CPP Pathway Study

DDE & PCBs in the Collaborative Perinatal Project

DDE & PCBs in the Collaborative Perinatal Project

This collection incorporates both prospective and retrospective data on three generations of families initially living in inner-city Baltimore, Maryland. The prospective data were selected from data collected as part of the Johns Hopkins Collaborative Perinatal Study (JHCPS), a survey of pregnant women seeking prenatal care and delivery at Johns Hopkins Hospital during 1960-1964. JHCPS studied these women (the first-generation mothers, abbreviated as G1) and the children born to them during 1960-1965 (the second-generation children, abbreviated as G2) until the children were eight years old. The retrospective data comes from a follow-up study, conducted in 1992-1994, of G1, G2, and the children born to G2 (the third-generation children, abbreviated as G3).
