Based at the University of Bristol, the Avon Longitudinal Study of Parents and Children (ALSPAC), also known as Children of the 90s, is a world-leading birth cohort study.

Between April 1991 and December 1992 we recruited more than 14,000 pregnant women into the study and these women (some of whom had two pregnancies or multiple births during the recruitment period), the children arising from the pregnancy, and their partners have been followed up intensively over two decades.

"Because ALSPAC has collected a wealth of information across a wide range of indicators of health outcomes and risk processes, it represents a wonderful resource that is open for all researchers." -Editorial, Journal of Child Psychology and Psychiatry, June 2012

ALSPAC is the most detailed study of its kind and provides a rich resource for the study of the environmental and genetic factors that affect health and development. Through our research we aim to inform policy and practices that will provide a better life for future generations.

How we are funded

We receive core funding from the UK Medical Research Council, the Wellcome Trust and the University of Bristol and additional support from many other funders for individual projects.

How we are run

Our scientific director, Professor George Davey Smith, leads the team, and our executive provides scientific direction and meets regularly to discuss new research proposals. Day to day, the study is managed by Lynn Molloy, the executive director. Since the outset, we have had our own ethics committee, which comprises clinicians, researchers, lawyers and lay people, including study participants. We involve participants in many aspects of the study and they have their own advisory panels and online discussion forums.
