Avon Longitudinal Study of Parents and Children

Children of the 90s

Avon Longitudinal Study of Parents and Children (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.

Based at the University of Bristol, the ALSPAC is a world-leading birth cohort study. Between April 1991 and December 1992 more than 14,000 pregnant women were recruited 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.

Management and funding

ALSPAC is funded by the Medical Research Council, the Wellcome Trust and the University of Bristol. It is managed by a team based at the University of Bristol which is led by the scientific director, Professor George Davey Smith, and Lynn Molloy, the executive director.

Accessing the data

ALSPAC has governance and access arrangements that comply with MRC data sharing policy. The data is accessible to bona fide researchers by applying through the ALSPAC website.

The ALSPAC website provides copies of the questionnaires and documentation used in the study. The website also provides a data dictionary and a variable catalogue, to help users make a formal request for data.
