Tóm tắt

BACKGROUND: Air pollution exposure during pregnancy has been associated with adverse birth outcomes. Uncertainties remain about the effect at very low exposure levels. The aim of this study was to explore the association of maternal exposure to air pollutants during pregnancy at very low exposure levels with birth weight and estimate the health impact. METHODS: The MATEX birth cohort (226,551 singleton births in 2012-2016) was linked with eight modelled air pollutants (PM RESULTS: PM CONCLUSIONS: No clear evidence on safe exposure level was found in this study. All pollutants were associated with reduced birthweight except ozone. Causality and confounding due to correlations warrant specific attention.
