Un modelo genetico-ambiental para un estudio prospectivo del estado de salud de los ciudadanos italianos en la Argentina Parte 1. Descripción del método y estadísticas generales sobre poblaciones

The project is born from the hypothesis, today quite accredited, that many diseases are the result of the interaction of genetic and environmental factors.From this hypothesis is born the idea of studying through a natural model the different impact that the environment can have on the modification of the natural history of some diseases. The natural model that most easily meets the methodological requirement is that of the emigrated population and established in an environment very different from that of origin. In a quick analysis emerges that the model of the Italians emigrated to Argentina can respond to this pretension: environment and seasons inverted, different food lifestyle, diverse social structure, low rate of return, significant migratory flow between the years 1920 and 1960 which guarantees a sufficiently long environmental exposure period
