Authorized by Congress as part of the Children’s Health Act of 2000, the National Children’s Study (NCS) is a nationwide longitudinal study of 100,000 children from before birth to 21 years of age. Study/coordinating centers across the country are recruiting expectant mothers to enroll their children, answer periodic survey questions, and donate specimens during their developmental years.
The goal of the NCS is to investigate and identify the environmental-genetic interactions and risk factors for birth defects, pre-natal problems, obesity, asthma, cancer, and other disorders. Throughout the course of the study, biological samples (urine, blood, breast milk, saliva, hair, and nail clippings, among others) will be collected from the child and/or mother; environmental samples (dust, water, soil) will also be collected from the child’s home surroundings, in conjunction with periodic physical, cognitive, and behavioral assessments.
