Objective This study aimed to examine whether 1‐month BMI improvement is predictive of superior 6‐ and 12‐month BMI changes in a national sample of youth in pediatric weight management treatment. Methods Participants were 4‐ to 18‐year‐olds from the Pediatric Obesity Weight Evaluation Registry, a prospective study collecting data from 31 pediatric weight management programs across the United States. Response at 1 month was defined as ≥ 3% BMI reduction; success at 6 and 12 months was defined as ≥ 5% BMI reduction from baseline. Analyses used linear and logistic regression with robust variance estimation. Results Primary analyses were completed with 687 participants (mean age 12.2 years). One‐month responders demonstrated significant improvements in BMI compared with nonresponders at 6 months (BMI, −2.05 vs. 0.05; %BMI, −5.81 vs. 0.23; P < 0.001 for all) and 12 months (BMI, −1.87 vs. 0.30; %BMI, −5.04 vs. 1.06; P < 0.001 for all). The odds of success for 1‐month responders were 9.64 (95% CI: 5.85‐15.87; P < 0.001) times that of nonresponders at 6 months and 5.24 (95% CI: 2.49‐11.02; P < 0.001) times that of nonresponders at 12 months. Conclusions In treatment‐seeking youth with obesity, early BMI reduction was significantly associated with greater long‐term BMI reduction. Nonresponders may benefit from early treatment redirection or intensification.
