Exposure modifiers of the relationships between road traffic noise and aircraft noise with high blood pressure (HYENA study)

摘要

Within the framework of the multi-centred HYENA study, the relationship between roadtraffic noise, aircraft noise and hypertension was investigated. The data collectioncomprised a variety of potentially exposure modifying factors, including type of housing,location of rooms, window opening habits, use of noise reducing remedies, shielding due toobstacles and lengths of exposure. The quantitative role of these factors on the relationshipbetween noise and hypertension is explored (interaction terms, stratified analyses). Type ofhousing, length of residence, location of rooms and the use of noise reducing remediesmodified the relationship between noise and hypertension. However, the effects were notalways in the direction of a stronger association in the presumably higher exposedsubgroups.
