Abstract

Background: Not many studies have investigated the relationship between maternal exposure to ambient particulate matter, especially matter with an aerodynamic diameter of less than 10 μm (PM10) during pregnancy, and the rate of low birth weight. Limited studies have been conducted in broad national areas for over many years. Method: Data on birth weight and air pollution from 2007 to 2020 in the US counties is collected, including 628 counties. Logarithmic transformed LAD regression was used to examine the association between air pollutants, especially PM10, and birth weight. Results: PM10 demonstrated a negative impact on the term LBW and most birth weight categories. A trend was observed: as birth weight categories increase, the magnitude of the PM10 estimate decreases as birth weight approaches the normal range, from 0.0064 to 0.0008. After examining the associations between birth weight categories and the term LBW, a negative association between PM10 level and birth weight is found for LBW categories. Conclusion: The impact of PM10 on regular-weighted babies is less significant than on low-weighted babies, and an increased risk of low birth weight with increasing PM10 levels was not found.
