[Epidemiologic Study of Mortality during summer 2003 in Italy].

Following the unusually hot summer this year and the dramatic news from neighboring countries such as France, the Italian Minister of Health requested an epidemiologic mortality study during summer 2003, to investigate whether there had been an excess of deaths in Italy, particularly for the elderly population. Communal offices, which provide vital statistics, were asked for the number of deaths among resident people, occurred from June 1 to August 31, for 2003 and 2002, for the 21 Italian regions capitals. A mortality increase of 3,134 deaths was observed for 2003; most of them (92%) were people aged 75 years and older. The highest increases were observed in the North Western cities (Turin, Milan, Genoa). The relationship between mortality and climatic indexes (T. max, Humidex) was investigated and a clear correlation was observed.
