The Influencing Factors of Sleep Quality Among Chinese Junior and Senior High School Adolescents During the COVID-19 Pandemic

Associations between capacity of cognitive control and sleep quality: a two-wave longitudinal study

This longitudinal study explored the impact of the upper limit of cognitive control on the sleep quality of high school students. We collected data in two waves to examine four main variables: capacity of cognitive control (CCC), trait mindfulness, emotional distress and sleep quality. At the first time point (T1), trait mindfulness and emotional distress were measured by rating scales, and the CCC was evaluated by revised backward masking majority function task. Sleep quality was rated 5 months later (T2). The results indicated that: (1) the CCC was negatively correlated with trait mindfulness, and trait mindfulness was negatively correlated with emotional stress; (2) there was no simple mediation of either trait mindfulness or emotional distress in the relationship between CCC and sleep quality; (3) instead, the CCC was associated with poor sleep quality in a sequential mediation through trait mindfulness and then emotional stress. The research highlights the importance of trait mindfulness and emotional distress for addressing sleep problems in adolescents.

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.

Autopercepção Negativa de Saúde em Adolescentes durante a Pandemia de Covid-19 e Fatores Associados

O objetivo deste estudo foi analisar a prevalência da autopercepção negativa de saúde de adolescentes durante a pandemia de covid-19 e fatores associados. Trata-se de um estudo descritivo de corte transversal, realizado com 287 adolescentes. Foram avaliadas questões referentes à autopercepção de saúde, ao perfil sociodemográfico e aos fatores comportamentais. As razões de prevalência (RP) e os intervalos com 95% de confiança (IC95%) foram estimados por meio de modelos múltiplos de regressão de Poisson. A prevalência de autopercepção negativa de saúde foi observada em 31,0% dos adolescentes. Observou-se que a imagem corporal (RP = 1,14; IC95%:1,05-1,23), a prática de atividade física (RP = 1,12; IC95%:1,03-1,21), a qualidade do sono (RP = 1,17; IC95%:1,08-1,28) e o consumo de frutas (RP = 1,18; IC95%:1,07-1,30) mostraram-se associados à autopercepção negativa de saúde dos adolescentes. Conclui-se que, durante a pandemia de covid-19, foi observada alta prevalência de autopercepção negativa da saúde. Ademais, a insatisfação com a imagem corporal, a prática de atividade física insuficiente, a qualidade do sono ruim e o consumo de frutas afetaram a autopercepção de saúde dos adolescentes.

Prevalence of mental health symptoms in children and adolescents during the COVID-19 pandemic: A meta-analysis

The COVID-19 pandemic and its accompanying infection control measures introduced sudden and significant disruptions to the lives of children and adolescents around the world. Given the potential for negative impacts on the mental health of youths as a result of these changes, we conducted a systematic review and meta-analysis to examine the prevalence of depressive symptoms, anxiety symptoms, and sleep disturbances in children and adolescents during the pandemic. We searched major literature databases for relevant cross-sectional or longitudinal studies that included primary and secondary school students or children and adolescents ≤18 years of age. Prevalence values were extracted, logit-transformed, and pooled. Based on 191 included studies with 1,389,447 children and adolescents, we found the pooled prevalence of depressive symptoms, anxiety symptoms, and sleep disturbances to be 31%, 31%, and 42%, respectively. Age, grade levels, education levels, gender, geographical regions, and electronics use were correlated with the prevalence of mental health symptoms. The prevalence of mental health symptoms also increased with time, although signs of recovery and stabilization were also observed. Overall, the results from this review demonstrate the need for increased mental health research, monitoring, and intervention for children and adolescents during the current and future pandemics.

Physical activity, sleep quality and life satisfaction in adolescents: A cross-sectional survey study

Background

Physical activity, sleep is an important component of adolescents' 24-h movement behavior, and life satisfaction predicts adolescent physical and mental health. However, few studies have explored the relationship between the two variables among Chinese high school students. Consequently, this study aimed to explore the relationship between sleep quality and life satisfaction among Chinese high school students.

Methods

This cross-sectional study was conducted in October 2020 in five high schools in Xuchang City, China. High school students from senior 1 to senior 3 were asked to fill up a questionnaire of demographic characteristics and validated screen instructions for sleep quality (Pittsburgh Sleep Quality Index) and life satisfaction (Satisfaction with Life Scale). The multivariate regression model was applied to explore the association between sleep quality and life satisfaction.

Results

A total of 1127 individuals (51.1% males) participated in this survey, and the prevalence of poor sleep quality was 42.3%. The mean score on the Satisfaction with Life Scale was 16.72 ± 5.67, according to the corresponding scoring criteria, with 15-19 being generally dissatisfied. After controlling for demographic variables, the contribution of subjective sleep quality (β = - 0.181, p < 0.01), sleep duration (β = - 0.080, p < 0.01) and daytime dysfunction (β = - 0.311, p < 0.01) to life satisfaction of high school students increased to 23.2%, indicating that subjective sleep quality, sleep duration, and daytime dysfunction were 22.9% predictive of life satisfaction among high school students. And also, physical activity on schooldays and weekend days were associated with better sleep quality and higher life satisfaction (p < 0.05).

Conclusions

Among Chinese high school students, the prevalence of sleep problems was high, and the majority of students held moderate life satisfaction. Sleep quality was positively correlated with life satisfaction among Chinese high school students, with better sleep quality resulting in higher life satisfaction among students.

Mapping network connection among symptoms of anxiety, depression, and sleep disturbance in Chinese high school students

Background

Due to tremendous academic pressure, Chinese high school students suffer from severe depression, anxiety, and sleep disturbances. Moreover, senior high school students commonly face more serious mental health problems than junior high school students. However, the co-occurrence and internal relationships of depression, anxiety, and sleep disturbances clusters are scarcely examined among high students. Therefore, the current study inspected relationships between depression, anxiety, and sleep disturbance symptoms through network analysis and identified key symptoms bolstering the correlation and intensifying the syndromes.

Methods

A total of 13,999 junior high school students (M _age = 13.42 years, SD _age = 1.35, 50% females) and 12,550 senior high school students (M _age = 16.93 years, SD _age = 1.67, 47% females) were recruited in Harbin. We constructed networks for all students, junior high group, and senior high group, including data from the Youth Self-rating Insomnia Scale-3 (YSIS-3), the Generalized Anxiety Disorder-2 (GAD-2), and the Patient Health Questionnaire-2 (PHQ-2). The indices of "strength" was used to identify symptoms' centrality, and "bridge strength" was used to find specific nodes that could bridge anxiety, depression, and sleep disturbance.

Results

The networks of all students, junior high and senior high students, were stable and accurate. Among all networks, "Nervousness" (GAD1) had the highest strength, and "Nervousness"-"Excessive worry" (GAD1-GAD2) had the strongest correlation. "Nervousness" (GAD1) also functioned as the bridge symptom among junior high students, while "Sad mood" (PHQ2) among senior high students. Senior high students scored higher than junior high students on all items and had a tighter network structure.

Conclusions

In networks consisting of anxiety, depression, and sleep disturbance, anxiety plays a conspicuous role in comorbidity among junior high school students, which transforms into depression among senior high school students. Treatments or interventions should be focused on these critical symptoms.

Association between quality of sleep and screen time during the COVID-19 outbreak among adolescents in the United Arab Emirates

The COVID-19 pandemic had a major impact on people of all ages. Adolescents' exposure to online learning is linked to excessive screen time on digital devices, which leads to poor sleep quality. This study aimed to investigate the association between screen time on different electronic devices and sleep quality among adolescents in the United Arab Emirates. This study was based on a self-reported questionnaire, which was administered online to school-aged adolescents (aged 12-19 years). The multicomponent questionnaire collected information on sociodemographic characteristics, sleep quality using the Pittsburgh Sleep Quality Index (PSQI), and screen time (minutes) on TV, TV-connected devices, laptops, smartphones, and tablets on weekdays, weeknight, and weekends using the Screen Time Questionnaire (STQ). Univariate and multivariate analyses were used to identify factors correlated with poor sleep quality. A total of 1720 adolescents were recruited from private and public schools (mean age 14.6 ± 1.97 years). The mean PSQI score was 8.09 ± 3.37, and 74.3% of participants reported poor sleep (cutoff score >5). Mean scores were highest for the sleep latency (1.85 ± 0.97) and sleep disturbance (1.56 ± 0.62) domains. The highest STQ score was observed for smartphones, with a median screen time of 420 min on weekdays and 300 min on weekends. Screen time related to smartphones on weekends (p = 0.003) and increased screen time in bed (p < 0.001) were significantly associated with poor sleep. Our results confirmed the correlation between sleep and screen time in adolescents. The results may inform educational polices that target screen time and sleep among adolescents during and after the COVID-19 pandemic.

A narrative review into the impact of COVID-19 pandemic on senior high school adolescent mental health

Problem

High school teenagers are facing significant challenges during the COVID‐19 pandemic. Teenagers are at risk of experiencing physical, mental, and social health problems due to the COVID‐19 pandemic. This narrative review aims to explore the impact of COVID‐19 on the emergence of mental health problems in high school adolescents.

Methods

This study employed a narrative review method. We conducted a systematic search using PRISMA on three databases: Medline, PubMed, and ScienceDirect. A total of 40 articles met the inclusion and exclusion criteria set based on the research objectives.

Findings

The study uncovered that high school adolescents had an increased risk of experiencing mental health problems, namely psychological distress, worry, loneliness, anxiety, depression, traumatic symptoms, other psychological disorders, suicide risk, sleep disorders, and psychosocial functioning. Anxiety, depression, and psychological stress were the most discussed mental health problems among high school adolescents during the COVID‐19 pandemic.

Conclusions

There is a need for efforts to identify health problems and intervene in mental health problems early in high school adolescents. Schools, mental health workers, and the government (e.g., policy stakeholders) need to implement the recommendations given as a follow‐up effort for mental health services for high school youth.

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.
