Abstract
1272 The First Step Program (FSP) is a pedometer-based physical activity intervention that was developed using a systematic process that included a needs assessment and consultation with program deliverers and recipients. Formative evaluation was used to refine program elements and establish feasibility and acceptability. A preliminary outcome evaluation established expected magnitudes and patterns of physical activity behavior change and was used to obtain funding for a randomized controlled trial (RCT) of 47 overweight/obese, sedentary individuals (age = 52.7 ± 5.2 years; BMI = 33.3 ± 5.6 kg/m2). Relative to the control group, FSP participants increased their physical activity > 3000 steps/day (approximately 30 minutes/day) during the intervention (P < 0.0001). Associated changes in health-related outcomes were modest. As part of planning for dissemination, effectiveness of program delivery under real world conditions was evaluated through diabetes education centers across Canada. Eleven trained Diabetes Educators (DE) delivered the FSP to 125 individuals with type 2 diabetes (age = 55 ± 7 years; BMI = 35.7 ± 7.3 kg/m2) and elicited similar significant outcomes to the RCT. Finally, outcomes elicited through FSP programs delivered by peer leaders (i.e. FSP graduates) to 65 individuals with type 2 diabetes (age−57.5 ± 7.5 years; BMI = 40.3 ± 27.8 kg/m2) were compared and found not be significantly different from matched DE-led programs, and were also consistent with results from the RCT. The FSP has also been successfully adapted to non-diabetic populations, specifically to 104 individuals in sedentary workplaces. Six DE and six peer leaders have now been trained as Master Trainers, charged with additional training local FSP facilitators. The evaluation of this latest phase of dissemination is on-going. From research to practice, the FSP consistently elicits substantial increases in pedometer-determined physical activity that are accompanied by modest changes in health-related outcomes. Expansion of a peer leader network would provide a practical and feasible delivery model.

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.
