Summary Objectives This study will test the efficacy of motivational interviewing ( MI ) conducted by primary care providers and dieticians among children ages 2‐8 years old with a body mass index ( BMI ) ≥85th and ≤97th percentile. Methods Forty‐two practices from the A merican A cademy of P ediatrics, P ediatric R esearch in O ffice S ettings N etwork were assigned to one of three groups. Group 1 (usual care) measures BMI percentile at baseline, and at 1‐ and 2‐year follow‐ups and receives standard health education materials. Group 2 providers deliver three proactive MI counselling sessions with a parent of the index child in Y ear 1 and one additional ‘booster’ visit in Y ear 2. Group 3 adds six MI counselling sessions from a trained dietician. The primary outcome is the child's BMI percentile at 2‐year follow‐up. Secondary outcomes include parent report of the child's screen time, physical activity, intake of fruits and vegetables, and sugar‐sweetened beverages. Results We enrolled 633 eligible children whose mean BMI percentile was 92.0 and mean age of 5.1. The cohort was 57% female. Almost 70% of parents reported a household income of ≥$40 000 per year, and 39% had at least a college education. The cohort was 63% W hite, 23% H ispanic, 7% B lack and 7% A sian. Parent self‐reported confidence that their child will achieve a healthy weight was on average an 8 (out of 10). Conclusion To date, several aspects of the study can inform similar efforts including our ability to use volunteer clinicians to recruit participants and their willingness to dedicate their time, without pay, to receive training in MI .
