Before and during the first half of the previous century, infectious diseases were the primary threat to children s health. In contrast, the major illnesses and disorders that impair health, growth, and development today are chronic conditions stemming from the complex interaction of environmental exposures and inherent genetic factors. The Children s Health Act of 2000 directed the National Institute of Child Health and Development to conduct a national longitudinal study of environmental influences on children s health in the United States. The act specified that the study extend from the prenatal period to adulthood and investigate the short-term and long-term influences of physical, chemical, biological, and psychosocial environmental exposures on children s health and development, including behavioral, emotional, and educational outcomes in addition to physical health. The National Children s Study (NCS) is an observational longitudinal study that will enroll and follow a nationally representative sample of approximately 100,000 U.S.-born children from before birth through their 21st birthday. The study will screen all households within selected areas of 105 locations (primarily counties).\n\nThe major types of analysis of NCS data will include longitudinal exposure-outcome analysis, identification of causal pathways, analysis of neighborhood effects, evaluation of temporal effects within longitudinal data analysis of data from case-control data, and analysis of genomic data.\n\nWomen in their first trimester of pregnancy will be invited to participate in the pre-pregnancy portion of the NCS. Women who are not pregnant but have a high probability of becoming pregnant will be asked to participate in the early pregnancy portion of the NCS. All other eligible women will be asked if the study can contact them periodically to assess their pregnancy status. They also will be asked to contact the NCS should they become pregnant. Women identified as pregnant within 4 years after initial screening will be invited to enroll in the NCS.\n\nThe following information will be gathered:\n\nMother s data and information\n\n* Questionnaire data interviewed and self-administered (e.g., demographics; current pregnancy history; reproductive history; medical conditions; health behaviors; doctor visits; medicines and supplements; housing characteristics; pesticides, product use; occupation, hobbies; depression, stress; social support; diet; time and activity)\n* Physical measures and clinical data (e.g., blood pressure, sonograms, height, weight, body measurements)\n* Biologic specimens (e.g., blood, urine, hair, saliva)\n* Environmental samples during home visits (e.g., dust, air, water)\n* Medical record abstraction\n\nInfant s data and information at birth\n\n* Cord blood and tissue samples of the placenta and umbilical cord\n* Standardized neurobehavioral exam\n* Physical measures and clinical data (e.g., length; weight; circumferences of head, arm, abdomen, thigh)\n* Meconium samples\n* Medical diagnoses and treatment by report\n* Selected Medical record abstraction', 'detailedDescription': 'The National Children s Study (NCS) is a planned, observational, and longitudinal study that will enroll and follow a national sample of approximately 100,000 children born in the United States (US) to participating women from before birth through the child s 21st birthday. The goal of the NCS is to provide information that will ultimately lead to improvements in the health, development, and well-being of children. The primary aim of the NCS is to investigate the separate and combined effects of environmental exposures (chemical, biological, physical, and psychosocial) as well as gene-environment interactions on pregnancy outcomes, child health and development, and precursors of adult disease. In-person contacts with the NCS participants include visits during pregnancy, after delivery, and throughout infancy and childhood at the participant s home and sometimes in a clinical setting. The collection of biospecimens, environmental samples, and physical measures is involved in addition to the examination of the infant and periodic contacts with the family. In addition, interim phone interviews regularly occur with in-person contacts. The NCS consists of the NCS Vanguard Study with any sub-studies and the NCS Main Study with any sub-studies. The Vanguard Study is the precursor to the Main Study.\n\nThe NCS Vanguard Study is designed and implemented to determine the feasibility, acceptability and cost of the elements that will form the Main Study. The Vanguard Study enrolls participants at forty Study locations and will have a planned duration of 21 years following completion of enrollment. The Vanguard Study will precede the Main Study on an ongoing basis to pilot all aspects of the Main Study. The specific objectives of the Vanguard Study are:\n\n1. Evaluation of recruitment, enrollment and retention strategies\n2. Evaluation of study logistics and operations including sites and mechanisms of data acquisition, collection, transport and storage of environmental and biological samples, and design and performance of information systems\n3. Evaluation of study visit assessments for feasibility, acceptability, reliability, reproducibility, cost, value, stability, and redundancy with other assessments\n\nFamilies who participate in the NCS will come from forty Study locations across the US. Study visit assessments are the tests, environmental samples, biospecimens, questionnaires and other forms of data acquisition that are scheduled at the study visits. The evaluation of the Vanguard Study will be based on a series of targeted and specific statistical techniques and tests selected for each evaluation. Multiple performance measures will be used to inform the scope, design, visit structure and schedule, mechanisms and procedures, and analysis plan for the Main Study.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': "Women of child bearing potential, their children, the children's biological and/or ocial fathers, and primary caregivers (if other than parent)", 'healthyVolunteers': False, 'eligibilityCriteria': '* IINCLUSION CRITERIA:\n* Women age 18-49 years of age at the time of enumeration who medically could be pregnant\n* Pregnant women at or above the local age of majority\n* During the Initial Vanguard Study recruitment period only: pregnant women aged younger than 18, residing in a selected NCS geographic segment at the time of enrollment, who are considered to be emancipated minors per the laws of their jurisdiction or minor pregnant women who obtain parental consent for participation\n* Children born to enrolled women\n* Biological and social fathers as identified by enrolled women\n* Adult guardians who have legal responsibility to authorize needed care for enrolled children\n* Adults who are primary caregivers of enrolled children\n\nEXCLUSION CRITERIA:\n\n* Women self-reported to be infertile\n* Adults who are unable to understand what is involved in NCS participation and grant informed consent\n* Prisoners as defined in 45 CFR 46.303\\[c\\]'}, 'identificationModule': {'nctId': 'NCT00852904', 'briefTitle': 'National Children s Health Study', 'organization': {'class': 'NIH', 'fullName': 'National Institutes of Health Clinical Center (CC)'}, 'officialTitle': 'Vanguard Phase of the National Children s Study', 'orgStudyIdInfo': {'id': '999909083'}, 'secondaryIdInfos': [{'id': '09-CH-N083'}]}, 'armsInterventionsModule': {'armGroups': [{'label': 'NCS Vanguard cohort', 'description': 'Women of child bearing potential, children born to women enrolled in the study, the children s biological and/or social fathers, and primary caregivers (if other than parent)'}]}, 'contactsLocationsModule': {'locations': [{'zip': '60611', 'city': 'Chicago', 'state': 'Illinois', 'country': 'United States', 'facility': 'Northwestern University', 'geoPoint': {'lat': 41.85003, 'lon': -87.65005}}, {'city': 'Chicago', 'state': 'Illinois', 'country': 'United States', 'facility': 'NORC at the Univ. of Chicago', 'geoPoint': {'lat': 41.85003, 'lon': -87.65005}}, {'zip': '20892', 'city': 'Bethesda', 'state': 'Maryland', 'country': 'United States', 'facility': 'National Institute of Child Health and Human Development (NICHD), 9000 Rockville', 'geoPoint': {'lat': 38.98067, 'lon': -77.10026}}, {'zip': '20850', 'city': 'Rockville', 'state': 'Maryland', 'country': 'United States', 'facility': 'Westat, Inc.', 'geoPoint': {'lat': 39.084, 'lon': -77.15276}}], 'overallOfficials': [{'name': 'Jack Moye, M.D.', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD)', 'class': 'NIH'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
