[Seasons and mortality in Italy: some ambiguous relationships and their geographic implications]

"A statistical analysis of mortality data during the current century in Italy reveals that the seasonal variation curve has undergone conspicuous chronological changes from decade to decade, the rates gradually evolving from a summer to winter maximum. But from [one] region to another the evolution started sooner or later and it is today more or less achieved. Moreover, while almost all countries in the world have come to show such moderateness as to be called deseasonality, i.e. a seasonal variation pattern nearly equal to a straight line, Italy is a sharp exception to this rule."
