Half a million Britons have volunteered their DNA, lifestyle details, and medical histories for a study that now tracks their health across decades. This matters because most disease research relies on small, short-term studies or patient groups already diagnosed with illness. UK Biobank fills a gap by watching healthy people develop conditions over time—capturing early signals of cancer, heart disease, dementia, and other mid-to-late-life illnesses before symptoms appear. The resource already holds genetic data, physical measurements, imaging scans, and activity monitor records, all linked to participants’ long-term health outcomes. If the study continues, researchers worldwide will gain the statistical power to identify subtle risk factors and early disease markers that smaller studies miss. This could improve diagnosis of common conditions at earlier, more treatable stages, and support development of new treatments. The resource also underpins fundamental science—helping scientists understand the biological and environmental roots of disease across whole populations, not just in narrow clinical samples.

UK Biobank is supported by The Wellcome Trust, The National Institute of Health Research, The Medical Research Council, The British Heart Foundation and Cancer Research UK. The figures presented on this record represent the Medical Research Council funding contribution only with some additional UKRI Infrastructure funds in addition. UK Biobank is a prospective study of 500,000 men and women aged 40-69 years at the point of recruitment (2006-10). The study has collected extensive phenotypic and genotypic detail about its participants, including data from questionnaires, physical measures, sample assays, accelerometery, imaging, genome-wide genotyping and long-term longitudinal follow-up for a wide range of health-related outcomes. The resource is regularly augmented with additional data and is available to academic or commercial researchers world-wide to use for any type of health-related research that is in the public interest. It has been established primarily for the conduct of prospective studies investigating the relevance of a wide range of exposures to health outcomes that occur during long-term follow-up. The ongoing identification and adjudication of increasing numbers of incident cases of the commoner conditions in the resource will support extensive and powerful research into their determinants and the range of diseases that can be studied reliably will widen as the numbers of incident events of different types increase during follow-up over the next 5-10 year period. As a result, UK Biobank provides researchers from around the world with greater opportunities to better understand early disease stages and their diagnosis, and can support the development of new treatments for diseases of mid-to-later life.
