Avon Longitudinal Study of Parents and Children

The Avon Longitudinal Study of Parents and Children, 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. 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. The initial recruits were 14,000 pregnant women with estimated dates of delivery between April 1991 and December 1992.
