Review Meta AnalysisThe impact of prenatal exposure to air pollution on childhood wheezing and asthma: A systematic review.
There has been no clear consensus about whether prenatal exposure to air pollution contributes to the development of wheezing and asthma in children. We conducted a systematic review to analyze the association between exposure to different pollutants during pregnancy and the development of childhood wheezing and asthma. ⋯ The overall and subgroup risk estimates from the meta-analyses showed statistically significant associations between prenatal exposures to NO2, SO2, and PM10 and the risk of wheezing and asthma development in childhood. There is insufficient evidence to show an effect of prenatal exposure to BC, CO, and O3 on childhood wheezing and asthma. Further studies are needed to examine the individual compounds' effects.

Review Meta AnalysisShort-term exposure to air pollution and morbidity of COPD and asthma in East Asian area: A systematic review and meta-analysis.
The association between short-term exposure to air pollution and morbidity of COPD and asthma has been observed in many studies. However, there is a lack of systematic review of the overall risk ratios in East Asian area to provide scientific evidence for health risk assessment. ⋯ Evidence was found that short-term exposure to air pollution was associated with increasing risk of hospital utilization for COPD and asthma in the whole population, the elderly and children, but not in people aged 15-64. Children tended to be more susceptible to the effect of air pollution on asthma morbidity.

Review Meta AnalysisSystematic review and meta-analysis of the adverse health effects of ambient PM2.5 and PM10 pollution in the Chinese population.
As the largest developing country, China has some of the worst air quality in the world. Heavy smog in January 2013 led to unprecedented public concern about the health impact of exposure to particulate matter. Conducting health impact assessments of particulate matter has thus become an urgent task for public health practitioners. Combined estimates of the health effects of exposure to particulate matter from quantitative reviews could provide vital information for epidemiology-based health impact assessments, but estimates for the Chinese population are limited. ⋯ Short exposures to PM10 and PM2.5 are associated with increases in mortality, but evidence of constituent-associated health effects, long-term effects and morbidity in China is still inadequate.
