Abstract
Background: Nighttime aircraft noise may affect people’s sleep, yet large-scale evidence using objective and subjective measures remains limited. // Objective: Our aim was to investigate associations between nighttime aircraft noise exposure and objectively measured sleep disturbance using a large UK cohort. // Methods: We used data from 105,770 UK Biobank cohort participants exposed and unexposed to aircraft noise who lived in 44 local authority districts near 4 international airports in England. We used a generalized linear regression model to examine cross-sectional associations between aircraft noise Lnight (23:00 hours–07:00 hours) and 7-d actimetric measures collected 2013–2015 (n= 22,102). We also used Logit and generalized estimating equations models to examine associations between Lnight and self-reported sleep measures at enrollment (2006–2010) and follow-up (2012–2013). This approach allowed us to compare and contrast the results and support potential future meta-analyses on noise-related sleep disturbance. // Results: Cross-sectional analyses of actimetric data suggested sleep disturbance associated with Lnight, showing higher level of movements during the least active continuous 8-h time period [b: 0.12 milligravitational units; 95% confidence interval (CI): 0.013, 0.23]. We also saw disrupted sleep– wake cycles as indicated by index scores of lower relative amplitude (b: −0:006; 95% CI: −0:007, −0:005), poorer interdaily stability (b: −0:010; 95% CI: −0:014, −0:006), and greater intradaily variability (b: 0.021; 95% CI: 0.019, 0.023), comparing Lnight ≥55 dB with <45 dB. Repeated crosssectional analyses found a 52% higher odds of more frequent daytime dozing [odds ratio (OR) = 1:52; 95% CI: 1.32, 1.75] for Lnight ≥55 dB in comparison with <45 dB, whereas the likelihood for more frequent sleeplessness was more uncertain (OR = 1:13; 95% CI: 0.92, 1.39). Higher effect sizes were seen in preidentified vulnerable groups, including individuals >65 y of age and those with diabetes or dementia. // Conclusion: Individuals exposed to higher levels of aircraft noise experienced objectively higher levels of sleep disturbance and changes in sleep– wake cycle.
