A large US trial demonstrates that integrating family-based behavioural support into standard obesity care leads to greater weight loss and improved quality of life in children, highlighting the potential for routine implementation amid access barriers.
A large US trial has found that adding family-based behavioural treatment to enhanced standard obesity care helped children with obesity lose more weight than usual primary-care management alone, strengthening the case for bringing structured family support into routine paediatric practice. The study, published in JAMA Pediatrics, followed 730 children aged six to 15 and found that almost half of those offered the combined approach achieved clinically meaningful weight loss. Researchers said the results suggest the model can work across a broad mix of families in everyday primary care.
The TEAM UP trial was led by Amanda E. Staiano of the Pennington Biomedical Research Center in Baton Rouge, Louisiana, and took place from 2019 to 2024 across 41 primary care practices in Louisiana, New York, Missouri and Illinois. Children were referred by clinicians or enrolled with a participating parent, then randomised to receive enhanced standard of care alone or the same care plus family-based behavioural treatment for 12 months, with follow-up continuing to 18 months.
The behavioural programme used trained interventionists to work with families on healthier eating, more physical activity, positive parenting and changes to the home environment that shape daily habits. The study population was notably diverse: the average age was 10.8 years, more than half the children were girls, nearly half were covered by Medicaid and more than one in five lived with food insecurity. Across the trial, both groups improved, but the reductions in median percentage BMI were greater in the children who received the additional family-based support.
Quality of life also improved in both groups, including measures linked to weight, though gains were larger in the combined-treatment arm. No trial-related adverse events were reported. The researchers said the pandemic disrupted recruitment and delivery, and they flagged lower attendance among African American families, Medicaid recipients and food-insecure households as evidence that access barriers remain. They argued that more flexible models, including telehealth, may be needed if such programmes are to reach the families who could benefit most.
The findings build on earlier work showing that family-based treatment can be delivered in primary care and can improve outcomes for children and parents alike. Previous US trials and implementation studies have also supported the feasibility of embedding this kind of intervention into routine care, while research in the UK National Health Service has suggested the approach can be acceptable and effective in ethnically and socially diverse settings. Taken together, the evidence points to family-based treatment as a practical adjunct to standard obesity care rather than a specialist-only intervention.
