Abstract

OBJECTIVES To investigate whether there is a relation between residential exposure to aircraft noise and hypertension.

METHODS The study population comprised two random samples of subjects aged 19–80 years, one including 266 residents in the vicinity of Stockholm Arlanda airport, and another comprising 2693 inhabitants in other parts of Stockholm county. The subjects were classified according to the time weighted equal energy and maximum aircraft noise levels at their residence. A questionnaire provided information on individual characteristics including history of hypertension.

RESULTS The prevalence odds ratio for hypertension adjusted for age, sex, smoking, and education was 1.6 (95% confidence interval (95% CI) 1.0 to 2.5) among those with energy averaged aircraft noise levels exceeding 55 dBA, and 1.8 (95% CI 1.1 to 2.8) among those with maximum aircraft noise levels exceeding 72 dBA. An exposure-response relation was suggested for both exposure measures. The exposure to aircraft noise seemed particularly important for older subjects and for those not reporting impaired hearing ability.

CONCLUSIONS Community exposure to aircraft noise may be associated with hypertension.

  • Exposure to aircraft noise may be a risk factor for hypertension.

  • It is suggested that special attention be paid to maximum noise levels because of possible physiological effects from aircraft noise.
