Data Release v19 – March 2025

Questionnaire data 

• Sleep questionnaire: Data for approximately 180,000 participants from our sleep questionnaire, exploring sleep behaviour, patterns and quality, as well as contributing factors and consequences of poor sleep. See Category 205

• Updates to fluid intelligence data: Corrected scores and counts for questions attempted within the time limit for both online and touchscreen versions of the fluid intelligence questionnaire. Updated fields: 20016, 20191, 20128.

Imaging data

• Brain image and imaging-derived phenotypes update:

  • Derived tabular and image outputs: Updates for approximately 15,000 participants are provided in Category 508 for derived tabular and image outputs from the UK Biobank brain imaging pipeline.

  • Cortical surface mapping: Task and resting state MRI data are now mapped to the structure of the cortical surface for over 63,000 datasets. This mapping supplements the volumetric-based derivations currently available, providing a more accurate functional correspondence of brain regions between participants. This is provided in Category 198.

• Release of carotid ultrasound images in more accessible format: All carotid ultrasound images (approx. 80,000 participants) converted to a more accessible .mat format in Field 20241.

Genetic data

• Polygenic risk score update 2024: Version 2 of polygenic risk scores for 28 diseases and 25 quantitative traits in Category 300.

• DRAGEN population VCFs: Updated machine-learning corrected VCF data (pVCF) for all 500,000 participants, improving genome data accuracy, in Field 24311.

• DRAGEN PLINK2 format: New PLINK2 format genetic data for all 500,000 participants in Field 24308, derived from the updated pVCF released in Field 24311.

• DRAGEN BGEN format: New BGEN format genetic data for all 500,000 participants in Field 24309, derived from the updated pVCF released in Field 24311.

• Whole genome sequencing (WGS) sample visit collection: Updated quality control (QC) data for WGS, specifying which visit the sequenced sample was collected from, in Category 187. Note that the values within the QC fields themselves remain unchanged.

Healthcare records

• Death data for England, Scotland and Wales: Updated death records for England, Scotland, and Wales in Category 100093 and the associated record-level tables.

Environmental data

• Updated location at assessment (coordinates and small-area fields): Updated data on participants' residential locations at time of assessment, with standardised geocoding methods, new location data for recent assessments, and added census area information for follow-up visits.

• Residential location data - address history: Older fields for home location history in Category 150 replaced to correct inaccuracies. We strongly advise researchers to request the new fields and update your pipelines accordingly. The older fields will be retired at the next release. More details here.

Physical measurements

• VO2max during exercise: VO2max estimates (per kg bodyweight) from personalised exercise tests for 80,000 participants in Category 267.

Biomarker data

• Integrated herpes viruses: Data on inherited chromosomally-integrated human herpesvirus-6 (HHV-6) for all 500,000 participants in Category 268.

OMOP common data model

• Restriction of OMOP data tables: Restriction of the OMOP derivation dataset due to quality issues identified by research groups. Researchers can still request access by contacting the Access team. Please review this article We are looking into the demand for converting UK Biobank data into common data models, such as OMOP, to make them more accessible and useful for researchers. Complete this short survey to share your thoughts and help guide our efforts.

Invitation data

• Invitation dates for online questionnaires: New data fields added for invitation dates to complete the following online questionnaires: digestive health, experience of pain, food preferences, mental health, and work environment. Assessment centre invitation dates and responses will also be updated to include data for participants who attended the first repeat assessment visit (2012-13)

UK Biobank assessment centre data

• Tabular and bulk: Fields under Category 100000, including brain, cardiac, and abdominal MRI DICOM images are being updated with datasets for an additional 13,000 participants. This category also includes data for cognitive function fields, the verbal interview, physical measures (including ECG), and raw OCT and retinal fundus data.

• Fix to dates at imaging assessment: We have identified a technical error which caused a small number of imaging assessment dates (<100 records) to be recorded incorrectly. Error corrected and a fix implemented to prevent reoccurrence. Fields derived from assessment date (month of assessment and age at assessment) have also been corrected. See Category 100024.
