MRC Epidemiology Unit : Data Sharing PortalThe Fenland study is a population-based study designed to study the interaction between environment and genetic factors in determining intermediate quantitative traits related to obesity and type 2 diabetes risk including measures of insulin sensitivity and hyperglycaemia. The study is a cohort of 12,000 participants born between 1950 and 1975 (aged 30-62 years at recruitment) who have undergone detailed metabolic phenotyping with quantitative assessment of total and regional adiposity, diet and physical activity. The study commenced in 2005 and is still actively recruiting with phase 2 follow up beginning in 2014.

Fenland Data Releases
We originally formalised Fenland data releases around Release 3 (circa 2009). In 2010 Release 4 replaced it and a standardised data dictionary was established for the study. Since Aug 2013 Release 6 has been current and replaces all previous releases. Users should note that we are gradually rationalising variable names have been gradually rationalised between each release with some variable names being changed.
The data dictionary for Release 6 is the first publically shared data dictionary. A short history of previous releases is as follows - Release 1: contained approximately 1,500 participants and limited information of those.Release 2: contained the same 1,500 participants but incorporated the majority of the collected variables but minimal biochemistry details.Release 3: doubled the number of participants to approximately 3,000 and covered the majority of collected variables and some biochemistry details for the original 1,500 participants.Release 4: became available in October 2010 and contained records for 5000 participants and the first full data dictionary was created in March 2011, but was ammended and extended a number of times until March 2012.Release 5: updated the records to Aug 2012 and included information for 7970 participants.
