During autumn 2002 a large eruption of Mount Etna (Sicily, Italy) occurred. High levels (over 200 microg/m3) of total suspended particles (PM10) were recorded. The aim of the study was to evaluate the acute health effects on mortality and hospital admissions in the area around the volcano.
Deaths and hospital admissions occurring during the eruption period were compared with the corresponding figures during the same periods of the previous year (same day of the week). Relative risks, RR, and their 95% confidence intervals, CI, were computed. Variations in daily hospital admissions for cardiovascular diseases associated with daily level of PM10 were estimated.
No effects on overall and cause-specific mortality were observed during the eruption period. Increases were observed in hospital admissions for cardiovascular diseases (ischemic diseases: RR 1.31, 95% CI 1.10-1.56; myocardial infarction: RR 1.34, 95% CI 1.02-1.76) and for cerebrovascular diseases (RR 1.24, 95% CI 1.05-1.47). The excesses were stronger among the elderly. Daily admissions for cardiovascular diseases were not associated to PM10 levels.
The effects of the eruption of Mount Etna were limited to a temporary increase of cardiovascular morbidity, especially among the elderly, possibly as a consequence of stress.
2002年秋季，意大利西西里岛的埃特纳火山发生了一次大规模喷发。记录到总悬浮颗粒物（PM10）的高水平（超过200微克/立方米）。该研究的目的是评估火山周围地区喷发对死亡率和住院率的急性健康影响。
将喷发期间发生的死亡和住院情况与上一年同期（同一星期的同一天）的相应数据进行比较。计算相对风险（RR）及其95%置信区间（CI）。估计与PM10每日水平相关的心血管疾病每日住院人数的变化。
在喷发期间未观察到对总体死亡率和特定病因死亡率的影响。心血管疾病（缺血性疾病：RR 1.31，95%CI 1.10 - 1.56；心肌梗死：RR 1.34，95%CI 1.02 - 1.76）和脑血管疾病（RR 1.24，95%CI 1.05 - 1.47）的住院人数有所增加。老年人中的超额情况更为明显。心血管疾病的每日住院人数与PM10水平无关。
埃特纳火山喷发的影响仅限于心血管疾病发病率的暂时增加，尤其是在老年人中，这可能是压力导致的结果。
