This article uses nineteenth-century evidence to calculate the impact of early exposure to malaria-ridden environments on nutritional status and the immune system in America. I estimate the risk of contracting malarial fevers in the 1850s by using correlations between malaria and environmental factors such as climate and geographical features. The study demonstrates that Union Army recruits who spent their early years in malaria-endemic counties were 1.1 inches shorter at enlistment due to malnutrition and were 13 percent more susceptible to infections during the U.S. Civil War as a result of immune disorders than were those from malaria-free regions.
本文利用19世纪的证据来计算早年暴露于疟疾肆虐环境对美国营养状况和免疫系统的影响。我通过利用疟疾与气候和地理特征等环境因素之间的相关性来估计19世纪50年代感染疟疾热的风险。该研究表明,在内战前早年生活在疟疾流行县的联邦军队新兵,由于营养不良,入伍时身高矮1.1英寸,并且由于免疫紊乱,在内战期间比来自无疟疾地区的新兵更容易感染,感染几率高出13%。
