This paper sought to quantify the particulate matter (PM(2.5)) pollutant's impact on short-term daily respiratory-cause mortality in the city of Madrid.
As our dependent variable, we took daily mortality registered in Madrid from 1 January 2003 to 31 December 2005, attributed to all diseases of the respiratory system as classified under heads J00-J99 of the ICD 10 and broken down as follows: J12-J18, pneumonia; J40-J44, chronic diseases of the respiratory system except asthma; J45-J46, asthma; and J96, respiratory failure.
The relative risk (RR) for daily overall respiratory mortality was RR 1.0281 (1.0043-1.0520), with a proportional attributable risk (PAR) of 2.74%. This effect occurred in lag 1; respiratory failure, RR 1.0816 (1.0119-1.1512) and PAR 7.54% at lag 5; and pneumonia, RR 1.0438 (1.0001-1.0875) and PAR 4.19% at lag 6.
Our results reflect the association that exists between PM(2.5) concentrations and daily respiratory-cause mortality.
本文旨在量化马德里市细颗粒物（PM(2.5)）污染对短期每日呼吸道疾病死亡率的影响。
本研究的因变量为 2003 年 1 月 1 日至 2005 年 12 月 31 日期间马德里市登记的每日死亡率，归因于 ICD 10 第 J00-J99 章分类的所有呼吸系统疾病，细分为：J12-J18，肺炎；J40-J44，除哮喘外的慢性呼吸系统疾病；J45-J46，哮喘；J96，呼吸衰竭。
每日整体呼吸道死亡率的相对风险（RR）为 RR 1.0281（1.0043-1.0520），比例归因风险（PAR）为 2.74%。这种影响发生在第 1 天滞后；呼吸衰竭的 RR 为 1.0816（1.0119-1.1512）和 PAR 为 7.54%，在第 5 天滞后；肺炎的 RR 为 1.0438（1.0001-1.0875）和 PAR 为 4.19%，在第 6 天滞后。
我们的结果反映了 PM(2.5)浓度与每日呼吸道疾病死亡率之间的关联。
