PHYSICAL ACTIVITY AND PSYCHOSOCIAL OUTCOMES IN OBESE CHILDREN
Bibliographic record
Abstract
The effects of obesity on psychosocial health in children has been relatively understudied and poorly characterized. Further, most evaluations have considered obese children as a homogeneous group thereby ignoring potential within-group differences based on lifestyle behaviors and attitudes. PURPOSE The purpose of the present study was to assess psychosocial health in a sample of 83 (48 boys, 35 girls; 88% Caucasian) 6 – 12 year old obese youth classified as either low physical activity (LPA) or high physical activity (HPA). METHODS Upon the completion of a 7-day physical activity recall questionnaire, scores were rank ordered. Children scoring below or above the median were categorized as LPA or HPA, respectively. In addition, participants completed the Self-Perception Profile for Children, the Children's Physical Self-Concept Scale, and body image dissatisfaction questionnaires. All boys and girls also had the following assessments done: height, weight, sum of 5 skinfolds, body composition (fat mass, lean mass, and percent body fat by dual-energy X-ray absorptiometry) and aerobic fitness (peak VO2 using a cycle ergometer). RESULTS Group comparisons of demographic (ethnicity and age), anthropometric, body composition, and aerobic fitness variables revealed no significant differences. However, after adjusting for gender and Tanner stage, children in the HPA group exhibited more positive ratings of social acceptance (p = 0.004), physical performance (p < 0.001), physical appearance (p = 0.046), and global physical self-perception (p = 0.002) compared to the LPA group. CONCLUSION These findings suggest that obese children who possess relatively high levels of physical activity exhibit a more favorable psychosocial health profile than obese children who are less physically active. Additionally, these data support the concept that obese children are not a homogeneous population and that a physically active lifestyle is related to a healthier self-concept within a sub-set of obese boys and girls.

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.
