The Million Women Study is the largest study of women’s health in the world. In 1996-2001, a quarter of UK women then aged 50-64 years (1.3 million women) joined the study. The aim of the study is to provide reliable information on potentially modifiable causes of common and serious illnesses, to help improve individual and public health. Study participants have provided details about their lifestyle and health and given signed consent for follow-up. Since recruitment their health has been followed mainly through electronic linkage to routinely collected NHS records (only 1.5% loss to follow-up after 20 years) and the whole surviving cohort has been re-contacted 4 times by postal re-survey to update exposures (1999-03, 2006-7, 2009-12 & 2013-14). Subsets of women have completed additional postal and online re-surveys.
Million Women Study is part of the Dementias Platform UK (DPUK), a multi-million pound public-private partnership to accelerate progress in dementias research http://www.mrc.ac.uk/research/facilities/dementias-platform-uk
