“…Atopy, which is an abnormal production of E immunoglobulin as a response to surrounding allergens, is the strongest predisposing factor for developing asthma. Asthma exacerbation [93,94], severe respiratory symptoms [84,108], acute lower respiratory tract infections [103] and moderate airway obstruction on spirometry [109] were also observed in children due to various sources of indoor pollution (e.g., smoking, stoves, allergens, etc.) in households [87] and schools [106].…”

Exposure to airborne fine particulate matter (PM 2.5) carries substantial health risks, particularly for younger children (0-10 years). Epidemiological evidence indicates that children are more susceptible to PM health effects than adults. We conducted a literature review to obtain an overview of existing knowledge regarding the correlation of exposure to short-and long-term PM concentrations with respiratory symptoms and disease in children. A collection of scientific papers and topical reviews were selected in cooperation with two experienced paediatricians. The literature review was performed using the keywords "air pollution", "particulate matter", "children's health" and "respiratory" from 1950 to 2016, searching the databases of Scopus, Google Scholar, Web of Science, and PubMed. The search provided 45,191 studies for consideration. Following the application of eligibility criteria and experts' best judgment to titles and abstracts, 28 independent studies were deemed relevant for further detailed review and knowledge extraction. The results showed that most studies focused mainly on the effect of short-term exposure in children, and the reported associations were relatively homogeneous amongst the studies. Most of the respiratory diseases observed in outdoor studies were related to changes in lung function and exacerbation of asthma symptoms. Allergic reactions were frequently reported in indoor studies. Asthma exacerbation, severe respiratory symptoms and moderate airway obstruction on spirometry were also observed in children due to various sources of indoor pollution in households and schools. Mixed indoor and outdoor studies indicate frequent occurrence of wheezing and deterioration of lung function. There is good evidence of the adverse effect of short-term exposure to PM on children's respiratory health. In terms of long-term exposure, fine particles (PM 0.1-PM 2.5) represent a higher risk factor than coarse particles (PM 2.5-PM 10). Additional research is required to better understand the heterogeneous sources and the association of PM and adverse children's health outcomes. We recommend long-term cooperation between air quality specialists, paediatricians, epidemiologists, and parents in order to improve the knowledge of PM effects on young children's respiratory health.

“…Our results in Chile were consistent with several observational studies conducted in low‐ and middle‐income countries with higher prevalence of biomass fuel use. However, previously published studies have found an association between the exposure to solid fuel smoke and the occurrence of LRTI in children younger than 5 years of age and adverse pregnancy outcomes (Amegah et al., ; Lakshmi et al., ; Mahalanabis et al., ; Ramesh Bhat et al., ; Tielsch et al., ).…”

Objective To evaluate the association between household air pollution (HAP) with lower respiratory tract infection (LRTI) in children younger than 5 years old and adverse pregnancy outcomes. Study Design and Setting This retrospective cohort study took place in two cities in Patagonia. Using systemic random sampling, we selected households in which at least one child <5 years had lived and/or a child had been born alive or stillborn. Trained interviewers administered the questionnaire. Results We included 926 households with 695 pregnancies and 1,074 children. Household cooking was conducted indoors in ventilated rooms and the use of wood as the principal fuel for cooking was lower in Temuco (13% vs 17%). In exposed to biomass fuel use, the adjusted OR for LRTI was 1.87 (95% CI 0.98-3.55; p = 0.056) in Temuco and 1.12 (95% CI 0.61-2.05; p = 0.716) in Bariloche. For perinatal morbidity, the OR was 3.11 (95% CI 0.86-11.32; p = 0.084) and 1.41 (95% CI 0.50-3.97; p = 0.518), respectively. However, none of the effects were statistically significant (p >0.05) Conclusion The use of biomass fuel to cook in traditional cookstoves in ventilated dwellings may increase the risk of perinatal morbidity and LRTI.

“…Other than that, this review paper did not attempt to identify intervention studies. IAP is a crucial risk factor for acute lower respiratory tract infections (ALRTI) in developing countries (19). Recent international data indicate that, currently, the increase of asthma and allergies in children is most pronounced in the more advanced developing countries (20).…”

AbstractThe indoor environment is a major source of human exposure to pollutants. Some pollutants can have concentrations that are several times higher indoors than outdoors. Prolonged exposure may lead to adverse biologic effects, even at low concentrations. Several studies done in Malaysia had underlined the role of indoor air pollution in affecting respiratory health, especially for school-aged children. A critical review was conducted on the quantitative literature linking indoor air pollution with respiratory illnesses among school-aged children. This paper reviews evidence of the association between indoor air quality (IAQ) and its implications on respiratory health among Malaysian school-aged children. This review summarizes six relevant studies conducted in Malaysia for the past 10 years. Previous epidemiologic studies relevant to indoor air pollutants and their implications on school-aged children’s respiratory health were obtained from electronic database and included as a reference in this review. The existing reviewed data emphasize the impact of IAQ parameters, namely, indoor temperature, ventilation rates, indoor concentration of carbon dioxide (CO
