“…26 Also, a study by Bouazza et al, on children, in Paris, showed that there was a significant relation between exposure to air pollution especially particulate matter (PM) and exacerbations of asthma symptoms in children visiting the emergency department. 27 Another study by Salimi et al, about long-term exposure to air pollution and hospitalization for respiratory diseases in Australia, showed that there was a weak but direct relation between exposure to air pollution and hospitalization for asthma. 28 According to the American College of Lung Physicians (CHEST) report in 2018, 65 million people suffer from chronic obstructive pulmonary disease (COPD) and 3 million die each year, making it the third leading cause of death worldwide.…”

Background and Aim: Although air pollution is a serious problem in Ahvaz, the association between air pollution and respiratory diseases has not been studied enough in this area. The aim of this study was to determine the relation between short-term exposure to air pollutants and the risk of hospital admissions due to asthma, COPD, and bronchiectasis in Ahvaz. Methods: Hospital admissions data and air pollutants including O 3 , NO, NO 2 , SO 2 , CO, PM 10, and PM 2.5 were obtained from 2008 to 2018. Adjusted Quasi-Poisson regression with a distributed lag model, controlled for trend, seasonality, weather, weekdays, and holidays was used for data analysis. Results: The results showed a significant increase in hospital admissions for asthma (RR=1.004, 95% CI: 1.002-1.007) and COPD (RR=1.003, 95% CI: 1.001-1.005) associated with PM 2.5 . PM 10 was associated with increased hospital admissions due to bronchiectasis in both genders (Men: RR=1.003, 95% CI: 1.001-1.006) (Female: RR=1.003, 95% CI: 1.000-1.006). NO 2 was also associated with an increased risk of hospital admissions for asthma (RR=1.040, 95% CI: 1.008-1.074) and COPD (RR=1.049, 95% CI: 1.010-1.090). SO 2 was associated with the risk of hospital admissions of asthma (RR=1.069, 95% CI: 1.017-1.124) and bronchiectasis (RR=1.030, 95% CI: 1.005-1.056). Finally, CO was associated with COPD (RR=1.643, 95% CI: 1.233-2.191) and bronchiectasis (RR=1.542, 95% CI: 1.035-2.298) hospital admissions. Conclusion: Short-term exposure to air pollutants significantly increases the risk of hospital admissions for asthma, COPD, and bronchiectasis in the adult and elderly population.

“…Bouazza et al 3 did not detect additional effects of O 3 or NO 2 on asthma ED visits after accounting for PM 2.5 , which suggests that fine particles could be the trigger of asthma exacerbations on days of relatively high air pollution. However, PM 2.5 and NO 2 correlated strongly and could be surrogates of traffic-related pollution in urban areas.…”

“…In a large longitudinal study presented in this journal, Bouazza et al 3 examined paediatric visits for asthma exacerbation to emergency departments (EDs) in Paris, France, in relation to air pollution and other factors such as daily weather (including temperature and humidity), viral infections and pollen data. The authors analysed over 47 000 cases of paediatric visits in 20 hospitals over 5 years using a non-linear modelling approach to examine the exposure–response relationship between single or multiple pollutants and asthma exacerbations.…”

“…Bouazza et al 3 examined pollen as a single entity, although it consists of many species which have different levels of allergenicity and size, altering its role in asthma exacerbations. Additional work examining pollen at the species level may provide more refined results.…”

“…Bouazza et al 3 used pollution data from the air quality monitoring network in the region of Paris. The study included a limited number of monitoring stations, particularly for PM 2.5 , for which data from only four locations (one very near and three outside Boulevard Périphérique, the ring road of Paris) were obtained.…”

Issued addressed: There is increasing evidence that exposure to traffic-related air pollution is related to childhood respiratory symptoms. This study demonstrated the effectiveness of an anti-idling behavioural intervention targeting parents at primary schools.Methods: Based on two focus group discussions with parents, a low-intensity 4-week anti-idling intervention was developed, comprising onsite signage, four newsletters, and two fact sheets. Exposure to selected air pollutants was assessed during pick-up and drop-off times pre-and postintervention at 12 randomly selected independent schools (10 intervention and 2 control) across the Perth metropolitan area. Results:The study results showed that a low-intensity behavioural intervention can be an effective strategy to affect parents' attitude towards vehicle idling. This was demonstrated by the reduced number of idling vehicles observed in 8 of the 10 intervention schools and decreased overall particulate matter concentration after the anti-idling intervention. Conclusion:Anti-idling education can be effective in promoting clean travel behaviours and has potential health benefits for school children. So what?This intervention study provides insights on the significant effect of antiidling education on parents' behaviour towards air quality and children's health. These promising findings warrant further rigorous actions on anti-idling education and enforcement.
