A case study on the exposure-response relationship of sleep disturbance due to road traffic noise - As a case in Japan in the 2020s

Le résumé fourni par la source

A socio-acoustic survey was conducted among residents living along major arterial roads in Kanagawa Prefecture, Japan, to examine the occurrence of sleep disturbances due to road traffic noise. Lnight noise maps was introduced for estimating ranges from 30 dB to 80 dB. We asked the frequency of "difficulty falling asleep," "nocturnal awakenings," "early morning awakenings", "feeling unrefreshed in the morning",and "daytime sleepiness" due to road traffic noise. Cases experiencing any of these items more than three times a week were defined as "highly sleep disturbed (HSD)", and that one or twice a week were defined as "sleep disturbed (SD)", respectively. The exposure response relationships between those and Lnight were examined with the independent variables of noise sensitivity, gender, and age. The results of multiple logistic regression analysis revealed that Lnight, and noise sensitivity had a significant effect on SD, while noise sensitivity significantly affected HSD. We show the results of this study in comparison with previous surveys on sleep disturbances conducted in Japan and other regions.
