Early‐Onset Obesity and Tirzepatide Treatment: A Post Hoc Analysis of the <scp>SURMOUNT</scp> Clinical Trials
Bibliographic record
Abstract
OBJECTIVE: People with early-onset obesity (diagnosed at age < 25 years) may present with more cardiometabolic abnormalities and obesity-related complications. This post hoc analysis assessed baseline characteristics and body weight (BW) changes with tirzepatide in people with early- versus later-onset obesity. METHODS: Participants (N = 3782) from SURMOUNT-1, SURMOUNT-3, and SURMOUNT-4 randomized to tirzepatide or placebo were included. Baseline characteristics and changes in BW and cardiometabolic risk factors at 72/88 weeks were assessed. RESULTS: ) and waist circumference (WC, 118 ± 16 vs. 112 ± 14 cm), and lower HbA1c (5.48% ± 0.4% vs. 5.60% ± 0.4%), triglycerides (median 120 vs. 130 mg/dL), and systolic blood pressure (SBP; 121 ± 13 vs. 125 ± 13 mmHg) at baseline (all p ≤ 0.004). At 72 weeks, improvements with tirzepatide in BW (-23% vs. -22%), WC (-22 vs. -19 cm), HbA1c (-0.51% vs. -0.52%), triglycerides (-32% vs. -31%), and SBP (-8 vs. -8 mmHg) were similar between subgroups. Similar improvements were observed in SURMOUNT-3 and SURMOUNT-4. CONCLUSIONS: In this post hoc analysis, participants with early- versus later-onset obesity exhibited a mixed profile of metabolic health at baseline, including a higher degree of central adiposity and lower HbA1c and SBP. Improvements in BW and cardiometabolic markers with tirzepatide were similar between subgroups. TRIAL REGISTRATION: ClinicalTrials.gov identifiers: NCT04184622, NCT04657016, NCT04660643.

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.
