背景资料：2003年10月下旬，一系列野火使南加州的城市人口在数周内暴露在空气污染水平升高的情况下。以前的研究表明，由于这些火灾，呼吸系统疾病的短期住院率特别增加。目的：我们评估了妊娠期间野火事件对足月儿出生体重的影响。研究方法：使用2001-2005年期间居住在加州南海岸空气盆地（SoCAB）的母亲分娩的单胎足月分娩记录（n = 886，034），我们比较了完全在野火事件之前或之后发生的怀孕的出生体重（n = 747，590）与那些在第一（n = 60，270），第二（n = 39，435）或第三（n = 38，739）三个月期间发生野火的人。使用固定效应回归模型估计了野火暴露对妊娠期的特定影响，其中包括几个母体特征作为协变量。结果如下：与野火前后的怀孕相比，野火发生在妊娠晚期时，平均出生体重估计低7.0 g [95%置信区间（CI）：-11.8，-2.2]，发生在妊娠中期时低9.7 g（95%CI：-14.5，-4.8），在孕早期发生时降低3.3 g（95%CI：-7.2，0.6）。结论：在2003年南加州野火期间怀孕与子宫内暴露的婴儿平均出生体重略有下降有关。野火事件的范围和频率增加可能对婴儿的健康和发育产生影响。
Background: In late October 2003, a series of wildfires exposed urban populations in Southern California to elevated levels of air pollution over several weeks. Previous research suggests that short-term hospital admissions for respiratory outcomes increased specifically as a result of these fires. Objective: We assessed the impact of a wildfire event during pregnancy on birth weight among term infants. Methods: Using records for singleton term births delivered to mothers residing in California’s South Coast Air Basin (SoCAB) during 2001–2005 (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. Results: Compared with pregnancies before and after the wildfires, mean birth weight was estimated to be 7.0 g lower [95% confidence interval (CI): –11.8, –2.2] when the wildfire occurred during the third trimester, 9.7 g lower when it occurred during the second trimester (95% CI: –14.5, –4.8), and 3.3 g lower when it occurred during the first trimester (95% CI: –7.2, 0.6). Conclusions: Pregnancy during the 2003 Southern California wildfires was associated with slightly reduced average birth weight among infants exposed in utero. The extent and increasing frequency of wildfire events may have implications for infant health and development.
