✦ Synopsis

hi this article a hasic distinction is made between etiologic and prevention ejfectiveness intervention studies. Etiologic intervention studies ,focus on elucidating causes of disease, while the purpose q f preL,ention effectiveness intervention studies is to study methods of prevention. The design requirements ,for each ?f these studie.y are veni different: etiologic intervention studies usually need large study populations, large exposure contrasts, ascertainment of exposure, as well as health outcome. Idecrlly, randomization und blinding should also be applied. Effective preventive strategies may, on the other hand, be identified in small study populations with exposure as the only outcome measure, and randomization and blinding incry be .superfluous. At present, intervention studies are in great demand. arid ofen there is a wish that eriologic questions as well as prevention effectiveness be uddressed in the .same study. We argue that this should not be done without careful consideration O f possible conflicting design aspects.
