Abstract Objective The American Academy of Pediatrics recommends that pediatric practices help families make lifestyle changes to improve BMI, but provider time and access to treatment are limited. This study compared the effectiveness of two pediatric practice‐based referral interventions in reducing BMI. Methods In this cluster‐randomized clinical trial, 20 pediatric primary care practices were randomized to telephonic coaching (Fitline Coaching) or mailed workbook (Fitline Workbook). Parents and their 8‐ to 12‐year‐old children with BMI ≥ 85th percentile completed assessments at baseline and at 6 and 12 months post baseline. Primary outcomes were 12‐month BMI percentile and z score. Results A total of 501 children and their parents received Fitline Coaching ( n = 243) or Fitline Workbook ( n = 258); 26.8% had overweight, 55.4% had obesity, and 17.8% had severe obesity. Mean (SD) age was 10.5 (1.4), and 47.5% were female. BMI percentile improved in both groups; 12‐month decline in continuous BMI z score was not statistically significant in either group. However, 20.8% of telephonic coaching participants and 12.4% of workbook participants achieved a clinically significant reduction of at least 0.25 in BMI z score, a significant between‐group difference ( p = 0.0415). Conclusions 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.
