Abstract
W would have thought that toddlers and preschoolers would be the focus of a physical activity campaign? Children are natural movers and never seem to sit still. Do they really need our help to be active? The answer is yes. Unfortunately, more children are obese then ever before, and we need to pay attention to even very young children’s physical activity levels. Results of a study in Scotland showed that children aged 3 to 5 were getting only one third the recommended amount of physical activity each day.1 In the 15 years ending in 1996, the prevalence of overweight children in Canada increased from 15% to 20% while the prevalence of childhood obesity more than doubled.2 Adolescents are presenting with type 2 diabetes, once thought to affect only adults.3 Physical inactivity, television watching, and video game playing are risk factors for obesity in Canadian children.4 Primary care physicians, given their central role in health promotion, can increase patients’ awareness of the benefits of physical activity and help them become more active. Physicians see most preschool children for yearly checkups. Parents and guardians of preschool children need to understand the importance of children making healthy, active choices very young. The College of Family Physicians of Canada collaborated with the Canadian Paediatric Society to produce a poster (included in the polybag with this issue) specifically designed for family physicians’ and pediatricians’ waiting rooms. The poster encourages parents and guardians to ask doctors how they can promote physical activity to their preschool children. Place this poster prominently in your office and ask parents what their children are doing at play time. Encourage parents to invite their children to move throughout the house with them instead of leaving the little ones in one room, such as the family room with the television on. Parents can play follow-the-leader and hide-and-seek with their children indoors or outdoors. Dancing to music is a great activity for parents and children. Remind parents that even very young children notice when their parents are physically active. Active parent role models can make physical activity appealing to small children. We do not need to design toddler exercise training programs to fight childhood obesity. We need only help children be the naturally active little people they were meant to be.

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.
