A cross‐sectional study of overweight in pediatric survivors of acute lymphoblastic leukemia (ALL)
Bibliographic record
Abstract
BACKGROUND: Survivors of childhood acute lymphoblastic leukemia (ALL) are at risk for overweight, predisposing them to long-term morbidity. We examined the relationship between body mass index (BMI) and demographic and lifestyle factors in a cohort of ALL survivors. PROCEDURE: We enrolled consecutive ALL survivors who attended the institutional AfterCare Clinic over a 1-year period. BMI (kg/m(2) ) at diagnosis, end-therapy, and current time were calculated. Survivors were classified as overweight/obese (overweight group; BMI for age ≥ 85th percentile) or normal/underweight (normal weight group; BMI for age <85th percentile). We assessed the relationship between current BMI and self-reported current caloric intake, physical activity, and sedentary behavior. RESULTS: 102/157 (65%) eligible survivors consented to enrollment. Median age was 14.3 years (range 8.4-18.6) and time from end of treatment 7 years (2.5-15.6). The proportion of overweight survivors was 21%, 45%, and 35% at diagnosis, end-therapy, and current time, respectively. The overweight group reported less calories (Δ324 kcal, P = 0.018), fat (Δ14.5 g, P = 0.02), and carbohydrates (Δ39 g, P = 0.02) than the normal weight group. These differences disappeared after excluding patients classified as under-reporting their calorie intake according to the Goldberg cut-off method. There were no differences in sedentary behavior or activity between groups. CONCLUSIONS: Many children with ALL gain weight during therapy and fail to return to normal weight after treatment concludes. Subsequent diet, physical activity, and sedentary behavior do not appear to differ between overweight and normal weight survivors. Clinicians should focus on ways to minimize weight gain during therapy rather than waiting for treatment to conclude.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
