Introduction: several studies have reported significant associations between outdoor air pollution and health outcome, such as deaths and hospital admissions for respiratory and cardiovascular diseases. Objectives: to analyse the short-term effects of air pollutants levels on hospital admissions for respiratory and cardiovascular diseases occurred in Massa-Carrara (Italy) during 2005-2009. Methods: hospital admissions for respiratory and cardiovascular diseases, ambient air pollution data (PM10, NO2, O3 and CO) and meteorological parameters were collected from July 2005 to December 2009 in the area of Massa-Carrara, northern Tuscany (Italy). A time-stratified case-crossover design was implemented and conditional regression models were fitted, adjusting for meteorological data and a set of time-dependent variables. The associations between exposure and hospitalised events were analysed taking into account different lag patterns in order to evaluate immediate or delayed effects of pollutants. Stratified analyses were conducted to identify more susceptible subgroups. Results: 7,931 admissions in local hospitals for respiratory diseases and 18,521 for cardiovascular diseases were identified for residents in Massa-Carrara. Respiratory hospital admissions were associated to 0,1 mg/m3 increase in CO (OR=1.035 95%CI= 1.017-1.053, lag0), to 10 µg/m3 PM10 increase during warm season (OR=1.05 CI=1.01-1.10, lag 4); children (0-14 years) respiratory admissions were associated to NO2 (OR=1.14 CI=0.979-1.343, lag1) and to O3 (OR=1.09 CI=1.01-1.17, lag3). Cardiovascular admissions were associated to NO2 (OR=1.029 CI=1.004-1.056, lag0), to PM10 (OR=1.029 CI=1.001-1.058, lag1) and to CO (OR=1.035 CI= 1.005-1.067, lag4) during warm season. Conclusions: this study confirmed the adverse effects of outdoor air pollution on cardiovascular and respiratory health. Elder people and children had higher risks of disease, mainly during warm season.

Abstract

Introduction: several studies have reported significant associations between outdoor air pollution and health outcome, such as deaths and hospital admissions for respiratory and cardiovascular diseases. Objectives: to analyse the short-term effects of air pollutants levels on hospital admissions for respiratory and cardiovascular diseases occurred in Massa-Carrara (Italy) during 2005-2009. Methods: hospital admissions for respiratory and cardiovascular diseases, ambient air pollution data (PM10, NO2, O3 and CO) and meteorological parameters were collected from July 2005 to December 2009 in the area of Massa-Carrara, northern Tuscany (Italy). A time-stratified case-crossover design was implemented and conditional regression models were fitted, adjusting for meteorological data and a set of time-dependent variables. The associations between exposure and hospitalised events were analysed taking into account different lag patterns in order to evaluate immediate or delayed effects of pollutants. Stratified analyses were conducted to identify more susceptible subgroups. Results: 7,931 admissions in local hospitals for respiratory diseases and 18,521 for cardiovascular diseases were identified for residents in Massa-Carrara. Respiratory hospital admissions were associated to 0,1 mg/m3 increase in CO (OR=1.035 95%CI= 1.017-1.053, lag0), to 10 µg/m3 PM10 increase during warm season (OR=1.05 CI=1.01-1.10, lag 4); children (0-14 years) respiratory admissions were associated to NO2 (OR=1.14 CI=0.979-1.343, lag1) and to O3 (OR=1.09 CI=1.01-1.17, lag3). Cardiovascular admissions were associated to NO2 (OR=1.029 CI=1.004-1.056, lag0), to PM10 (OR=1.029 CI=1.001-1.058, lag1) and to CO (OR=1.035 CI= 1.005-1.067, lag4) during warm season. Conclusions: this study confirmed the adverse effects of outdoor air pollution on cardiovascular and respiratory health. Elder people and children had higher risks of disease, mainly during warm season.
