Abstract Title:
Ambient air pollution and markers of fetal growth: A retrospective population-based cohort study of 2.57 million term singleton births in China.
Abstract:
BACKGROUNDS: Evidence is scarce on the relation between maternal exposure to ambient air pollution during pregnancy and fetal growth in developing countries. Moreover, the current evidence is inconsistent. We aimed to investigate the association of trimester-specific exposure to air pollution with risk of being born small for gestational age (SGA) and birth weight-markers of fetal growth-among Chinese term births.METHODS: This retrospective population-based cohort study consisted of 2,567,457 singleton term live-births from January 1, 2014 to December 31, 2017 across 123 Chinese districts and counties. Personal exposure to ambient air pollutants including carbon monoxide (CO), sulfur dioxide (SO), nitrogen dioxide (NO), ozone (O), particulate matter with aerodynamic diameter
