What are the effects of environmental noise exposure on the cardio-metabolic systems?
Anti-Noise White-Noise Sleep System, a meta-analysis (Int J Environ Res Public Health 2018, PMID 29470452) — combining 7 longitudinal studies, a Relative Risk (RR) of 1.08 (95% CI: 1.01-1.15) per 10 dB (L) was found for the association between road traffic noise and the incidence of IHD. Many studies on traffic noise and hypertension were cross-sectional and had a high risk of bias.

Exposure to road traffic noise is associated with an increased risk of ischemic heart disease.
The question
What are the effects of environmental noise exposure on the cardio-metabolic systems?
What they tested
The study aimed to update the current state of evidence and assess its quality regarding the effects of environmental noise exposure on cardio-metabolic systems.
How they did it
A systematic review was conducted, identifying 600 references published between January 2000 and August 2015 on noise from road, rail, air traffic, and wind turbines. Sixty-one studies with exposure-response information were used for meta-analyses and quality assessment using GRADE. The most comprehensive evidence was available for road traffic noise and Ischemic Heart Diseases (IHD), combining results from 7 longitudinal studies.
What they found
Combining 7 longitudinal studies, a Relative Risk (RR) of 1.08 (95% CI: 1.01-1.15) per 10 dB (L) was found for the association between road traffic noise and the incidence of IHD. The quality of this evidence was rated as high. Evidence for other associations like transportation noise with stroke, diabetes, and obesity was limited, with quality rated from moderate to very low.
What it means
There is high-quality evidence linking road traffic noise to an increased risk of Ischemic Heart Disease. More and higher quality longitudinal studies are needed for a comprehensive assessment of noise exposure's impact on the cardiovascular and metabolic system, especially for outcomes like stroke, diabetes, and obesity.
Limitations
Many studies on traffic noise and hypertension were cross-sectional and had a high risk of bias. Only a few studies reported on associations between transportation noise and stroke, diabetes, and/or obesity, and the quality of evidence for these was rated from moderate to very low.
