[Methods for mortality analysis in SENTIERI Project].

The methods of mortality analysis in Italian polluted sites (IPS) are described. The study concerned 44 IPSs; each one included one or more municipalities. Mortality at municipality level was studied in the period 1995-2002, using the following indicators: crude rate, standardized rate, standardized mortality ratio (SMR), and SMR adjusted for an ad hoc deprivation index. Regional populations were used as reference for indirect standardization. The deprivation index was constructed using the 2001 national census variables representing the following socioeconomic domains: education, unemployment, dwelling ownership, overcrowding. Mortality indicators were computed for 63 single or grouped causes. The results for all the 63 analysed causes of death are available for each IPS, and in this Chapter the results for each IPS for causes selected on the basis of a priori evidence of risk from local sources of environmental pollution are presented. The procedures and results of the evidence evaluation have been published in the 2010 Supplement of Epidemiology & Prevention devoted to SENTIERI.
