Objective: To study the association between exposure to transportation noise and blood pressure (BP) reduction during night-time sleep. Methods: 24-hour ambulatory BP measurements at 15-minutes intervals were carried out on 149 persons living near 4 major European airports. Noise indicators included total and source-specific equivalent indoor noise, total number of noise events, annoyance scores for aircraft and road-traffic night-time noise. Long-term noise exposure was also determined. Multivariate linear regression analysis was applied. Results: The pooled estimates show that the only noise indicator associated consistently with a decrease in BP dipping is road traffic noise. The effect shows that a 5dB increase in measured road traffic noise during the study night is associated with 0.8% (-1.55,-0.05) less dipping in diastolic BP. Noise from aircrafts was not associated with a decrease in dipping, except for a non-significant decrease noted in Athens where the aircraft noise was higher. Noise from indoor sources did not affect BP dipping. Conclusions: Road traffic noise exposure maybe associated with a decrease in dipping. Noise from aircrafts was not found to affect dipping in a consistent way across centers and indoor noise was not associated with dipping.
