The NICHD Office of the Director has primary responsibility for planning and coordinating the National Children's Study, the largest and longest study of environmental effects on children’s health ever conducted in the United States.
The Study will follow 100,000 children from before birth to age 21 to examine the effects of environmental influences on their health and development. The National Children's Study will be the first effort to capture environmental exposures prior to and early in pregnancy, and then to track so many participants for more than 20 years. The ability to examine multiple environmental exposures and link them in a cause-effect relationship with multiple outcomes is the defining characteristic of the Study.
