TLC-HEAT: Telephony-based self-care for overweight children.

Efforts to use information technology (IT) to link pediatric primary care patients in the home with their clinicians have been rudimentary to date. We have developed a model information system that uses a ubiquitous user-interface, the telephone, and the electronic health record (EHR) to support health behavior change and weight loss for overweight urban children and their parents. In this paper, we present the technical architecture and underlying psychological theories used to build the system.
