“…PM 2.5 environmental pollution, in particular black carbon (a traffic-related PM 2.5 constituent), from proximity to major roadways has been associated with lower lung function in the Boston, USA, area (29). Moreover, from a study conducted at a day-care center in northeastern Seoul, Korea, indoor air pollutants resulting from nearby heavy traffic and a metro station increased the risk of allergy in children (aged 4.4±1.2 years).…”

Indoor/outdoor not-voluptuary-habit pollution and sleep-disordered breathing in children: a systematic review

Background: Exposure to environmental pollutants is advocated to be a major risk factor, with increased morbidity and mortality in humans due to acute and chronic airway inflammation. The aim of the present review is to show the literature research regarding the link between the sleep-disordered breathing and exposure to indoor/outdoor pollution in children. We hypothesized that environmental air pollution can play a role in childhood sleep-disordered breathing. Methods:We conducted an electronic search in Medline (with PubMed interface), Scopus and the ISI Web of Science using the keywords "sleep" or "sleep apnea" or "sleep disordered breathing" and "pollution" and "children" in "Title/Abstract/Keywords", with language restriction (non-English paper) and no date limitation to present. The tobacco smoke pollution is well established linking and is not considered for the present subject. We examined the strength of the evidence according to the Oxford Centre for Evidence- Results: A total of 105 articles were identified, but 97 of these had to be excluded after an accurate reading of the title, abstract or full text. In the end, eight studies were selected for our analysis for a total of a total of 5,826 children. The results suggest an involvement (grade C) of environmental (not from voluptuary habits) pollution in the worsening of sleep-disordered breathing in children.Conclusions: To date, some studies reported significant differences between areas with higher and lower pollutants and the interventions on indoor pollution reduced sleep-disordered breathing in children.Therefore, although the relevance of the argument is high, the number of studies and the interest in the subject seems at this time quite limited.

Adolescent lung function associated with incense burning and other environmental exposures at home

Incense burning is a popular cultural and religious practice, but whether exposure to incense smoke has effects on lung function is unclear. We investigated association between lung function and incense burning exposure and other household exposures in adolescents who participated in a mass asthma‐screening program. Information on asthmatic status and associated factors was obtained from parent‐completed questionnaires and student‐completed video questionnaires. Approximately 10% of students received lung function examinations. Valid lung function data of 5010 students aged 14‐16 years in northern Taiwan were analyzed. Forced vital capacity (FVC) and forced expiratory flow in 1 second (FEV 1) were compared by incense burning status and other types of exposures for adolescents. Overall, 70.6% of students were exposed to incense smoke at home. The mean FVC and FEV 1 measures were lower among adolescents with daily exposure to incense burning than those without such exposure (P<.05). Sharing bedroom was also associated with decreased FVC and FEV 1. After controlling for confounding factors, multivariable linear regression analysis with generalized estimation equation showed that FVC was negatively associated with daily exposure to incense burning, sharing a bedroom, and living in a house adjacent to a traffic road. Such associations were also observed in FEV 1. Daily exposure to incense burning is associated with impaired adolescent lung function.

“…We should note that epidemiologic studies to date, including this one, have not measured lung volumes, so any conclusions regarding lung "growth" are speculative. Here, Rice and colleagues postulate that the pattern of lung impairment they observed could be consistent either with restricted growth or with a pattern of small airway obstruction that results in proportional decline in forced expiratory volumes (13). This later hypothesis might be more in keeping with pollution's known effects of airway inflammation and radiographic evidence of lung hyperinflation and air trapping in exposed children (14).…”

“…881-888) present an analysis within a well-designed prospective cohort to assess whether long-term ambient air pollution adversely affects lung function, even after policy changes that resulted in improvements in air quality (13). In contrast to other studies, the authors were able to characterize the cohort and potential confounders from birth, they used advanced modeling of exposures to air pollution within a city and over time, and they used robust measurements of lung function by including both pre-and post-bronchodilator spirometry.…”

“…The findings of Rice and colleagues provide compelling additional evidence that it is timely to reevaluate the effects of lower levels of air pollutants on human health (13). Although carefully conducted, there are limitations to the work that should be noted, in addition to the usual caveats regarding observational rather than experimental designs and the risk for residual confounding.…”
