◆インペリアル・カレッジ・ロンドンの研究によれば、夜遅くに飛行機の音が聞こえると、翌日の心臓関連の入院患者数がわずかに増加する可能性がある。特に65歳以上の男性や黒人にとってリスクが高いことがわかった。一方、飛行機の騒音と心臓疾患の死亡との関連は見られなかった。

◆飛行機の騒音は睡眠の妨げになり、一時的に血圧を上昇させ、心血管の問題のリスクを増加させる可能性がある。長期的な研究でも飛行機の騒音とリスクの関連が示されており、研究者は対策を取る必要があると主張している。

飛行機の騒音と翌日の心臓の健康状態との関連性(Airplane noise linked to next day heart health hospitalisations)

Abstract

Aircraft noise causes annoyance and sleep disturbance and there is some evidence of associations between long-term exposures and cardiovascular disease (CVD). We investigated short-term associations between previous day aircraft noise and cardiovascular events in a population of 6.3 million residing near Heathrow Airport using a case-crossover design and exposure data for different times of day and night. We included all recorded hospitalisations (n = 442,442) and deaths (n = 49,443) in 2014–2018 due to CVD. Conditional logistic regression was used to estimate the ORs and adjusted for NO2 concentration, temperature, and holidays. We estimated an increase in risk for 10 dB increment in noise during the previous evening (Leve OR = 1.007, 95% CI 0.999–1.015), particularly from 22:00–23:00 h (OR = 1.007, 95% CI 1.000–1.013), and the early morning hours 04:30–06:00 h (OR = 1.012, 95% CI 1.002–1.021) for all CVD admissions, but no significant associations with day-time noise. There was effect modification by age-sex, ethnicity, deprivation, and season, and some suggestion that high noise variability at night was associated with higher risks. Our findings are consistent with proposed mechanisms for short-term impacts of aircraft noise at night on CVD from experimental studies, including sleep disturbance, increases in blood pressure and stress hormone levels and impaired endothelial function.
