The contribution of different transportation noise sources to metabolic disorders such as obesity remains understudied. We evaluated the associations of long-term exposure to road, railway and aircraft noise with measures of obesity and its subphenotypes using cross-sectional and longitudinal designs.

We assessed 3796 participants from the population-based Swiss Cohort Study on Air Pollution and Lung and Heart Diseases (SAPALDIA), who attended the visits in 2001 (SAP2) and 2010/2011 (SAP3) and who were aged 29–72 at SAP2. At SAP2 we measured body mass index (BMI, kg/m2). At SAP3 we measured BMI, waist circumference (centimetres) and Kyle body Fat Index (%) and derived overweight, central and general obesity. Longitudinally for BMI, we derived change in BMI, incidence of overweight and obesity and a 3-category outcome combining the latter two. We assigned source-specific 5-year mean noise levels before visits and during follow-up at the most exposed dwelling façade (Lden, dB), using Swiss noise models for 2001 and 2011 and participants' residential history. Models were adjusted for relevant confounders, including traffic-related air pollution.

Exposure to road traffic noise was significantly associated with all adiposity subphenotypes, cross-sectionally (at SAP3) [e.g. beta (95% CI) per 10 dB, BMI: 0.39 (0.18; 0.59); waist circumference: 0.93 (0.37; 1.50)], and with increased risk of obesity, longitudinally (e.g. RR = 1.25, 95% CI: 1.04; 1.51, per 10 dB in 5-year mean). Railway noise was significantly related to increased risk of overweight. In cross-sectional analyses, we further identified a stronger association between road traffic noise and BMI among participants with cardiovascular disease and an association between railway noise and BMI among participants reporting bad sleep. Associations were independent of the other noise sources, air pollution and robust to all adjustment sets. No associations were observed for aircraft noise.

Long-term exposure to transportation noise, particularly road traffic noise, may increase the risk of obesity and could constitute a pathway towards cardiometabolic and other diseases.

长期暴露于运输噪声中及其与肥胖标志物的关系以及肥胖的发展

不同运输噪声源对肥胖等代谢性疾病的贡献尚待研究。我们使用横断面和纵向设计评估了长期暴露于公路,铁路和飞机噪声与肥胖及其亚表型的关系。

我们评估了3796名基于人群的瑞士人群空气污染与肺与心脏病研究(SAPALDIA)的参与者,他们参加了2001年(SAP2)和2010/2011年(SAP3)的访问,年龄在29岁至72岁在SAP2。在SAP2,我们测量了体重指数(BMI,kg / m 2)。在SAP3中,我们测量了BMI,腰围(厘米)和Kyle身体脂肪指数(%),并得出了超重,中枢性肥胖和一般性肥胖。纵向上,对于BMI,我们得出了BMI的变化,超重和肥胖的发生率以及后两者的3类结果。我们使用2001年和2011年的瑞士噪声模型以及参与者的居住历史,为访问前和暴露最严重的住宅立面(Lden,dB)分配了特定来源的5年平均噪声水平。针对相关混杂因素(包括与交通相关的空气污染)对模型进行了调整。

道路交通噪声暴露与所有肥胖亚型显着相关,在横截面(在SAP3)[例如,每10 dB的beta(95%CI),BMI:0.39(0.18; 0.59);腰围:0.93(0.37; 1.50)],并且肥胖的风险在纵向上有所增加(例如RR = 1.25,95%CI:1.04; 1.51,每10 dB,5年平均值)。铁路噪音与超重风险增加显着相关。在横断面分析中,我们进一步确定了患有心血管疾病的参与者中道路交通噪声与BMI之间的关联更强,而报告睡眠不良的参与者中铁路噪声与BMI之间的关联更强。关联独立于其他噪声源,空气污染和对所有调整集的鲁棒性。没有观察到飞机噪音的关联。

长期暴露于交通噪声中,尤其是道路交通噪声中,可能会增加肥胖的风险,并可能成为代谢心脏疾病和其他疾病的途径。
