摘要

背景:飓风哈维于 2017 年 8 月登陆德克萨斯州休斯敦,导致灾难性洪水。之前关于飓风和早产的研究发现了相互矛盾的结果。我们检验了飓风哈维与较高的自发早产和早产风险相关的假设,并评估了易受影响的亚人群。方法:我们利用 2015 年至 2019 年期间大休斯顿地区九个县的行政出生记录,对单胎分娩进行了回顾性研究。我们使用逻辑回归估算了早产和早产的可能性,将飓风哈维期间或飓风哈维发生后 1、2 或 4 周内的新生儿与包括前后两年相同日期的未暴露参照期进行了比较。分层模型评估了洪水程度、亲生父母年龄、高危妊娠与低危妊娠、种族/人种和产前护理对影响的修正。结果:在 15,564 名新生儿中,我们发现哈维飓风与 1 周内自发早产之间没有关联(调整后的比值比 [OR],1.06;95% 置信区间 [CI] = 0.91,1.25),但自发早产的几率要高出 14%(比值比,1.14;95% 置信区间 = 1.04,1.25)。在洪水严重的社区(OR,1.21;95% CI = 1.05,1.38)、种族隔离社区(OR,1.23;95% CI = 1.03,1.47)、外国出生的西班牙裔(OR,1.21;95% CI = 1.04,1.53)和未接受产前护理的孕妇(OR,1.37;95% CI = 1.03,1.82)中,早产几率更高。当考虑以 2 周或 4 周滞后来定义暴露时,效应估计值减弱或为零。结论哈维飓风与较高的自发早产几率有关,早产几率最高可达 1 周,尤其是在社会边缘人群中。

Hurricane Harvey and the risk of spontaneous preterm and early-term birth
Background: Hurricane Harvey made landfall in August 2017 and resulted in catastrophic flooding in Houston, Texas. Prior studies of hurricanes and preterm birth have found conflicting results. We tested the hypotheses that exposure to Hurricane Harvey was associated with a higher risk of spontaneous pre- and early-term birth and assessed vulnerable subpopulations. Methods: We conducted a retrospective study of singleton births using administrative birth records in the nine-county greater Houston area from 2015 to 2019. We estimated the likelihood of pre- and early-term births using logistic regression, comparing births occurring during or within 1, 2, or 4 weeks of Hurricane Harvey to unexposed reference periods encompassing the same dates 2 years prior and after. Stratified models assessed effect modification by degree of flooding, birth parent age, high- vs. low-risk pregnancy, race/ethnicity, and prenatal care. Results: Among 15,564 births, we found no association between exposure to Hurricane Harvey and spontaneous preterm birth within 1 week adjusted (odds ratio [OR], 1.06; 95% confidence interval [CI] = 0.91, 1.25) but a 14% higher odds of spontaneous early-term birth (OR, 1.14; 95% CI = 1.04, 1.25). The odds of early-term birth were even higher in neighborhoods with severe flooding (OR, 1.21; 95% CI = 1.05, 1.38), segregated neighborhoods (OR, 1.23; 95% CI = 1.03, 1.47), and among foreign-born Hispanics (OR, 1.21; 95% CI = 1.04, 1.53) and pregnant people receiving no prenatal care (OR, 1.37; 95% CI = 1.03, 1.82). Effect estimates were attenuated or null when considering 2-week or 4-week lags to define exposure. Conclusions: Hurricane Harvey was associated with higher odds of spontaneous early-term birth up to 1 week later, especially among socially marginalized populations.
