School closure during the coronavirus disease 2019 (COVID-19) pandemic - Impact on children's sleep

School-aged children's movement behaviours and subjective health complaints in Japan: a cross-sectional study during COVID-19 pandemic-related school closures and after school reopenings

BACKGROUND

Social restrictions associated with the COVID-19 pandemic have altered children's movement behaviours and impacted their mental health. However, the influence of social restrictions on subjective health complaints remains inadequately understood. This study compared adherence to 24-hour movement behaviour guidelines and the prevalence of subjective health complaints during school closure and one year after reopening. We also examined how combinations of adherence to movement behaviour recommendations relate to subjective health complaints.

METHODS

A repeated cross-sectional survey was conducted at two points. The first survey in May 2020 included 1535 (766 boys and 769 girls) participants during school closures, while the second survey from May to July 2021 involved 1125 (583 boys and 542 girls) participants one year after school reopening. The questionnaire covered socio-demographics, physical activity, screen time, sleep, and subjective health complaints. Differences between periods were analysed using chi-square tests. Logistic regression models assessed the association between adherence to guidelines and subjective health complaints.

RESULTS

During school closure, children were more likely to meet 'only sleep' recommendations and have irritability and lethargy symptoms. Irrespective of sex, those adhering to two or all three recommendations (excluding physical activity and screen time) had a lower risk of symptoms related to physical and mental pain, fatigue, irritability, and lethargy as compared to those who met none of the recommendations.

CONCLUSIONS

Children should meet at least one physical activity or screen time recommendation in addition to sleep recommendations for subjective health. Strategies considering the priority of each movement behaviour are crucial, even during abnormal situations, such as pandemic-related social restrictions. This study offers insightful findings concerning children's mental health issues during unprecedented and massive disasters or crises.

Associations Between Changes in 24-Hour Movement Behaviors in Children and Adolescents During the COVID-19 Pandemic: A Systematic Review and Mediation-Based Meta-Analysis

BACKGROUND

Although 24-hour movement behaviors are known to be interconnected, limited knowledge exists about whether change in one behavior during the COVID-19 pandemic (eg, increased screen time) was associated with change in another (eg, reduced physical activity or sleep). This review estimates mediational associations between changes in children's physical activity, screen time, and sleep during the COVID-19 pandemic.

METHODS

We included studies published between January 1, 2020 and June 27, 2022, in the PubMed/MEDLINE, Embase, PsycINFO, SPORTDiscus, and Web of Science databases. Summary data were extracted from included studies and analyzed with random-effects meta-regression.

RESULTS

This review included 26 studies representing 18,959 children across 18 mid-high-income countries (53% male; mean age, 11.5 [2.9] y). There was very good evidence of decreased total daily physical activity (factor change, 0.62; 90% CI, 0.47-0.81) and strong evidence of increased screen time (1.56; 90% CI, 1.38-1.77). There was very good evidence of decreased moderate to vigorous physical activity (0.75; 90% CI, 0.62-0.90) and weak evidence of increased sleep (1.02; 90% CI, 1.00-1.04). Mediational analysis revealed strong evidence that most of the reduction in total daily physical activity from before, to during, the pandemic was associated with increased screen time (0.53; 90% CI, 0.42-0.67). We observed no further mediational associations.

CONCLUSION

Increased reliance on and use of screen-based devices during the COVID-19 pandemic can be linked with reduced child and adolescent physical activity. This finding links COVID-related restrictions to potential displacement effects within child and adolescent 24-hour movement behavior.

Sleep Problems Before and During the COVID-19 Pandemic in Children with Autism Spectrum Disorder, Down Syndrome, and Typical Development

Sleep problems are common in children and adolescents, particularly those with Neurodevelopmental Disorders. With the changes in daily habits resulting from the COVID-19 pandemic, we have analyzed sleep characteristics, during social isolation, in Brazilian children and adolescents aged between 4 and 12 years with Autism Spectrum Disorder (N = 267), Down Syndrome (N = 74), and typical development (N = 312). The ASD group presented with worse indicators of sleep habits in the Children's Sleep Habits Questionnaire (CSHQ-BR) and fell asleep later during the pandemic. The entire group started fall asleep and waking up later during the pandemic - as well as waking up more often during the night. These results may contribute to parental guidance and sleep habit-related interventions during and after the COVID-19 pandemic.

Nursing Practice and Telehealth in School Health Services: A Scoping Review

BACKGROUND

The COVID-19 pandemic has propelled the adoption of telehealth in school settings, emphasising the pivotal role of nurses. This review explores the last decade's evidence on telehealth interventions in school nursing practice; Methods: Following Joanna Briggs Institute guidelines, we conducted a systematic search in PubMed, CINHAL, and Web of Science in March 2023. Out of 518 articles across 21 journals, 32 satisfied the review criteria. The selection process rigorously adhered to PRISMA-ScR guidelines for scoping reviews; Results: The results were categorised into three main areas: (a) the purpose of telehealth and intervention strategies, (b) the role of nursing in school-based telehealth practice, and (c) perceived benefits and limitations of school-based telehealth studies. Telehealth interventions encompass health promotion, mental health management, and early diagnosis. School nurses play a multifaceted role, including management, education, and remote monitoring. While telehealth offers advantages like improved health and cost savings, challenges include digital literacy, device access, and costs; Conclusion: This review underscores the crucial role of telehealth in schools for enhancing healthcare delivery in educational settings. However, more empirical evidence is required to specify nurses' contributions to school-based telehealth interventions. Promoting their leadership through stakeholder collaboration is essential. Further research should address challenges and opportunities in school nursing practice, enriching healthcare in educational settings.

Short Sleep Duration in School-Age Children: Differential Factors on Weekdays and Weekends

OBJECTIVES

To quantify school-age children's sleep and parent-associated factors on weekdays and weekends in Singapore, and investigate school-related and parent-related factors associated with short sleep.

METHODS

In an online survey, 251 parents with a child aged 7-12 y in Singapore reported their child's sleep duration and school start time. Parent-related factors including sleep hygiene (e.g., parent-set bedtime), sleep priority (the amount of sleep respondents allowed their children to trade for other activities), and both parents' sleep durations, were also reported.

RESULTS

The prevalence of short sleep among the children was 64.5% on weekdays and 19.5% on weekends. Children's sleep duration increased from 8.42 h on weekdays to 9.45 h on weekends (p < .001). Relative to weekdays, on weekends, parents showed similar increases in sleep durations (p < .001), imposed poorer sleep hygiene on their children (reduced likelihood of setting bedtimes and increased pre-bedtime electronic device use; p < .001), and allowed their children to trade more sleep for interacting with family and friends, social media, gaming, and TV / videos (p < .001). Shorter sleep duration in children was significantly associated with earlier school start time (B = 0.80, p = .02) and poorer sleep hygiene on weekdays (B = 0.16, p < .001), but lower sleep priority (B = 0.05, p = .002) and shorter parental sleep duration on weekends (maternal: B = 0.18, p < .001, paternal: B = 0.17, p = .002).

CONCLUSIONS

Delaying school start times may be effective in increasing school-age children's sleep duration on weekdays, while family-based interventions designed to enhance sleep hygiene, priority of sleep over other activities, and parents' sleep durations can benefit children's sleep duration on both weekdays and weekends.

School Belongingness as a Mediator in the Relationship Between Self-Reported PTSD and Cyber Victimization: Sex Differences

ABSTRACT

The incidence of posttraumatic stress disorder (PTSD) has increased during the COVID-19 pandemic. Traumatized adolescents might cope with maladaptive strategies such as increased Internet usage, which might be a risk for cyber victimization. We investigated the relationship between self-reported PTSD and cyber victimization and the mediator role of school belongingness in this relationship. The sample consisted of 292 adolescents ages 11-14 years old (M = 12.53, SD = 0.71; nfemale = 165, 56.1%; nmale = 129, 43.9%). Results show that males are more likely to be cyber victims and have lower levels of school belongingness than females. In addition, results supported the association between higher levels of PTSD and higher levels of cyber victimization. Traumatized adolescents with high levels of school belongingness are less likely to be cyber victims. These findings highlight the importance of school-related personal and relational characteristics in promoting adolescent mental health.

The impact of the COVID-19 pandemic on adolescent sleep behavior

Restorative sleep is a fundamental component of adolescent wellbeing, and the COVID-19 pandemic presented both challenges and opportunities for adolescents' sleep. In this review, we synthesize emergent themes from the growing scientific evidence for the impact of the pandemic on adolescent sleep behavior across different stages of the pandemic and in different locations around the world. We also highlight the ways in which COVID-19 shaped sleep patterns among college students-a subgroup of adolescents transitioning to emerging adulthood that were particularly impacted by the shift to remote learning. Finally, we discuss variations in the impact according to several potential moderating factors in adolescents' lives and point to areas that require additional longitudinal research.

The impact of the COVID-19 pandemic on sleep in children with Tourette syndrome in Ireland and the United Kingdom

STUDY OBJECTIVES

The aim of this mixed-methods study was to gain an insight through qualitative and quantitative means into the impact of the coronavirus disease 2019 (COVID-19) pandemic on children with and without Tourette syndrome (TS).

METHODS

Parents/guardians of children and adolescents with TS (n = 95; mean age = 11.2 years, standard deviation = 2.68 years) and typically developing controls (n = 86; mean age = 10.7 years, standard deviation = 2.8 years) in the United Kingdom and Ireland completed an online questionnaire examining sleep, with open-ended questions pertaining to their perceived impact of COVID-19 on the sleep of their children. Nine items from the Sleep Disturbance Scale for Children were used to supplement qualitative data.

RESULTS

A negative impact of the pandemic on the sleep of both groups was observed, including exacerbated tics, sleep deprivation, and anxiety, with particular disruption for children with TS. Parents of children with TS reported poorer sleep patterns than parents of typically developing children on the Sleep Disturbance Scale for Children. Analyses showed that group and age predicted 43.8% of variance in sleep duration: F (4, 176) = 34.2, P < .001.

CONCLUSIONS

Findings suggest that sleep patterns of children with TS may be more impacted by the pandemic than the average child. Given that there are generally more sleep issues reported in children with TS, further research is warranted in relation to the sleep health of children with TS in a postpandemic era. By identifying sleep issues potentially persisting after COVID-19, the true impact of the pandemic on the sleep of children and adolescents with Tourette syndrome may be ascertained.

Behavioral and Sleep Disorders in Children and Adolescents following COVID-19 Disease: A Case-Control Study

INTRODUCTION

Recent studies show that neuropsychiatric disorders are the most frequent sequelae of COVID-19 in children.

PURPOSE

Our work aimed to evaluate the impact of SARS-CoV-2 infection on behavior and sleep in children and adolescents.

MATERIALS AND METHODS

We enrolled 107 patients aged 1.5-18 years who contracted COVID-19 between one year and one month prior to data collection, referred to the University of Campania Luigi Vanvitelli in Italy. We asked their parents to complete two standardized questionnaires for the assessment of behavior (Child Behavior CheckList (CBCL)) and sleep (Sleep Disturbance Scale for Children (SLDS)). We analysed and compared the results with a control group (pre-COVID-19 pandemic).

RESULTS

In the COVID-19 group, the major results were found for sleep breathing disorders, sleep-wake transition disorders and disorders of initiating and maintaining sleep for the SDSC questionnaire, and internalizing scale, total scale and anxiety/depression for the CBCL questionnaire. The comparison of the CBCL results of the cases with the controls revealed statistically significant differences for the following items: internalizing scale, externalizing scale, somatic complaints, total score, thought problems [(p < 0.01)], anxious/depressed problems and withdrawn [(p < 0.001)].

CONCLUSIONS

COVID-19 has impacted children's and adolescents' mental health. Adolescents were the most affected patient group for internalizing problems, including anxiety and depression.

A National Survey of U.S. Adolescent Sleep Duration, Timing, and Social Jetlag During the COVID-19 Pandemic

OBJECTIVES

To assess changes in duration, timing, and social jetlag in adolescent sleep during the COVID-19 pandemic and evaluate the impact of mood, physical activity, and social interactions on sleep.

STUDY DESIGN

An online survey queried adolescents' sleep before (through retrospective report) and during the initial phase of COVID-19 in May 2020. Adolescents (N = 3,494), 13-19 years old, in the United States (U.S.) answered questions about their current and retrospective (prior to COVID-19) sleep, chronotype, mood, and physical and social activities. Linear regression models were fit for time in bed, reported bed and wake times, and social jetlag during COVID-19, accounting for pre-COVID-19 values.

RESULTS

Total reported time in bed (a proxy for sleep duration) increased on weekdays by an average of 1.3 ± 1.8 hours (p < .001) during COVID-19, compared to retrospective report of time in bed prior to COVID-19. During COVID-19, 81.3% of adolescents reported spending 8 hours or more in bed on weekdays compared to only 53.5% prior to COVID-19. On weekdays, bedtimes were delayed on average by 2.5 hours and wake times by 3.8 hours during COVID-19 compared to prior to COVID-19. On weekends, bedtimes were delayed on average by 1.6 hours and waketimes by 1.5 hours (all p's < 0.001). Social jetlag of >2 hours decreased to 6.3% during COVID-19 compared to 52.1% prior to COVID-19. Anxiety and depression symptoms and a decline in physical activity during COVID-19 were associated with delayed bed and wake times during COVID-19.

CONCLUSIONS

During COVID-19, adolescents reported spending more time in bed, with most adolescents reporting 8 hours of sleep opportunity and more consistent sleep schedules. As schools return to in-person learning, additional research should examine how sleep schedules may change due to school start times and what lessons can be learned from changes that occurred during COVID-19 that promote favorable adolescent sleep.

Determining the relationship between sleep disturbances in children and parental stress during COVID-19 pandemic

This study aimed to determine the relationship between child sleep disturbances and parental stress during the COVID-19 pandemic. This cross-sectional web-based study was conducted between February and April 2021 among 409 parents residing in Turkey who had children between the ages of 6 and 16 years. Data were collected online using the Sleep Disturbance Scale for Children (SDSC) and the Parental Stress Scale (PSS). In the study, there was a significant relationship found between the mean scores of the SDSC and PSS (r = 0.499, p < 0.001). In the multiple regression analysis, family type, socioeconomic status, occupation, the presence of sleep problems in the child before the pandemic, and the total score of the PSS significantly affected the total score of the SDSC. The presence of sleep problems in the child before the pandemic was significantly associated with the total score of the PSS (p < 0.05). Approximately 3.9% of the children had sleep disturbances (at scores over 70 points) during the COVID-19 pandemic. In conclusion, as the stress levels of parents increase, the rate of sleep disturbances in their children increases, and many demographic characteristics are associated with the occurrence of sleep disturbances in their children. It is important that parents do not reflect on their stress related to the pandemic and that their children maintain a normal sleep pattern whenever possible. School nurses should educate children and their parents about the importance of enough sleep and factors that contribute to inadequate sleep among children during the COVID-19 pandemic.

Sleep Deprivation and Insomnia in Adolescence: Implications for Mental Health

Sleep changes significantly throughout the human lifespan. Physiological modifications in sleep regulation, in common with many mammals (especially in the circadian rhythms), predispose adolescents to sleep loss until early adulthood. Adolescents are one-sixth of all human beings and are at high risk for mental diseases (particularly mood disorders) and self-injury. This has been attributed to the incredible number of changes occurring in a limited time window that encompasses rapid biological and psychosocial modifications, which predispose teens to at-risk behaviors. Adolescents’ sleep patterns have been investigated as a biunivocal cause for potential damaging conditions, in which insufficient sleep may be both a cause and a consequence of mental health problems. The recent COVID-19 pandemic in particular has made a detrimental contribution to many adolescents’ mental health and sleep quality. In this review, we aim to summarize the knowledge in the field and to explore implications for adolescents’ (and future adults’) mental and physical health, as well as to outline potential strategies of prevention.

Changes in lifestyle behaviors during the COVID-19 pandemic in children and adolescents with congenital heart disease

OBJECTIVE

To describe the changes in lifestyle behaviors during the COVID-19 pandemic in children and adolescents with congenital heart disease and to investigate the association of congenital heart disease complexity with lifestyle behavior changes.

METHODS

Cross-sectional study with 127 children and adolescents with congenital heart disease, who underwent cardiac procedure (mean postoperative time: 10.11±3.13 years), conducted between December 2020 and January 2021. Lifestyle behaviors, such as dietary intake, physical activity, sedentary behavior, and sleep, were assessed through telephone interview based on validated questionnaires. Dietary patterns were identified using principal component analysis. Frequency of general and specific combinations of healthy and unhealthy lifestyle behavior changes was evaluated. Multinomial logistic regressions were used to test the association between congenital heart disease complexity and changes in lifestyle behavior.

RESULTS

The main lifestyle behaviors acquired during pandemic were: 83.5% decreased physical activity; 37.0% increased sedentary behavior; 26.0% slept more than usual; and 23.6% adopted a less-healthy dietary pattern. Almost half of the participants (41.8%) had at least one unhealthy change in lifestyle behavior. Complex congenital heart diseases were associated with increased sedentary behavior (OR 3.49, 95%CI 1.23-9.90).

CONCLUSIONS

Children and adolescents with congenital heart disease had unhealthy lifestyle behavior during the pandemic, mainly in the form of reduced physical activity and increased sedentary behavior.

The impacts of physical activity on psychological and behavioral problems, and changes in physical activity, sleep and quality of life during the COVID-19 pandemic in preschoolers, children, and adolescents: A systematic review and meta-analysis

Background

The COVID-19 pandemic has greatly affected the level of physical activity (PA). However, little is known about its effect on health outcomes.

Methods

Articles without language restrictions published from the database inception through March 16, 2022, were retrieved using the CINAHL Complete, Cochrane Library, EMBASE, Medline, PubMed, and PsycINFO databases. High-quality articles assessing the effect of PA on psychological and behavioral problems. Additionally, PA, QoL, and/or sleep problems before and during the pandemic were included. Articles without data regarding PA or involving non-general populations were excluded. The PRISMA and MOOSE guidelines were followed. Data quality of the selected articles was assessed using the Newcastle-Ottawa Scale and GRADE approach. Data were pooled using a random-effects model and sensitivity analysis if heterogenicity was high (I 2 ≥ 50%). The relationship between PA and psychological and behavioral problems; and changes in PA, QoL, and sleeping patterns before and during the pandemic in preschoolers, children, and adolescents were investigated. A meta-analysis was conducted; odds ratios (ORs), mean differences (MD), and standardized MDs (SMDs) were calculated.

Results

Thirty-four articles involving 66,857 participants were included. The results showed an overall significant protective effect between PA and psychological and/or behavioral problems (OR = 0.677; 95% CI = 0.630, 0.728; p-value <0.001; I 2   = 59.79%). This relationship was also significant in the subgroup analysis of children (OR = 0.690; 95% CI = 0.632, 0.752; p-value <0.001; I 2   = 58.93%) and adolescents (OR = 0.650; 95% CI = 0.570, 0.741; p-value <0.001; I 2   = 60.85%); however, no data on the relationship in preschoolers were collected. In addition, the overall time spent on PA significantly decreased by 23.2 min per day during the COVID-19 pandemic (95% CI = -13.5, -32.9; p-value <0.001; I 2   = 99.82%). Moreover, the results showed an overall significant decrease in QoL (SMD = -0.894, 95% CI = -1.180, -0.609, p-value <0.001, I 2   = 96.64%). However, there was no significant difference in sleep duration during the COVID-19 pandemic (MD = 0.01 h per day, 95% CI = -0.027, 0.225; p-value = 0.125; I 2   = 98.48%).

Conclusion

During the pandemic, less PA was contributed to poor QoL and sleep quality. However, increases in PA are associated with reduced occurrences of psychological and behavioral problems. Implementing recovery plans to address the health effect of the pandemic is essential.

COVID-19 Policies, Pandemic Disruptions, and Changes in Child Mental Health and Sleep in the United States

IMPORTANCE

The adverse effects of COVID-19 containment policies disrupting child mental health and sleep have been debated. However, few current estimates correct biases of these potential effects.

OBJECTIVES

To determine whether financial and school disruptions related to COVID-19 containment policies and unemployment rates were separately associated with perceived stress, sadness, positive affect, COVID-19-related worry, and sleep.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study was based on the Adolescent Brain Cognitive Development Study COVID-19 Rapid Response Release and used data collected 5 times between May and December 2020. Indexes of state-level COVID-19 policies (restrictive, supportive) and county-level unemployment rates were used to plausibly address confounding biases through 2-stage limited information maximum likelihood instrumental variables analyses. Data from 6030 US children aged 10 to 13 years were included. Data analysis was conducted from May 2021 to January 2023.

EXPOSURES

Policy-induced financial disruptions (lost wages or work due to COVID-19 economic impact); policy-induced school disruptions (switches to online or partial in-person schooling).

MAIN OUTCOMES AND MEASURES

Perceived stress scale, National Institutes of Health (NIH)-Toolbox sadness, NIH-Toolbox positive affect, COVID-19-related worry, and sleep (latency, inertia, duration).

RESULTS

In this study, 6030 children were included in the mental health sample (weighted median [IQR] age, 13 [12-13] years; 2947 [48.9%] females, 273 [4.5%] Asian children, 461 [7.6%] Black children, 1167 [19.4%] Hispanic children, 3783 [62.7%] White children, 347 [5.7%] children of other or multiracial ethnicity). After imputing missing data, experiencing financial disruption was associated with a 205.2% [95% CI, 52.9%-509.0%] increase in stress, a 112.1% [95% CI, 22.2%-268.1%] increase in sadness, 32.9% [95% CI, 3.5%-53.4%] decrease in positive affect, and a 73.9 [95% CI, 13.2-134.7] percentage-point increase in moderate-to-extreme COVID-19-related worry. There was no association between school disruption and mental health. Neither school disruption nor financial disruption were associated with sleep.

CONCLUSIONS AND RELEVANCE

To our knowledge, this study presents the first bias-corrected estimates linking COVID-19 policy-related financial disruptions with child mental health outcomes. School disruptions did not affect indices of children's mental health. These findings suggest public policy should consider the economic impact on families due to pandemic containment measures, in part to protect child mental health until vaccines and antiviral drugs become available.

Associations between screen use, outdoor time/daylight exposure and sleep changes during the first COVID-19 lockdown in French children from the ELFE and EPIPAGE2 birth cohorts

AIMS

To investigate associations between outdoor and screen time and changes in sleep patterns in children from two nationwide birth-cohorts in the SAPRIS project.

METHODS

During the first French COVID-19 pandemic lockdown, volunteer parents of children enrolled in the ELFE and EPIPAGE2 birth-cohorts completed online questions about their child's outdoor time, screen time, and changes in sleep duration and quality compared with the pre-lockdown situation. In 5700 children (aged 8-9 years, 52% boys) with available data, we assessed associations between outdoor time, screen time, and sleep changes using multinomial logistic regression models adjusted for confounders.

RESULTS

Children spent on average 3 h08 outdoors and 4 h34 using screens/day (3 h27 for leisure, 1 h07 for class-work). Sleep duration increased in 36% of children and decreased in 13.4%; sleep difficulties appeared/increased in 22.5% and decreased/disappeared/remained stable in 18.3%. After adjustment, increased screen time, especially for leisure, was associated with increased and decreased sleep duration (OR(95%CI) = 1.03(1.00-1.06) and OR = 1.06(1.02-1.10), respectively). No association was observed between outdoor time and sleep changes after adjustment.

CONCLUSIONS

Our study adds evidence for the association between high leisure-time screen time and shorter sleep time. It supports current screen guidelines for children, especially during leisure time and for those whose sleep duration is short.

Parental survey of the sleep patterns and screen time in US school children during the first 6 months of the COVID-19 pandemic

BACKGROUND

This study compared sleep duration, screen exposure and sleep quality in school-aged children before COVID-19 to that during school closures and again when schools re-opened in fall 2020.

METHODS

Cross-sectional anonymous, online survey of parents of children 5-13 years old. Questions elicited information about sleep timing and quality, screen time, and schooling at three distinct periods: before the pandemic, when schools first closed and then re-opened in the fall.

RESULTS

Respondents described 101 children who were an average of 8.5 years old and 51% male. In lockdown, children slept 25 min more (95%CI 00:13-00:38) due to later wake times (75 min, 95% CI 0:57-1:34) with later bedtimes (29 min, 95%CI 0:00-0:58). When schools re-opened, sleep duration returned to pre-pandemic levels, but sleep onset and offset times remained later. Despite more sleep, sleep quality and habits (e.g. bedtime refusal) worsened during lockdown and did not normalize in fall 2020. During lockdown, screen time increased in 65% of all children, and 96% of those in private schools. When schools reopened, 78% of children in hybrid/virtual learning had more than 4 h of screen exposure daily. Less screen time was associated with twofold higher odds of better sleep (OR 2.66, 95%CI 1.15-6.14).

CONCLUSIONS

Although school-aged children had more total sleep when schools were closed, sleep quality and habits worsened. Upon return to school, sleep times and quality did not normalize and were linked to screen time.

Child Anxiety and Depression Symptom Trajectories and Predictors over 15 Months of the Coronavirus Pandemic

Repeated measures are required to monitor and map trajectories of mental health symptoms that are sensitive to the changing distal and proximal stressors throughout the coronavirus (COVID-19) pandemic. Understanding symptoms in young children is particularly important given the short- and long-term implications of early-onset internalizing symptoms. This study utilized an intensive longitudinal approach to assess the course and environmental correlates of anxiety and depression symptoms in 133 children, ages 4-11 (Mage = 7.35, SD = 1.03), in the United States during the COVID-19 pandemic. Caregivers completed 48 repeated assessments from April 7, 2020, to June 15, 2021, on child and caregiver mental health symptoms, family functioning, and COVID-19-related environmental changes. Results from a series of multilevel growth models demonstrate that child depression symptoms were highest following initial stay-at-home orders (April 2020) and linearly decreased over time, while child anxiety symptoms were variable over the 15-month period. Caregiver depression symptoms and family conflict significantly predicted levels of child depression symptoms. In contrast, caregiver depression symptoms, caregiver anxiety symptoms, and time spent home quarantining significantly predicted levels of child anxiety symptoms. Results suggest that depression and anxiety symptoms in young children may have unique trajectories over the course of the coronavirus pandemic and highlight symptom-specific risk factors for each symptom.

Impact of the COVID-19 pandemic on children's sleep habits: an ECHO study

BACKGROUND

Sleep in childhood is affected by behavioral, environmental, and parental factors. We propose that these factors were altered during the COVID-19 pandemic. This study investigates sleep habit changes during the pandemic in 528 children 4-12 years old in the US, leveraging data from the Environmental Influences on Child Health Outcomes (ECHO) Program.

METHODS

Data collection occurred in July 2019-March 2020 (pre-pandemic) and two pandemic periods: December 2020-April 2021 and May-August 2021. Qualitative interviews were performed in 38 participants.

RESULTS

We found no changes in sleep duration, but a shift to later sleep midpoint during the pandemic periods. There was an increase in latency at the first pandemic collection period but no increase in the frequency of bedtime resistance, and a reduced frequency of naps during the pandemic. Qualitative interviews revealed that parents prioritized routines to maintain sleep duration but were more flexible regarding timing. Children from racial/ethnic minoritized communities slept less at night, had later sleep midpoint, and napped more frequently across all collection periods, warranting in-depth investigation to examine and address root causes.

CONCLUSIONS

The COVID-19 pandemic significantly impacted children sleep, but parental knowledge of the importance of sleep might have played a significant protective role.

IMPACT

During the COVID-19 pandemic, US children changed their sleep habits, going to bed and waking up later, but their sleep duration did not change. Sleep latency was longer. Parental knowledge of sleep importance might have played a protective role. Regardless of data collection periods, children from racial/ethnic minoritized communities slept less and went to bed later. This is one of the first study on this topic in the US, including prospective pre-pandemic qualitative and quantitative data on sleep habits. Our findings highlight the pandemic long-term impact on childhood sleep. Results warrants further investigations on implications for overall childhood health.

Understanding the Need for Sleep to Improve Cognition

The restorative function of sleep is shaped by its duration, timing, continuity, subjective quality, and efficiency. Current sleep recommendations specify only nocturnal duration and have been largely derived from sleep self-reports that can be imprecise and miss relevant details. Sleep duration, preferred timing, and ability to withstand sleep deprivation are heritable traits whose expression may change with age and affect the optimal sleep prescription for an individual. Prevailing societal norms and circumstances related to work and relationships interact to influence sleep opportunity and quality. The value of allocating time for sleep is revealed by the impact of its restriction on behavior, functional brain imaging, sleep macrostructure, and late-life cognition. Augmentation of sleep slow oscillations and spindles have been proposed for enhancing sleep quality, but they inconsistently achieve their goal. Crafting bespoke sleep recommendations could benefit from large-scale, longitudinal collection of objective sleep data integrated with behavioral and self-reported data.

Longitudinal trends in parent-reported child sleep, physical activity, and screen use during the COVID-19 pandemic in New York City

Objective

To examine trends in child sleep, physical activity, and screen use during the COVID-19 pandemic in New York City with a prospective, longitudinal online survey of parents recruited from a large medical center.

Methods

Data was collected Spring 2020 ("Complete Shutdown") and Fall 2020 ("Partial Shutdown"). Outcomes were parental perceptions about changes in child sleep, physical activity, and screen time compared to before COVID-19; and contemporaneous measures of these child behaviors. We report contemporaneous responses and paired analyses to describe longitudinal changes.

Results

Two hundred seventy-seven participants were surveyed during Complete Shutdown and 227 (81.9%) filled out a follow-up survey during Partial Shutdown. The largest percentage of parents at both time points perceived no change in child sleep, decreases in child exercise, and increases in child screen time. In paired analyses, perceptions shifted toward less sleep, more physical activity and less screen time from Complete Shutdown to Partial Shutdown.

Conclusion

COVID-19 had negative impacts on child health behaviors that did not resolve over a 6-month period despite partial reopenings.

Impact of COVID-19 pandemic on adherence to noninvasive ventilation in children

STUDY OBJECTIVES

The aim of this study was to measure changes in adherence to noninvasive ventilation (NIV) in children during the first year of the COVID-19 pandemic.

METHODS

Retrospective chart review of children (0-18 years) using home NIV through the Stollery's Pediatric NIV program in Edmonton, Canada during March 2019 to March 2021. Demographics, clinical characteristics, and adherence information from machine downloads were collected prior to and during the first year of the COVID-19 pandemic. Paired t tests and Chi-square compared adherence prepandemic and during pandemic and repeated analysis of variance tests compared adherence pre- and 0-6 and 6-12 months during pandemic.

RESULTS

Eighty-two children met inclusion criteria (62% male; age 8.6 ± 4.6 years). Overall, there were no changes in NIV adherence during pandemic (average NIV minutes pre- and during pandemic of 390 ± 219 and 405 ± 300 minutes, respectively). When separated into increased vs decreased adherence groups, adherence differences pre- compared to during pandemic became significant, with no differences across demographic/clinical variables or prepandemic adherence. There were no changes in NIV adherence during the initial 6 months of pandemic compared to prepandemic, but NIV use significantly increased by 9-57 minutes during the following 6-12 months. Bilevel positive airway users had longer NIV use than continuous positive airway pressure users at all time points, with an overall increasing trend over time.

CONCLUSIONS

Despite the significant life disruption created by COVID-19 and changes to virtual care, children using home NIV maintained adequate adherence. Qualitative research is needed to understand the nuances of using NIV during the pandemic and potential advantages of virtual care for support of these children and families.

Trends in Pediatric Head and Facial Trauma During the COVID-19 Pandemic

INTRODUCTION

The effect of physical-distancing policies and school closures on pediatric health has been a topic of major concern in the United States during the coronavirus disease 2019 (COVID-19) pandemic. The objective of this study was to assess the immediate impact of these public policies on patterns of head and facial trauma in the pediatric population.

MATERIALS AND METHOD

The Pediatric Health Information System (PHIS) was queried to identify patient encounters at 46 children's hospitals across the United States in 2016-2020. Encounters were included if resultant in ICD-10 diagnosis for head or facial trauma in a child under 18 between April 1 and June 30 in 2020 (first COVID-19 school closures) and during the same period in the previous 4 years (for comparison).

RESULTS

A total of 170,832 patient encounters for pediatric head and facial trauma were recorded during the study period, including 28,030 (16.4%) in 2020 and 142,802 (83.6%) in 2016-2019. Patient encounters declined significantly in 2020 among children of all age groups relative to previous years. Relative reductions were greatest in children aged 11 to 17 (middle/high school) and 6 to 10 (elementary school), at -34.6% (95% confidence interval: -23.6%, -44%; P <0.001) and -27.7% (95% confidence interval: -18.4%, -36%; P <0.001). Variation in relative reductions by race/ethnicity, sex, and rural/urban status were not statistically significant.

CONCLUSIONS

Physical-distancing policies and school closures at the start of the COVID-19 pandemic correlated with significant reductions in pediatric head and facial trauma patient encounters. As in-person activities resume, reductions in head and facial trauma during the pandemic may indicate a range of possible preventable injuries in the future.

Working-from-home persistently influences sleep and physical activity 2 years after the Covid-19 pandemic onset: a longitudinal sleep tracker and electronic diary-based study

Objective

Working from home (WFH) has become common place since the Covid-19 pandemic. Early studies observed population-level shifts in sleep patterns (later and longer sleep) and physical activity (reduced PA), during home confinement. Other studies found these changes to depend on the proportion of days that individuals WFH (vs. work from office; WFO). Here, we examined the effects of WFH on sleep and activity patterns in the transition to normality during the later stages of the Covid-19 pandemic (Aug 2021-Jan 2022).

Methods

Two-hundred and twenty-five working adults enrolled in a public health study were followed for 22  weeks. Sleep and activity data were collected with a consumer fitness tracker (Fitbit Versa 2). Over three 2-week periods (Phase 1/week 1-2: August 16-29, 2021; Phase 2/week 11-12: October 25-November 7, 2021; Phase 3/week 21-22: January 3-16, 2022), participants provided daily Fitbit sleep and activity records. Additionally, they completed daily phone-based ecological momentary assessment (EMA), providing ratings of sleep quality, wellbeing (mood, stress, motivation), and information on daily work arrangements (WFH, WFO, no work). Work arrangement data were used to examine the effects of WFH vs. WFO on sleep, activity, and wellbeing.

Results

The proportion of WFH vs. WFO days fluctuated over the three measurement periods, mirroring evolving Covid restrictions. Across all three measurement periods WFH days were robustly associated with later bedtimes (+14.7 min), later wake times (+42.3 min), and longer Total Sleep Time (+20.2 min), compared to WFO days. Sleep efficiency was not affected. WFH was further associated with lower daily step count than WFO (-2,471 steps/day). WFH was associated with higher wellbeing ratings compared to WFO for those participants who had no children. However, for participants with children, these differences were not present.

Conclusion

Pandemic-initiated changes in sleep and physical activity were sustained during the later stage of the pandemic. These changes could have longer term effects, and conscious effort is encouraged to harness the benefits (i.e., longer sleep), and mitigate the pitfalls (i.e., less physical activity). These findings are relevant for public health as hybrid WHF is likely to persist in a post-pandemic world.

Unprecedented times and uncertain connections: A systematic review examining sleep problems and screentime during the COVID-19 pandemic

Objective

Sleep has been impacted by the COVID-19 pandemic around the world. Furthermore, screen time has been reported to influence sleep and has increased during pandemic quarantines. This systematic review searched databases to determine if screen time affected sleep during the COVID-19 pandemic.

Methods

PubMed, Nursing and Allied Health Proquest, and Science Direct Health and Lifescience college edition were searched for articles that fit the inclusion criteria. There were 2750 articles initially screened. Then, 119 articles were further assessed to determine eligibility, creating a final sample of 18 articles that explored whether screen time affected sleep.

Results

After reviewing the included articles (n = 18), the main theme revealed that screen time negatively affected sleep during the COVID-19 pandemic, specifically aspects such as sleep duration, sleep quality, sleep onset latency, and wake time. However, several articles countered this implication. Therefore, it is important to consider other factors that may influence the relationship between screen time and sleep.

Conclusions

Although the number of articles included is limited, the overall synthesis suggests that COVID-19-related lifestyle changes, such as increased screen time, may negatively affect sleep health. However, other unidentified factors may have contributed to these findings and warrant further research. Nonetheless, community leaders must consider the long-term consequences of the pandemic and implement initiatives to address sleep challenges due to the intricate connection between sleep and well-being.

Self-reported changes in sleep patterns and behavior in children and adolescents during COVID-19

The COVID-19 pandemic and lockdowns worldwide forced children and adolescents to change and adapt their lives to an unprecedented situation. Using an online survey, we investigated whether they showed changes in sleep quality and other related factors due to this event. Between February 21st, 2021 and April 19th, 2021, a total of 2,290 Austrian children and adolescents (6-18 years) reported their sleep habits and quality of sleep as well as physical activity, daylight exposure and usage of media devices during and, retrospectively, before the pandemic. Results showed an overall delay of sleep and wake times. Almost twice as many respondents reported having sleeping problems during the pandemic as compared to before, with insomnia, nightmares and daytime sleepiness being the most prevalent problems. Furthermore, sleeping problems and poor quality of sleep correlated positively with COVID-19 related anxiety. Lastly, results showed a change from regular to irregular bedtimes during COVID-19, higher napping rates, a strong to very strong decrease in physical activity and daylight exposure, as well as a high to very high increase in media consumption. We conclude that the increase in sleeping problems in children and adolescent during COVID-19 is concerning. Thus, health promoting measures and programs should be implemented and enforced.

The Associations between 24-Hour Movement Behaviours and Quality of Life in Preschoolers: A Compositional Analysis of Cross-Sectional Data from 2018-2021

Studies show that the quality of life (QoL) of preschoolers is closely related to physical activity (PA), sedentary behaviour (SB), and sleep (SL). Yet many researchers looked at these 24-h movement behaviours as behaviours that are independent of one another when examining the association of QoL with these behaviours. The main purpose of the present study was to describe the temporal trends in PA, SB, and SL in preschoolers and the concomitant association with QoL of children. Annual cross-sectional data on QoL and 24-h movement behaviours of 8045 Singaporean preschoolers were collected from 2018 to 2021. Compositional analysis, linear regression, and isotemporal replacement approaches were used to examine changes in PA, SB, and SL from 2018-2021 and how these changes were associated with QoL. Temporal trends in movement behaviours showed that PA and SL decreased after 2020. During 2018-2021, the association of PA and QoL in preschoolers was characterised by a 'U' curve (βPA-2018 = 3.06, p < 0.001; βPA-2019 = 1.43, p < 0.05; βPA-2020 = -0.43, p > 0.05; βPA-2021 = 2.82, p < 0.001), while SL and QoL were characterised by an inverted 'U' curve (βSL-2018 = -2.39, p < 0.001; βSL-2019 = -0.27, p > 0.05; βSL-2020 = 2.00, p < 0.01; βSL-2021 = -0.21, p > 0.05). SB was significantly and negatively associated with QoL after 2020, with 2020 identified as the inflection point for the change in SB (βSB-2018 = 0.67, p > 0.05; βSB-2019 = -1.16, p > 0.05; βSB-2020 = -1.56, p < 0.01; βSB-2021 = -2.61, p < 0.01). Using a time re-allocation technique to treat the 2021 data, reallocating time from SB to PA or to SL predicted improvements in QoL of preschoolers (Pall < 0.05). The study provided useful information on the temporal trends in PA, SB, SL, and QoL of preschoolers over four years. Additionally, these data provided insights into how changes in QoL are predicted by changes in duration in the 24-h movement behaviours.

Protective measures feasibility for infants of low-income SARS-CoV-2 positive breastfeeding mothers: A prospective multicentre cohort study

AIM

The aim was to evaluate the feasibility of protective measures for infants of low-income SARS-CoV-2 positive breastfeeding mothers.

BACKGROUND

Breastfeeding mothers with SARS-CoV-2 positive should avoid exposing the infant through protective measures (PM), but it could be challenging in a low-income population.

METHODS

A prospective, multicentre study was conducted between July and October 2020 (BRACOVID). The participants were recruited at birth and interviewed through a structured questionnaire at 7 and 14 days in the home environment. The feasibility of PM during breastfeeding at home was defined by guidelines recommendations (mask using, handwashing, and distancing from newborn when not breastfeeding). Three groups according to the feasibility of guidelines: complete guidelines feasibility (CG): all PM; partial guidelines feasibility (PG): at least one PM feasible; no guidelines (NG): infeasibility to all of PM. Flu-like neonatal symptoms and breastfeeding practices were analyzed. We evaluated the association between PM feasibility and socioeconomic factors.

RESULTS

One hundred seventeen infected mothers from 17 Brazilian hospitals were enrolled. Forty-seven (40%) mothers followed all recommendations, 14 (11.9%) could not practice at least one recommendation, and 50 (42.7%) did not execute any of them. The breastfeeding rate was 98%. Factors associated with infeasibility were monthly family income <92.7 dollars/person, high housing density (>1 inhabitant/room), teenage mothers, responsive feeding, and poor schooling. Regarding infants' flu-like symptoms, 5% presented symptoms at 14 days (NG group).

CONCLUSION

The guidelines were not applied to infants of SARs-CoV-positive mothers in 54.6% of the dyads since the recommendations were unviable in their environments. During pandemics, we should look for feasible and effective guidelines to protect neonates from low-income populations.

IMPLICATIONS FOR NURSING MANAGEMENT

Poor socioeconomic conditions lead to the unfeasibility of protective measures for infants of low-income SARS-CoV-2 positive breastfeeding mothers during the isolation period in the pandemics. The orientations and the support provided to dyad should consider the socioeconomic factors to guide feasible measures in the home environment and promote adequate protections; only an individual approach will allow a safe environment for low-income infants. The Research Ethics Committee approved the project of the Medicine School in Ribeirão Preto, University of São Paulo, Brazil (CAAE: 31357320.9.1001.5440-4.066.741/2020) and Brazilian hospitals and maternal services.

Effects of the COVID-19 pandemic on sleep quality in children and adolescents: A systematic review and meta-analysis

We synthesise the literature on the potential influence of the COVID-19 pandemic on sleep quality in children and adolescents. The search identified studies that examined the relationship between sleep quality and disorders during the COVID-19 pandemic. It began in May 2021 and has had two updates with the last in January 2022. The databases used were LILACS, PubMed, and EMBASE. Random effects models were performed to explore heterogeneity between studies. Data were presented as continuous variables (mean value and standard deviation) to perform a meta-analysis. Twenty-nine studies from 16 countries were identified: Nine had children and eight had adolescents. The overall quality of the studies ranged from high (27.6%) to medium (65.5%) and low (6.9%). Eight studies were eligible for meta-analysis. There was an increase in sleep duration during the pandemic when compared with the previous period 0.33 (95%CI -0.07; 0.60) (p < 0.001) and late bedtime 0.78 (95%CI -0.33; 1.22) (p < 0.001). A trend toward reduced sleep efficiency was also detected 0.54 (95%CI -0.75; -0.33) p = 0.20. Parents' reports of increased use of screen media/electronic devices were associated with worse sleep quality. The results suggest an influence of the pandemic on sleep characteristics such as increased sleep duration, late bedtimes, and poor sleep quality. These alterations were related to changes in family routines during this period.

Methodologies and Wearable Devices to Monitor Biophysical Parameters Related to Sleep Dysfunctions: An Overview

Sleep is crucial for human health from metabolic, mental, emotional, and social points of view; obtaining good sleep in terms of quality and duration is fundamental for maintaining a good life quality. Over the years, several systems have been proposed in the scientific literature and on the market to derive metrics used to quantify sleep quality as well as detect sleep disturbances and disorders. In this field, wearable systems have an important role in the discreet, accurate, and long-term detection of biophysical markers useful to determine sleep quality. This paper presents the current state-of-the-art wearable systems and software tools for sleep staging and detecting sleep disorders and dysfunctions. At first, the paper discusses sleep's functions and the importance of monitoring sleep to detect eventual sleep disturbance and disorders. Afterward, an overview of prototype and commercial headband-like wearable devices to monitor sleep is presented, both reported in the scientific literature and on the market, allowing unobtrusive and accurate detection of sleep quality markers. Furthermore, a survey of scientific works related the effect of the COVID-19 pandemic on sleep functions, attributable to both infection and lifestyle changes. In addition, a survey of algorithms for sleep staging and detecting sleep disorders is introduced based on an analysis of single or multiple biosignals (EEG-electroencephalography, ECG-electrocardiography, EMG-electromyography, EOG-electrooculography, etc.). Lastly, comparative analyses and insights are provided to determine the future trends related to sleep monitoring systems.

Risks of Digital Screen Time and Recommendations for Mitigating Adverse Outcomes in Children and Adolescents

BACKGROUND

The COVID-19 pandemic caused an unprecedented move to emergency remote learning around the world, leading to increased digital screen time for children and adolescents. This review highlights the potential risk of increased screen time to the eye and general health and makes recommendations to mitigate the risks posed.

METHODS

A narrative review of evidence of increased digital time during the COVID-19 pandemic, the risks linked to increased screen time and offer possible steps to mitigate these in students.

RESULTS

Digital screen time was found to have increased for children and adolescents in all the studies examined during the pandemic and data suggests that this has an impact on eye and general health. We discuss the associated risk factors and adverse outcomes associated with increased digital screen time.

CONCLUSIONS

This review offers evidence of increased digital time, highlights some of the well-known and not so well-known risks linked to increased screen time, and offers possible steps to mitigate these in children and adolescents during the pandemic, as well as offering schools and parents strategies to support the eye health of children and adolescents post-pandemic. We discuss a number of interventions to reduce the risk of eye strain, myopia, obesity, and related diseases that have been shown to be linked to increased digital screen time.

Health Behavior Changes during the COVID-19 Pandemic: A Longitudinal Analysis among Children

This longitudinal study compared children’s health behaviors before the COVID-19 pandemic versus during the pandemic. This analysis examined the association between individual-level characteristics and health behavior change. Four prospective cohort studies in the Environmental influences on Child Health Outcomes (ECHO) Program contributed data. Children aged 4−12 years and their caregivers were recruited in California, Colorado, North Dakota, and New Hampshire. Dietary intake, physical activity, screen time, and sleep duration were assessed with questionnaires pre-pandemic and during the pandemic. The final sample included 347 children: 47% female and 62% non-Hispanic White. Compared with pre-pandemic, weekday screen time duration was higher during the pandemic (3.0 vs. 4.5 h, p < 0.001). Unadjusted increases in screen time duration differed by race and ethnicity: 1.3 h/day for non-Hispanic White children, 2.3 h/day for Hispanic children, and 5.3 h/day for non-Hispanic Black children. Overall, no changes occurred in sugar-sweetened beverage (SSB) intake (p = 0.26), discretionary food intake (p = 0.93), and physical activity (p = 0.15). Sleep duration increased by 30 min among children who did not meet sleep recommendations pre-pandemic. Child sex and maternal education level were not associated with health behavior change. The pandemic may have exacerbated disparities in some health behaviors. Families may need support to re-establish healthy routines.

COVID-19 Pandemic Impact on Family Life and Exacerbated Emotional and Behavioral Health among Preschool Children: A Longitudinal Study

Background/Objective

This study aimed to examine associations of the impact of COVID-19 pandemic on family life with emotional and behavioral health among preschool children.

Methods

A longitudinal study including 1595 preschool children aged 3–6 years and their families was conducted in Anhui Province. The linear regression was applied to examine associations between the impact of COVID-19 pandemic on family life and emotional and behavioral health.

Results

Results of the multivariable linear regression indicated that the severe impact of COVID-19 pandemic on family life was significantly associated with more sleep problems, poor dietary behavior habits, more anxiety symptoms, and more problematic behaviors; and these effects exhibited gender and age differences.

Conclusions

The severe impact of COVID-19 pandemic on family life significantly increased the risk for exacerbated emotional and behavioral health among preschool children. It is considered vital to identify risk factors for vulnerable families and then to implement precise interventions when necessary for emotional and behavioral health of children in these families.

School Closures in the United States and Severe Respiratory Illnesses in Children: A Normalized Nationwide Sample

OBJECTIVES

To determine the association between nationwide school closures and prevalence of common admission diagnoses in the pediatric critical care unit.

DESIGN

Retrospective cohort study.

SETTING

National database evaluation using the Virtual Pediatric Systems LLC database.

PATIENTS

All patients admitted to the PICU in 81 contributing hospitals in the United States.

MEASUREMENTS AND MAIN RESULTS

Diagnosis categories were determined for all 110,418 patients admitted during the 20-week study period in each year (2018, 2019, and 2020). Admission data were normalized relative to statewide school closure dates for each patient using geographic data. The "before school closure" epoch was defined as 8 weeks prior to school closure, and the "after school closure" epoch was defined as 12 weeks following school closure. For each diagnosis, admission ratios for each study day were calculated by dividing 2020 admissions by 2018-2019 admissions. The 10 most common diagnosis categories were examined. Significant changes in admission ratios were identified for bronchiolitis, pneumonia, and asthma. These changes occurred at 2, 8, and 35 days following school closure, respectively. PICU admissions decreased by 82% for bronchiolitis, 76% for pneumonia, and 76% for asthma. Nonrespiratory diseases such as diabetic ketoacidosis, status epilepticus, traumatic injury, and poisoning/ingestion did not show significant changes following school closure.

CONCLUSIONS

School closures are associated with a dramatic reduction in the prevalence of severe respiratory disease requiring PICU admission. School closure may be an effective tool to mitigate future pandemics but should be balanced with potential academic, economic, mental health, and social consequences.

Changes and correlates of screen time in adults and children during the COVID-19 pandemic: A systematic review and meta-analysis

Background

Screen time has increased as a result of the COVID-19 pandemic, and several correlates have been associated with these increases. These changes, however, have not been aggregated. It was the aim of this review to (a) aggregate changes in screen time in adults and children, and (b) report on variables in relation to screen time during the COVID-19 pandemic.

Methods

A systematic review of major databases was undertaken for studies published from inception to 06/12/2021, using a pre-published protocol (PROSPERO ID: CRD42021261422). Studies reporting (a) screen time pre-versus-during the pandemic, (b) screen time percentage change, or (c) correlates of screen time during the pandemic were included. A random effects meta-analysis was undertaken with subgroup analysis by age group and type of screen time.

Findings

After review, 89 studies (n = 204,734; median age=20·6; median female=53·3%) were included. The majority of studies were cross-sectional. With regards to total screen time, primary aged children (6-10 years) reported largest increases (1·4 hrs/day; 95%CI 1·1-1·7), followed by adults (>18 years; 1·0 hrs/day; 95%CI 0·7-1·2), adolescents (11-17 years; 0·9 hrs/day; 95%CI 0·3-1·5), and young children (0-5 years; 0·6 hrs/day 95%CI 0·3-0·9 hrs/day). For leisure screen time (non-work/non-academic), primary aged children reported largest increases (1·0 hrs/day 95%CI 0·8-1·3), followed by adults (0·7hr/day 95%CI 0·3-1·2), young children (0·6 hrs/day; 95%CI 0·4-0·8), with adolescents reporting the lowest increase (0·5 hrs/day 95%CI 0·3-0·7). Several correlates were associated with reported increases in screen time, including adverse dietary behaviours, sleep, mental health, parental health, and eye health.

Interpretation

Pooled evidence suggest that primary aged children reported the highest increase in both total and leisure screen time during COVID-19. It is recommended that screen time should be reduced in favour of non-sedentary activities. This study has the potential to inform public health policy and future guidance regarding screen time, and to inform future research in this area.

Funding

No funding was received for this study.

The Impact of the COVID-19 Lockdown “Home Quarantine” on the Physical Activity and Lifestyle of Children in Qatar

Background

Several studies have investigated how the coronavirus disease 2019 (COVID-19) pandemic impacted children's lifestyle. To our knowledge, this is the first study that assesses the impact of quarantine on physical activity, screen time, sleep, and diet in children aged 5 to 12 in Qatar.

Methods

Cross-sectional data from an online survey distributed in Qatar was analyzed. The survey measured the parents' or caregivers' assessment on the change in the child's physical activity, sleep, screen time, and diet between the two periods (before quarantine and during quarantine). The data was analyzed using frequency distributions, paired t-test and McNemar's test.

Results

Data from 144 respondents were analyzed. Due to the quarantine, the total weekly average hours of physical activity significantly decreased with a greatest reduction for the school and after school durations. Only 4.5% of the children were engaging in at least 60 minutes of physical activity per day (in contrast to 25.6% prior to quarantine). The reported barriers for physical activity were screen time for school (52.8%) and leisure (51.4%). There was a significant increase in the total number of main meals per day, with a higher consumption of unhealthy food. The majority of the children had their bedtime and waketime shifted to later because of the quarantine. The parents' or caregivers' satisfaction with the child's lifestyle during quarantine showed that 49.1% were disappointed or very disappointed. Also, 53.8% described their child's mental health as “better before quarantine.”

Conclusions

Quarantine had a negative impact on the lifestyle of children in Qatar. When implementing restrictions, authorities should consider some interventions to counterpart such impact.

Sleep and Health-Related Characteristics among Adolescents during COVID-19: An Update

Two opposing effects on adolescents' health during COVID-19 lockdown have been described: A beneficial one due to longer sleep times during school closures and a detrimental one of psychological distress. This study investigated how sleep and health changed in the course of the pandemic when schools were open again. Overall, 12,238 adolescents in Switzerland participated in three cross-sectional online surveys: In 2017 under regular conditions (control group), during pandemic school closures in 2020 (closure group), and in 2021 still under pandemic conditions, but schools were open again (postclosure group). Sleep behavior and health-related characteristics (health-related quality of life; caffeine, alcohol, and nicotine use) in all three groups and depressive symptoms in the closure and postclosure groups were assessed. The sleep period on school days was longer in the closure group (median 9.00 h, interquartile range 8.25-9.75) and similar in the postclosure (7.92, 7.00-8.50) compared to the control group (7.75, 7.08-8.33). Health-related characteristics were better during school closures and similar to worse in the postclosure compared to the control group. Depressive symptom levels were higher in the postclosure than in the closure group. Therefore, beneficial effects were specific to school closures and adolescents' psychological distress increased over the course of the pandemic.

Social and environmental effects of the COVID-19 pandemic on children

OBJECTIVE

This study aimed to review the literature, summarizing the existing evidence on the effects of the pandemic on children, adolescents and parents, with an emphasis on the psychological, emotional, and sleep quality consequences.

SOURCE OF DATA

Empirical studies identified in the following databases: MEDLINE, ISI Web of Knowledge/Web of Science, and preprint servers.

SYNTHESIS OF DATA

The findings point to a wide range of consequences for children and adolescents resulting from the COVID-19 pandemic, which mainly includes an increase in depressive mood symptoms. There is also an increase in anxiety symptoms, suicidal ideation, as well as potential delays in language and motor development resulting from deprivation of social interaction and the closing of schools. These effects are more severe due to previous neuropsychiatric conditions. For parents, there is an increase in anxiety, depressive and post-traumatic symptoms, which are more accentuated in those who suffered socioeconomic damage due to the pandemic. There was an important increase in situations of violence towards children by parents and caregivers during the pandemic. Also, changes in routine and fear of the pandemic have negatively impacted sleep quality, globally.

CONCLUSIONS

It is noteworthy that most studies published to date used a cross-sectional design and applied online screening questionnaires. The few studies with a longitudinal design suggest that these changes may have been transitory and more prevalent at the beginning of the pandemic.

Happier during lockdown: a descriptive analysis of self-reported wellbeing in 17,000 UK school students during Covid-19 lockdown

Relatively little research has focused on children and young people (CYP) whose mental health and wellbeing improved during Covid-19 lockdown measures. We aimed to (1) determine the proportion of CYP who self-reported improvement in their mental wellbeing during the first Covid-19 lockdown and (2) describe the characteristics of this group in relation to their peers. We conducted a descriptive analysis of data from the 2020 OxWell Student Survey, a self-report, cross-sectional survey of English CYP. A total of 16,940 CYP primarily aged 8-18 years reported on change in mental wellbeing during lockdown. We characterised these CYP in terms of school, home, relational, and lifestyle factors as well as feelings about returning to school. One-third (33%) of CYP reported improved mental wellbeing during the first UK national lockdown. Compared with peers who reported no change or deterioration, a higher proportion of CYP with improved mental wellbeing reported improved relationships with friends and family, less loneliness and exclusion, reduced bullying, better management of school tasks, and more sleep and exercise during lockdown. In conclusion, a sizeable minority of CYP reported improved mental wellbeing during lockdown. Determining the reasons why these CYP felt they fared better during lockdown and considering how these beneficial experiences can be maintained beyond the pandemic might provide insights into how to promote the future mental health and wellbeing of school-aged CYP. All those working with CYP now have an opportunity to consider whether a systemic shift is needed in order to understand and realise any learnings from experiences during the pandemic.

Effects of COVID-19 home confinement on sleep in children: A systematic review

Our main aim was to examine the evidence of the effects of coronavirus disease confinement on the sleep of children aged 12 years and younger. A systematic review was conducted following the recommendations for Preferred Reporting Items for Systematic Reviews and Meta-Analyses. MEDLINE, Cumulative Index for Nursing and Allied Health Literature, Excerpta Medica Database, Psychological Information Database, and Web Of Science were systematically searched between the period of January 2020 and March 2021. The quality assessment was analysed with the Newcastle–Ottawa quality assessment scale and the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. The appraisal tool for cross-sectional studies was applied to cross-sectional studies and each longitudinal study was assessed with the critical appraisal skills programme. Data analysis was carried out through a narrative review. Eight studies were included in the review. Seven studies reported changes in sleep routines and five studies focused on sleep disturbances during confinement. The most important findings were a longer duration of sleep time, an increase in sleep latency, and daytime sleepiness. Whether or not the adverse changes to sleep patterns and bedtime routines seen during the home confinement period have any long-term consequences for children's sleep and daytime functioning remains unknown.

Sleep of infants and toddlers during 12 months of the COVID-19 pandemic in the midwestern United States

STUDY OBJECTIVES

Cultural sleep practices and COVID-19 mitigation strategies vary worldwide. The sleep of infants and toddlers during the COVID-19 pandemic in the United States (US) is understudied.

METHODS

Caregivers of children aged <3 years responded to a cross-sectional survey during 2020 (divided into quarters, with year quarter 1 largely pre-lockdown). We assessed the global effect of year quarter on parent-reported total sleep time (TST, hours) and sleep onset latency (SOL, hours) using ANOVA. We used multivariable linear regression to assess the adjusted effect of year quarter on TST, SOL and parental frustration. We used logistic regression to assess the adjusted effect of year quarter on nap consistency.

RESULTS

Of 594 children, mean age was 18.5±9.7 months; 52% were female. In the adjusted analyses, the reference categories were: quarter 1 (year quarter); ≤6 months (age category); <$25,000 (household income). TST was associated with age category (12 to ≤24 month: β=-2.86;p=0.0004, 24 to ≤36 month: β=-3.25;p<0.0001), and maternal age (β=-0.04;p=0.05). SOL was associated with year quarter (year quarter 3: β=0.16; p =0.04), age category (24 to ≤36 months: β=0.28;p<0.0001), household income ($100,000-150,000: β =-0.15;p=0.03, >$150,000: β=-0.19;p=0.01) and lack of room sharing (β=-0.09; p=0.05). Parental frustration with sleep increased with age (all p<0.05) and lack of room sharing (p=0.01). The effect of lack of room sharing on nap consistency approached significance (aOR 1.88;95%CI 0.95, 3.72).

CONCLUSIONS

Social factors such as lower household income and room sharing affected the sleep of US infants and toddlers as opposed to the COVID-19 lockdown itself.

Association Between Homeschooling and Adolescent Sleep Duration and Health During COVID-19 Pandemic High School Closures

IMPORTANCE

Although negative associations of COVID-19 pandemic high school closures with adolescents' health have been demonstrated repeatedly, some research has reported a beneficial association of these closures with adolescents' sleep. The present study was, to our knowledge, the first to combine both perspectives.

OBJECTIVE

To investigate associations between adolescents' sleep and health-related characteristics during COVID-19 pandemic school closures in Switzerland.

DESIGN, SETTING, AND PARTICIPANTS

This survey study used cross-sectional online surveys circulated among the students of 21 public high schools in Zurich, Switzerland. The control sample completed the survey under regular, prepandemic conditions (May to July 2017) and the lockdown sample during school closures (May to June 2020). Survey respondents were included in the study if they provided their sex, age, and school.

EXPOSURES

High school closures during the first COVID-19 pandemic wave in Switzerland (March 13 to June 6, 2020).

MAIN OUTCOMES AND MEASURES

Sleep-wake patterns, health-related quality of life (HRQoL, assessed by the KIDSCREEN-10 questionnaire), substance use (caffeine, alcohol, and nicotine), and depressive symptoms (lockdown sample only; assessed using the withdrawn/depressed scale from the Youth Self Report). Multilevel regression models were used to assess sample differences and associations of health-related characteristics with sleep duration and depressive symptoms.

RESULTS

The total sample consisted of 8972 students, including 5308 (59.2%) in the control sample (3454 [65.1%] female) and 3664 (40.8%) in the lockdown sample (2429 [66.3%] female); the median age in both samples was 16 years (IQR, 15-17 years). During school closures, the sleep period on scheduled days was 75 minutes longer (semipartial R2 statistic [R2β*], 0.238; 95% CI, 0.222-0.254; P < .001) and the students had better HRQoL (R2β*, 0.007; 95% CI, 0.004-0.012; P < .001) and less consumption of caffeine (R2β*, 0.010; 95% CI, 0.006-0.015; P < .001) and alcohol (R2β*, 0.014; 95% CI, 0.008-0.022; P < .001). Longer sleep duration was associated with better HRQoL (R2β*, 0.027; 95% CI, 0.020-0.034; P < .001) and less caffeine consumption (R2β*, 0.013; 95% CI, 0.009-0.019; P < .001). In the lockdown sample, an inverse association was found between depressive symptoms and HRQoL (R2β*, 0.285; 95% CI, 0.260-.0311; P < .001) and a positive association was found with caffeine consumption (R2β*, 0.003; 95% CI, 0.000-0.008; P = .01).

CONCLUSIONS AND RELEVANCE

In this survey study, 2 opposing associations between school closures and adolescents' health were identified: a negative association with psychological distress and a beneficial association with increased sleep duration. These findings should be considered when evaluating and implementing school closures. Furthermore, the findings provide support for delaying school start times for adolescents.

Perceived changes in lifestyle behaviours and in mental health and wellbeing of elementary school children during the first COVID-19 lockdown in Canada

OBJECTIVES

The closure of schools to prevent the spread of COVID-19 prompted concerns of deteriorating lifestyle behaviours, mental health, and wellbeing of children, particularly those in socioeconomically disadvantaged settings. We assessed changes in lifestyle behaviours (physical activity, screen time, eating habits and bed/wake-up times), mental health and wellbeing during the first lockdown in Spring 2020 as perceived by school children from disadvantaged settings, and examined determinants of these changes.

STUDY DESIGN

Cross-sectional study.

METHODS

We surveyed 1095 grade 4 to 6 students (age 9-12 years) from 20 schools in socioeconomically disadvantaged communities in northern Canada. Students reported on changes in lifestyle behaviours, mental health and wellbeing during the lockdown. Determinants of these perceived changes were examined in multivariable regression models.

RESULTS

A majority of students reported declines in physical activity, having late bed/wake-up times, and modest improvements in mental health and wellbeing. Many students reported increases rather than decreases in screen time and snacking. Positive attitudes toward being active, eating healthy, going to sleep on time and being healthy were strongly associated with maintaining healthy lifestyle behaviours during the lockdown. Positive attitudes toward active and healthy living and healthy lifestyle behaviours were associated with maintaining positive mental health and wellbeing during the lockdown.

CONCLUSIONS

The considerable changes in lifestyle behaviors, superimposed on the pre-existing burden of unhealthy lifestyle behaviours, put this generation of children at increased risk for future chronic disease. Findings call for effective health promotion of active and healthy lifestyles to benefit both physical and mental health.

The impact of COVID-19 lockdown on sleep patterns, emotions, and behaviors of children and adolescents in Taiwan

BACKGROUND

The lockdown in May 2021 was the first and only lockdown implemented in Taiwan during the COVID-19 pandemic. The epidemic in Taiwan has been maintained under relatively better control and this study aimed to examine the impact of the lockdown on sleep and emotional and behavior disturbances in children and adolescents in Taiwan.

MATERIAL AND METHODS

Participants over 6 years old were recruited retrospectively from a cohort study, and their parents completed questionnaires including the Children's Sleep Habits Questionnaire (CSHQ), the Child Behavior Checklist (CBCL), the Swanson, Nolan and Pelham-IV Teacher and Parent Rating Scale (SNAP-IV), and the function assessment. A total of 217 children and adolescents whose parents completed questionnaires during both the lockdown period and the pre-lockdown period were included. We used paired t-test and independent t test; to analyze the differences between the lockdown and pre-lockdown periods and between different subgroups.

RESULTS

The mean age of all participants was 11.87 ± 3.97 years, with 69.6% male. The results of CSHQ indicated that our participants had significantly increased total sleep time (p = 0.000), more sleep onset delay (p = 0.011), fewer sleep duration problems (p = 0.029), less parasomnia (p = 0.018), fewer sleep breathing problems (p = 0.028), and less daytime sleepiness (p = 0.000) during the lockdown, especially males and children. We observed trends but no significant changes of all participants in CBCL and SNAP during the lockdown. The change of the inattention index reached a significant level between children and adolescents (p ² = 0.017). The results of the functional assessment showed more interferences in home living (p = 0.021) of all participants, especially males (p ¹ = 0.002).

CONCLUSIONS

The lockdown significantly impacted children and adolescents' sleep and functioning. We also observed trends of increased emotion, behavior and inattention problems, and significantly increased interference in home living. Male gender and younger age may be associated factors for sleep and functional disturbances of the lockdown.

Impact of COVID-19 pandemic lockdown on movement behaviours of children and adolescents: a systematic review

INTRODUCTION

Several studies have examined how the lockdown restrictions enforced to halt the spread of COVID-19 have affected children and adolescents' movement behaviours, but there is a need to synthesise these findings. Therefore, we conducted this systematic review to examine the impact of COVID-19 lockdown on children and adolescents' movement behaviours.

METHODS

We searched eight databases and grey literature for relevant studies of all study designs; and conducted a narrative analysis of the results following synthesis without meta-analysis guidelines. We used appropriate tools to assess the risk of bias in quantitative and qualitative studies. We compared changes in physical activity, screen time and sleep duration and quality from before to during the COVID-19 lockdown.

RESULTS

This review included 71 studies reporting data from 35 countries and territories, mostly from high-income economies. A majority of the studies used a cross-sectional design and had fair to poor-quality ratings. Most studies reported reduced physical activity, increased screen time and longer sleep hours among children and adolescents. Children and adolescents facing strict lockdowns saw a larger decline in physical activity and a sharper increase in screen time than those under mild restrictions.

CONCLUSION

COVID-19-related lockdowns were detrimental to children and adolescents' movement behaviours, with stricter lockdowns tending to have a bigger impact. Children and adolescents under COVID-19 restrictions are likely to be less active, spend more time on screen, and sleep longer hours than before the lockdown. More studies from low-income and middle-income countries could provide a clearer picture of the impact.

Learning Methods During School Closure and Its Correlation With Anxiety and Health Behavior of Thai Students

BACKGROUND

The sequential waves of epidemic spread of COVID-19 in Thailand have caused periodic closures of schools, and exposed students to different learning methods that require multiple adjustment strategies. This study aimed to examine how different learning methods may correlate with anxiety and health behavior (e.g., physical activity, active play, screen time, sleep) of primary and secondary school students in Thailand.

METHODS

Thailand Report Card (TRC) Data (2021) was employed. The sample of the TRC was drawn by multi-stages random sampling stratified by region, district, urban/rural, school size, sex, and age to ensure national representativeness. A total of 6,078 Thai primary (64%) and secondary (36%) school students were included in the analysis.

RESULTS

About two-thirds (66.4%) of the sample experienced a shift from traditional classroom to fully online learning, 6.9% experienced partial online instruction, 23.6% received handouts or written assignments, and 3.1% resumed traditional classroom learning. Compared to fully online learning, students who experienced traditional classroom (onsite) teaching were 37.8% less likely to report moderate-to severe anxiety (OR 0.6; p-value 0.021). There was no significant correlation between school closure-induced anxiety with overall physical activity (PA) and active play, but anxiety was significantly associated with screen time and sleep duration. Receiving handouts/written assignments only as the learning method was significantly correlated with PA, but two methods (handouts and onsite/traditional classroom) was significantly correlated with active play. Students who experienced classroom learning were also more likely to comply with recommended durations of screen time and sleep.

CONCLUSION

Although online learning was probably the most convenient choice during COVID-19 containment measures in Thailand, this method did not provide sufficient opportunity for PA and play. Online learning also encouraged an excessive use of screen media, and disrupted sleeping patterns. Online learning also pressured Thai students to make various adjustments in their daily routines that may have further aggravated anxiety.

Adolescent sleep health and school start times: Setting the research agenda for California and beyond: A research summit summary: A research summit summary

In fall 2019, California passed and signed into law SB328, the first US statewide legislation explicitly designed to protect adolescent sleep health by requiring most California public school districts to start no earlier than 8:00 AM for middle schools and 8:30 AM for high schools. Recognizing the unique opportunity presented by the bill's 3-year implementation period, a group of experts in adolescent sleep and school start times held a virtual summit on January 22-23, 2021 to (1) summarize the research on adolescent sleep and school start time change; (2) develop recommendations for relevant, refined, and innovative research areas and research questions; (3) provide input regarding research design, methodology, and implementation; and (4) offer a forum for networking, exchanging ideas, and establishing interdisciplinary research collaborations. Participants represented a multidisciplinary range of academic backgrounds including sleep and circadian biology, neuroscience, education, medicine, public health, mental health, safety, public policy, economics, implementation science, criminology, diversity studies, and science communication. This paper summarizes summit presentations regarding current knowledge on adolescent sleep health and school start times and key research recommendations from small group workshops on topics including research design and tools, methodological issues, sleep health disparities, logistical challenges in conducting school-based research, public-health impact, and novel and expanded approaches to research.

Teachers' preference for later school start times

Early morning school start times conflict with biologically determined sleep phase preference and thus contribute to common sleep deficits. This conflict is most pronounced in adolescents, and numerous studies have confirmed that later school start times are beneficial for their sleep and health. However, the conflict continues to exist beyond adolescence and, accordingly, also teachers might benefit from later school start times, but this has gained little attention so far. Importantly, teachers’ resistance to delay school start time is one of the key barriers for a successful implementation and, therefore, teachers’ school start time preferences and influencing factors are important to consider. To this end, we conducted an online survey. Teachers (n = 694, 56.1% female) from 17 high schools in Zurich, Switzerland, participated in the study. They indicated their school start time preference. In addition, four predictor blocks were assessed: sociodemographic, school‐/work‐related, and sleep characteristics, as well as teachers’ perception of students in the first morning lesson. Mixed models were applied to predict the preference. The majority (51%) endorsed later school start times (median preferred delay 25.2 min). School start time, sleep characteristics and perception of students in the first morning lesson were significant predictors for the preference. Thus, teachers with more misaligned sleep and higher awareness for students’ issues in the early morning were more likely to report a preference. This suggests psychoeducation about sleep biology throughout life span to be an effective measure to increase teachers’ support to delay school start time, especially because also they themselves are likely to benefit from later school start times.
