Copyright © (2015) by EAA-NAG-ABAV, All rights reserved Exposure to road traffic noise may increase risk of hypertension. Ambient air pollution may be a confounder in this relationship, as both noise and air pollution originate from traffic and both may be associated with hypertension. We investigated associations of road traffic noise with blood pressure and heart rate, while taking into account exposure to ambient air pollution, in three European cohorts using a harmonized approach. Data were obtained from LifeLines (the Netherlands), EPIC-Oxford (UK) and HUNT (Norway). Road traffic noise exposure was assessed using a European noise model based on Common Noise Assessment Methods in Europe (CNOSSOS-EU). Exposure to particulate matter with a diameter ≤10 μm (PM10) and nitrogen dioxide (NO2) was estimated using a European land use regression model. Both systolic and diastolic blood pressure and heart rate measurements were conducted by trained medical professionals within each participating cohort. Federated analysis of harmonized data for the three cohorts will be conducted at the individual level using the DataSHIELD approach. Data from 123,366 participants, with a mean age of 47.6 years, were available for the current study. Median annual average day-evening-night levels of road traffic noise (Lden) were 54.7 dB(A) (LifeLines), 54.8 dB(A) (EPIC-Oxford), and 49.4 dB(A) (HUNT). Results from pooled linear regression analyses adjusted for sex, age, and ambient air pollution will be presented at the conference. Pooling harmonized data from multiple European cohorts allows the use of large sample sizes with a wide noise exposure range. Findings from this study will contribute to the knowledge about harmful effects of road traffic noise on cardiovascular health.
