在自然灾害和人为灾害之后，人口出生结果的变化，包括低出生体重或早产的增加，都有记录。然而，在2011年福岛第一核电站灾难之后，信息是有限的。在这项研究中，我们评估了灾后出生结果与灾前数据相比是否存在长期变化，以及作为疏散和辐射相关焦虑的代理测量的住宅面积和食品购买模式是否与灾后出生结果相关。回顾性收集了2008年至2015年在距离电厂23公里的一家公立医院所有活产单胎的孕产妇和围产期数据。比较了灾前和灾后低出生体重（出生时<2500克）和早产（出生时妊娠<37周）的比例，并建立了回归模型来评估这些结果与疏散和食物避免之间的关系。统计共包括1101名活产单胎婴儿。灾后任何年份低出生体重儿或早产的比例均未增加(低出生体重儿合并灾后风险比：0.98,95%可信区间（CI）： 0.64-1.51；早产：0.68,95% CI: 0.38-1.21)。在协变量调整后，没有发现出生结果与居住区域或食品购买模式之间的显著关联。总之，在福岛灾难发生后，这项基于机构的调查没有发现出生结果的变化。需要进一步研究可能加剧或减少灾害对孕产妇和围产期健康影响的途径。
Changes in population birth outcomes, including increases in low birthweight or preterm births, have been documented after natural and manmade disasters. However, information is limited following the 2011 Fukushima Daiichi Nuclear Power Plant Disaster. In this study, we assessed whether there were long-term changes in birth outcomes post-disaster, compared to pre-disaster data, and whether residential area and food purchasing patterns, as proxy measurements of evacuation and radiation-related anxiety, were associated with post-disaster birth outcomes. Maternal and perinatal data were retrospectively collected for all live singleton births at a public hospital, located 23 km from the power plant, from 2008 to 2015. Proportions of low birthweight (<2500 g at birth) and preterm births (<37 weeks gestation at birth) were compared pre- and post-disaster, and regression models were conducted to assess for associations between these outcomes and evacuation and food avoidance. A total of 1101 live singleton births were included. There were no increased proportions of low birthweight or preterm births in any year after the disaster (merged post-disaster risk ratio of low birthweight birth: 0.98, 95% confidence interval (CI): 0.64–1.51; and preterm birth: 0.68, 95% CI: 0.38–1.21). No significant associations between birth outcomes and residential area or food purchasing patterns were identified, after adjustment for covariates. In conclusion, no changes in birth outcomes were found in this institution-based investigation after the Fukushima disaster. Further research is needed on the pathways that may exacerbate or reduce disaster effects on maternal and perinatal health.
