Healthy from the Start: Co-Designing Sleep, Nutrition and Physical Activity Resources for Young Shiftworkers-Novel Implementation and Evaluation.

INTRODUCTION: The increasing prevalence of shiftwork among young adults poses significant health risks, primarily due to its disruptive effects on sleep, nutrition and physical activity. Addressing these risks necessitates the development of tailored, evidence-based resources to support these key health behaviours. Participatory research approaches, engaging those with relevant lived experience (i.e., co-design) are a novel and effective approach in developing these resources. As such, the aim of the present study was to explore whether sleep, nutrition and physical activity resources for young shiftworkers could be developed using participatory, co-design approaches and how co-designers would rate both the approaches used and the resulting resources. METHODS: A participatory approach engaged co-designers (young, experienced or previous shiftworkers; workplace health and safety specialists; science communicators and academic experts) to complete 2-3 online questionnaires and participate in 1-2 online workshops, to co-design sleep, nutrition and physical activity resources for young shiftworkers. Following resource development, co-designers assessed both the participatory approach and the resulting resources, through an online questionnaire, which included the Public and Patient Engagement Evaluation Tool (PPEET). RESULTS: Co-designers (n = 48) participated in the development of sleep, nutrition and physical activity resources for young shiftworkers. Co-designers evaluated the participatory approach positively, with a mean rating across all PPEET items of 4.7 (±0.2) on a 5-point Likert scale. Co-designers also provided positive ratings for the resources, with the majority (91.7%) either agreeing or strongly agreeing that they were user-friendly, valuable and informative for young shiftworkers and would serve as a credible source of health information. CONCLUSION: By adopting a novel participatory approach, we successfully co-designed sleep, nutrition and physical activity resources for young shiftworkers. Participatory approaches, including co-design, should be considered when developing health interventions for shiftworkers, given the value of embedding lived experience to address their unique lifestyle challenges. PATIENT OR PUBLIC CONTRIBUTION: Co-designers and/or people with relevant lived experience were involved in all project activities: conceptualisation, design, recruitment, data collection, data analysis, knowledge translation and output generation.

Improving sleep health in paramedics through an app-based intervention: a randomised waitlist control pilot trial.

BACKGROUND: Due to work commitments, shiftworkers often obtain inadequate sleep, consequently experiencing negative health, wellbeing, and safety outcomes. Given shiftworkers may have limited control over their work commitments, lifestyle and environmental factors within their control may present an intervention opportunity. However, such interventions require tailoring to ensure applicability for this sleep-vulnerable population. METHODS: A randomised waitlist control pilot trial investigated the effectiveness of mobile health application Sleepfit, which delivered a tailored sleep health intervention aimed at improving sleep health and sleep hygiene outcomes amongst paramedic shiftworkers. Outcome measures of self-reported sleep health (sleep need, duration, and quality, fatigue, Insomnia Severity Index, Fatigue Severity Scale, and Epworth Sleepiness Scale scores) and sleep hygiene (Sleep Hygiene Index score) were collected at baseline, post-intervention, and 3-month follow-up. RESULTS: Fifty-eight paramedics (aged 33.4 ± 8.0 years; 50% male) were recruited, and trialed Sleepfit for a 14-day intervention period between August 2021-January 2022. For all participants, there was a significant reduction in Insomnia Severity Index and Sleep Hygiene index scores after intervention engagement. Regression models demonstrated no significant intervention effect on sleep health or sleep hygiene outcomes (intervention versus waitlist control group). A high study drop-out rate (91.4%) prevented assessment of outcomes at 3-month follow-up. CONCLUSIONS: Pilot trial findings demonstrate that Sleepfit may elicit improvements in sleep health and sleep hygiene outcomes amongst paramedic shiftworkers. However, low enrolment and retention means that findings should be interpreted with caution, further highlighting potential engagement challenges, especially among paramedics who are particularly in need of support for improved sleep. TRIAL REGISTRATION: Prospectively registered with the Australian New Zealand Clinical Trial Registry 24/01/2020 (reference no. ACTRN12620000059965).

Even a Mild Sleep Restriction Can Impact Daytime Functioning in Children with ADHD and Their Typically Developing Peers.

OBJECTIVES/BACKGROUND: Correlational studies show that short sleep is associated with negative daytime outcomes in school-aged children, but there are few experimental sleep manipulation studies to assess whether this is a causal relation. The aim of this study was to determine the impact of mild, cumulative sleep restriction on daytime functioning of typically developing (TD) children and children with attention-deficit/hyperactivity disorder (ADHD). PARTICIPANTS: A total of 36 school-aged children (n = 18 TD; n = 18 ADHD), aged 6-11 years participated. METHODS: Children participated in two sleep conditions (order counter-balanced). The Restricted condition required a 1 h reduction of time in bed for one week, and the Controlled Typical condition was based on participant's average baseline sleep. At the end of each condition, participants attended the sleep lab for overnight polysomnography and daytime functioning assessments. RESULTS: Children successfully reduced time in bed by ~1 h. Due to compensatory changes, total sleep time (TST) was reduced by only ~20 min, as children fell asleep faster and spent less time awake after sleep onset during the Restricted compared to Controlled Typical condition. Many daytime functions were not affected by this very mild sleep restriction, however, both groups showed significant changes in performance on an objective attention task and on a parent-rated emotional lability measure after six nights of minimal reductions in TST. There were no significant differences between groups. CONCLUSIONS: Results suggest that a very mild sleep restriction can affect children's attention and emotional regulation, even with evidence of compensatory sleep mechanisms.

Healthy sleep for healthy schools: A pilot study of a sleep education resource to improve adolescent sleep.

ISSUE ADDRESSED: Insufficient sleep and unhealthy sleep practices in adolescents are associated with significant health risks. Sleep education programs in schools aim to improve sleep behaviour. A new eLearning sleep education program, Healthy Sleep for Healthy Schools (HS4HS), was developed focused on these goals and is distinguishable from other sleep education programs because it is delivered by teachers, making it more sustainable and adaptable for schools. We aimed to evaluate if HS4HS would improve student sleep knowledge, healthy sleep practices, sleep duration and reduce sleepiness. We also aimed to understand if this intervention could be successfully implemented by trained teachers. METHODS: Teachers trained in sleep delivered HS4HS to 64 South Australian students in year 9 (aged 13-14 years) over 6 weeks during regular school curriculum. A sleep education survey assessing sleep patterns (such as healthy sleep practices, time in bed and sleepiness), and a sleep knowledge questionnaire was completed pre- and post-HS4HS delivery. Evaluations were also completed by teachers. RESULTS: Sleep knowledge and healthy sleep practices significantly improved post intervention. Time in bed on both school days and weekends increased slightly and sleepiness decreased slightly, but these changes were not statistically significant. Teachers found the program useful, comprehensive and easy to incorporate into their curricula. CONCLUSIONS: After short training, teachers can deliver sleep education during class and improve sleep practices in their students. This suggests that this program may offer potential as an effective and useful resource for teachers wanting to include sleep health in their curriculum. SO WHAT?: Sleep is the foundation of good health and teachers can promote and integrate sleep education into their curricula for the first time with this online teacher focussed program, which has the potential to be a sustainable sleep health promotion resource.

The need for sleep and circadian education in Australian high schools: incidental results from a survey of university students.

ISSUE ADDRESSED: To describe the need for high school sleep education from the perspective of undergraduate university students. METHODS: Undergraduate students who completed an online course on sleep and circadian health were surveyed 6 months after course completion. Students were asked whether a similar course would have benefited them as high school students, and about the need for sleep education in high schools. Thematic analysis of this qualitative data was carried out. RESULTS: Eighty-nine students who had attended 71 unique high schools provided responses. Eight-one per cent thought they would have benefitted from a similar course during high school and identified domains of sleep knowledge particularly relevant to high school students. They cited environmental barriers to healthy sleep present during high school and believed that sleep education could improve students' lifestyle, sleep and performance. Nineteen per cent of students said they would not have benefited, because they perceived sleeping patterns during high school to be nonmodifiable or believed that previous sleep education was sufficient. Of the respondents who did not think students would benefit, 53% would still tell their high school principal that there was a need for sleep education. CONCLUSIONS: The findings support the need for engaging sleep education for high school students. Future studies should examine the perspectives of students in high school directly, rather than undergraduate students who have already shown an interest in sleep health. SO WHAT?: Sleep health is missing from the Australian school curriculum. Online courses may be an engaging method of promoting sleep and circadian health to high school students.

Usability of an eHealth sleep education intervention for university students.

Background: It has been estimated that more than one-third of university students suffer from insomnia. Few accessible eHealth sleep education programmes exist for university students and of the ones that do exist, fewer were developed using a user-centred approach, which allows for student input to be systematically collected and utilized to provide students with a programme that they consider to be easy to use and implement and to be effective. Better Nights, Better Days-Youth (BNBD-Youth) is a four-session eHealth sleep education programme designed for youth but previously only evaluated in younger adolescents (ages 14-18 years). Aims: The purpose of this study is to evaluate the usability of the BNBD-Youth programme with university students using Morville's User Experience Honeycomb framework to determine if this programme would meet the needs of university students and if so what modifications would be needed. Methods: Canadian undergraduate students (n = 46) completed the BNBD-Youth programme. Students completed online usability questionnaires based on the seven dimensions of Morville's User Experience Honeycomb (i.e. useful, usable, valuable, credible, desirable, accessible and findable) after each session and after completion of the programme. Open- and closed-ended questions were used to obtain both quantitative and qualitative responses. Results: Average quantitative ratings were positive across user experience dimensions, ranging from 3.43 to 4.46 (out of 5). Qualitative responses indicated overall positive experiences with the programme. The only constructive feedback that met the criteria for revising the programme was to include more interactive features in Session 4. Conclusions: This study demonstrates that university students found BNBD-Youth to be a usable programme for older youth. Demonstrating usability is an essential step in developing a programme with a user-centred design that university students will want to use in the future. Once the BNBD-Youth programme is revised to create the BNBD-University (BNBD-Uni) programme, additional usability and effectiveness testing will be conducted.

Healthy sleep practices for shift workers: consensus sleep hygiene guidelines using a Delphi methodology.

STUDY OBJECTIVES: The unique requirements of shift work, such as sleeping and working at variable times, mean that current sleep hygiene guidelines may be inappropriate for shift workers. Current guidelines may also contradict fatigue management advice (e.g. advising against daytime napping). The present study utilized a Delphi methodology to determine expert opinion regarding the applicability of current guidelines for shift workers, the appropriateness of the term "sleep hygiene," and develop tailored guidelines for shift workers. METHODS: The research team reviewed current guidelines and existing evidence to draft tailored guidelines. Seventeen individual guidelines, covering sleep scheduling, napping, sleep environment, bedtime routine, substances, light exposure, diet, and exercise were drafted. Experts from sleep, shift work, and occupational health fields (n = 155) were invited to review the draft guidelines using a Delphi methodology. In each round, experts voted on individual guidelines, with 70% agreement considered consensus. Where consensus was not reached, written feedback from experts was discussed and incorporated into subsequent iterations. RESULTS: Of the experts invited, 68 (44%) agreed to participate, with 55 (35%) completing the third (final) round. Most experts (84%) agreed that tailored guidelines were required for shift workers. Consensus was reached on all guidelines after three rounds. One additional guideline (sleep inertia) and an introductory statement were developed, resulting in a final set of 18 individual guidelines, termed "healthy sleep practices for shift workers." CONCLUSIONS: This is the first study to develop tailored sleep hygiene guidelines for shift workers. Future research should investigate the acceptability and effectiveness of these guidelines amongst shift workers.

Sleep hygiene in paramedics: What do they know, and what do they do?

OBJECTIVES: Shift workers routinely obtain inadequate sleep, which has major health and well-being consequences. Sleep hygiene describes a range of behaviors, lifestyle and environmental factors that can support optimal sleep. To date, limited research has examined sleep hygiene in shift workers. This study aimed to 1) assess the knowledge and understanding of sleep hygiene amongst shift working paramedics, as well as the perceived impact on sleep, and 2) investigate paramedics engagement with sleep hygiene practices. STUDY DESIGN: Participants completed an online, cross-sectional survey. PARTICIPANTS: Queensland Ambulance Service paramedics (n = 184) who work shift work. MEASURES: The online survey included questions from the Standard Shiftwork Index and Sleep Hygiene Index. RESULTS: Most participants reported little or no understanding or knowledge of "sleep hygiene" as a concept. Participants reported that sleep scheduling and bedroom environment (temperature, light, and noise) were the most impactful on sleep. Few participants reported nicotine and alcohol consumption, or daytime napping, whereas caffeine consumption and mentally-stimulating bedtime activities were more common. Participants who were young, single, and worked all shift types (day, afternoon, and night) as part of their regular rosters, demonstrated less knowledge regarding sleep hygiene, and were more likely to be exhibiting poor sleep hygiene engagement. CONCLUSIONS: Paramedics demonstrated a limited level of understanding of sleep hygiene as a concept, and varied knowledge about the impacts of individual sleep hygiene factors. Further, paramedics demonstrated varied engagement with individual sleep hygiene practices. Future research should focus on the development of sleep hygiene interventions to optimize sleep in paramedics.

Focus Groups to Inform User-Centered Development of an eHealth Sleep Intervention for Adolescents: Perspectives of Youth with Insomnia Symptoms, with and without Pain.

INTRODUCTION: Adolescence is a developmental stage that often coincides with increasing sleep problems. Focus groups were conducted to inform development of an adolescent eHealth sleep intervention by exploring opinions about (1) healthy sleep practices, and (2) using an eHealth intervention. METHODS: Adolescents 14-18 years old experiencing symptoms of insomnia based on the Insomnia Sleep Index, with and without recurrent pain, and associated stakeholders (i.e., parents, school personnel, and health care providers) were recruited. Across six online focus groups, 24 adolescents with insomnia participated (14 pain-free, 10 with recurrent pain; 10 male, 14 female). Across seven online focus groups, 22 stakeholders participated, including 8 parents, 9 school professionals, and 5 health care providers (10 male, 8 female). Using a content analysis, subthemes were induced from transcripts. RESULTS: Most healthy sleep practices were perceived as reasonable for adolescents to implement, except avoiding technology before bed and using bedrooms only for sleep. Three primary barriers to sleep practices were identified, including a variable schedule due to lifestyle factors, technology at night, and academics interfering with sleep, and only in the pain group, the barrier related to pain was identified. Content addressing adolescent-specific barriers was considered important to include in a sleep intervention. Desirable eHealth components included interactive features, videos, audio, and pictures to present information. A common barrier to using an eHealth sleep intervention was the program feeling too academic, with accessibility of the sleep information and strategies as a common facilitator. CONCLUSIONS: This research represents the first step in a user-centered approach to developing an adolescent eHealth sleep intervention. These results provide insights from a range of perspectives on guiding adolescents to follow healthy sleep practices. Next, these findings will be integrated in the development of an eHealth intervention for adolescents with and without recurrent pain.

Predicting attitudes towards easing COVID-19 restrictions in the United States of America: The role of health concerns, demographic, political, and individual difference factors.

Despite rising cases of COVID-19 in the United States of America, several states are easing restrictions (e.g., relaxing physical distancing requirements, reopening businesses) that were imposed to limit community transmission of the virus. Individuals hold differing opinions regarding whether restrictions should continue to be imposed or lifted, evidenced, for example, by debate and protests regarding reopening of businesses and venues. Health and social psychological research suggest that perceptions of COVID-19related risk, experiences of the virus, and individual difference factors can help explain individuals' attitudes towards health initiatives and their tendency to be persuaded towards a specific course of action. The purpose of this study was to investigate what factors influence support or opposition to easing COVID-19-related restrictions. A sample of 350 United States citizens, responding to an anonymous survey, were asked about the extent to which they support/oppose easing of COVID-19-related restrictions, both generally and in relation to specific restrictions. Respondents completed measures of their experiences of COVID-19, individual difference factors, and demographic variables, including political affiliation and degree of social and economic conservatism. In a series of regression analyses, significant demographic predictors of support or opposition for easing restrictions were gender, age, ethnicity, and education, with political affiliation and degree of social and economic conservatism also predicting attitudes. Experiences related to COVID-19 that predicted attitudes were concerns for self and family, perceptions of threat posed by the virus, perceived ability to adhere to restrictions, willingness to take government direction, and belief in COVID-19-related conspiracy theories. At an individual differences level, uncertainty avoidance, collectivism, long-term orientation, masculinity, empathic concern, personal distress, reactance, and general conspiracy theory beliefs all significantly precited attitudes to easing restrictions. Understanding the factors that help explain attitudes towards COVID-19 restrictions can inform how best to position health messaging and initiatives going forward, particularly as states or countries open borders.

Does knowledge of sleep hygiene recommendations match behaviour in Australian shift workers? A cross-sectional study.

OBJECTIVES: Shiftworkers routinely obtain inadequate sleep, which has major health consequences. Sleep hygiene describes a range of behaviours, lifestyle and environmental factors that can improve sleep. To date, limited research has examined sleep hygiene in shiftworkers. This study aimed to assess the sociodemographic and behavioural correlates of sleep hygiene knowledge and engagement with sleep hygiene practices in Australian shiftworkers. STUDY DESIGN: An online, cross-sectional survey. SETTING AND PARTICIPANTS: Australian adults from across multiple industries (n=588) who work shift work. MEASURES: The online survey included questions regarding sleep hygiene knowledge and questions from modified versions of the Pittsburgh Sleep Quality Index and Sleep Hygiene Index. RESULTS: Of the 588 participants, 52.9% reported having heard of 'sleep hygiene'. Of these participants, 77.5% reported understanding the term moderately, extremely or very well. Engagement with each sleep hygiene practice was varied. Common sleep hygiene practices were controlling the bedroom environment (eg, a cool, dark and quiet bedroom). Less common practices were avoiding light as bedtime approaches. Logistic regressions revealed that shiftworkers who had heard of sleep hygiene were more likely to engage in sleep hygiene practices and had better sleep quality compared with those who had not heard of sleep hygiene. Increased engagement in sleep hygiene practices did not predict the likelihood of individuals reporting better sleep quality. CONCLUSIONS: Shiftworkers demonstrated varied knowledge, understanding and engagement with individual sleep hygiene practices. Future research should focus on the development of sleep hygiene interventions that accommodate the unique challenges of shift work to optimise sleep.

Update on school-based sleep education programs: how far have we come and what has Australia contributed to the field?

OBJECTIVE: School-based sleep education programs help to promote sleep health information to many children and adolescents. The aim of this systematic review was to identify and describe school-based sleep education programs, to update previous reviews and identify recent advances and improvements in this field worldwide. METHODS: Four electronic databases were searched. Eligibility criteria included children aged 5-18 years, sleep education intervention conducted in a school setting, and at least one pre-post-measure of a sleep variable. RESULTS: A total of 32 articles met eligibility criteria with Australian sleep researchers constituting âˆ¼ one quarter of these studies. Studies dated from 2007 to 2020 with sample sizes ranging from 9 to 3713 students. The majority of participants were high school students and predominantly female. Education programs generally took 4-6 weeks and content was consistent across studies. Overall, exposure to sleep education increased sleep knowledge, however changes in sleep behaviour variables and secondary outcome variables (eg, mental health; cognitive function; sleep hygiene practices) presented varied results. Studies conducted since 2015 were more likely to be randomised controlled trials and to include more interactive, online designs utilising innovative content such as mindfulness. CONCLUSIONS: An exponential growth in school sleep education programs was identified since 2016. Future studies should consider utilising objective sleep measures, longer-term follow-ups, innovative delivery methods, and stronger attempts at implementing a knowledge-to-action approach for more sustainable programs.

Impact of an Online Sleep and Circadian Education Program on University Students' Sleep Knowledge, Attitudes, and Behaviours.

University students consistently report poor sleep. We conducted a before-and-after study to evaluate the impact of an online 10-week course on undergraduate students' sleep knowledge, attitudes, and behaviours at 6-month follow-up. Data were collected via baseline course surveys (August-September 2020) and follow-up surveys distributed via email (February-March 2021). n = 212 students completed baseline surveys and n = 75 (35%) completed follow-up. Students retained to follow-up possessed higher baseline sleep knowledge and received higher course grades. At the 6-month follow-up, sleep knowledge had increased (mean score out of 5: 3.0 vs. 4.2, p < 0.001). At baseline, 85% of students aimed to increase their sleep knowledge and 83% aimed to improve their sleep. At follow-up, 91% reported being more knowledgeable and 37% reported improved sleep. A novel Stages of Change item revealed that 53% of students' attitudes towards their sleep behaviours had changed from baseline. There was a reduction in sleep latency at follow-up (mean 33.3 vs. 25.6 min, p = 0.015), but no change in the total Pittsburgh Sleep Quality Index score. In summary, completion of an online course led to increased sleep and circadian knowledge and changed sleep attitudes, with no meaningful change in sleep behaviours. Future interventions should consider components of behavioural change that go beyond the knowledge-attitudes-behaviour continuum.

Jet-Lag Countermeasures Used by International Business Travelers.

INTRODUCTION: Research has highlighted the significant impact that jet lag can have upon performance, health, and safety. International business travelers have an important role in economic growth; however, there is a lack of research investigating jet lag and jet-lag management in international business travelers. This study aimed to investigate international business travelers use of jet-lag countermeasures. METHODS: International business travelers from Australia (N = 107) participated in a survey examining use of jet-lag countermeasures (pharmacological and nonpharmacological). Chi-squared tests were conducted examining the association between duration of stay and traveling experience on jet-lag countermeasure use. RESULTS: Most subjects had traveled for business for less than 15 yr and 57% reported taking between 14 trips annually. Durations of stay averaged 10 d (SD 13 d). Nonpharmacological countermeasure use was high. Pharmacological countermeasure use was less common. There were no significant associations between duration of stay and countermeasure implementation. Travel experience was only associated with nonpharmacological countermeasures after arrival home. CONCLUSION: Education programs delivered through businesses would be beneficial for providing information on jet lag, its implications, and recommended countermeasures to travelers.

Sleep Variables as Predictors of Treatment Effectiveness and Side Effects of Stimulant Medication in Newly Diagnosed Children with Attention-Deficit/Hyperactivity Disorder.

OBJECTIVE: There is a growing body of research on the impact of stimulant medication on sleep in children with attention-deficit/hyperactivity disorder (ADHD). Negative sleep side effects are a common reason for nonadherence or for discontinuing a course of treatment. However, there is no published evidence as to whether pretreatment sleep can predict responses to treatment and the emergence of side effects. METHOD: In this study, baseline sleep variables were used to predict therapeutic effect (i.e., reduction of ADHD symptoms) and side effects (both sleep and global side effects) in a sample of newly diagnosed, medication-naive children (n = 50). RESULTS: The results of hierarchical regression analysis showed that parent-reported shorter sleep duration before medication treatment significantly predicted better response to treatment, independent of pretreatment ADHD symptoms. Baseline sleep features did not significantly predict global (nonsleep) side effects but did predict increased sleep side effects during treatment. CONCLUSION: These results indicate that baseline sleep variables may be helpful in predicting therapeutic response to medication and sleep disturbance as a side effect of stimulant medication.

Considering the relationship between sleep and empathy and compassion in mental health nurses: It's time.

Sleep plays a critical role in overall health, well-being, and daytime functioning. Provision of 24-hour care means that nurses undertake shift work and therefore have been found to commonly not get the recommended amount of sleep, resulting in sleep deprivation. Research to date has focused on how sleep deprivation impacts their cognitive performance (e.g., reaction time, memory consolidation); however, less considered is how nurses' sleep impacts on their ability to understand and provide emotional care to consumers. In this paper, we examine how sleep may influence nurses' ability to empathize and provide compassionate care, both of which are fundamental aspects of their work. We begin by considering the unique challenges nurses face as shift workers and the impact of sleep on physical and psychological functioning. We examine how empathy and compassion drive nurses' attempts to understand consumers' perspectives and experiences and motivate them to want to help those in their care. Work directly investigating the relationship between sleep and these processes indicates emotional recognition and experience are hampered by poor sleep, with greater compassion towards oneself or from others associated with better sleep. Much of this work has, however, been conducted outside of the nursing or health professional space. We discuss issues that need to be addressed in order to move understanding forward regarding how sleep impacts on mental health nurses' empathy and compassion, as well as how an understanding of the sleep-empathy/compassion link should be an important priority for nurse education and well-being.

Sleep hygiene in paramedics: What do they know and what do they do?

OBJECTIVES: Shift workers routinely obtain inadequate sleep, which has major health and wellbeing consequences. Sleep hygiene describes a range of behaviours, lifestyle and environmental factors that can support optimal sleep. To date, limited research has examined sleep hygiene in shift workers. This study aimed to 1) assess the knowledge and understanding of sleep hygiene amongst shift working paramedics, as well as its perceived impact on sleep, and 2) investigate paramedics' engagement with sleep hygiene practices. STUDY DESIGN: Participants completed an online, cross-sectional survey. PARTICIPANTS: Queensland Ambulance Service paramedics (n = 184) who engage in shift work. MEASURES: The online survey included questions from the Standard Shiftwork Index and Sleep Hygiene Index. RESULTS: Most participants reported little or no understanding or knowledge of 'sleep hygiene' as a concept. Participants reported that sleep scheduling and bedroom environment (temperature, light, and noise) were the most impactful on sleep. Few participants reported nicotine and alcohol consumption, or daytime napping, whereas caffeine consumption and mentally-stimulating bedtime activities were more common. Participants who were young, single, and worked varying shift types (day, afternoon, and night) as part of their regular rosters demonstrated less knowledge regarding sleep hygiene, and were more likely to be exhibiting poor sleep hygiene engagement. CONCLUSIONS: Paramedics demonstrated a limited level of understanding of sleep hygiene as a concept, and varied knowledge about the impacts of individual sleep hygiene factors. Further, paramedics demonstrated varied engagement with individual sleep hygiene practices. Future research should focus on the development of sleep hygiene interventions to optimise sleep in paramedics.

Cognition and objectively measured sleep duration in children: a systematic review and meta-analysis.

BACKGROUND: Sleep recommendations are widely used to guide communities on children's sleep needs. Following recent adjustments to guidelines by the National Sleep Foundation and the subsequent consensus statement by the American Academy of Sleep Medicine, we undertook a systematic literature search to evaluate the current evidence regarding relationships between objectively measured sleep duration and cognitive function in children aged 5 to 13 years. METHODS: Cognitive function included measures of memory, attention, processing speed, and intelligence in children aged 5 to 13 years. Keyword searches of 7 databases to December 2016 found 23 meeting inclusion criteria from 137 full articles reviewed, 19 of which were suitable for meta-analysis. RESULTS: A significant effect (r = .06) was found between sleep duration and cognition, suggesting that longer sleep durations were associated with better cognitive functioning. Analyses of different cognitive domains revealed that full/verbal IQ was significantly associated with sleep loss, but memory, fluid IQ, processing speed and attention were not. Comparison of study sleep durations with current sleep recommendations showed that most children studied had sleep durations that were not within the range of recommended sleep. As such, the true effect of sleep loss on cognitive function may be obscured in these samples, as most children were sleep restricted. CONCLUSIONS: Future research using more rigorous experimental methodologies is needed to properly elucidate the relationship between sleep duration and cognition in this age group.

Evaluation of an Internet-Based Behavioral Intervention to Improve Psychosocial Health Outcomes in Children With Insomnia (Better Nights, Better Days): Protocol for a Randomized Controlled Trial.

BACKGROUND: Up to 25% of 1- to 10-year-old children experience insomnia (ie, resisting bedtime, trouble falling asleep, night awakenings, and waking too early in the morning). Insomnia can be associated with excessive daytime sleepiness and negative effects on daytime functioning across multiple domains (eg, behavior, mood, attention, and learning). Despite robust evidence supporting the effectiveness of behavioral treatments for insomnia in children, very few children with insomnia receive these treatments, primarily due to a shortage of available treatment resources. OBJECTIVE: The Better Nights, Better Days (BNBD) internet-based program provides a readily accessible electronic health (eHealth) intervention to support parents in providing evidence-based care for insomnia in typically developing children. The purpose of the randomized controlled trial (RCT) is to evaluate the effectiveness of BNBD in treating insomnia in children aged between 1 and 10 years. METHODS: BNBD is a fully automated program, developed based on evidence-based interventions previously tested by the investigators, as well as on the extant literature on this topic. We describe the 2-arm RCT in which participants (500 primary caregivers of children with insomnia residing in Canada) are assigned to intervention or usual care. RESULTS: The effects of this behavioral sleep eHealth intervention will be assessed at 4 and 8 months postrandomization. Assessment includes both sleep (actigraphy, sleep diary) and daytime functioning of the children and daytime functioning of their parents. Results will be reported using the standards set out in the Consolidated Standards of Reporting Trials statement. CONCLUSIONS: If the intervention is supported by the results of the RCT, we plan to commercialize this program so that it is sustainable and available at a low cost to all families with internet access.

Establishing normal values for pediatric nighttime sleep measured by actigraphy: a systematic review and meta-analysis.

Background: Despite the widespread use of actigraphy in pediatric sleep studies, there are currently no age-related normative data. Objectives: To systematically review the literature, calculate pooled mean estimates of actigraphy-derived pediatric nighttime sleep variables and to examine the magnitude of change with age. Methods: A systematic search was performed across eight databases of studies that included at least one actigraphy sleep variable from healthy children aged 0-18 years. Data suitable for meta-analysis were confined to ages 3-18 years with seven actigraphy variables analyzed using random effects meta-analysis and meta-regression performed using age as a covariate. Results: In total, 1334 articles did not meet inclusion criteria; 87 had data suitable for review and 79 were suitable for meta-analysis. Pooled mean estimates for overnight sleep duration declined from 9.68 hours (3-5 years age band) to 8.98, 8.85, 8.05, and 7.4 for age bands 6-8, 9-11, 12-14, and 15-18 years, respectively. For continuous data, the best-fit (R2 = 0.74) equation for hours over the 0-18 years age range was 9.02 - 1.04 × [(age/10)^2 - 0.83]. There was a significant curvilinear association between both sleep onset and offset with age (p < .001). Sleep latency was stable at 19.4 min per night. There were significant differences among the older age groups between weekday and weekend/nonschool days (18 studies). Total sleep time in 15-18 years old was 56 min longer, and sleep onset and offset almost 1 and 2 hours later, respectively, on weekend or nonschool days. Conclusion: These normative values have potential application to assist the interpretation of actigraphy measures from nighttime recordings across the pediatric age range, and aid future research.
