Urban Air and Emergency Department Visits in Toronto, Canada
This study examines the relationship between short-term exposure to ambient air pollution and the onset of human health conditions in Toronto, Canada. Urban air quality is influenced by various pollutants, many of which pose risks to human health. This research specifically investigates the acute effects of these pollutants in Toronto, with health outcomes measured by emergency department visits. To assess relative risks, statistical models were …
Urban Air Pollution and Emergency Department Visits for Neoplasms and Outcomes of Blood Forming and Metabolic Systems
This study focused on investigating possible associations between exposure to urban air pollution and the number of emergency department (ED) visits for various health outcomes. The outcomes were grouped into four chapters of the International Classification of Diseases Tenth Revision (ICD-10) system (i.e., Chapter II-IV: "Neoplasms", "Diseases of the blood", "Endocrine, nutritional and metabolic diseases", and XVIII: "Symptoms, signs and abnorma…
Concentration–Response Functions as an Essence of the Results from Lags
Among various aspects of environmental epidemiology, one is to assess the relationships between ambient air pollution and health outcomes. The goal of this work is to estimate the associations in the form of the parametric concentration-response functions (C-RF). Various forms of the C-RFs are proposed in this short-term health effect study. Emergency department (ED) visits for all respiratory health problems are analyzed as an illustrative examp…
Air Pollution and Emergency Department Visits for Mental Disorders among Youth
Although exposure to ambient air pollution has been linked to mental health problems, little is known about its potential effects on youth. This study investigates the association between short-term exposure to air pollutants and emergency department (ED) visits for mental health disorders. The National Ambulatory Care Reporting System database was used to retrieve ED visits for young individuals aged 8-24 years in Toronto, Canada. Daily average …
Case-Crossover Method with a Short Time-Window
Numerous epidemiological studies have shown associations between short-term ambient air pollution exposure and various health problems. The time-stratified case-crossover design is a popular technique for estimating these associations. In the standard approach, the case-crossover model is realized by using a conditional logistic regression on data that are interpreted as a set of cases (i.e., individual health events) and controls. In statistical…
Global estimates of mortality associated with long-term exposure to outdoor fine particulate matter
Exposure to ambient fine particulate matter (PM 2.5 ) is a major global health concern. Quantitative estimates of attributable mortality are based on disease-specific hazard ratio models that incorporate risk information from multiple PM 2.5 sources (outdoor and indoor air pollution from use of solid fuels and secondhand and active smoking), requiring assumptions about equivalent exposure and toxicity. We relax these contentious assumptions by co…
Health benefits of reducing NO x emissions in the presence of epidemiological and atmospheric nonlinearities
Recent epidemiological evidence suggests that the logarithm of concentration is a better predictor of mortality risk from long-term exposure to ambient PM2.5 and NO2 than concentration itself. A log-concentration-response function (CRF) predicts a heightened excess risk per unit concentration at low levels of exposure that further increases as the air becomes less polluted. Using an adjoint air quality model, we estimate the public health benefit…
Emergency department visits for asthma in relation to the Air Quality Health Index
Ambient Ozone and Emergency Department Visits for Cellulitis
Objectives were to assess and estimate an association between exposure to ground-level ozone and emergency department (ED) visits for cellulitis. All ED visits for cellulitis in Edmonton, Canada, in the period April 1992-March 2002 (N = 69,547) were examined. Case-crossover design was applied to estimate odds ratio (OR, and 95% confidence interval) per one interquartile range (IQR) increase in ozone concentration (IQR = 14.0 ppb). Delay of ED vis…
