我们调查了热浪对婴儿和孕妇不利健康状况的风险，当这些母亲在怀孕期间或怀孕前暴露于热浪中时。而不仅仅是出生体重和胎龄，我们专注于不太常见的指标，如新生儿的异常状况（胎儿窘迫，呼吸机依赖和胎粪吸入）和母亲的不良健康状况（妊娠相关高血压，妊娠期间子宫出血，子痫和子宫颈功能不全）。我们使用美国3,000多个县的月度面板数据，这些数据来自1989-2008年美国出生率文件的机密版本。我们的模型控制了社会人口因素，并包括县，月和州按年的固定效应，以控制数据中未观察到的空间和时间异质性。即使在美国，那里有广泛的空调，热浪增加了与母亲压力有关的异常情况的婴儿比例，以及经历与怀孕有关的不良健康状况的母亲比例。在发展中国家，这些风险的范围可能更大。
We investigate the risks presented by heat waves for adverse health conditions for babies and expectant mothers when these mothers have been exposed to heat waves during gestation or during the period just prior to conception. Rather than just birth weight and gestational age, we focus on less common metrics such as abnormal conditions in the newborn (fetal distress, reliance on a ventilator, and meconium aspiration) and adverse health conditions in the mother (pregnancy-related hypertension, uterine bleeding during pregnancy, eclampsia, and incompetent cervix). We use monthly panel data for over 3,000 U.S. counties, constructed from the confidential version of the U.S. Natality Files for 1989-2008. Our models control for sociodemographic factors and include county, month, and state-by-year fixed effects to control for unobserved spatial and timewise heterogeneity in the data. Even within the United States, where there is widespread access to air conditioning, heat waves increase the fraction of babies with abnormal conditions related to maternal stress, as well as the fraction of mothers who experience pregnancy-related adverse health conditions. The scope for these risks in developing countries is likely to be even greater.
