The total impact of a health promotion program can be measured by the efficacy of the intervention multiplied by the extent of its implementation across the target population. The Child and Adolescent Trial for Cardiovascular Health (CATCH) was a school-based health promotion project designed to decrease fat, saturated fat, and sodium in children's diets, increase physical activity, and prevent tobacco use. This article describes the dissemination of CATCH in Texas, including the theoretical framework, strategies used, and lessons learned. To date (Fall 2000), CATCH materials have been adopted by more than 728 elementary schools in Texas.
