Description
Summary:	Many time-series studies have shown a positive association between air pollution and asthma exacerbation. However, till now only one study in Serbia has examined this relationship. To examine the associations between air pollution and asthma emergency department (ED) visits in the Užice region, Serbia. A time-stratified case-crossover design was applied to 424 ED visits for asthma exacerbation that occurred in the Užice region, Serbia, in 2012-2014. Data about ED visits were routinely collected in the Užice Health Centre. The daily average concentrations of particulate matter (PM and PM ), sulphur dioxide (SO ), nitrogen dioxide (NO ), and black carbon (BC) were measured by automatic ambient air quality monitoring stations. Odds ratios and their corresponding 95% confidence intervals were estimated using conditional logistic regression adjusted for the potential confounding influence of weather variables (temperature, humidity and air pressure). Statistically significant associations were observed between ED visits for asthma and 3-day lagged exposure to BC (OR = 3.23; 95% CI: 1.05-9.95), and between ED visits for asthma with coexisting allergic rhinitis and 0-day lag exposure to NO (OR = 1.57; 95% CI: 0.94-2.65), 2-day lag exposure to SO (OR = 1.97; 95% CI: 1.02-3.80), and 3-day lag exposure to PM (OR = 2.38; 95% CI: 1.17-4.84). Exposure to ambient air pollution in the Užice region increases the risk of ED visits for asthma, particularly during the heating season.
