Epidemiological research shows that disease aetiology often has to be evaluated with a life-course perspective,1 starting as close to the time of conception as possible2 and, furthermore, that genetic predisposition, environmental exposures, and social context have to be considered simultaneously.
Several birth cohorts have been established in Europe in the last decades and more are being planned. In total, the established birth cohorts encompass approximately 300 000 children and their parents. There are at least three reasons why these cohorts should work closely together and facilitate the use of these data on a collaborative basis. The first and most obvious reason is to increase statistical power. The second is efficient design since a large study population in many countries will allow selective sampling by exposure
Birth cohorts in the EU: fait accompli
Why should we collaborate? Statistical power
Why should we collaborate? Efficient design: sampling from the EU population
Why should we collaborate? Replication of findings
How could we achieve collaboration: a virtual European mega birth cohort
