Environmental noise exposure has been shown to affect children's cognition, but the concept of cognition is multifaceted, and studies on associations with noise are still inconclusive and fragmented. We studied cognitive change within one year in 882 adolescents aged 10-17 years in response to road traffic noise exposure. Participants filled in a comprehensive questionnaire and underwent cognitive testing twice at an interval of one year. Figural and verbal memory was measured with the Intelligenz-Struktur-Test (IST), and concentration accuracy and constancy were measured with FAKT-II and d2 test. Exposure to noise and other environmental stressors were modelled for school and home location at baseline. Missing data was addressed with multiple imputation. Cross-sectional multilevel analyses and longitudinal change score analyses were performed. In cross-sectional analyses, figural memory was significantly reduced by -0.27 (95%CI -0.49,-0.04) units per 10 dB road traffic noise increase at home (L). Longitudinal analyses showed a significant reduction of concentration constancy Z-scores between baseline and follow-up by -0.13 (95%CI -0.25, 0.00) per 10 dB road traffic noise at home (L). Our study indicates that road traffic noise at home reduces cognitive performance in adolescents. Larger cohorts with longer follow-up time are needed to confirm these results.
环境噪声暴露已被证明会影响儿童的认知，但认知的概念是多方面的，关于与噪声关联的研究仍然没有定论且较为零散。我们研究了882名10至17岁青少年在一年内因道路交通噪声暴露而产生的认知变化。参与者填写了一份综合问卷，并在一年的间隔内接受了两次认知测试。用智力结构测试（IST）测量图形和言语记忆，用FAKT-II和d2测试测量注意力的准确性和持续性。在基线时，根据学校和家庭位置对噪声及其他环境压力源进行建模。用多重填补法处理缺失数据。进行了横断面多层次分析和纵向变化分数分析。在横断面分析中，在家中（L）每增加10分贝道路交通噪声，图形记忆显著降低-0.27（95%CI -0.49，-0.04）个单位。纵向分析显示，在家中（L）每增加10分贝道路交通噪声，基线与随访之间注意力持续性Z分数显著降低-0.13（95%CI -0.25，0.00）。我们的研究表明，家中的道路交通噪声会降低青少年的认知表现。需要更大规模的队列和更长的随访时间来证实这些结果。
