Michigan is getting $57 million from the National Institutes of Health to expand its role in a research project to study children's health.

The National Children's Study aims to learn how the environment and other factors affect youngsters' health, especially development of such conditions as autism, asthma, learning disabilities, diabetes and obesity.

Participants in the state include Michigan State University, the University of Michigan, Wayne State University, Children's Hospital of Michigan, Henry Ford Health System and the Michigan Department of Community Health.

The funding announced Friday is for the study of children in Genesee, Grand Traverse, Lenawee and Macomb counties. That funding is in addition to $18.5 million announced for work in Wayne County.
