The Whitehall II cohort was established in 1985 and enlisted 10 308 (6895 male and 3413 female) civil servants aged 34–55 years who worked in the offices of 20 Whitehall departments 15. Initial measurements were obtained between 1985 and 1988 via a self‐administered questionnaire and clinical examination. Participants were then followed‐up at regular intervals to produce 11 phases of data by 2012–13. The University College London Medical School Committee on the ethics of human research approved the Whitehall II study. Whitehall II data are available to bona fide researchers for research purposes.
