primaria (espesor de pliegues cutáneos), secundarias (z índice de masa corporal, conocimientos nutricionales, consumo de frutas y verduras, nivel de actividad física) y variables demográficas (sexo, edad, zona de residencia). Todas las variables serán medidas en la línea base y al final del estudio, utilizando herramientas calibradas, cuestionarios validados y protocolos de procedimiento. Análisis: se utilizará estadística descriptiva, además de los test t Student y chi2 para establecer diferencias. Se correrán modelos de regresión lineal y logística crudos y ajustados.Ética y diseminación: el protocolo de estudio ha sido evaluado y aprobado por el Comité de Ética en Investigación de la Universidad Nacional de Caaguazú. Se utilizarán consentimientos informados institucionales (escuelas) e individuales (padres) y asentimiento de los niños.

Not 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.
