Differential susceptibility according to gender in the association between air pollution and mortality from respiratory diseases

Abstract

This study analyzed the association between air pollution and deaths from respiratory diseases, considering differential susceptibility according to gender. The authors used daily deaths from respiratory diseases (ICD-10, J00-J99), PM10, SO2, and O3 levels, and meteorological indicators in Volta Redonda, Rio de Janeiro State, Brazil, from January 2002 to December 2006. The association was estimated by Poisson regression using generalized additive models, where the increase in risk of deaths from PM10 to lag 1 was 10.01% (95%CI: 1.81-18.88%) in the total female population and 10.04% (95%CI: 0.90-20.02%) in elderly women. The increase in risk of deaths from PM10 to lag 9 was 8.25% in the total male population (95%CI: 0.86-16.18%) and 10.80% (95%CI: 2.18-20.15%) in elderly men. For exposure to SO2 and O3, the risk was significant in the total male population and the elderly, respectively. The results emphasize the need for further studies, focusing on modification of the effects of air pollution on health.

Environmental pollutants and stroke-related hospital admissions

“…There were 88 non-consecutive missing data entries for SO 2 (17.5 %) six missing data entries for PM 10 3 . Table 2 shows the relative risk and 95% confidence interval obtained by coefficients of Poisson regression, with the single pollutant model and the multi-pollutant model, on the same day (lag 0), with a lag of one day (lag 1) and a lag of two-days (lag 2).…”

“…Two recent national studies conducted in a medium-sized city, show the effects of exposure to pollutants from data collected from ischemic heart disease hospitalizations 2 as well as data collected from hospital mortalities, due to respiratory diseases 3 .…”

Hospital Admissions of Cardiovascular Diseases Associated to Air Pollution

“…Air pollution is associated different health outcomes and increased daily air pollution levels, especially in more susceptible population groups like children, elderly, and individuals with cardio respiratory diseases [1,2,3].In studies realized in London, was found [4] an association between PM10 and the increase in cardiovascular deaths and admissions of 2.2% (95% CI = 0.6-3.8%) and 0.6% (95% CI = 0.4-1.7%), respectively. Cities with a high degree of industrialization, including steel producing plant, intense vehicular flow and rail way transport of ores in the central region, as Volta Redonda city, in Brazil, demonstrate a significant degree of environmental vulnerability and health risk of the local population.…”

“…Others studies published on cardiovascular [1] and respiratory diseases [2,3] point out that Volta Redonda city has a high population health risk due to the atmospheric pollutants emissions. In study [1] aimed to evaluate the effects of air pollution on deaths from cardiovascular diseases, the results showed an increase risk of death for an increase of 10µg/m 3 of PM 10 at lag 2 of 3.67% (95%CI: 0.20 -7.26%) in the total population and 5.23% (95%CI: 0.85 -9.81%) for the elderly, respectively [1].…”
