A secondary data analysis was performed using an ecological design to study the association between malaria incidence rates, the reported annual production of gold mining extraction and monetary investments for the control of malaria from 1985 to 1996 in Mato Grosso, Brazil. A positive and statistically significant (p<0.001) association between the amount of gold extracted and MIR was obtained in multivariate regression analysis, even after allowing for financial investments in malaria control activities. This finding contributes to an understanding of the decrease observed in malaria incidence in Mato Grosso during the last decade, in view of the significant decrease in gold mining within the region during this period.
采用生态设计进行二次数据分析，以研究1985年至1996年巴西马托格罗索州疟疾发病率、报告的金矿开采年产量与疟疾控制资金投入之间的关联。在多变量回归分析中，即使考虑了疟疾控制活动的资金投入，仍发现黄金开采量与疟疾发病率之间存在正向且具有统计学意义（p<0.001）的关联。鉴于该地区在此期间金矿开采量显著下降，这一发现有助于理解马托格罗索州过去十年间疟疾发病率下降的情况。
