Epidemiologic evidence linking environmental noise to obesity and hypertension remains scarce, especially in children, and the results remain inconclusive. This study aims to examine the cross-sectional associations of self-reported residential noise exposure with obesity and hypertension in children and adolescents.
As an ongoing study, a representative sample of the children aged 6-9 years in Chongqing were selected in 2014. In 2019, self-reported residential noise (answer categories: "very quiet," "moderately quiet," "slightly quiet," and "not at all quiet") data were collected, and 3,412 participants with completed data were included in the analyses.
Participants living in a quieter area had a significantly lower risk of obesity than those living in a noisy area (very quiet: OR = 0.50, 95%CI: 0.29-0.88, = 0.015; moderately quiet: OR = 0.61, 95%CI: 0.36-1.02, = 0.059). Similar associations were observed for abdominal obesity, although did not reach statistical significance. Consistently, residential noise exposure was significantly associated with body mass index (BMI) and waist-to-height ratio. Self-reported residential noise exposure was positively associated with systolic blood pressure (β = -1.808; 95%CI = -3.495, -0.110; = 0.037). When sleep quality, study stress, BMI, and vegetable/fruits consumption were further adjusted, all effect estimates decreased, and no statistical association was observed between noise exposure and blood pressure. Furthermore, we found that the mediating effects of obesity on the associations of self-reported residential noise exposure with hypertension were 6.8% (% of total effect mediated = 0.068, 95%CI: -2.58, 3.99), although did not reach statistical significance.
Self-reported residential noise exposure was associated with a higher risk of obesity or abdominal obesity. Also, self-reported residential noise exposure was positively associated with hypertension, and obesity may partially mediate this association, but did not reach statistical significance.
将环境噪声与肥胖症和高血压联系起来的流行病学证据仍然很少，尤其是在儿童中，而且结果尚无定论。本研究旨在探讨自我报告的居住噪声暴露与儿童和青少年肥胖症及高血压之间的横断面关联。
作为一项正在进行的研究，2014年在重庆选取了具有代表性的6至9岁儿童样本。2019年，收集了自我报告的居住噪声（回答类别：“非常安静”、“适度安静”、“稍微安静”和“一点也不安静”）数据，3412名数据完整的参与者被纳入分析。
居住在较安静地区的参与者患肥胖症的风险显著低于居住在嘈杂地区的参与者（非常安静：OR = 0.50，95%CI：0.29 - 0.88，P = 0.015；适度安静：OR = 0.61，95%CI：0.36 - 1.02，P = 0.059）。腹部肥胖也观察到类似关联，尽管未达到统计学显著性。同样，居住噪声暴露与体重指数（BMI）和腰高比显著相关。自我报告的居住噪声暴露与收缩压呈正相关（β = -1.808；95%CI = -3.495，-0.110；P = 0.037）。当进一步调整睡眠质量、学习压力、BMI和蔬菜/水果摄入量时，所有效应估计值均降低，且未观察到噪声暴露与血压之间的统计学关联。此外，我们发现肥胖症对自我报告的居住噪声暴露与高血压关联的中介效应为6.8%（中介效应占总效应的百分比 = 0.068，95%CI：-2.58，3.99），尽管未达到统计学显著性。
自我报告的居住噪声暴露与肥胖症或腹部肥胖的较高风险相关。此外，自我报告的居住噪声暴露与高血压呈正相关，肥胖症可能部分介导这种关联，但未达到统计学显著性。
