Johns Hopkins National Children's Study Center

The National Children's Study is the largest study to be conducted on the effects of enviromental and genetic factors on child and human health in the United States. The study will follow a representative nationwide sample of 100,000 children from before birth to age 21, seeking information to prevent and treat some of the nation's most pressing health problems, including autism, birth defects, diabetes, heart disease, and obesity.

In Maryland, Baltimore County and Montgomery County were selected as potential National Children's Study locations. A Study Center has been established at Johns Hopkins University under the direction of pediatrician Lynn Goldman, MD, MPH. Baltimore County is part of "Wave 1" for the  study and Montgomery County is part of "Wave 2".

The Johns Hopkins Bloomberg School of Public Health has been selected as a study center in the National Children’s Study to assess the effects of environmental and genetic factors on child and human health in the United States. The study center manages local participant recruitment and data collection in the largest study of child and human health ever conducted in the United States.

Working with the local health department, neighborhood and community organizations, hospitals and parents groups, the Johns Hopkins National Children's Study Center will recruit and enroll 1,000 women from neighborhoods in Baltimore County to participate in this long term effort to examine a host of health outcomes, including pregnancy, neurodevelopment and behavior, child health and development, asthma and growth, injury and reproductive development. The study will also look at childhood chronic conditions as they are influenced by environmental factors such as chemical exposures, the physical environment, the psychosocial environment, as well as by biological and genetic factors.

The National Children’s Study eventually will follow a representative sample of 100,000 children from before birth to age 21, seeking information to prevent and treat some of the nation’s most pressing health problems, including autism, birth defects, diabetes, heart disease, and obesity.

In total, the study will be conducted in 105 previously designated study locations across the United States that together are representative of the entire U.S. population. A national probability sample was used to select the counties in the study, which took into account factors including race and ethnicity, income, education level, number of births and number of babies born with low birth weights.

"What we learn will help promote the well-being of children and families in Baltimore County, Maryland, and across the Unites States and shape child health guidance, interventions, and policy for generations to come," said Lynn Goldman, MD, MPH principle investigator of the new center and a professor in the Bloomberg School of Public Health’s Department of Environmental Health Sciences. "Only a study of the magnitude of the National Children’s Study can provide answers to some of the most important questions about how we help children meet their full potential for health and development."

The Bloomberg School of Public Health is one of 36 new study centers of the National Children’s Study, a collaborative effort between the U.S. Department of Health and Human Services—including the National Institute of Child Health and Human Development (NICHD) and the National Institute of Environmental Health Sciences at the National Institutes of Health (NIH) and the Centers for Disease Control and Prevention—and the U.S. Environmental Protection Agency.
