朝鲜半岛有着悠久的历史，在春季，蒙古和中国的沙漠风吹来的沙尘云被称为亚洲沙尘事件。公众对这种沙尘可能造成的不利影响的担忧增加了，因为沙尘是在经过工业化程度很高的中国东部之后到达韩国的。本研究探讨了1995-1998年期间亚洲沙尘事件对韩国首尔每日死亡率的影响。我们使用泊松回归分析评估了每日死亡人数与沙尘事件之间的关联，并根据时间趋势、天气变量和一周中的哪一天进行了调整。在1995年和1998年之间，我们在首尔确定了28个亚洲沙尘日。根据3天接触移动平均数，估计死亡率增加百分比为1.7%。（95/置信区间：-1.6至5.3）对于所有原因，2.2%（95%置信区间：-3.5至8.3），（95%置信区间：-3.8至12.6）心血管和呼吸系统原因。我们的研究结果提供了弱证据表明，亚洲沙尘事件与各种原因的死亡风险有关。然而，沙尘事件与心血管和呼吸道疾病死亡之间的关联更强，这表明患有晚期心血管和呼吸道疾病的人可能对亚洲沙尘事件敏感。(C)2002 Elsvier Science（美国）。
The Korean peninsula has a long history of dust clouds blown by winds from the and deserts of Mongolia and China in springtime; these are called Asian dust events. Public concern about the possible adverse effects of this dust has increased, because the dust arrives in Korea after having passed over heavily industrialized eastern China. The present study explored the effect of Asian dust events on daily mortality in Seoul, South Korea, during the period 1995-1998. We evaluated the association between daily death counts and the dust events using Poisson regression analysis, adjusted for time trends, weather variables, and the day of the week. Between 1995 and 1998, we identified 28 Asian dust days in Seoul. The estimated percentage increase in the rate of deaths from 3-day moving averages of exposure was 1.7% (95/ confidence interval: - 1.6 to 5.3) for all causes, 2.2% (95% confidence interval: - 3.5 to 8.3) for deaths of persons aged 65 years and older, and 4.1% (95% confidence interval: - 3.8 to 12.6) for cardiovascular and respiratory causes. Our results provide weak evidence that the Asian dust events are associated with risk of death from all causes. However, the association between the dust events and deaths from cardiovascular and respiratory causes was stronger and it suggests that persons with advanced cardiovascular and respiratory disease may be susceptible to the Asian dust events.
