National Children's Study Seeks to Explain Native American Child Health Disparities

On December 12, 2014, the NIH Director decided to close the National Children’s Study. The information on this page is not being updated and is provided for reference only.

The U.S. Census Bureau reports that there are approximately 2.5 million American Indians in the United States, constituting 0.9 percent of the total population, and that they live primarily in the West, Southwest, and Midwest.

Native American children today suffer disproportionately from diabetes, injuries, and other health problems. The planned National Children's Study ( would be the largest research study of the environment's effects on children's health and development ever conducted in the United States. It would follow 100,000 children from before birth to age 21. The study would include Native American children in accordance with their proportion of the population.

The Health of Native American Children

Geographic isolation, economic conditions, and inadequate sewage disposal are among the factors that contribute to poorer health outcomes among the nation's American Indians and Alaska Natives ( In addition, Native American children bear a disproportionate burden of many health problems. For example:

Through the planned National Children's Study, researchers hope to uncover the root causes of health disparities that would ultimately reduce the health disparities experienced by all groups. Study findings would help Native American communities "and indeed all communities" prevent health problems and keep families healthy, and might even lead to new treatments and cures for diseases.


The NICHD is part of the National Institutes of Health (NIH), the biomedical research arm of the federal government. NIH is an agency of the U.S. Department of Health and Human Services. The NICHD sponsors research on development, before and after birth; maternal, child, and family health; reproductive biology and population issues; and medical rehabilitation.
