Explore data and samples
We have a vast number of samples and phenotypic, environmental, genetic and linkage data gathered from different cohort groups over the past 25 years.
We have published two papers detailing the ALSPAC cohort profile, as well as a short summary outlining recruitment and representativeness.
- Our data dictionary (zip file, 254MB) includes detailed information on all the data and samples we currently hold.
- Our variable catalogue (zip file, 2MB) includes every single ALSPAC variable name and label, grouped according to data source.
You may also like to use the searchable indexes of ALSPAC variables available on the CLOSER Discovery website – a search engine that allows you to explore the content of eight leading UK longitudinal studies, and provides metadata on phenotypic and environmental variables across those studies.
If we have the data and samples you require, you can request to access the data and samples for your own research.
Participants have completed a large number of questionnaires covering a wide range of topics.
Participants have provided data and samples via hands-on assessment in clinic at multiple time points.
Participants have donated a range of samples, including blood, urine, hair, nails, saliva and teeth.
Linkage to routine health and social records
Participant data has been linked with a variety of external data sources (for example, GP records, criminal and civic registration records).
Children of the Children of the 90s
Many of our original participants have become parents themselves. We are now collecting information about the health and lives of their children, extending ALSPAC to become a unique three-generation study.
