Community response to environmental noise and the impact on cardiovascular
risk score
Science of The Total Environment, (2010)Abstract
ObjectiveThe objective of our study was to investigate and evaluate
the relationship between road traffic noise and cardiovascular risk.MethodsThe
study sample (n = 659; 36.9% male, 63.1% female university students,
mean age 22.83 ± 1.58 years) included a group exposed to road traffic
noise (n = 280, Leq,24 h = 67 ± 2 dB(A)) and a control group (n =
379, Leq,24 h = 58.7 ± 6 dB(A)). Subjective response was determined
by a validated noise annoyance questionnaire. The ten year risk of
developing a coronary heart disease event was quantified as an evaluation
of cardiovascular risk (SCORE60, Framingham 10-year risk estimation
and projection to the age of 60, relative risk SCORE chart).ResultsCardiovascular
risk scores were significantly higher in the exposed group based
on the Framingham scores projected to the age of 60, SCORE60 (AOR
= 2.72 (95% CI = 1.21–6.15)) and the relative risk SCORE chart (AOR
= 2.81 (1.46–5.41)).ConclusionsThese findings highlight the association
between road traffic noise and cardiovascular risk.
