A major scientific challenge for the next few decades is to understand the interaction between genetic susceptibility and environmental factors in the aetiology of chronic diseases. The most promising approach to discover these interactions requires a combined effort of epidemiology and molecular genetics and large sample sizes for sufficient power. Already in the early 90s, the European Prospective Investigation Into Cancer and Nutrition (EPIC) was initiated in 10 European countries to create a large cohort to study the aetiology of chronic diseases.1,2 The Netherlands has contributed two cohort studies to EPIC: the Prospect cohort of 17 357 women of the Julius Center3 in Utrecht, and the Monitoring Project on Risk Factors for Chronic Diseases (MORGEN) cohort of 22 654 men and women of the National Institute for Public Health and the Environment (RIVM) in Bilthoven.4 In the design phase, both cohorts collaborated closely to obtain maximal synergy in the design
