The National Environmental Remediation programme in Italy includes sites with documented contamination and associated potential health impacts (National Priority Contaminated Sites—NPCSs). SENTIERI Project, an extensive investigation of mortality in 44 NPCSs, considered the area of Taranto, a NPCS where a number of polluting sources are present. Health indicators available at municipality level were analyzed, that is, mortality (2003–2009), mortality time trend (1980–2008), and cancer incidence (2006-2007). In addition, the cohort of individuals living in the area was followed up to evaluate mortality (1998–2008) and morbidity (1998–2010) by district of residence. The results of the study consistently showed excess risks for a number of causes of death in both genders, among them: all causes, all cancers, lung cancer, and cardiovascular and respiratory diseases, both acute and chronic. An increased infant mortality was also observed from the time trends analysis. Mortality/morbidity excesses were detected in residents living in districts near the industrial area, for several disorders including cancer, cardiovascular, and respiratory diseases. These coherent findings from different epidemiological approaches corroborate the need to promptly proceed with environmental cleanup interventions. Most diseases showing an increase in Taranto NPCS have a multifactorial etiology, and preventive measures of proven efficacy (e.g., smoking cessation and cardiovascular risk reduction programs, breast cancer screening) should be planned. The study results and public health actions are to be communicated objectively and transparently so that a climate of confidence and trust between citizens and public institutions is maintained.
Introduction. Although the long-term effect of air pollution on mortality has been well studied, the health effects of industrial emissions are less clear and the relevant time-windows of exposure must be established. We conducted a cohort study to examine the association between residential exposure to air pollution from a large steel plant (ILVA), located in Taranto (South Italy) and cause-specific mortality. Methods. The cohort included all (321,356 subjects) residents in the area in 1998, followed until 2013. Exposure to PM10 and SO2 originating from the steel plant at each residential address in 2010 was assigned using a Lagrangian dispersion model. A backward (and forward) extrapolation back to 1965 was done on the basis of industry steel production, emission data, and the spatial pattern of pollutants. The time-dependent annual average exposure and the cumulative exposure of the last 35 years were used in Cox proportional-hazard models to investigate the effect of industrial air pollutants on mortality. The latency of effects was explored with distributed-lag models. Results. A total of 33,042 subjects died from natural causes by the end of the follow-up period. Both industrial PM10 and SO2 at lag 0 were associated with natural mortality: HR 1.04 (95% Confidence Interval (CI):1.02-1.06) and 1.09 (95%CI:1.05-1.12) for each 10µg/m3, respectively. Stronger associations were observed for heart diseases (HR 1.05 for PM10 and 1.11 for SO2) and acute myocardial infarction (HR 1.10 for PM10 and 1.29 for SO2). Similar effects were found with the 35-year cumulative exposure. The distributed-lag models for natural mortality showed that the effects were due to both the recent exposure (previous 5 years) and the exposures in the distant past (30-35 years lag). Conclusions. Concurrent and cumulative exposures to industrial PM10 and SO2 were associated with mortality in the cohort. Both recent and distant exposures are responsible for the negative effects on mortality.
Green spaces have been shown to be beneficial to humans, but quantifying these benefits is a challenge for epidemiology. In this health impact assessment study, we exploit satellites to estimate for the whole of Italy the number of deaths that could be prevented in the 49 million adult population by greening residential areas. The exposure was assessed by calculating the normalized difference vegetation index at 10-m resolution within a 300-m distance from homes in 7904 municipalities. In this study we estimate, by achieving nationwide the level of residential greenness currently reached by the 25% of the population, a total of 28,433 (95% confidence interval: 21,400–42,350) preventable deaths and 279,324 (210,247–415,980) preventable years of life lost in Italy in 2022, representing the 5% of the total mortality burden. More green means fewer deaths, thus strong action is needed to increase the amount and accessibility of green spaces in all human settlements. Green spaces are beneficial to humans. The authors estimate, by reaching across the whole of Italy the greenness currently achieved by the 25% of the population, a total of 28,433 annual preventable deaths, representing the 5% of all mortality burden.
Studies have analyzed the effects of industrial installations on the environment and human health in Taranto, Southern Italy. Literature documented associations between different variables and dementia mortality among both women and men. The present study aims to investigate the associations between sex, environment, age, disease duration, pandemic years, anti-dementia drugs, and death rate.
This is an update of incidence and mortality cancer data provided by the Italian Network of Cancer Registry (AIRTUM) relative to the period 2003-2005.AIRTUM is a network of general and specialized population-based cancer registries that covers about 1/3 of the Italian resident population (www.registri-tumori.it). Incidence and mortality data for the period 2003-2005 are based on 20 Registries. The five most frequently diagnosed cancers were: - prostate (18.5%), non melanoma skin (15.8%), lung (13.1%), colorectal (12.0%), bladder (5.7%) among males; - breast (24.9%), non melanoma skin (15.1%), colorectal (11.9%), lung (5.0%) and stomach (4.1%) among females. In the same period the most frequent causes of cancer death were: - cancer of the lung (27.6%), colorectal (10.7%), prostate (8.5%), stomach (7.3%) and liver (6.1%) among males; - breast cancer (16.3%), colorectal (11.9%), lung (10.3%), stomach (7.2%) and pancreas (6.5%) among females. According to the age-specific incidence rates one man and one woman every two will receive a cancer diagnosis during his/hers life (from birth to the age of 84 years). From 1993-1995 to 2003-2005, overall crude cancer incidence rate (males and females together) increased from 555.4 to 654.8 x 100,000. Standardization showed that 63% of this increase was due to ageing of the population. Moreover, most of the residual increase was among those cancer sites (breast, prostate, colorectal, thyroid and melanoma) for which early detection may have played a relevant role in anticipating (and therefore increasing) the number of diagnoses. Due to population ageing also overall cancer mortality did not show any decrease when crude rates were compared. On the contrary, standardized mortality rates (all cancers together) showed a strong decrease (311.4 vs. 266.5 x 100.000). The risk of receiving a diagnosis or dying because of cancer is still lower in residents in the regions of the South of Italy than in those of Central and Northern Italy, but they are becoming more and more similar. In Italy cancer incidence and mortality rates are similar to those in northern European countries and in USA among males, but they are still lower for women.
A large steel plant close to the urban area of Taranto (Italy) has been operating since the sixties. Several studies conducted in the past reported an excess of mortality and morbidity from various diseases at the town level, possibly due to air pollution from the plant. However, the relationship between air pollutants emitted from the industry and adverse health outcomes has been controversial. We applied a variant of the "difference-in-differences" (DID) approach to examine the relationship between temporal changes in exposure to industrial PM10 from the plant and changes in cause-specific mortality rates at area unit level.We examined a dynamic cohort of all subjects (321,356 individuals) resident in the Taranto area in 1998-2010 and followed them up for mortality till 2014. In this work, we included only deaths occurring on 2008-2014. We observed a total of 15,303 natural deaths in the cohort and age-specific annual death rates were computed for each area unit (11 areas in total). PM10 and NO2 concentrations measured at air quality monitoring stations and the results of a dispersion model were used to estimate annual average population weighted exposures to PM10 of industrial origin for each year, area unit and age class. Changes in exposures and in mortality were analyzed using Poisson regression.We estimated an increased risk in natural mortality (1.86%, 95% confidence interval [CI]: -0.06, 3.83%) per 1 μg/m3 annual change of industrial PM10, mainly driven by respiratory causes (8.74%, 95% CI: 1.50, 16.51%). The associations were statistically significant only in the elderly (65+ years).The DID approach is intuitively simple and reduces confounding by design. Under the multiple assumptions of this approach, the study indicates an effect of industrial PM10 on natural mortality, especially in the elderly population.
to estimate the prevalence of chronic obstructive pulmonary disease (COPD) by integrating various administrative health information systems.prevalent COPD cases were defined as those reported in the hospital discharge registry (HDR) and cause of mortality registry (CMR) with codes 490*, 491*, 492*, 494* and 496* of the International diseases classification 9th revision. Annual prevalence was estimated in 35+ year-old residents in six Italian areas ofb different sizes, in the period 2002-2004. We included cases observed in the previous four years who were alive at the beginning of each year.in 2003, age-standardized prevalence rates varied from 1.6% in Venice to 5% in Taranto. Prevalence was higher in males and increased with age. The highest rates were observed in central (Rome) and southern (Taranto) cities, especially in the 35-64 age group. HDR contributed 91% of cases. Health-tax exemption registry would increase the prevalence estimate by 0.2% if used as a third data source.with respect to the National Health Status survey, COPD prevalence is underestimated by 1%-3%; this can partly be due to the selection of severe and exacerbated COPD by the algorithm used. However, age, gender and geographical characteristics of prevalent cases were comparable to national estimates. Including cases observed in previous years (longitudinal estimates) increased the point estimate (yearly) of prevalence two or three times in each area.
Introduction In Taranto, Southern Italy, adverse impacts on the environment and human health due to industrial installations have been studied. In the literature, associations have been reported between gender, environmental factors, and lung cancer mortality in women and men. The aim of this study was to investigate the relationships between gender, residence in areas with high environmental pressures, bronchus/lung cancer characteristics, and death rate. Methods Data from the Taranto Cancer Registry were used, including all women and men with invasive bronchus/lung cancer diagnosed between 1 January 2016 and 31 December 2020 and with follow-up to 31 December 2022. Bayesian mixed effects logistic and Cox regression models were fitted with the approach of integrated nested Laplace approximation, adjusting for patients and disease characteristics. Results A total of 2,535 person-years were observed. Male gender was associated with a higher prevalence of histological grade 3 (OR 2.45, 95% CrI 1.35–4.43) and lung squamous-cell carcinoma (OR 3.04, 95% CrI 1.97–4.69). Variables associated with higher death rate were male gender (HR 1.24, 95% CrI 1.07–1.43), pathological/clinical stage II (HR 2.49, 95% CrI 1.63–3.79), III (HR 3.40, 95% CrI 2.33–4.97), and IV (HR 8.21, 95% CrI 5.95–11.34), histological grade 3 (HR 1.80, 95% CrI 1.25–2.59), lung squamous-cell carcinoma (HR 1.18, 95% CrI 1.00–1.39), and small-cell lung cancer (HR 1.62, 95% CrI 1.31–1.99). Variables associated with lower death rate were other-type lung cancer (HR 0.65, 95% CrI 0.44–0.95), high immune checkpoint ligand expression (HR 0.75, 95% CrI 0.59–0.95), lung localization (HR 0.73, 95% CrI 0.62–0.86), and left localization (HR 0.85, 95% CrI 0.75–0.95). Discussion The results among patients with lung cancer did not show an association between residence in the contaminated site of national interest (SIN) and the prevalence of the above mentioned prognostic factors, nor between residence in SIN and death rate. The findings confirmed the independent prognostic values of different lung cancer characteristics. Even after adjusting for patients and disease characteristics, male gender appeared to be associated with a higher prevalence of poorly differentiated cancer and squamous-cell carcinoma, and with an increased death rate.
