title: [Depopulation of rural districts and mental health: the Sassim study (author's transl)].
abstract: The present investigation is a study of mental diseases in Sassim, a little rural district near Pavia (Italy), in which there has been an intensive process of depopulation during the last 20 years. In this communication the A.A. discuss the first phase of the study: they have investigated the demographic development of population from 1960 to 1977 and prevalence as well as incidence rates of mental diseases. Depopulation hasn't been only quantitative, but has altered the structure of population and has presented a quite different decrease velocity during the examined period; the trends of psychiatric morbidity seem to be associated with the distinctive feature of depopulation.
