UC Davis Health System has been selected as a new site for the National Children's Study, which is assessing the effects of environmental and genetic factors on 100,000 children from before birth to age 21 in the United States. The new center will manage community engagement, local recruitment and data collection on 2,000 children in Sacramento and San Mateo counties. UC Davis will receive nearly $31.8 million over seven years for its portion of the study, being led by epidemiologist Irva Hertz- Picciotto. The National Children's Study is funded by the U.S. Department of Health and Human Services and the U.S. Environmental Protection Agency.
