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.

New data

Focus@24+ Clinic data
For two years (2015-2017) over 4,000 ALSPAC young people took time out to visit us and take part in the Focus@24+ Clinic. We are delighted to announce that data is now available for researchers to use. This first release includes blood pressure, weight, height, measurements, lung function, reproductive health data and more.

Life@24+ Questionnaire data
Over 4300 young people completed this questionnaire which includes questions about eating, weight, exercise, smoking, gambling, social media, self-harm and e-cigarettes.

A full description of all the new data with frequencies is available in the data dictionary (zip file, 323MB).

Cohort profile

We have published two papers detailing the ALSPAC cohort profile, as well as a short summary outlining recruitment and representativeness.

Existing data

  • 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.
