Abstract

Background and methodology

Air pollutants have a significant impact on public health.

The aim of the study was to find out the relationship between ambulatory blood pressure measured by 24-h ambulatory blood pressure monitoring (ABPM) and the atmospheric pollutants that are measured regularly (PM₁₀, PM_2.5, NO₂ and SO₂). An observational study of temporal and geographic measurements of individual patients (case-time series design) was carried out in Primary Care Centres and Hypertension Units in the Barcelona metropolitan area. We included 2888 hypertensive patients ≥ 18 years old, untreated, with a first valid ABPM performed between 2005 and 2014 and with at least one air pollution station within a radius of <3 km.

Results and conclusions

The mean age was 54.3 (SD 14.6) years. 50.1% were women and 16.9% of the sample were smokers. Mean 24-h blood pressure (BP) was 128.0 (12.7)/77.4 (9.7) mmHg. After adjusting for mean ambient temperature and different risk factors, a significant association was found between ambulatory diastolic BP (DBP) and PM₁₀ concentrations the day before ABPM. For each increase of 10 μg/m³ of PM₁₀, an increase of 1.37 mmHg 24-h DBP and 1.48 mmHg daytime DBP was observed. No relationship was found between PM_2.5, NO₂ and SO₂ and ambulatory BP, nor between any pollutant and clinical BP.

The concentration of PM₁₀ the day before the ABPM is significantly associated with an increase in 24-h DBP and daytime DBP.

空气污染物对动态血压的影响。

背景和方法：空气污染物对公众健康有重大影响。本研究的目的是找出24小时动态血压监测（ABPM）测量的动态血压与定期测量的大气污染物（PM10、PM2.5、NO2和SO2）之间的关系。在巴塞罗那大都会区的初级保健中心和高血压病房，对个体患者的时间和地理测量进行了观察性研究（病例时间序列设计）。我们纳入了2888名年龄≥18岁、未经治疗的高血压患者，他们在2005年至2014年间首次进行了有效的ABPM，并且在半径范围内至少有一个空气污染站。结果和结论：平均年龄为54.3（SD 14.6）岁。50.1%为女性，16.9%为吸烟者。24小时平均血压为128.0（12.7）/77.4（9.7）mmHg。在调整了平均环境温度和不同的风险因素后，发现动态舒张压（DBP）与ABPM前一天的PM10浓度之间存在显著相关性。PM10每增加10μg/m3，24小时DBP和日间DBP分别增加1.37mmHg和1.48mmHg。PM2.5、NO2和SO2与动态血压之间没有关系，任何污染物与临床血压之间也没有关系。ABPM前一天的PM10浓度与24小时DBP和日间DBP的增加显著相关。
