EPIC working groups
The Diabetes (InterAct) Working Group
In the EPIC study, diabetes is both an important exposure and an outcome of interest in itself. The Working Group has divided its attention between analyses involving the cases with prevalent diabetes at baseline and the investigation of the association of baseline factors with incident diabetes.
The incident cases were ascertained and verified in the European Union Sixth Framework Programme funded project InterAct, which involved 8 of the 10 countries in EPIC (see http://www.inter-act.eu/). The analyses are undertaken as a case—cohort study including 12 403 cases and a centre-stratified random subcohort of 16 154 individuals. In addition to analysing the association of lifestyle factors and incident diabetes, EPIC-InterAct has completed core biochemical measures, including phospholipid fatty acids, and has genome-wide genotype information on all individuals. Genome-wide methylation data, telomere length, and assays of vitamins D and C and carotenoids are under way. Metabolomic analyses are planned. The InterAct random subcohort is acting as the comparison group for other EPIC studies, including EPIC-Heart, EPIC-CVD, and Parkinson’s disease. Proposals for analyses using the data assembled in InterAct can be submitted via the website.
