This paper analyzes factors affecting the risk of malaria among individuals working in wildcat gold mining camps (garimpos) in northern Mato Grosso State in the Brazilian Amazon. Historically, such mining camps have the locations with the highest malaria prevalence in the Brazilian Amazon. However, little attention has focused on understanding the disease from the internal perspective of the mining camps themselves, such as the mining population's characteristics and its spatial organization. This paper adopts a stepwise logistic model to identify spatial, occupational-exposure, and cultural factors that affect malaria prevalence. According to the results, differences among individuals working and/or living in the gold mining areas could produce different exposure to the disease and thus to different risk of malaria prevalence. Understanding these differences may provide an important tool for identifying risk profiles in the gold mining and related population and for informing programs for prevention and treatment of malaria in the Amazon.
本文分析了巴西亚马逊州马托格罗索州北部野猫金矿营地（garimpos）工作人员中影响疟疾风险的因素。从历史上看，此类矿营是巴西亚马逊州疟疾患病率最高的地区。然而，很少有人关注从矿营自身的内部视角来了解这种疾病，比如采矿人群的特征及其空间组织。本文采用逐步逻辑模型来确定影响疟疾患病率的空间、职业暴露和文化因素。结果显示，在金矿地区工作和/或生活的个体之间的差异可能导致对该疾病的不同暴露程度，进而导致疟疾患病率的不同风险。了解这些差异可能为识别金矿开采及相关人群的风险状况以及为亚马逊地区疟疾防治项目提供重要工具。
