Researchers hope to recruit 1,250 families in Waukesha County, starting next year, who are willing to allow scientists to study their children through medical tests and physical examinations for more than 20 years. Participants might be compensated or offered other incentives.
Other pilot sites are in California, New York, Pennsylvania, Utah, North Carolina and South Dakota.
Coordinated locally by the Medical College of Wisconsin and the University of Wisconsin-Madison, the $2.7 billion study is being funded by the federal government.
