Meta-analysis of the Italian Studies of Short-term Effects of Air Pollution (MISA), 1990–1999

Abstract

A meta-analysis of short-term effects of air pollution on health in eight Italian cities from 1990 to 1999 is presented. Death certificates and hospital admission data as well as daily concentrations of pollutants were collected. The same generalized linear model adjusted for age, day of the week, holidays, influenza epidemics, meteorological variables, and seasonality pattern was fitted to the city data. City-specific model selection was not done. In the meta-analysis, for each outcome, the city-specific estimates for each pollutant were combined using fixed and random-effects models. Hierarchical Bayesian models were use to investigate the effects of PM10 in detail. Each pollutant (SO2, NO2, CO, PM10, O3) was significantly associated with mortality for natural causes. The effect of PM10 on mortality was greater during the warm season and for elderly. A north-south gradient in risk was observed for total natural mortality. The excess risks on hospital admission were modified by deprivation score and by the NO2/PM10 ratio. Results add evidence for an association between air pollution and early mortality or morbidity and support the hypothesis of a synergism between meteorological variables and air pollution.

An evaluation of hospital admission respiratory disease attributed to sulfur dioxide ambient concentration in Ahvaz from 2011 through 2013

“…Previous study showed that an increase of 10 μg/m 3 in SO 2 was associated with an increase of 2.4 % in hospital admissions respiratory cases in six Italian cities (Biggeri et al 2001).…”

Short‐term effects of air pollution on cardiovascular diseases: outcomes and mechanisms

“…Typically, short-term mortality rates, hospital admissions and emergency room visits for exacerbations of existing symptoms did increase in relation to variations in air pollution (time-series studies). A recent update of the Meta-analysis of Italian Studies on the short-term effects of Air pollution [21], that considered data on 9 million people from 15 Italian cities for the period 1996-2002, showed that cardiorespiratory mortality increased with increasing concentrations of air pollutants (for NO 2 0.40%, for CO 0.93%, for SO 2 1.11% and for PM 10 0.54%). Similar results were obtained in studies carried out in French and Spanish urban areas [22][23][24].…”

Caracterización del ambiente atmosférico en Las Palmas de Gran Canaria y Santa Cruz de Tenerife: 2000 a 2004

“…La asociación del material particulado con la salud ha sido ampliamente estudiada en las ciudades europeas, norteamericanas y asiáticas [17][18][19][20][21][22][23][24][25] . En general, los resultados de estos estudios son consistentes en el sentido de que la gran mayoría de ellos encuentran una asociación significativa en el corto plazo (es decir, entre el mismo día de la exposición y unos pocos días después) con los indicadores de mortalidad y morbilidad.…”
