  1. Industrial noise exposure, noise annoyance, and serum lipid levels in blue-collar workers-the CORDIS study.

    Article - En anglais

    Chronic noise exposure may constitute a risk factor for cardiovascular disease, but the exact mechanism is unclear.

    The authors studied the association between industrial noise exposure, noise annoyance, and serum lipid/lipoprotein levels in male (n=1 455) and female (n=624) blue-collar workers.

    The authors found that young men (i.e., ¾ 44 y of age) exposed to high noise levels (= 80 dB[A]) had higher total levels of cholesterol (p=023) and triglycerides (p=001), as well as a higher cholesterol ratio (p=038), than men exposed to low noise levels, even after controlling for confounding variables.

    In women or in older (>45 y) men, noise did not affect serum lipid/lipoprotein levels.

    The authors found no interaction between noise exposure level and noise annoyance (except for high-density lipoprotein in women).

    However, noise annoyance covaried independently with total cholesterol (p=022) and high-density lipoprotein (p=0039) levels in young men and with total cholesterol (p=035), triglyceride (p=035), and high-density lipoprotein levels in women (under high noise exposure conditions) (p=048) levels in women.

    Noise annoyance and noise exposure levels had an additive effect on cholesterol levels.

    Young men who scored high on both variables had a 15-mg/dl higher mean cholesterol level (95% confidence interval [Cl]=7.2,22.8 ; p=0003) than those who scored low on both variables ; in women, the corresponding difference was 23 mg/dl (95% Cl=1.5,42.9 ; p=019). (...)
