Environmental justice nel sistema di sorveglianza epidemiologica SENTIER

OBJECTIVES: descriptive evaluation of distributional justice in the epidemiological surveillance system of populations residing in Italian National priority Contaminated Sites (NPCSs) of SENTIERI project. Analysis of the feasibility of monitoring different Environmental Justice dimensions in SENTIERI.

DESIGN: descriptive study and ecological meta-analysis. SETTING AN PARTICIPANTS: residents in 298 municipalities included in 44 NPCSs in SENTIERI. Description of their level of deprivation and mortality analysis by deprivation level in the first period evaluated in SENTIERI, years 1995-2002.

MAIN OUTCOME MEASURES: an index of multiple deprivation at municipality level DI-SENTIERI, built using 4 indicators based on variables from the Italian 2001 Census, was used to describe deprivation in communities living in NPCSs. The risk of mortality for all causes and all tumors in the pool of NPCSs municipalities by deprivation level was assessed using meta-Standardized Mortality Ratios (meta-SMRs).

RESULTS: sixty percent of municipalities (No. 179) in NPCSs belong to the two more deprived quintiles. The socioeconomic disadvantage of communities resident in NPCS has a North-South gradient: the proportion of municipalities belonging to the two more deprived quintiles is 29% in the North, 68% in the Centre, 92% in the South. Meta-SMRs for all causes in less deprived municipalities were 98 (90%CI 95-100) in men e 101 (90%CI 97-104) in women, the values for all cancers were 99 (90%CI 94-103) in men and 100 (90%CI 95-105) in women. The corresponding estimates in more deprived municipalities were, respectively in men and women, 103 (90%CI 101- 104) and 102 (90%CI 100-104) for all causes, 104 (90%CI 102-106) and 102 (90%CI 100-104) for all cancers.

CONCLUSIONS: residents in NPCSs are exposed to environmental stressors and are generally more deprived. The socioeconomic disadvantage is mostly affecting Central and Southern Italy populations. Furthermore, in these deprived communities the risk of mortality for all diseases and all cancers is higher. Populations living in NPCSs are affected by distributional injustice. To monitor the different dimensions of Environmental Justice, the DI-SENTIERI should be developed and other socioeconomic indicators implemented.
