A pediatric primary care practice‐based obesity intervention to support families: a cluster‐randomized clinical trial
Authors' conclusion
Both low-intensity interventions were acceptable and produced modest improvements in BMI percentile. One in five children in the telephonic coaching condition achieved clinically meaningful BMI z score improvements. However, more research is needed before such a program could be recommended for pediatric primary care practice.
Study context

- Parents and their 8- to 12-year-old children with BMI ≥ 85th percentile, 20 pediatric primary care practices; 26.8% overweight, 55.4% obesity, 17.8% severe obesity; mean (SD) age 10.5 (1.4), 47.5% femalechildren and their parents
- Participants
- 501 parents

Primary result
As reported in the abstract
- BMI percentile improved in both groups
- 12-month decline in continuous BMI z score not statistically significant in either group
Further findings
Clinically significant reduction of ≥0.25 in BMI z score · significant between-group difference
