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.

“…Statistical analysis A time -series regression analysis [10][11][12] was used to examine the association between short -term fluctuations in air pollutants (PM 2.5 , PM 10 , NO 2 ) and hospital admissions for MI, using a generalized linear model and distributed lag model with the Poisson distribution. We used a previously verified generalized linear model to evaluate the relationship between air pollutants and hospital admissions, with the number of hospital admissions as the dependent variable 10-12 and the daily mean level of each individual air pollutant as the main exposure variable.…”

In Poland, the limits set by the World Health Organization (WHO) for the levels of particulate matter (PM) are far exceeded, which constitutes a major problem. The main source of PM is low-stack emission (ie, emission from residential and small-industry chimneys below the level of 40 m above ground), and to a lesser extent, transport and other sources. 2 The highest PM concentrations are observed during the heating season, especially when people use low-quality coal and INTRODUCTION Both indoor and outdoor air pollution is a serious threat to public health, as it is associated with approximately 8 million premature deaths each year. 1 There are significant regional variations in terms of the degree of air pollution as well as its chemical composition, sources of emission, and geographical location, which also affects the concentrations of pollutants and determines their effect on human health.

“…Respiratory health effects have been reported due to both short-term exposure (17,27,28) and to long-term exposure of air pollution (26,29,30). Among the air pollutants, particulate matter has received special attention as they are considered as a major component causing adverse health effects (18,22,(31)(32)(33)(34)(35)(36)(37)(38)(39). The effects of other air pollutants such as ozone (O3), nitrogen oxides (NO2, NOx), sulphur dioxide (SO2) and carbon monoxide (CO) on health have been also examined in recent studies (8,10,13,18,40,41).…”

Evaluating the effects of atmospheric environment on children’s health in Hanoi, Vietnam

Hanoi, Vietnam, has recently been facing several environmental issues including serious air pollution and climate changes, which have been reported as factors affecting child health. The purpose of my research is to evaluate the effect of atmospheric condition on children's health in Hanoi by examining how short-term changes in daily concentration of ambient air pollutants and weather condition affects the hospital admissions of children younger than 5 years old. The independent variables of the study include daily mean concentration of air pollutants such as particulate matter, nitrogen dioxide (NO2), sulphur dioxide (SO2), carbon monoxide (CO), ozone (O3) and daily meteorological data such as temperature and relative humidity, collected from the national automatic air quality stations. The dependent variables are the daily hospital admissions in children aged less than 5 and were collected from three hospitals in Hanoi. My thesis includes eight chapters which are Introduction (Chapter 1), Methods (Chapter 3), and four studies presented respectively in chapters 2, 4, 5 and 6; a Discussion (Chapter 7) and References (Chapter 8). My first study is a systematic review and meta-analysis on the relationship between air pollution and risk for a specific group of respiratory diseases: wheeze-associated disorders among children in Southeast Asia area. I searched the relevant computerized databases (PubMed, EMBASE, Web of Science, Scopus, and Cochrane library) for indexed publications up to July 2018. Finally, eight studies were qualified for performing a randomeffect meta-analysis to compute the pooled effect sizes. The results show that each increase of 10 µg/m 3 in concentrations of PM2.5 or PM1 was associated with 1-2% increase in risk of wheeze-associated disorders. Positive associations were found for PM10, SO2, NO2, NOx but no association was found for CO and O3. My study confirmed the strong effect of fine particulate matters on respiratory health and I recommend an updated meta-analysis should be done when more studies are available. A manuscript based on the results from this study has been published in Reviews on Environmental Health in the early of 2019 (Chapter 2). My second study examined the relationship between particulate air pollution and hospital admissions for respiratory diseases by using the time-stratified case-crossover design. The results confirmed that the daily hospital admissions for respiratory diseases among children
