Insights
A shared-care model for childhood obesity management, involving pediatric specialists and general practitioners, may improve treatment accessibility. This approach aims to enhance care for overweight and obese children, addressing a critical public health need.
Area of Science:
- Pediatric Endocrinology
- Public Health
- General Practice
Background:
- Childhood obesity rates are increasing, yet effective, accessible treatments are scarce.
- Current tertiary specialist services reach only a limited number of children.
- General practitioner (GP) care alone has shown insufficient improvement in body mass index (BMI) trajectories for obese children.
Purpose of the Study:
- To evaluate the efficacy of a shared-care model for managing childhood obesity.
- To determine if pediatric obesity specialists co-managing with GPs can improve adiposity in obese children.
- To assess the feasibility of a GP-based, shared-care model for broader access to obesity management.
Main Methods:
- A randomized controlled trial nested within a BMI survey across 22 Australian general practices.
- Participants: Obese children aged 3-10 years (CDC criteria).
- Intervention: A single specialist multidisciplinary clinic appointment followed by 12 months of GP co-management, supported by web-based shared-care software.
Main Results:
- Primary outcome: Change in BMI z-score.
- Secondary outcomes: Changes in body fat percentage, waist circumference, health status, body satisfaction, and self-worth.
Conclusions:
- This study represents the first efficacy trial of a GP-based, shared-care model for childhood obesity.
- A successful shared-care model could significantly enhance access to effective obesity management for children.
- The findings aim to inform scalable interventions for the growing childhood obesity epidemic.
Background:
Despite record rates of childhood obesity, effective evidence-based treatments remain elusive. While prolonged tertiary specialist clinical input has some individual impact, these services are only available to very few children. Effective treatments that are easily accessible for all overweight and obese children in the community are urgently required. General practitioners are logical care providers for obese children but high-quality trials indicate that, even with substantial training and support, general practitioner care alone will not suffice to improve body mass index (BMI) trajectories. HopSCOTCH (the Shared Care Obesity Trial in Children) will determine whether a shared-care model, in which paediatric obesity specialists co-manage obesity with general practitioners, can improve adiposity in obese children.
Design:
Randomised controlled trial nested within a cross-sectional BMI survey conducted across 22 general practices in Melbourne, Australia.
Participants:
Children aged 3-10 years identified as obese by Centers for Disease Control criteria at their family practice, and randomised to either a shared-care intervention or usual care.
Intervention:
A single multidisciplinary obesity clinic appointment at Melbourne's Royal Children's Hospital, followed by regular appointments with the child's general practitioner over a 12 month period. To support both specialist and general practice consultations, web-based shared-care software was developed to record assessment, set goals and actions, provide information to caregivers, facilitate communication between the two professional groups, and jointly track progress.
Outcomes:
Primary - change in BMI z-score. Secondary - change in percentage fat and waist circumference; health status, body satisfaction and global self-worth.
Discussion:
This will be the first efficacy trial of a general-practitioner based, shared-care model of childhood obesity management. If effective, it could greatly improve access to care for obese children.
