Traffic levels have been found a significant environmental predictor for physical inactivity. A recent study suggested that traffic noise annoyance was associated with lower physical activity.
We investigated associations between modelled residential traffic noise and leisure-time sports.
In the Diet, Cancer and Health cohort, we performed cross-sectional analyses using data from the baseline questionnaire (1993-97), and longitudinal analyses of change between baseline and follow-up (2000-02). People reported participation (yes/no) and hours of leisure-time sport, from which we calculated MET hrs/week. Present and historical addresses from 1987 to 2002 were found in national registries, and traffic noise was modelled 1 and 5 years before enrolment, and from baseline to follow-up. Analyses were performed using logistic and linear regression.
Traffic noise exposure 5 years before baseline was associated with higher prevalence odds ratio of non-participation in leisure-time sports; significantly for road traffic noise (odds ratio (OR): 1.10; 95% confidence interval (CI): 1.07-1.13) and borderline for railway noise (OR: 1.03; 95% CI: 0.99-1.07), per 10dB. In longitudinal analyses, a 10dB higher road traffic noise was associated with a higher prevalence odds ratio of ceasing (OR: 1.12; 95% CI: 1.07-1.18) and a lower prevalence odds ratio of initiating (OR: 0.92; 95% CI: 0.87-0.96) leisure-time sports. Exposure to railway noise was negatively associated with baseline MET hrs/week, whereas no association was found in longitudinal analyses, or for road traffic noise.
The study suggests that long-term exposure to residential road traffic noise is negatively associated with leisure-time sports. Results for railway noise were less consistent.
交通水平已被发现是身体活动不足的一个重要环境预测因素。最近一项研究表明，交通噪音烦恼与较低的身体活动有关。
我们调查了模拟的住宅交通噪音与休闲运动之间的关联。
在饮食、癌症与健康队列研究中，我们使用基线调查问卷（1993 - 1997年）的数据进行横断面分析，并对基线与随访（2000 - 2002年）之间的变化进行纵向分析。人们报告了参与情况（是/否）以及休闲运动的时长，据此我们计算每周的代谢当量小时数。1987年至2002年的当前和历史住址来自国家登记处，交通噪音在入组前1年和5年以及从基线到随访期间进行模拟。分析采用逻辑回归和线性回归。
基线前5年的交通噪音暴露与休闲运动不参与的患病率比值比升高有关；每增加10分贝，道路交通噪音显著相关（比值比（OR）：1.10；95%置信区间（CI）：1.07 - 1.13），铁路噪音接近显著（OR：1.03；95% CI：0.99 - 1.07）。在纵向分析中，道路交通噪音每升高10分贝，与休闲运动停止的患病率比值比升高（OR：1.12；95% CI：1.07 - 1.18）以及开始休闲运动的患病率比值比降低（OR：0.92；95% CI：0.87 - 0.96）有关。铁路噪音暴露与基线时每周的代谢当量小时数呈负相关，而在纵向分析中未发现关联，道路交通噪音也未发现关联。
该研究表明，长期暴露于住宅道路交通噪音与休闲运动呈负相关。铁路噪音的结果不太一致。
