Survey Results of a Pilot Sleep Study Near Atlanta International Airport

Aircraft noise can disturb the sleep of residents living near airports. To investigate potential effects of aircraft noise on sleep, recruitment surveys for a pilot field study were mailed to households around Atlanta International Airport. Survey items included questions about sleep quality, sleep disturbance by noise, noise annoyance, coping behaviors, and health. Of 3159 deliverable surveys, 319 were returned (10.1%). Calculated outdoor nighttime aircraft noise (Lnight) was significantly associated with lower sleep quality (poor or fair; odds ratio (OR) = 1.04/decibel (dB); p < 0.05), trouble falling asleep within 30 min ≥1/week (OR = 1.06/dB; p < 0.01), and trouble sleeping due to awakenings ≥1/week (OR = 1.04/dB; p < 0.05). Lnight was also associated with increased prevalence of being highly sleep disturbed (OR = 1.15/dB; p < 0.0001) and highly annoyed (OR = 1.17/dB; p < 0.0001) by aircraft noise. Furthermore Lnight was associated with several coping behaviors. Residents were more likely to report often or always closing their windows (OR = 1.05/dB; p < 0.01), consuming alcohol (OR = 1.10/dB; p < 0.05), using television (OR = 1.05/dB; p < 0.05) and using music (OR = 1.07/dB; p < 0.05) as sleep aids. There was no significant relationship between Lnight and self-reported general health or likelihood of self-reported diagnosis of sleep disorders, heart disease, hypertension or diabetes. Evidence of self-reported adverse effects of aircraft noise on sleep found in this pilot study warrant further investigation in larger, more representative subject cohorts.

Abstract Introduction Nocturnal traffic noise can fragment sleep through cortical arousals and induce self-reported sleep disturbance. Here we present data gathered around Atlanta International Airport in a pilot field study on the effects of aircraft noise on sleep. Methods N=34 subjects participated in a five night in-home study. Every night, subjects recorded noise inside their bedroom, and completed questionnaires the following morning containing items on sleep latency; number of awakenings; sleepiness (Stanford Sleepiness Scale); 11-point scales on sleep quality, tiredness, ease of falling asleep and calmness or restlessness of sleep; and a 5-point scale on sleep disturbance by noise. We analyzed the effect of both the average (LAEq,sleep) and maximum (LAS,max,sleep) aircraft noise level during a subject’s sleep period for each questionnaire outcome in repeated measures multiple regression adjusted for the number of aircraft noise events during sleep, sex, age, and if the window was open or closed. Results A total of 165 sleep questionnaires (97.1% of expected) were completed. Self-reported awakenings increased by n=0.051 per decibel (dB) LAS,max,sleep (p<0.001). An increase in LAS,max,sleep was associated with a significant increase in tiredness (0.118/dB, p=0.005). There was a significant effect of sex on tiredness in the LAEq,sleep model, whereby men were less tired than women. There were no significant effects of LAEq,sleep on any questionnaire outcomes. Conclusion There was some evidence for adverse effects of aircraft noise on self-reported sleep outcomes. Effects were predominantly found for maximum rather than average noise exposure during the sleep period, stressing the importance of individual noise events for sleep. A larger-scale, adequately powered National Sleep Study will be conducted to better understand the observed effects. Support This research was funded by the U.S. Federal Aviation Administration Office of Environment and Energy through ASCENT, the FAA Center of Excellence for Alternative Jet Fuels and the Environment, project 017 through FAA Award Number 13-C-AJE-UPENN-011 under the supervision of Natalia Sizov.

Over Time

There have been many arguments about findings of an increase in noise annoyance over time and a recommendation of stricter limits on aircraft noise levels to protect the health of residents around airports. It is crucial to examine if the established exposure–response relationship is suitable for designing future aircraft noise regulations. This study was focused on identifying changes in response to noise over time by comparing community responses from two surveys conducted in 2008 and 2019 at Tân Sơn Nhất (TSN) international airport. Annoyance was found to significantly reduce in 2019 compared to 2008; however, changes in sleep quality were relatively small. Unexpectedly, a gradual increase in the annoyance due to aircraft noise was not found. Results of multiple regression analysis indicated that differences in the reaction of the residents to noise in the two studies were significantly attributed to nonacoustic factors. Noise sensitivity and dissatisfaction with the living environment (e.g., inconvenience in accessing workplace) considerably affect noise annoyance, whereas noise sensitivity, age, and dissatisfaction with the green environment of living areas affect sleep quality. These findings suggest the fulfillment of desired living environment as effective measures for mitigating noise impacts on residents in the vicinity of busy airports.

Užsienyje yra atlikta nemažai tyrimų, rodančių, kad dėl didėjančių reikalavimų mokykloje ir naujai atsiradusių socialinių interesų, taip pat biologinių pokyčių paaugliai miega nepakankamai ilgai ir kokybiškai. Dėl to nukenčia jų pažangumas mokykloje, didėja psichoaktyvių medžiagų naudojimo rizika ir kita. Užsienyje šia kryptimi atlikta nemažai tyrimų, vis dėlto nedaug yra tyrinėtas miego kokybės ryšys su tyrimų, vertinančių, kaip asmenybės bruožai gali būti susiję su miego kokybe, per miegui nepalankų elgesį, rasti pavyko nedaug, o paauglių tokių tyrimų neradome. Taigi, siekdami įvertinti Lietuvos paauglių miego kokybės rodiklius, asmenybės bruožų ir miego kokybės sąsajas bei kaip asmenybės bruožai yra susiję su įvairia sveikatai nepalankia elgsena, kuri savo ruožtu gali turėti didelę įtaką ir miego kokybei, apklausėme 88 vaikinus ir 124 merginas (amžiaus vidurkis 17,7 metų) iš dviejų Kauno mokyklų. Tyrimui buvo sudarytas klausimynas, skirtas įvertinti įvairius miego kokybės aspektus ir miegui nepalankų elgesį. Asmenybės bruožams tirti buvo naudotas NEO PI-R klausimynas. Rezultatai parodė, kad vaikinų ir merginų neurotizmo bruožas yra susijęs su didesniais sunkumais užmigti ir mažesniu pasitenkinimu nakties poilsiu, kad ir koks būtų elgesys, susijęs su miego kokybe. Merginų grupėje atvirumo patyrimui bruožas yra susijęs su mieguistumu dieną, o ekstraversija ir mažesnis sutariamumas yra susiję su sunkumais užmigti. Ši sąsaja yra veikiama dažnesnio psichoaktyvių medžiagų vartojimo. Vaikinų sąmoningumo bruožas yra susijęs su dažnesniu miegojimu dieną. Ši sąsaja yra veikiama dažnesnio sportavimo. Užsiėmimas atpalaiduojančia veikla prieš miegą merginų grupėje yra susijęs su atvirumo patyrimui ir sąmoningumo bruožais bei su didesniais sunkumais užmigti ir miegojimu dieną. Vaikinų ekstravesija, atvirumas patyrimui ir sutariamumas su miego kokybe bei su miego kokybe susijusiu elgesiu nėra susiję.Pagrindiniai žodžiai: miego kokybė, su miego kokybe susijęs elgesys, paaugliai, asmenybės bruožai, penkių faktorių modelis.The Relationship among Sleep Quality, Sleep-related Behaviour and Personality Traits in Older SchoolchildrenRimantas Vosylis, Aidas Perminas, Rita Žukauskienė SummaryObjectives. Adolescence is a period of various physical, cognitive activities, emotional and social alterations, which need additional bodily resources and naturally good and sufficient sleep for renewing these resources. However, increased requirements in school, new social interests, biological alterations make adolescents’ sleep not sufficiently long and qualitative enough, so achievements at school and the quality of life generally suffer. There are a lot of researches on this topic in foreign countries, but we couldn’t find any in Lithuania. Little research, both in Lithuania and abroad, has been done on personality and sleep quality relations in adolescence and on how personality traits can be related to sleep quality, how this relation can be affected by sleep-related behaviour.Purpose. To evaluate the relationship of personality features to sleep quality and sleep-related behaviour in older schoolchildren. The research involved 88 boys and 124 girls from two Kaunas schools. Methods. A questionnaire was prepared to evaluatesleep quality. It contained 31 questions concerning various sleep quality aspects. Four indices (troubles in falling asleep, night rest satisfaction, daytime fatigue, habit to sleep in the daytime) were selected after a factor analysis. Additionally, 12 questions concerning sleep-related behaviour were asked, from which four indices (use of psychoactive substances, sport, PC games and watching TV, relaxation activity before sleep) were constructed after factor analysis and used in this study. The NEO PI-R questionnaire was used to measure personality traits.Results. In boys and girls, neuroticism is related with the difficulties of falling asleep and less satisfaction with night’s rest independently of sleep-related behaviour. Girls’ openness to experience is related to daytime fatigue, and their extraversion andsmaller agreeableness are related with difficulties of falling asleep, but this association is affected by the use of psychoactive substances. Boys’ conscientiousness is related to daytime sleeping, but this relation is affected by engaging in sport activities. Girls’ engagement in the activities that help relax before sleep is related to their higher conscientiousness, higher agreeableness, more frequent difficulties with falling asleep and daytime sleeping. Boys’ extraversion, openness, agreeableness and sleep quality are not related to each other.Keywords: sleep quality, sleep quality-related behaviour, adolescents, personality traits, five-factor model.

The Relationship

Aircraft noise exposure is a health risk and there is evidence that noise annoyance partly mediates the association between noise exposure and stress-related health risks. Thus, approaches to reduce annoyance may be beneficial for health. Annoyance is influenced by manifold non-acoustic factors and perceiving a fair and trustful relationship between the airport and its residents may be one of them. The distribution of aircraft noise exposure can be regarded as a fairness dilemma: while residents living near an airport may seem to have some advantages, the majority of residents living under certain flight routes or in their immediate proximity suffer from the disadvantages of the airport, especially the noise. Moreover, a dilemma exists between the airport’s beneficial economic impact for a region and the physical and psychological integrity of residents. Aircraft noise exposure through the lens of social justice research can help to improve our understanding of noise annoyance. Research indicates that the fairness perceptions of the parties involved can be enhanced by (a) improving individual cost–benefit ratios, (b) providing a fair procedure for deciding upon the noise distribution, and (c) implementing fair social interaction with residents. Based on the review of evidence from social justice research, we derive recommendations on how fairness aspects can be integrated into aircraft noise management with the purpose of improving the relationship between the airport and its residents, to reduce annoyance, and to enhance the acceptance of local aviation and the airport as a neighbor.

Thermal comfort is crucial in satisfaction and maintaining quality sleep for occupants. In this study, we investigated the comfort temperature in the bedroom at night and sleep quality for Indonesian students during summer and winter. Eighteen male Indonesian students aged 29 ± 4 years participated in this study. The participants had stayed in Japan for about six months. We evaluated the sleep parameters using actigraphy performed during summer and winter. All participants completed the survey regarding thermal sensation, physical conditions, and subjective sleepiness before sleep. The temperature and relative humidity of participants’ bedrooms were also measured. We found that the duration on the bed during winter was significantly longer than that during summer. However, sleeping efficiency during winter was significantly worse than that during summer. The bedroom temperature of the participants was in the range of comfort temperature in Indonesia. With the average bedroom air temperature of 22.2 °C, most of the participants still preferred “warm” and felt “slightly comfortable” during winter. The average comfort temperature each season calculated using the Griffiths method was 28.1 °C during summer and 23.5 °C during winter. In conclusion, differences in adaptive action affect bedroom thermal conditions. Furthermore, habits encourage the sleep performance of Indonesian students.

AbstractPreliminary findings suggest that pets may impact the owner’s sleep. By using data from the Swedish CArdioPulmonary bIoimage Study (SCAPIS) cohort, we aimed to investigate the association of pet ownership with the following self-reported sleep outcomes in 3788 to 4574 participants: (i) achieving the recommended daily sleep duration for adults (i.e., at least 7 h per day); (ii) sleep quality as measured by the Pittsburgh Sleep Quality Index (a score of > 5 indicating poor sleep quality); and (iii) difficulty falling or staying asleep. Sleep metrics were not associated with pet ownership, dog ownership, and dog walking when controlling the logistic regression for possible confounders (e.g., shift work, lack of social interaction, and chronic stress). In contrast, cat ownership was associated with a higher odds ratio of failing to achieve the recommended duration of 7 h of sleep per day (adjusted odds ratio [95% CI]:1.18 [1.02, 1.37] versus non-cat owners). Our findings suggest that certain pet groups might have a more significant impact on the owner’s sleep than others. As the observed association between cat ownership and short sleep duration might be a chance finding, this observation should be seen as hypothesis-generating only.

This study aimed to investigate prolonged screen time and using electronic devices before sleep and their associated factors in elderly people in Shaanxi province of China. We conducted a cross-sectional study among 2647 elderly participants aged 60–88 years. Data were collected through questionnaires. Demographic characteristics, screen time, using electronic devices before sleep, health status, lifestyles, sleep quality, and other associated factors were investigated. Logistic regression analysis was used to analyze the relationship between the associated factors of screen time and using electronic devices before sleep. The crude odds ratio (cOR) and adjusted odds ratio (aOR) and their 95% confidence intervals (CI) were calculated. A total of 1784 subjects completed the questionnaire. There were 6.89% participants with prolonged screen time and 13.45% using electronic devices before sleep frequently. Prolonged screen time was associated with personal monthly income (aOR = 1.205, p = 0.001), number of household residents (aOR = 0.860, p = 0.010), rural residents (aOR = 0.617, p = 0.038), and regular drinkers (aOR = 2.889, p < 0.001). Using electronic devices before sleep was associated with being female (aOR = 0.657, p = 0.007), family monthly income (aOR = 0.866, p = 0.002), being an occasional drinker (aOR = 1.891, p = 0.005), and self-reported sleep quality (aOR = 1.593, p = 0.007). In conclusion, several factors related to screen time or using electronic devices before sleep were identified. Only being a drinker was a common associated factor for both screen time and using electronic devices before sleep.

Abstract Background Sleep disturbances are common in individuals with post traumatic stress disorder (PTSD). However, little is known about how daily variation in sleep characteristics is related to PTSD. This study examined the night-to-night and weekday versus weekend variation in sleep duration, sleep quality, trouble falling asleep, and difficulty staying asleep in individuals with and without PTSD. Methods Participants (N = 157; 80 with PTSD, 77 without PTSD) completed daily self-reports of their nighttime sleep characteristics for 15 consecutive days. Linear mixed models were used to examine the associations between the 7 days of the week and weekday versus weekend variation in sleep characteristics and PTSD. Results Individuals with PTSD reported shorter sleep duration, lower sleep quality, more trouble falling asleep, and more difficulty staying asleep than individuals without PTSD. The pattern of change across the week and between weekdays and weekends was different between those with and without PTSD for sleep quality and trouble falling asleep. Among those with PTSD, sleep duration, sleep quality, and trouble falling asleep differed across the 7 days of the week and showed differences between weekdays and weekends. For those without PTSD, only sleep duration differed across the 7 days of the week and showed differences between weekdays and weekends. Neither group showed 7 days of the week nor weekday versus weekend differences in difficulty staying asleep. Conclusions On average those with PTSD had shorter sleep duration, poorer sleep quality, and greater trouble falling and staying asleep. In particular, the day of week variation in sleep quality and trouble falling asleep specifically distinguishes those with PTSD from those without PTSD. Our findings suggest that clinical care might be improved by assessments of sleep patterns and disturbances across at least a week, including weekdays and weekends. Future studies should explore the mechanisms related to the patterns of sleep disturbance among those with PTSD.
