To identify areas and risk factors in cardiovascular disease (CD) mortality associated with air pollution from high exposure to vehicular traffic.
Cross-sectional study of CD mortality in 2,617 individuals aged 45-85 years living in the urban area of Cuiabá and Várzea Grande, Mato Grosso State, Brazil, between 2009 and 2011. We used the residential proximity of up to 150 meters to a roadway of great vehicle flow as a proxy of high exposure to air pollution from vehicular traffic. The association between age, gender, income, and traffic intensity with vehicular traffic exposure was assessed through the multiple logistic regression. We conducted stratified analyses to observe the influence of seasons and groups of causes. We used Bernoulli's spatial model of probability to identify high-risk clusters.
Risk factors for CD mortality associated with high exposure to vehicular traffic were: living in census tracts with very unequal income (OR = 1.78; 95%CI 1.36 - 2.33), heavy traffic (OR = 1.20; 95%CI 1.01 - 1.43), and female gender (OR = 1.18; 95%CI 1.01 - 1.38). The CD mortality risk increases about 10% during the dry season period. We identified nine areas of risk.
High exposure to traffic is associated with CD mortality in Cuiabá and Várzea Grande. Income inequality, traffic intensity, and female gender presented as the main determiners for this exposure. The dry season period enhances the effects of traffic exposure.
确定与高暴露于车辆交通产生的空气污染相关的心血管疾病（CD）死亡的区域和风险因素。
对2009年至2011年期间居住在巴西马托格罗索州库亚巴和大瓦尔泽亚市区的2617名45 - 85岁个体的CD死亡率进行横断面研究。我们将距离车流量大的道路至多150米的居住 proximity作为高暴露于车辆交通空气污染的替代指标。通过多元逻辑回归评估年龄、性别、收入和交通强度与车辆交通暴露之间的关联。我们进行分层分析以观察季节和病因组的影响。我们使用伯努利概率空间模型来识别高风险集群。
与高暴露于车辆交通相关的CD死亡风险因素为：生活在收入极不平等的人口普查区（OR = 1.78；95%CI 1.36 - 2.33）、交通繁忙（OR = 1.20；95%CI 1.01 - 1.43）以及女性性别（OR = 1.18；95%CI 1.01 - 1.38）。在旱季期间，CD死亡风险增加约10%。我们确定了九个风险区域。
在库亚巴和大瓦尔泽亚，高暴露于交通与CD死亡率相关。收入不平等、交通强度和女性性别是这种暴露的主要决定因素。旱季会增强交通暴露的影响。
