Association between ambient air pollution exposure and infants small for gestational age in Huangshi, China: a cross-sectional study

Abstract: Small for gestational age (SGA) is defined as intrauterine growth retardation or small sample, referring to the 10th percentile of birth weight lower or two standard deviations less than the average weight at the same gestational age. SGA infants bring great economic and psychological burdens to families and society. The association between exposure to air pollution and SGA in underdeveloped cities with poor air quality remains unclear. Thus, this study is conducted to estimate the effects of maternal exposure… Show more

“…Long-term exposure to PM2.5 (i.e. PM ≤ 2.5 microns in aerodynamic diameter) can lead to small gestational age (Hao et al, 2019), respiratory disease (Li et al, 2013a(Li et al, , 2013bConibear et al, 2018;Slama et al, 2019), ischemic heart disease (Pope et al, 2015;Thurston et al, 2016;Shah et al, 2013), and a range of lung diseases (Chow, 2006;Araujo et al, 2011), especially in residential areas that burn large amounts of fossil fuels. Even in the case of low mass concentrations of airborne particles, pollutants still can increase exposure risk (Kim et al, 2015).…”

“…This could potentially lead to seasonality bias. Moreover, as suggested by Hao et al and by Raz et al, we cannot exclude a selection bias called live-birth bias at the beginning of the pregnancy due to early abortions that can be caused by exposure to air pollution because they were not detectable in our study and therefore were not included 68,69 Compared to the single pregnancies recorded in the 2010 French perinatal study, our study sample presented just slightly adverse outcomes 70 . In fact, the two maternities included are level 3 maternity units where complicated pregnancies are more closely monitored.…”

“…Removing a particular study did not affect the pooled estimates by more than 3% (data not shown), and the significance of the associations did not change except in a few instances. That is, the observed association between SGA and PM 2.5 exposure during the first trimester became statistically significant when either Percy et al ( 2019 ) or Hao et al ( 2019 ) was removed; on the other hand, an association for SGA and PM 2.5 exposure during the third trimester was no longer significant after either Liu et al ( 2007 ), Hyder et al ( 2014 ), or Hao et al ( 2019 ) was removed. Nonetheless, there was no significant publication bias for all exposures and outcomes except for the association between SGA (continuous) PM 2.5 exposure during the third trimester (Egger’s test p < 0.05).…”
