This article reports on an innovative lead screening program for young children, designed and implemented by members of the Chippewa and Cree tribes on the Rocky Boy Reservation near Box Elder, Montana. Since most children living on the reservation participate in WIC and Head Start, the tribes were able to identify and screen close to 100 percent of young children living on the reservation. Screening results indicate that the average blood lead level for children age 15 was not significantly different from that of children of the same age nationally. The initiative also showed that Indian families participate readily in programs that may improve their children's health. Funding for the study was provided by the Environmental Protection Agency (Public Health Reports 119, March/April 2004).
