Insights
Children in a multidisciplinary weight management program showed greater body mass index (BMI) reductions than those in usual care. Younger children (<5 years) experienced the best outcomes in this pediatric weight management study.
Area of Science:
- Pediatrics
- Obesity Management
- Public Health
Background:
- Childhood obesity is a significant public health concern requiring effective management strategies.
- Multidisciplinary programs offer a comprehensive approach to pediatric weight management.
- Understanding the comparative effectiveness of such programs versus usual care is crucial.
Purpose of the Study:
- To compare body mass index (BMI) changes in children participating in a multidisciplinary weight management program versus those receiving usual primary care.
- To analyze BMI z-score trajectories over a 2-year period in referred overweight or obese children.
- To identify factors influencing treatment outcomes, such as age.
Main Methods:
- Retrospective database analysis of 583 overweight or obese children referred to a pediatric weight management program.
- Utilized multivariable mixed-effect models to compare 2-year BMI z-score trajectories.
- Compared outcomes between program participants (n=338) and nonparticipants (n=245) followed by primary care providers.
Main Results:
- Program participants demonstrated a modest decrease in mean BMI z-score over 2 years, which was lower than nonparticipants.
- Statistically significant differences in the rate of BMI z-score change were observed between groups at 0-6 months and 19-24 months post-referral.
- Younger participants (under 5 years) showed significantly better outcomes across all examined time points.
Conclusions:
- Pediatric multidisciplinary weight management programs lead to greater BMI z-score reductions compared to usual primary care in a real-world setting.
- Early intervention, particularly in younger children, appears to yield superior outcomes in pediatric weight management.
- Further research into the cost-effectiveness of these programs is warranted.
Abstract:
Objective. To examine body mass index (BMI) changes among pediatric multidisciplinary weight management participants and nonparticipants. Design. In this retrospective database analysis, we used multivariable mixed effect models to compare 2-year BMI z-score trajectories among 583 eligible overweight or obese children referred to the One Step Ahead program at the Boston Children's Primary Care Center between 2003 and 2009. Results. Of the referred children, 338 (58%) attended the program; 245 (42%) did not participate and were instead followed by their primary care providers within the group practice. The mean BMI z-score of program participants decreased modestly over a 2-year period and was lower than that of nonparticipants. The group-level difference in the rate of change in BMI z-score between participants and nonparticipants was statistically significant for 0-6 months (P = 0.001) and 19-24 months (P = 0.008); it was marginally significant for 13-18 months (P = 0.051) after referral. Younger participants (<5 years) had better outcomes across all time periods examined. Conclusion. Children attending a multidisciplinary program experienced greater BMI z-score reductions compared with usual primary care in a real world practice; younger participants had significantly better outcomes. Future research should consider early intervention and cost-effectiveness analyses.
