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. There are several ways you can explore this resource.
- Index of Multiple Deprivation (IMD) Scores - includes those for housing, income, employment, child poverty, health, crime and disorder and living environment – linked to mothers (G0) and young people (G1) available annually and for all questionnaire and clinic data collected up to 2014.
- Tanning and sun exposure data collected as part of the Life@25+ questionnaire (YPE).
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, 278MB) includes detailed information, including frequencies, on all the data that are currently available.
- Our variable catalogue (zip file, 2MB) is a simple list of all ALSPAC variable names and labels that are available, grouped according to data source and timepoint.
- Our variable search tool allows simple searching across variable names and labels to help with identifying what data might be available.
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.
A number of ALSPAC datasets can be accessed externally, without the need for project proposals or exec permission, for specific research or for training purposes. A list is available here.
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.
Children of the 90s (ALSPAC) study history
More than 1,000 boxes of records documenting the ALSPAC study from its early planning stages in the 1980s to the mid 2000s, including hard copies and electronic records.
Natural and built environment data
Data have been collected relating to participants natural and built environment. Additional environmental exposure data can be linked using geocoded lifecourse residential addresses.
