Abstract
Purpose. To examine the role of air quality in relation to chronic bronchitis, emphysema, asthma, wheeze, and dry cough among adolescents from the United Arab Emirates (UAE). Methods. A survey was administered on 6,363 adolescents from 9 UAE regions. Data consists of demographic, socioeconomic, residential, and behavioural variables, such as location of residence, residing near industry/gas stations/dumpsites/construction sites, residing near overhead power line/plants, exposure to tobacco, residential exposure, ethnicity, concern over air pollution, smoking, and purposely smelling gasoline fumes/glue/correctors/car exhaust/burning black ants. Logistic regression modeling was used to determine significant predictors of respiratory health. Results. Asthma prevalence was 12.3%, followed by chronic bronchitis (1.8%) and emphysema (0.5%). Overall 12.2% reported wheeze and 34.8% reported a dry nocturnal cough in the past year. Multivariate analyses suggest that sex is a significant predictor of asthma and dry cough. Exposure to tobacco and arts/crafts/ceramics/stain is significant predictor of respiratory health. Tobacco smoking and purposely smelling gasoline fumes/glue/correctors/car exhaust/burning black ants are significant predictors of wheeze and dry cough. Conclusions. This study suggests that exposure to air quality and behavioral factors such as smoking and purposely smelling gasoline fumes, glue, correctors, car exhaust, or burning black ants are significant predictors of respiratory health among UAE adolescents.

Summary
The World Health Organization identified indoor and outdoor air pollution as the “world’s largest single environmental health risk” [1]. Major preventable chronic respiratory conditions are chronic obstructive pulmonary disease (COPD), asthma, and occupational lung diseases [5]. COPD is generally characterized by the presence of chronic bronchitis or emphysema that can lead to airway obstruction [6]. Subcutaneous emphysema and chronic bronchitis can result from repeated infections or injury in childhood or early adulthood [8,9,10], asthma is the most prevalent chronic respiratory condition of childhood [11]. Respiratory symptoms are generally used to suggest the presence of acute or chronic respiratory conditions. Dry cough can be a symptom of many conditions as well, such as asthma, COPD, pulmonary fibrosis, and rhinosinusitis [13]. In regions where diagnoses with respiratory conditions are underestimated, respiratory symptoms can serve as possible proxies
