The Collaborative Perinatal Project (abbreviated CPP), also known as the National Collaborative Perinatal Project (or NCPP), was a multisite prospective cohort study designed to identify the effects of complications during either pregnancy or the perinatal period on birth and child outcomes, especially neurological disorders such as cerebral palsy.[1] It was conducted by the National Institute of Neurological and Communicative Disorders and Stroke on over 55,000 pregnant mothers at 12 sites across the United States from 1959 to 1965.[2] It is one of the largest and broadest epidemiological studies in American history; according to Mark Klebanoff, "No U.S.-based study of pregnancy and childhood conducted before or since has matched its size, breadth and depth".[3]
