论文摘要
这项研究使用了日本1918 - 1920年流感大流行的数据以及新近数字化和完整的人口普查记录,以分析子宫内的死亡率选择。我发现胎儿在怀孕的头三个月中暴露于流感大流行会减少出生时男性的比例。机制分析的结果表明,男性出生的这种下降与胎儿和婴儿健康的恶化有关。该结果支持有关大流行性流感的长期不良影响的广泛现有文献。
This study uses data from the 1918-1920 influenza pandemic in Japan along with newly digitized and complete census records on births and infant deaths to analyze mortality selection in utero. I find that fetal exposure to the influenza pandemic during the first trimester of the pregnancy decreases the proportion of males at birth. The results from mechanism analysis suggest that this decline in male births is associated with the deterioration of fetal and infant health. This result supports a wide range of existing literature on the long-run adverse effects of pandemic influenza.
