Considered a part of the behavioral immune system (BIS), disgust sensitivity is expected to be adjusting as a response to the actual level of the environmental health risks.
In this preregistered study, we tested the hypothesis that disgust sensitivity would be higher during the COVID-19 pandemic compared to the pre-pandemic period in pregnant women. In this between-subject study with a longitudinal trend design, we administered the Disgust Scale-Revised to 200 pregnant women before the pandemic and to 350 pregnant women during the pandemic.
We found a small but significant effect of the pandemic on disgust sensitivity, such that higher disgust sensitivity was found in women pregnant during the pandemic. This effect was stronger in primiparae, however, the interaction between parity and the pandemic period was not significant. Disgust sensitivity decreased with age. No differences in terms of nausea and vomiting were found between the women pregnant before and during the pandemic.
Our findings indicate that although BIS is presumed to function as a complex mechanism to prevent health-threatening behaviors, its activation in pregnant women during the COVID-19 pandemic is rather weak.
厌恶敏感性被认为是行为免疫系统（BIS）的一部分，预计会随着对环境健康风险实际水平的反应而进行调整。
在这项预先注册的研究中，我们检验了这样一个假设：与大流行前时期相比，孕妇在新冠疫情期间的厌恶敏感性会更高。在这项采用纵向趋势设计的组间研究中，我们在大流行前对200名孕妇以及在大流行期间对350名孕妇施测了修订后的厌恶量表。
我们发现大流行对厌恶敏感性有微小但显著的影响，即在大流行期间怀孕的女性中发现了更高的厌恶敏感性。这种影响在初产妇中更强，然而，产次与大流行时期之间的交互作用并不显著。厌恶敏感性随年龄增长而降低。在大流行前和大流行期间怀孕的女性之间，在恶心和呕吐方面未发现差异。
我们的研究结果表明，尽管行为免疫系统被假定为一种预防健康威胁行为的复杂机制，但其在新冠疫情期间孕妇中的激活相当微弱。
