155: Impact of the Pediatric Residents' Initiative for Healthy Active Living in Youth (RHALY): A Prospective Cohort Study
Bibliographic record
Abstract
Suboptimal lifestyle habits may lead to childhood overweight and obesity. Promotion of healthy active living (HAL) is an important part of clinical practice. To promote healthy lifestyle in youth, we created a resident-led HAL educational program (including a HAL counselling intervention) at the Montreal Children's Hospital. To determine the prevalence of optimal health habits in children followed in our Pediatric Residents Continuity Clinic (RCC); To examine the effect of our HAL counselling intervention on the health habits of these children. This prospective cohort included five to 16 year-old children. Our HAL educational program included 1) didactic teaching sessions on childhood obesity screening and management incorporated within the residents teaching curriculum; and 2) creation of HAL counselling tools (brochures, pamphlets, and healthy habits prescription). Pediatric residents implemented the HAL counseling intervention to patients/families using the 5,2,1,0 guidelines (four daily goals: five portions of fruits/vegetables; <2 h screen time; >1 hr physical activity, zero sugar-sweetened beverages); and HAL counselling tools. Recruited patients and families completed a questionnaire reporting their health habits at baseline, six months and one year following the intervention. We recruited 81 patients (9.3±3.1 years old; 48% females). 20% of our cohort was overweight or obese. 19% reported optimal healthy habits (i.e., met all four goals). There was an increase in the proportion of children who met three or four goals following our intervention (49% vs 64% at follow-up), P=0.035. Among overweight/obese children, the improvement was from 33% at baseline to 56% at 12 months follow-up; in non-obese children, 51% to 63%. Specifically, changes for each met goal by category from baseline compared to 12 months were: five portions of fruits/vegetables, 32% vs 49%; <2 h screen time, 58% vs 69%; >1 h physical activity, 48% vs 67%; no sugar-sweetened beverages, 44% vs 58% (P value for each goal was non-significant) The mean activity level increased by 18 min/day (75.5±53.2 vs 93.6±65.2 at follow-up), and sleep duration increased by 25 min (10.0±1.4 h vs 10.4±1.2 h), but neither reached statistical significance (P=0.074 and 0.060, respectively). We were able to show for the first time that using a HAL counselling tool in a primary clinical care setting led to a significant increase in the proportion of children meeting 5,2,1,0 guidelines after the intervention, as well as clinically important increases in physical activity level and sleep duration. Future studies are needed to validate our findings.

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.
