RESUMO
OBJECTIVE: The objective of our study was to investigate and evaluate the relationship between road traffic noise and cardiovascular risk. METHODS: The 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, L(eq,24h)=67+/-2dB(A)) and a control group (n=379, L(eq,24h)=58.7+/-6dB(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). RESULTS: Cardiovascular 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)). CONCLUSIONS: These findings highlight the association between road traffic noise and cardiovascular risk.
