As urban populations grow, the problem of noise pollution becomes more significant. The limited number of epidemiological studies linking individual-level dynamic noise exposure to sleep highlights a gap in our understanding of how individual-level noise exposure impact sleep quality and duration. A cross-sectional survey was conducted in Hong Kong, and portable noise sensors were used to record participants' real-time noise exposure. The Pittsburgh Sleep Quality Index was used to assess their sleep quality. Logistic regression was used to examine the relationship of individual-level noise exposure with sleep quality and sleep duration. Among a total of 763 subjects included in the analysis, and a-weighted decibels [dB(A)] 24-h average exposure (L) was 63.21 (58.85-67.85) dB(A) for workday and 63.52 (59.03-67.86) dB(A) for non-workday. A significant decrease in individual noise level was observed closer to bedtime (P < 0.05). Compared with the lowest noise exposure, exposure to the highest noise level was positively associated with the presence of poor sleep quality for L, L and L, with an odds ratio (OR) and 95 % confidential interval (CI) of 1.53 (1.04-2.24), 1.65 (1.12-2.43), and 1.51 (1.03-2.21), respectively. Exposure to elevated noise level was associated with increased risk of shorter nocturnal sleep duration (< 7 h), the OR and 95 % CI was 1.87 (1.29-2.73) for L, 1.58 (1.09-2.30) for L, 1.50 (1.03-2.18) for L, and 1.60 (1.10-2.32) for L in the highest noise exposure group. Similar findings were observed both on workdays and non-workdays, respectively. Furthermore, the results showed that each 10 dB(A) increment in L and L was associated with a probable 29 % and 27 % increase in poor sleep quality and a 24 % and 24 % reduction in sleep duration. This study demonstrates that environmental noise exposure was associated with poor sleep quality and shorter sleep duration, posing a significant public health issue in Hong Kong.
随着城市人口的增长，噪声污染问题变得更加严重。有限的流行病学研究将个体水平的动态噪声暴露与睡眠联系起来，突出了我们对个体水平噪声暴露如何影响睡眠质量和持续时间的理解存在差距。在香港进行了一项横断面调查，并使用便携式噪声传感器记录参与者的实时噪声暴露。匹兹堡睡眠质量指数用于评估他们的睡眠质量。使用逻辑回归检查个体噪声暴露与睡眠质量和睡眠时间的关系。在总共纳入分析的 763 名受试者中，工作日的 24 小时平均加权分贝（dB（A））暴露（L）为 63.21（58.85-67.85）dB（A），非工作日为 63.52（59.03-67.86）dB（A）。靠近就寝时间时，个体噪声水平显著降低（P<0.05）。与最低噪声暴露相比，最高噪声水平的暴露与睡眠质量差的存在呈正相关，对于 L、L 和 L，比值比（OR）和 95%置信区间（CI）分别为 1.53（1.04-2.24）、1.65（1.12-2.43）和 1.51（1.03-2.21）。暴露于较高噪声水平与夜间睡眠时间较短（<7 小时）的风险增加相关，OR 和 95%CI 分别为 L 为 1.87（1.29-2.73）、L 为 1.58（1.09-2.30）、L 为 1.50（1.03-2.18）和 L 为 1.60（1.10-2.32）。在最高噪声暴露组中分别观察到工作日和非工作日的类似发现。此外，结果表明，L 和 L 每增加 10dB（A），睡眠质量差的可能性分别增加 29%和 27%，睡眠时间分别减少 24%和 24%。本研究表明，环境噪声暴露与睡眠质量差和睡眠时间短有关，这是香港的一个重大公共卫生问题。
