2003年8月，欧洲各地出现了创纪录的高温，法国是受影响最严重的国家。在此期间，全国各地都测得臭氧浓度升高。有人提出了关于臭氧对2003年夏季热浪的健康影响的贡献的问题。我们使用时间序列设计来分析温度和O3污染对死亡率的短期影响。死亡人数根据温度和O3水平进行回归，控制可能的混杂因素：长期趋势，季节，流感爆发，一周中的一天和银行假日影响。为了与先前的结果进行比较，我们使用随机效应方法和经验贝叶斯方法计算了合并的超额风险。对于这9个城市来说，O3浓度每增加10 μg/m3，死亡的超额危险性显著（1.01%，95%可信区间，0.58-1.44）。在2003年8月3日至17日期间，与O3和温度相关的死亡超额风险范围从勒阿弗尔的10.6%到巴黎的174.7%。当我们比较了O3和温度对这一联合超额风险的相对贡献时，O3的贡献因城市而异，从波尔多的2.5%到图卢兹的85.3%不等。我们观察到的异质性之间的9个城市不仅为O3和温度的联合作用，但也为每个因素的相对贡献。这些结果证实，在城市地区，臭氧水平对公共健康有不可忽视的影响。
During August 2003, record high temperatures were observed across Europe, and France was the country most affected. During this period, elevated ozone concentrations were measured all over the country. Questions were raised concerning the contribution of O3 to the health impact of the summer 2003 heat wave. We used a time-series design to analyze short-term effects of temperature and O3 pollution on mortality. Counts of deaths were regressed on temperatures and O3 levels, controlling for possible confounders: long-term trends, season, influenza outbreaks, day of the week, and bank holiday effects. For comparison with previous results of the nine cities, we calculated pooled excess risk using a random effect approach and an empirical Bayes approach. For the nine cities, the excess risk of death is significant (1.01%; 95% confidence interval, 0.58–1.44) for an increase of 10 μg/m3 in O3 level. For the 3–17 August 2003 period, the excess risk of deaths linked to O3 and temperatures together ranged from 10.6% in Le Havre to 174.7% in Paris. When we compared the relative contributions of O3 and temperature to this joint excess risk, the contribution of O3 varied according to the city, ranging from 2.5% in Bordeaux to 85.3% in Toulouse. We observed heterogeneity among the nine cities not only for the joint effect of O3 and temperatures, but also for the relative contribution of each factor. These results confirmed that in urban areas O3 levels have a non-negligible impact in terms of public health.
