 Specific aims of this project are: 1 to establish a primary care based and parent-mediated childhood overweight intervention program based on the Chronic Care Model in the primary care setting, 2 to explore the efficacy of this intervention in improving the weight status of children, 3 to examine the acceptability and feasibility of the approach among primary care providers and parents. Clinic providers and study personnel will be trained in the use of brief motivational interviewing brief MI for the visits and phone calls. The American Academy of Pediatrics 15-Minute Obesity Prevention Protocol will be used for individual visits while the NIH We Can! curriculum and materials will be used for group visits. Parents in the control group will receive the We Can! Parent Handbook and usual care. The intervention is designed to facilitate efficient communication of advice about behavior change, nutrition, and physical activity to parents. Partnership of primary care providers with parents and use of brief intervention techniques and group visits can be a practical approach. If proven to be effective, this approach can serve as an exportable model to other primary care practices and will reach a large proportion of the population and have far-reaching effects.
