Population growth and global health disparities for many reproductive and perinatal outcomes are but a few of the pressing issues facing public health today. Despite growing interest in the field, formal training in reproductive and perinatal epidemiology remains limited, with few available textbooks aimed at providing an overview of the field. In response to this need, faculty from theEunice Kennedy ShriverNational Institute of Child Health & Human Development (NICHD) and CIHR's Institute of Human Development, Child and Youth Health (IHDCYH) developed an intensive, competitive, Summer Institute in Reproductive and Perinatal Epidemiology. The curriculum of this Summer Institute has been developed into a textbook to provide students and researchers with a working knowledge of the substantive and methodologic issues underlying reproductive and perinatal epidemiology. Reproductive and Perinatal Epidemiologyoffers a core curriculum that addresses the epidemiology of major reproductive and perinatal outcomes. From human fecundity to birth and neonatal outcomes, the subject is approached from as international a perspective as possible, and the unique methodologic issues underlying each outcome are discussed. Developed by leading researchers in collaboration with their students in response to their needs and concerns, this is the definitive textbook on the subject.
