Previous research suggests an association between road traffic noise and obesity, but current evidence is inconclusive. The aim of this study was to assess the association between nocturnal noise exposure and markers of obesity and to assess whether sleep disturbance might be a mediator in this association.
We applied data from the Respiratory Health in Northern Europe (RHINE) cohort. We used self-measured waist circumference (WC) and body mass index (BMI) as outcome values. Noise exposure was assessed as perceived traffic noise in the bedroom and/or the bedroom window's location towards the street. We applied adjusted linear, and logistic regression models, evaluated effect modifications and conducted mediation analysis.
Based on fully adjusted models we found that women, who reported very high traffic noise levels in bedroom, had 1.30 (95% CI 0.24-2.37) kg/m higher BMI and 3.30 (95% CI 0.39-6.20) cm higher WC compared to women, who reported no traffic noise in the bedroom. Women who reported higher exposure to road traffic noise had statistically significant higher odds of being overweight and have abdominal obesity with OR varying from 1.15 to 1.26 compared to women, who reported no traffic noise in the bedroom. For men, the associations were rather opposite, although mostly statistically insignificant. Furthermore, men, who reported much or very much traffic noise in the bedroom, had a statistically significantly lower risk of abdominal obesity. Sleep disturbance fully or partially mediated the association between noise in bedroom and obesity markers among women.
Our results suggest that self-reported traffic noise in the bedroom may be associated to being overweight or obese trough sleep disturbance among women, but associations were inconclusive among men.
先前的研究表明道路交通噪声与肥胖之间存在关联，但目前的证据尚无定论。本研究旨在评估夜间噪声暴露与肥胖标志物之间的关系，并评估睡眠障碍是否可能是这种关联的中介因素。
我们应用了北欧呼吸健康研究（RHINE）队列的数据。我们将自我测量的腰围（WC）和体重指数（BMI）作为结果值。噪声暴露评估为卧室和/或卧室窗户朝向街道的位置感知到的交通噪声。我们应用了调整后的线性和逻辑回归模型，评估了效应修饰并进行了中介分析。
基于完全调整的模型，我们发现报告卧室交通噪声非常高的女性的 BMI 比报告卧室无交通噪声的女性高 1.30（95%CI 0.24-2.37）kg/m，WC 高 3.30（95%CI 0.39-6.20）cm。报告暴露于道路交通噪声较高的女性超重和腹部肥胖的几率与报告卧室无交通噪声的女性相比具有统计学意义，OR 从 1.15 到 1.26 不等。对于男性，关联则相反，尽管大多数关联没有统计学意义。此外，报告卧室交通噪声较大或非常大的男性患腹部肥胖的风险统计学上显著降低。睡眠障碍完全或部分介导了卧室噪声与女性肥胖标志物之间的关联。
我们的研究结果表明，自我报告的卧室交通噪声可能通过女性的睡眠障碍与超重或肥胖有关，但在男性中关联尚无定论。
