疟疾是一种与环境条件密切相关的传染病，因为蚊子是疾病媒介。许多研究开始记录环境条件的变化，例如森林砍伐，可以极大地改变蚊子种群的密度和活动，从而改变疟疾发病率。尽管大量流行病学研究探讨了不同地区森林丧失与蚊子扩散之间的联系，但缺乏跨多个地点的比较评估。我们试图通过对欠发达、非沙漠、疟疾流行国家进行跨国分析来解决这一差距。使用 67 个国家的结构方程模型，我们发现各国森林砍伐率与疟疾流行率之间存在正相关关系。我们的研究结果还表明，农村人口增长和农业专业化是发展中国家森林丧失的两个关键影响因素。因此，在解释疟疾发病率的跨国差异时，必须考虑环境退化的人为驱动因素。
Malaria represents an infectious disease keenly tied to environmental conditions, as mosquitoes represent the disease vector. Many studies are beginning to document that changes in environmental conditions, such as deforestation, can greatly alter the density and activity of mosquito populations and therefore malaria rates. While numerous epidemiological studies examine the links between forest loss and mosquito proliferation in distinct locales, comparative assessments across multiple sites are lacking. We attempt to address this gap by imparting a cross-national analysis of less-developed, non-desert, malaria endemic nations. Using a structural equation model of 67 nations, we find positive associations between deforestation rates and malaria prevalence across nations. Our results also suggest that rural population growth and specialization in agriculture are two key influences on forest loss in developing nations. Thus, anthropogenic drivers of environmental degradation are important to consider in explaining cross-national variation in malaria rates.
