The Avon Longitudinal Study of Parents and Children (ALSPAC), also known as Children of the 90s and formerly the Avon Longitudinal Study of Pregnancy and Childhood, is a cohort study of children born in the former county of Avon, England during 1991 and 1992.[1] It is used by researchers in health, education and other social science disciplines.

The study is hosted at the University of Bristol and was initially led by Jean Golding and is now directed by George Davey Smith.[2] The initial recruits were 15,247 pregnant women with estimated dates of delivery between April 1991 and December 1992. Since then the fathers, siblings and children of the participants have also begun to be studied.[1]

It is one of a family of similar studies that were set up at around the same time in six countries across Europe, known as the European Longitudinal Study of Pregnancy and Childhood (ELSPAC). ELSPAC included studies in Czechoslovakia[3] and the Isle of Man,[4] in addition to ALSPAC.
