  • outdoor air pollution and stroke in sheffield united kingdom a small area level Geographical Study
    Stroke, 2005
    Co-Authors: Ravi Maheswaran, Robert Haining, Paul Brindley, Jane Law, Tim Pearson, Peter R Fryers, Stephen Wise, Michael J Campbell
    Abstract:

    Background and Purpose— Current evidence suggests that stroke mortality and hospital admissions should be higher in areas with elevated levels of outdoor air pollution because of the combined acute and chronic exposure effects of air pollution. We examined this hypothesis using a small-area level ecological correlation Study. Methods— We used 1030 census enumeration districts as the unit of analysis and examined stroke deaths and hospital admissions from 1994 to 1998, with census denominator counts for people ≥45 years. Modeled air pollution data for particulate matter (PM10), nitrogen oxides (NOx), and carbon monoxide (CO) were interpolated to census enumeration districts. We adjusted for age, sex, socioeconomic deprivation, and smoking prevalence. Results— The analysis was based on 2979 deaths, 5122 admissions, and a population of 199 682. After adjustment for potential confounders, stroke mortality was 37% (95% CI, 19 to 57), 33% (95% CI, 14 to 56), and 26% (95% CI, 10 to 46) higher in the highest, rel...

  • stroke mortality associated with living near main roads in england and wales a Geographical Study
    Stroke, 2003
    Co-Authors: Ravi Maheswaran, Paul I P Elliott
    Abstract:

    Background and Purpose— Air pollution is associated with stroke, and road traffic is a major source of outdoor air pollution. Using proximity to roads as a proxy for exposure to road traffic pollution, we examined the hypothesis that living near main roads increases the risk of stroke mortality. Methods— We used a small-area ecological Study design based on 113 465 census enumeration districts in England and Wales. Stroke mortality ( International Classification of Disease , 9th revision, codes 430 through 438) in England and Wales from 1990 to 1992 for people ≥45 years of age was examined through the use of 1991 population denominators. Exposure was calculated as distance from each enumeration district population centroid to the nearest main road. We adjusted for age, sex, socioeconomic deprivation (using Carstairs index), regional variation, urbanization, and metropolitan area using Poisson regression. Results— The analysis was based on 189 966 stroke deaths and a population of 19 083 979. After adjustment for potential confounders, stroke mortality was 7% (95% confidence interval [CI], 4 to 9) higher in men living within 200 m of a main road compared with men living ≥1000 m away. The corresponding increase in risk for women was 4% (95% CI, 2 to 6) and the risk for men and women combined was 5% (95% CI, 4 to 7). These raised risks diminished with increasing distance from main roads. Conclusions— Living near main roads is associated with excess risk of mortality from stroke, and if causality were assumed, ≈990 stroke deaths per year would have been attributable to road traffic pollution.

  • Subterranean termites in the Centre-Val de Loire region: distribution patterns and invasion risks
    Cybergeo : Revue européenne de géographie European journal of geography, 2017
    Co-Authors: Dominique Andrieu, Elfie Perdereau, Christelle Robinet, Christelle Suppo, Simon Dupont, Maxime Cornillon
    Abstract:

    This Study presents research concerning subterranean termites found in the Centre-Val de Loire region. More specifically, we examined the Geographical distribution of Reticulitermes flavipes, a globally invasive species. This work was conducted in collaboration with both social and life science specialists in order to better understand the factors mediating its spatial distribution. Using geomatics and the spatial analysis of R. flavipes' distribution, we were able to define Geographical areas favorable to the termite. This Geographical Study and the diversity of players involved in this research underscore a growing awareness of termite invasion risks in society at large.
