Abstract: Background: Low birth weight has been associated with many negative health outcomes which pose a burden on the infant, the family of the infant, and the healthcare system. Identifying possible exposures and risk factors is a crucial step in helping to establish preventative measures. Objective: The objective of this literature review was to determine if there is an association between prenatal exposure to air pollution and decreased birth weight (DBW) and/or low birth weight (LBW). Methods: This literature review utilized several online databases to collect research articles. After applying exclusion criteria and removing duplicates, only 30 articles were reviewed. Results: A majority of the 30 articles reviewed supported the positive relationship of prenatal exposure to air pollution with LBW and DBW. The most common pollutants shown to have a positive association to both LBW and DBW across multiple studies include PM2.5, PM10, CO, SO2 and NO2. Furthermore, other articles found an insignificant relationship or no relationship between prenatal exposure to air pollution and LBW or DBW. Conclusion: There is a general consensus in the literature that prenatal exposure to air pollution is associated with both LBW and DBW. This is a finding that should fuel future interventions and policy development.
