Previous research suggests that short-term hospital admissions for respiratory outcomes increased specifically as a result of these fires.<\/jats:p>\n                  <jats:p>Objective: We assessed the impact of a wildfire event during pregnancy on birth weight among term infants.<\/jats:p>\n                  <jats:p>Methods: Using records for singleton term births delivered to mothers residing in California\u2019s South Coast Air Basin (SoCAB) during 2001\u20132005 (n = 886,034), we compared birth weights from pregnancies that took place entirely before or after the wildfire event (n = 747,590) with those where wildfires occurred during the first (n = 60,270), second (n = 39,435), or third (n = 38,739) trimester. The trimester-specific effects of wildfire exposure were estimated using a fixed-effects regression model with several maternal characteristics included as covariates.<\/jats:p>\n                  <jats:p>Results: Compared with pregnancies before and after the wildfires, mean birth weight was estimated to be 7.0 g lower [95% confidence interval (CI): \u201311.8, \u20132.2] when the wildfire occurred during the third trimester, 9.7 g lower when it occurred during the second trimester (95% CI: \u201314.5, \u20134.8), and 3.3 g lower when it occurred during the first trimester (95% CI: \u20137.2, 0.6).<\/jats:p>\n                  <jats:p>Conclusions: Pregnancy during the 2003 Southern California wildfires was associated with slightly reduced average birth weight among infants exposed in utero.
