Introduction to issues and implications of screening, surveillance, and reporting of children's BMI.

On January 16 and 17, 2008, the Robert Wood Johnson Foundation convened a forum of researchers and practitioners working on the issue of childhood obesity to discuss the issues related to surveillance, screening, and reporting of children’s BMI. Because obesity has become a major concern of the foundation, it seemed essential to understand the use and limitations of the BMI measurement on which the diagnosis of obesity depended. The goals of themeeting were to gather and review experience in the collection of BMI data and to understand how to communicate BMI results to parents. In addition, the group explored cultural differences in how the BMI was interpreted, and considered the legal and confidentiality implications of collecting and reporting BMI data.
