TAILIEUCHUNG - Exposures to fine particulate air pollution and respiratory outcomes in adults using two national datasets: a cross-sectional study

The French work was based on the available Black Smoke (BS) data. A correlation analysis between BS and PM10 (TEOM method7 ) was first carried out. It was found that at urban background sites, BS and PM10 (TEOM) are about equal. Following this, linear relationships were sought between the BS data and land use categories in the areas surrounding the measurement sites. Multiple regression analysis was performed for three categories of sites: urban, suburban and rural. Based on these regressions and using the land use data set, a PM10 map was established. A correction factor for secondary particles was defined using the European scale EMEP8 model.

Recent data from nationally representative surveys suggest increasing disparity by race ethnicity regarding asthma-related morbidity and mortality. The objectives of this study are to evaluate the relationship between annual average ambient fine particulate matter concentrations and respiratory outcomes for adults using modeled air pollution and health outcome data and to examine sensitivity across race ethnicity. Methods Respondents from the 2002-2005 National Health Interview Survey NHIS were linked to annual kriged data from the USEPA AirData system. Logistic regression was employed to investigate increases in ambient concentrations and self-reported prevalence of respiratory outcomes including asthma sinusitis and chronic bronchitis. Models included health behavioral demographic and resource-related covariates. Stratified analyses were conducted by race ethnicity. Results Of nearly 110 000 adult respondents approximately 8 000 and 4 000 reported current asthma and recent attacks respectively. Overall odds ratios OR for current asthma 95 Confidence Interval and recent attacks did not suggest an association with a 10 pg m3 increase in PM2 5. Stratified analyses revealed significant associations for non-Hispanic blacks OR for current asthma and OR for recent attacks but not for Hispanics and non-Hispanic whites. Significant associations were observed overall and in non-Hispanic whites for sinusitis but
