The Society for Pediatric and Perinatal Epidemiologic Research (SPER)┬áis an organization of individuals from a wide variety of disciplines who share a common interest: the epidemiology of pregnancy, infancy and childhood. The objective of the Society is to foster pediatric and perinatal epidemiologic research. This research includes the study of any factors that influence maternal health and the health and development of children, from their conception through their adolescence. The Society was formed in 1988, and holds an annual meeting each June, immediately preceding the meeting of the Society for Epidemiologic Research (SER). The work presented at SPER’s annual meeting represents the cutting edge of research in pediatric and perinatal epidemiology.
