The NCPP data constitute an important resource for biomedical and behavioral research in many areas of obstetrics, perinatology, pediatrics, and developmental psychology. The data also provide a prospective base for examining neurological and neurosensory defects and the relationship of pregnancy and perinatal factors on the health of individual children. The major categories of data collected include obstetrical, pediatric, pathological, serological, socioeconomic and family, genetic history, psychological, speech, language, and hearing. The mother was examined during pregnancy, labor, and delivery. The children were given neonatal examinations and follow-up examinations at four, eight, and twelve months, and three, four, seven, and eight years. Supplemental information was gathered throughout the study, including family linkages between related women participating in the NCPP. There are 6,700 data items on the approximately 58,000 study pregnancies.

Further information about the history of the study and some of the preliminary results may be found in The Collaborative Perinatal Study of the National Institute of Neurological Diseases and Stroke: The Women and Their Pregnancies (U.S Department of Health Education and Welfare, Public Health Service, National Institutes of Health, 1972, DHEW Publication No. (NIH) 73-379).
