Abstract
In 2013–2015, a consortium of European scientists – NEWDANUBE – was established to prepare a birth cohort in the Danube region, including most of the countries with the highest air pollution in Europe, the area being one-fifth of the European Union's (EU's) territory, including 14 countries (nine EU member states), over 100 million inhabitants, with numerous challenges: big socioeconomic disparities, and a region-specific environmental pollution. The consortium reflects the EU Strategy for the Danube Region Strategy (2010), which identified 11 thematic Priority Areas – one of which is the environmental risks. Birth cohorts have been established in all other areas of Europe and collaborative efforts in promoting maternal and fetal health by minimizing the environmental exposures have been initiated with national, European, and international financial support. A birth cohort in the Danube area could apply the established methodologies for prenatal exposure and birth outcome measurements and establish a platform for targeted health promotion in couples planning pregnancies. The consortium included a strong socioeconomic part focusing on the participant's active registration of exposures to environmental toxicants and health indicators of disease and wellbeing, combined with investigation of their risk-reducing behavior and interventions to change their lifestyle to avoid the adverse health risks. Willingness to pay for reducing the health risks in children is also proposed to be estimated. Further collaboration and networking is encouraged as the Danube region has several decades of experience and expertise in biomonitoring adult populations exposed environmentally or occupationally. Additionally, some countries in the Danube region launched small-scale birth cohorts encouraged by participation in several ongoing research projects.

BACKGROUND: Road traffic noise has been linked to increased risk of ischemic heart disease, yet evidence on stroke shows mixed results. We examine the association between long-term exposure to road traffic noise and incidence of stroke, overall and by subtype (ischemic or hemorrhagic), after adjustment for air pollution. METHODS: Twenty-five thousand six hundred and sixty female nurses from the Danish Nurse Cohort recruited in 1993 or 1999 were followed for stroke-related first-ever hospital contact until December 31st, 2014. Full residential address histories since 1970 were obtained and annual means of road traffic noise (Lden [dB]) and air pollutants (particulate matter with diameter < 2.5 μm and < 10 μm [PM2.5 and PM10], nitrogen dioxide [NO2], nitrogen oxides [NOx]) were determined using validated models. Time-varying Cox regression models were used to estimate hazard ratios (HR) (95% confidence intervals [CI]) for the associations of one-, three-, and 23-year running means of Lden preceding stroke (all, ischemic or hemorrhagic), adjusting for stroke risk factors and air pollutants. The World Health Organization and the Danish government's maximum exposure recommendations of 53 and 58 dB, respectively, were explored as potential Lden thresholds. RESULTS: Of 25,660 nurses, 1237 developed their first stroke (1089 ischemic, 148 hemorrhagic) during 16 years mean follow-up. For associations between a 1-year mean of Lden and overall stroke incidence, the estimated HR (95% CI) in the fully adjusted model was 1.06 (0.98-1.14) per 10 dB, which attenuated to 1.01 (0.93-1.09) and 1.00 (0.91-1.09) in models further adjusted for PM2.5 or NO2, respectively. Associations for other exposure periods or separately for ischemic or hemorrhagic stroke were similar. There was no evidence of a threshold association between Lden and stroke. CONCLUSIONS: Long-term exposure to road traffic noise was suggestively positively associated with the risk of overall stroke, although not after adjusting for air pollution.

Objective To investigate the associations between air pollution and mortality, focusing on associations below current European Union, United States, and World Health Organization standards and guidelines. Design Pooled analysis of eight cohorts. Setting Multicentre project Effects of Low-Level Air Pollution: A Study in Europe (ELAPSE) in six European countries. Participants 325 367 adults from the general population recruited mostly in the 1990s or 2000s with detailed lifestyle data. Stratified Cox proportional hazard models were used to analyse the associations between air pollution and mortality. Western Europe-wide land use regression models were used to characterise residential air pollution concentrations of ambient fine particulate matter (PM 2.5), nitrogen dioxide, ozone, and black carbon. Main outcome measures Deaths due to natural causes and cause specific mortality. Results Of 325 367 adults followed-up for an average of 19.5 years, 47 131 deaths were observed. Higher exposure to PM 2.5, nitrogen dioxide, and black carbon was associated with significantly increased risk of almost all outcomes. An increase of 5 μg/m 3 in PM 2.5 was associated with 13% (95% confidence interval 10.6% to 15.5%) increase in natural deaths; the corresponding figure for a 10 μg/m 3 increase in nitrogen dioxide was 8.6% (7% to 10.2%). Associations with PM 2.5, nitrogen dioxide, and black carbon remained significant at low concentrations. For participants with exposures below the US standard of 12 μg/m 3 an increase of 5 μg/m 3 in PM 2.5 was associated with 29.6% (14% to 47.4%) increase in natural deaths. Conclusions Our study contributes to the evidence that outdoor air pollution is associated with mortality even at low pollution levels below the current European and North American standards and WHO guideline values. These findings are therefore an important contribution to the debate about revision of air quality limits, guidelines, and standards, and future assessments by the Global Burden of Disease.
