Abstract

Global climate change has transformed predictions of fire seasons in the near future, and record-breaking wildfire events have had catastrophic consequences in recent years. In September 2020, multiple wildfires subjected Oregon to hazardous air quality for several days. In this retrospective cohort study, we aimed to examine prenatal loss, morbidity, and mortality of rhesus (Macaca mulatta) and Japanese macaques (Macaca fuscata) exposed to poor air quality from the nearby wildfires. Detailed medical records from 2014 to 2020 of 580 macaques housed outdoors at a research facility in Beaverton, Oregon were used to evaluate the association between these health outcomes and wildfire smoke exposure. Logistic regression models estimated excess prenatal loss, hospitalization rates, respiratory problems, and mortality during and following the wildfire event, and Kruskal–Wallis statistics were used to determine if infant growth was affected by wildfire smoke exposure. Risk of pregnancy loss (relative risk = 4.1; p < 0.001) and odds of diagnosis with a respiratory problem (odds ratio = 4.47; p = 0.003) were higher in exposed infant macaques compared to nonexposed infants. Infant growth was not affected by poor air quality exposure. Our findings suggest wildfire smoke exposure poses a risk to the health of infants and pregnant individuals and should be monitored more closely in the future.

生活在户外并暴露于野火烟雾中的猕猴婴儿产前损失过多和呼吸道疾病。
全球气候变化改变了对近期火灾季节的预测,近年来破纪录的野火事件造成了灾难性后果。2020 年 9 月,俄勒冈州的多场野火导致空气质量连续数天处于危险状态。在这项回顾性队列研究中,我们旨在研究暴露于附近野火造成的恶劣空气质量下的猕猴(Macaca mulatta)和日本猕猴(Macaca fuscata)的产前损失、发病率和死亡率。研究人员利用俄勒冈州比弗顿一家研究机构室外饲养的 580 只猕猴在 2014 年至 2020 年期间的详细医疗记录,评估了这些健康结果与野火烟雾暴露之间的关联。逻辑回归模型估算了野火事件期间和之后的超额产前损失、住院率、呼吸系统问题和死亡率,并使用 Kruskal-Wallis 统计法确定婴儿生长是否受到野火烟雾暴露的影响。妊娠损失风险(相对风险 = 4.1; p

期刊介绍: The objective of the American Journal of Primatology is to provide a forum for the exchange of ideas and findings among primatologists and to convey our increasing understanding of this order of animals to specialists and interested readers alike. Primatology is an unusual science in that its practitioners work in a wide variety of departments and institutions, live in countries throughout the world, and carry out a vast range of research procedures. Whether we are anthropologists, psychologists, biologists, or medical researchers, whether we live in Japan, Kenya, Brazil, or the United States, whether we conduct naturalistic observations in the field or experiments in the lab, we are united in our goal of better understanding primates. Our studies of nonhuman primates are of interest to scientists in many other disciplines ranging from entomology to sociology.
