Late use of electronic media and its association with sleep, depression, and suicidality among Korean adolescents

Predictors of sleep modifiable factors and the correlation with non-suicidal self-injury: the important role of problematic mobile phone use and mental health

BACKGROUNDS

Non-suicidal self-injury (NSSI) has long affected people's lives and is an important and serious public health issue, especially among college students. This study aims to identify modifiable factors, including problematic mobile phone use (PMPU) and mental health (MH), etc. Only a few studies have mentioned the correlation between PMPU and NSSI, this study focus on its association with suicide, and whether this association is moderated by chronotype and MH needs to be confirmed by research.

METHODS

A cross-sectional study design investigated the association between PMPU, chronotype and MH and NSSI. We collected information from participants using an electronic questionnaire that included general demographics, PMPU, NSSI, and sleep-related variables (chronotype, weekday and weekend sleep duration). Participants completed standardized questionnaires, including mobile phone addiction tendency scale (MPATS) for PMPU, the Morningness-Eveningness Questionnaire (MEQ) for chronotype, Patient Health Questionnaire (PHQ-9) for depression symptoms, Generalized Anxiety Scale (GAD-7) for anxiety symptoms, and the non-suicidal self-injury (NSSI) for suicide risk. A multivariable linear regression model measure these variables, and moderation model which using the PROCESS method examined the relationship of PMPU, chronotype and MH and NSSI.

RESULTS

A total of 5639 adolescents were included in the study, with a mean age of 19.64 [± 0.90] years), and 46.3% of the participants were male. The prevalence of NSSI was 12.1%, in multivariate linear regression, high levels of PMPU (β = 0.362), eveningness (β = 0.665), depression (β = 1.183), and anxiety (β = 1.308) were all associated with higher NSSI, indicating a significant association. In the analysis results of moderation, chronotype and MH also moderated the relationship between PMPU and NSSI, indicating that there was a relationship between PMPU, chronotype, MH and NSSI.

CONCLUSIONS

This study highlights the important role of PMPU and mental health in predicting NSSI. Interventions targeting these modifiable factors may help reduce the prevalence of NSSI among young adults. Improving sleep hygiene, reducing mobile phone abuse, and providing appropriate psychological support are effective strategies to prevent NSSI. Educational institutions and society should strengthen guidance on the proper use of digital media by young people, especially among college students, promote healthy lifestyles, and establish early identification and support systems to help those individuals at risk.

Assessment of indoor light-at-night exposure in children and adolescents during schooldays and weekends

Light-At-Night (LAN) is increasingly recognized and may has adverse health effects on children and adolescents, yet few studies have reported objective indoor LAN exposure levels for children and adolescents. In this study, we measured the indoor LAN exposure levels and duration among 897 children and adolescents aged 6-14 in Beijing, China, using portable photometers during both school days and weekends. Results indicate that the median indoor LAN exposure from 9:00 p.m. to 7:00 a.m. was 5.1 lx, with 31.8% of the subjects experiencing an average exposure above 10 lx. Additionally, from the perspective of cumulative high exposure duration, children and adolescents were exposed to more than 10 lx for approximately 64 min from 9:00 p.m. to 7:00 a.m. During the entire nighttime (from self-reported bedtime to wake-up time), the median exposure was 2.1 lx, with 16.6% averaging exposures above 10 lx. Exposure levels were significantly higher on weekends than on schooldays. Both girls and upper-grade students had higher levels of exposure and longer durations of high exposure. Girls in grade 7 (OR:2.56, 95%CI: 1.68-3.88) experienced the highest LAN exposure in our subjects compared to boys in grade 1-4. Our findings underscore the importance of promoting healthy light exposure behaviors among children and adolescents and reducing their light exposure environments to mitigate the potential health impacts of LAN.

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.

Korean autistic persons facing systemic stigmatization from middle education schools: daily survival on the edge as a puppet

Introduction

Korean autistic persons who have endured an integrated secondary education system have been exposed to school bullying, causing trauma and stigma to them. It also blocks them from entering a tertiary education system and a decent work, resulting in a lower quality of life. However, research on how it affects autistic persons has not yet been conducted in Korea.

Methods

Fourteen adult autistic persons in the Republic of Korea participated in the semi-structured focused group interviews. Their conversations were analyzed through qualitative coding.

Results

The interview results show the rare voice of Korean autistic people. Although interviewees experienced physical, verbal, and sexual violence against them during the secondary education period, they could not get substantial assistance from schools and society. Interviewees agreed that bullying is inherent in the secondary education system of Korea, even in Korean culture. They experienced the cause of bullying being attributed to them as victims rather than perpetrators, and impunity is given to the bullying assailants. Early analyses of this article confirm that such experiences are combined with the sociocultural climate of elitism, meritocracy, and authoritarianism in the Republic of Korea.

Conclusion

The study confirmed that the autistic person's bullying experience does not come from the social inability of autistic people but the "profound" competition and discriminative atmosphere of the society. The result urges further studies on the bullying experience of East Asian autistic persons and the construction of Korean intervention strategies to prevent school violence against Koreans with disabilities, especially autistic pupils.

Problematic internet use and suicide ideation among Chinese adolescents: The indirect effects of insomnia, nightmares, and social jetlag

BACKGROUND

Problematic Internet use (PIU) is related to suicide ideation (SI) in adolescents, but little is known about the potential mechanisms between them. This study aimed to examine the mediation roles of insomnia, nightmares, and social jetlag in the association of PIU with SI in adolescents.

METHODS

A total of 39,731 adolescents (mean age = 13.49 ± 0.76 years, 54.4 % males) from Shenzhen, China, participated in a cross-sectional survey. SI was assessed using the ninth item of the Patient Health Questionnaire-9. PIU was measured by the Revised Chinese Internet Addiction Scale. A self-administered questionnaire was used to assess insomnia symptoms, nightmare frequency, social jetlag, sleep duration, psychological distress, and social-demographical characteristics. Logistic regression and path analyses were performed to examine the associations between PIU, insomnia symptoms, nightmares, social jetlag, and SI.

RESULTS

The prevalence of PIU and SI were 14.9 % and 18.6 %, respectively. PIU, insomnia symptoms, frequent nightmares, and social jetlag were significantly associated with SI. Path analyses showed that the indirect effects of PIU on SI through insomnia symptoms, frequent nightmares, and social jetlag were significant. Conversely, social jetlag significantly mediated the pathway from SI to PIU. The mediation effect sizes of these sleep and circadian problems were slightly larger in females than in males.

LIMITATIONS

Cross-sectional design limited the capacity to infer causal relationships.

CONCLUSIONS

The associations between PIU and SI were mediated by sleep and circadian problems. These findings underscore the importance of assessing and intervening in sleep and circadian problems among adolescents with PIU or SI.

Moderation effects of health behaviors on stress and suicidal ideation in adolescents: a cross-sectional survey during COVID-19

This cross-sectional online survey study investigated whether certain health behaviors moderated the relationship between perceived stress and suicidal ideation in Austrian adolescents during the COVID-19 pandemic. A total of 1505 14-20-year-old (median age = 16) high school students (77.9% female) filled out an online survey from September to November 2021. Perceived stress was measured with the PSS10, suicidal ideation with item 9 of the PHQ-9. The following health behaviors were assessed: Physical activity (days/week), phone use (hours/day), problematic drinking behavior (CAGE). All three health behaviors significantly moderated the relationship between perceived stress and suicidal ideation (all p < .05), but effects were small. The moderation analyses revealed that higher physical activity and less time spent on the phone were associated with less suicidal ideation at higher stress levels. Showing signs of problematic drinking behavior was associated with higher suicidal ideation at higher stress levels. In conclusion, these results suggest that some health behaviors may be able to act as a buffer between perceived stress and suicidal ideation. However, more research is needed to confirm these potentially buffering effects.

Six-year trends and intersectional correlates of meeting 24-Hour Movement Guidelines among South Korean adolescents: Korea Youth Risk Behavior Surveys, 2013-2018

BACKGROUND

Grounded in intersectionality theory, this study examined the 6-year prevalence trend and correlates in meeting Canada's 24-Hour Movement Guidelines (Guidelines hereafter) in a nationally representative adolescent samples of South Korea (officially the Republic of Korea).

METHODS

Self-reported, annually repeated cross-sectional data collected between 2013 and 2018 were used (n = 372,433, 12-17 years old, 47.9% females). Adolescents were categorized as meeting or not meeting different sets of physical activity, screen time (ST), and sleep recommendations within the Guidelines, separately for weekdays and weekend days. Intersectional correlates included sex and social class (i.e., family economic status, parental education level, and academic performance). Multiple logistic regression analyses were performed.

RESULTS

Overall, the proportion of adolescents meeting physical activity, ST, and sleep recommendations were 5.3%, 60.3%, and 10.2% on weekdays and 5.3%, 28.2%, and 46.4% on weekend days, respectively. Between 2013 and 2018, no substantial changes were observed for meeting the physical activity or sleep recommendation, while meeting the ST recommendation was markedly lower in 2018. The proportion of meeting all 3 recommendations were 0.5% for weekdays and 0.8% for weekend days. Overall, compared to female adolescents, male adolescents were consistently associated with more favorable patterns of meeting different sets of recommendations, regardless of social class. Among females only, social class appeared to be not important or even detrimental in meeting different sets of recommendations. Being male, compounded with social class, was associated with meeting the ST recommendation.

CONCLUSION

Less than 1% of Korean adolescents met the overall Guidelines. Intersectionality-based analysis and intervention may be important in promoting healthy active lifestyles among South Korean adolescents.

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

OBJECTIVES

Shiftworkers routinely obtain inadequate sleep, which has major health consequences. Sleep hygiene describes a range of behaviours, lifestyle and environmental factors that can improve sleep. To date, limited research has examined sleep hygiene in shiftworkers. This study aimed to assess the sociodemographic and behavioural correlates of sleep hygiene knowledge and engagement with sleep hygiene practices in Australian shiftworkers.

STUDY DESIGN

An online, cross-sectional survey.

SETTING AND PARTICIPANTS

Australian adults from across multiple industries (n=588) who work shift work.

MEASURES

The online survey included questions regarding sleep hygiene knowledge and questions from modified versions of the Pittsburgh Sleep Quality Index and Sleep Hygiene Index.

RESULTS

Of the 588 participants, 52.9% reported having heard of 'sleep hygiene'. Of these participants, 77.5% reported understanding the term moderately, extremely or very well. Engagement with each sleep hygiene practice was varied. Common sleep hygiene practices were controlling the bedroom environment (eg, a cool, dark and quiet bedroom). Less common practices were avoiding light as bedtime approaches. Logistic regressions revealed that shiftworkers who had heard of sleep hygiene were more likely to engage in sleep hygiene practices and had better sleep quality compared with those who had not heard of sleep hygiene. Increased engagement in sleep hygiene practices did not predict the likelihood of individuals reporting better sleep quality.

CONCLUSIONS

Shiftworkers demonstrated varied knowledge, understanding and engagement with individual sleep hygiene practices. Future research should focus on the development of sleep hygiene interventions that accommodate the unique challenges of shift work to optimise sleep.

The Associations of Electronic Media Use With Sleep and Circadian Problems, Social, Emotional and Behavioral Difficulties in Adolescents

BACKGROUND

Electronic media use (EMU) becomes one of the most common activities in adolescents. The present study investigated the deleterious influence of excessive EMU and EMU before bedtime on social, emotional, and behavioral difficulties (SEBD) in adolescents. The role of sleep and circadian problems in mediating the association of EMU with SEBD was examined.

METHODS

A cross-sectional survey study was conducted with 3,455 adolescents (55.7% female, mean age = 14.8 ± 1.57 years, 36.6% monthly family income < HK$15,000) between December 2011 and March 2012 in Hong Kong. The associations of EMU with sleep and circadian problems and SEBD were analyzed using multiple binary logistic regression and path analysis. Sleep problems were measured by the Insomnia Severity Index and the reduced Horne and Östberg Morningness and Eveningness Questionnaire. Circadian problems were calculated based on established formulas. SEBD was measured using the Strengths and Difficulties Questionnaire. Participants' mental health status was assessed by the General Health Questionnaire.

RESULTS

A longer duration of EMU, excessive EMU (daily duration ≥ 2 h), and bedtime EMU (an hour before bedtime) were associated with the risk of sleep and circadian problems, poor mental health, and SEBD (p < 0.05). Insomnia, eveningness, social jetlag, and sleep deprivation were found to mediate the associations of EMU (including bedtime EMU of computers, electronic game consoles, phones, and televisions, together with excessive EMU of computers for leisure purposes and phones) with mental health and SEBD.

CONCLUSIONS

The findings suggest the need for setting up guidelines and advocacy for education for appropriate EMU and intervention for the associated sleep and circadian problems to ameliorate EMU-related mental and behavioral health problems in adolescents.

The Associations between Sleep Duration, Academic Pressure, and Depressive Symptoms among Chinese Adolescents: Results from China Family Panel Studies

Depressive symptoms are a common mental health problem among adolescents, which may affect their physical and mental health development and impose heavy burdens on individual families and society. This study aimed to examine the associations between sleep duration, academic pressure, and depressive symptoms among Chinese adolescents and to construct the mediation model to explore the mediating effect of sleep duration. The data are from the China Family Panel Studies (CFPS). Methodologically, the aforementioned associations were explored by constructing a structural equation model and applying multivariate multilevel logistic regression. In this study, we found that approximately 6.49% of the 3724 Chinese adolescents had depressive symptoms. Sleep duration of <6 h/night (OR = 2.39, 95%CI = 1.33-4.32) and high/maximum academic pressure (high: OR = 1.43, 95%CI = 1.02-1.99; maximum: OR = 2.43, 95%CI = 1.58-3.73) were both associated with an increased risk of depressive symptoms in adolescents. Meanwhile, the multiplicative interaction between sleep duration and academic pressure was significantly associated with depressive symptoms in adolescents (p < 0.001). The sleep duration played a partial mediating role in the relationship between academic pressure and depressive symptoms (a*b = 0.006, 95%BootCI = 0.001-0.012). Our study highlights that it is essential to mitigate the academic pressure of adolescents to increase their sleep duration and further reduce the occurrence of depressive symptoms by adopting corresponding preventive measures.

What do people do before going to bed? A study of bedtime procrastination using time use surveys

STUDY OBJECTIVES

Bedtime procrastination (BP) is defined as going to bed later than intended despite absence of external reasons. This study investigated sleep and psychological factors associated with BP in young adults, and further compared how high and low BP groups spend their time over 24 h and also 3 h prior to bedtime using time use surveys.

METHODS

Young adults (N = 106) from the community were classified as either high (n = 54) or low (n = 52) BP group based on the Bedtime Procrastination Scale. All participants were asked to complete questionnaires on insomnia, depression, anxiety, stress, and chronotype, in addition to keeping a 7-day sleep diary and completing time use surveys over 48 h.

RESULTS

Participants were 61.3% female, mean age 22.7 (±2.89) years old. Individuals in the high BP group reported significantly more depression, anxiety, and insomnia, went to bed later, woke up later, and had more eveningness tendencies compared to the low BP group. Results from the time use surveys revealed that the high BP group spent significantly more time engaging in leisure and social activity with the majority of time spent using media over 24 h compared to the low BP group. Finally, the high BP group spent on average approximately 451% (or 61 min) more time per day on their smartphone 3 h prior to bedtime compared to the low BP group.

CONCLUSIONS

Our results suggest that BP is negatively associated with sleep and mood, and should be considered a serious health-interfering behavior.

Interplay between social media use, sleep quality, and mental health in youth: A systematic review

Social media applications are increasingly prominent among youth. This systematic review provides a comprehensive assessment of the literature on the relationship between active social media use, sleep quality, and common mental health outcomes (anxiety, depression, and psychological distress) among youth. MEDLINE, PsychINFO, EMBASE and Scopus were searched for observational studies investigating this relationship among youth (aged 16-25). Thirty-six cross-sectional studies and six prospective cohort studies met the inclusion criteria. Among cross-sectional studies, significant associations between excessive social media use with poor mental health outcomes (n = 33), poor sleep quality (n = 24), and significant associations between poor sleep quality and negative mental health (n = 16) were found. In longitudinal studies, frequent social media use was a risk factor for both poor mental health (n = 6) and poor sleep outcomes (n = 5). Some studies showed sleep quality mediating the relationship between social media use and negative mental health outcomes in youth. Overall, included evidence links excessive social media use to poor sleep quality and negative mental health in youth. Given the public health implications of sleep problems, excessive social media use warrants further investigation to clarify the directionality and strength of their associations with poor sleep quality and negative mental health outcomes.

Associations Among Screen Time, Sleep Duration and Depressive Symptoms Among Chinese Adolescents

OBJECTIVES

Relatively few studies have explored the inter-relationship between screen time (ST), sleep duration and depressive symptoms. The study herein sought to determine (1) the relationships between ST, sleep duration and depressive symptoms among Chinese adolescents; (2) whether sleep duration mediates the relationships between ST and depressive symptoms.

METHODS

1^st grade students (n=1,976) from ten high schools in Guangzhou, China were invited through cluster sampling between January and April 2019. Self-reported ST with electronic devices and Internet, sleep duration, and The Center for Epidemiology Scale for Depression (CES-D) score were collected. Generalized mixed linear models and mediation analyses were conducted.

RESULTS

There were 1,956 self-reported questionnaires received (response rate: 98.99%). Approximately 25% (471/1,929 for Internet use, 399/1,928 for electronic device) of the total sample reported ST >2 hours/day. Approximately 8.9% (169/1,894) reported a CES-D score >28. Longer ST with electronic devices (estimate=0.52, 95%CI: 0.24~0.80), Internet usage (estimate=0.82, 95%CI: 0.53~1.11) were positively associated with depressive symptoms, while less sleep (estimate=-1.85, 95%CI: -2.27~-1.43) was negatively associated with depressive symptoms. There is significant indirect effect of electronic device usage on depressive symptoms through sleep duration (indirect effect=0.08, 95%CI: 0.01~0.15).

LIMITATIONS

This study only included school students from Guangzhou. Causal relationship cannot be inferred by this cross-sectional design.

CONCLUSIONS

ST and sleep duration were significantly associated with depressive symptoms severity. The indirect effect of sleep duration suggests a possible mechanism of the association between ST and depressive symptoms. Future interventions to manage depressive symptoms should target sleep time and decrease ST among adolescents.

A meta-analysis of the relationship between subjective sleep and depressive symptoms in adolescence

BACKGROUND

Adolescence is a risk period for the development of mental illness, as well as a time for pronounced change in sleep behaviour. While prior studies, including several meta-analyses show a relationship between sleep and depressive symptoms, there were many inconsistences found in the literature.

OBJECTIVE

To investigate the relationship between subjective sleep and depressive symptoms.

METHODS

Following PRISMA guidelines, we conducted a literature search that yielded forty-nine recent studies (2014-2020) with adolescent samples aged 9 to 25-year-olds, and more than double the sample size of previous meta-analyses (N = 318,256).

RESULTS

In a series of meta-analyses, we show that while several common categories of subjective sleep are associated with depressive symptoms in adolescents, the strength of this relationship varies. Measures of sleep perception: poor sleep quality (r = 0.41), insomnia (r = 0.37), sleep disturbances (r = 0.36), wake after sleep onset (r = 0.31), and daytime sleepiness (r = 0.30) correlated more strongly with depressive symptoms, than measures of sleep behaviour: sleep latency (r = 0.22), and sleep duration (r = -0.19).

CONCLUSIONS

These findings suggest that in studies of depressive symptoms it may be important to assess an adolescent's perception about their sleep, in addition to their sleep/wake behaviours.

National Trends in Mental Health Care for US Adolescents

Importance

The prevalence of adolescent depression and other internalizing mental health problems has increased in recent years, whereas the prevalence of externalizing behaviors has decreased. The association of these changes with the use of mental health services has not been previously examined.

Objective

To examine national trends in the care of different mental health problems and in different treatment settings among adolescents.

Design, Setting, and Participants

Data for this survey study were drawn from the National Survey on Drug Use and Health, an annual cross-sectional survey of the US general population. This study focused on adolescent participants aged 12 to 17 years interviewed from January 1, 2005, to December 31, 2018. Data were reported as weighted percentages and adjusted odds ratios (aORs) and analyzed from July 20 to December 1, 2019.

Main Outcomes and Measures

Time trends in 12-month prevalence of any mental health treatment or counseling in a wide range of settings were examined overall and for different sociodemographic groups, types of mental health problems (internalizing, externalizing, relationship, and school related), and treatment settings (inpatient mental health, outpatient mental health, general medical, and school counseling). Trends in the number of visits and nights in inpatient settings were also examined.

Results

A total of 47 090 of the 230 070 adolescents across survey years (19.7%) received mental health care. Of these, 57.5% were female; 31.3%, aged 12 to 13 years; 35.8%, aged 14 to 15 years; and 32.9%, aged 16 to 17 years. The overall prevalence of mental health care did not change appreciably over time. However, mental health care increased among girls (from 22.8% in 2005-2006 to 25.4% in 2017-2018; aOR, 1.11; 95% CI, 1.04-1.19; P = .001), non-Hispanic white adolescents (from 20.4% in 2005-2006 to 22.7% in 2017-2018; aOR, 1.08; 95% CI, 1.03-1.14; P = .004), and those with private insurance (from 19.4% in 2005-2006 to 21.2% in 2017-2018; aOR, 1.11; 95% CI, 1.04-1.18; P = .002). Internalizing problems, including suicidal ideation and depressive symptoms, accounted for an increasing proportion of care (from 48.3% in 2005-2006 to 57.8% in 2017-2018; aOR, 1.52; 95% CI, 1.39-1.66; P < .001), whereas externalizing problems (from 31.9% in 2005-2006 to 23.7% in 2017-2018; aOR, 0.67; 95% CI, 0.62-0.73; P < .001) and relationship problems (from 30.4% in 2005-2006 to 26.9% in 2017-2018; aOR, 0.75; 95% CI, 0.69-0.82; P < .001) accounted for decreasing proportions. During this period, use of outpatient mental health services increased from 58.1% in 2005-2006 to 67.3% in 2017-2018 (aOR, 1.47; 95% CI, 1.35-1.59; P < .001), although use of school counseling decreased from 49.1% in 2005-2006 to 45.4% in 2017-2018 (aOR, 0.86; 95% CI, 0.79-0.93; P < .001). Outpatient mental health visits (eg, private mental health clinicians, from 7.2 in 2005-2006 to 9.0 in 2017-2018; incidence rate ratio, 1.30; 95% CI, 1.23-1.37; P < .001) and overnight stays in inpatient mental health settings (from 4.0 nights in 2005-2006 to 5.4 nights in 2017-2018; incidence rate ratio, 1.18; 95% CI, 1.02-1.37; P = .03) increased.

Conclusions and Relevance

This study's findings suggest that the growing number of adolescents who receive care for internalizing mental health problems and the increasing share who receive care in specialty outpatient settings are placing new demands on specialty adolescent mental health treatment resources.

Association between morningness-eveningness, sleep duration, weekend catch-up sleep and depression among Korean high-school students

The present study aimed to examine the association between morningness-eveningness preferences, sleep duration, weekend catch-up sleep duration and depression among Korean high-school students. A total of 8,655 high-school students participated from 15 districts in South Korea and completed an online self-report questionnaire. The following sleep characteristics were assessed: weekday and weekend sleep duration, weekend catch-up sleep duration, morningness-eveningness preference, perceived sufficiency of sleep, self-reported snoring and sleep apnea, daytime sleepiness, and sleep environment. Age, gender, body mass index, number of private classes, proneness to internet addiction, and depressive mood were also evaluated. A logistic regression analysis was conducted to compute odds ratios for the association between depression and sleep characteristics, after controlling for relevant covariates. Eveningness preference was a significant predictor of depressive mood (adjusted OR, 1.71; 95% CI, 1.47-1.99). Weekend CUS durations that were ≥2 hr and enrollment in numerous private classes were associated with a lower risk for depression (0.68, 0.55-0.85; 0.76, 0.60-0.95; respectively). Female gender, underweight and obese body weight, short weekday sleep durations, excessive daytime sleepiness, perceived excessiveness and insufficiency of sleep, self-reported snoring and sleep apnea, proneness to internet addiction and a non-optimal sleep environment were associated with an increased risk for depression. Eveningness preference and insufficient weekday sleep duration were associated with an increased risk for depression. Weekend CUS duration ≥2 hr reduced the risk for depression. Diverse aspects, including sleeping habits and sleep-related environmental factors, should be considered to reduce depressive symptoms in late adolescents.

Anxiety and depression and their relation to the use of electronic devices among secondary school students in Al-Khobar, Saudi Arabia, 2018-2019

BACKGROUND:

Adolescence is a critical transitional period for the development of mental illnesses such as depression or anxiety, and these days, adolescents spend less time playing outside than they do using electronic devices. The aim of this study was to examine the relationship between the use of electronic devices and anxiety and depression in female secondary school students in Al-Khobar City, KSA.

MATERIALS AND METHODS:

This cross-sectional study included 903 female students selected from the four educational districs (Al-Khobar, Al-Thuqbah, Al-Dhahran and Al-Rakah). Data was collected using a self-administered anonymous questionnaire that included questions related sociodemographics and the use of electronic devices, the Beck Depression Inventory, and the Generalized Anxiety Disorder 7-item scale. Data analysis included descriptive statistics frequencies and percentages for categorical variables, and mean and standard deviation for continuous variables. Chi-square test was performed to test for significance for association between categorical variable. Odds ratios were calculated for association of anxiety and depression with various independent variables including the use of electronic devices. A binary logistic regression model was used to determine factors associated with anxiety and depression. All test were performed at 5% significance level.

RESULTS:

The mean age of the participants was 16.29 years (SD=0.84). About 98% reported using electronic devices; 67.3% used electronic devices 2 or more hours daily, and 81.5% used them at bedtime. About 66% students had moderate-to-severe anxiey and 70/5% had mild-to-severe depression. The logistic regression model showed that users of electronic devices at bedtime were 1.524 more likely to have anxiety (P=0.026), while spending more than 2 hours on the devices at bedtime were significantly associated with depression.

CONCLUSION:

The high prevalence of anxiety and depression among female students is worrisome. Finding suggests that adolescents might benefit from a restricted use of electronic devices. It is necessary to develop age-specific guidelines regarding duration of the use of electronic devices and to integrate the development of psychosocial skills into the school curriculum.

Power Point Therapy: An Effective and Simple Treatment for Subacute Back Pain - A Randomized Controlled Trial

OBJECTIVE

Subacute low back pain is a frequent problem with the danger of chronification. Conventional treatment options are not always effective. Power Point therapy (PPT) is a novel approach that uses reflexological insights and can be easily applied by practitioners and patients.

METHODS

Randomized, active controlled study comparing 10 units of PPT of 10 min each, with 10 units of standard physiotherapy of 30 min each. Outcomes were functional scores (Roland Morris Disability, Oswestry, McGill Pain Questionnaire, Linton-Halldén - primary outcome) and health-related quality of life (SF-36), as well as blinded assessments by clinicians (secondary outcome).

RESULTS

Eighty patients consented and were randomized, 41 to PPT, 39 to physiotherapy. Measurements were taken at baseline, after the first and after the last treatment (approximately 5 weeks after enrolment). Multivariate linear models of covariance showed significant effects of time and group (p < 0.001) and for the quality of life variables also a significant interaction of time by group (p < 0.001). Clinician-documented variables showed significant differences at follow-up (p = 0.05 to p < 0.0001).

DISCUSSION

Both physiotherapy and PPT improve subacute low back pain significantly. PPT is likely more effective and should be studied further.

Perceived Benefits and Risks of Social Media: Ethiopian Secondary School Students' Perspectives

Recent findings show teenagers use social media increasingly in their daily life. There is also a consensus that social media have both pros and perils on students’ academic affairs. The objective of this study is to assess how Ethiopian secondary school students perceive the benefits and risks associated with social media use. Data were collected from 353 secondary schools students through self-reported questionnaire. The findings reveal that the leading perceived benefits of social media are recreational and relational purposes. The role social media play in students’ academic activities is likely less considered. As a pilot study in a developing country, this study may raise awareness of schools, teachers, and parents about the benefits and risks of using social media for teenager students. Thereby, there will be future researches that enable them to effectively monitor their students to use social media primarily for academic purposes.

Suicidality in sleep disorders: prevalence, impact, and management strategies

Sleep disturbances are associated with suicide-related thoughts and behaviors, and the incidence of sleep concerns and suicide has increased recently in the US. Most published research exploring the sleep-suicidality relation is focused on select sleep disorders, with few reviews offering a comprehensive overview of the sleep-suicidality literature. This narrative review broadly investigates the growing research literature on sleep disorders and suicidality, noting the prevalence of suicide ideation and nonfatal and fatal suicide attempts, the impact of several sleep disorders on suicide risk, and potential sleep-disorder management strategies for mitigating suicide risk. Aside from insomnia symptoms and nightmares, there exist opportunities to learn more about suicide risk across many sleep conditions, including whether sleep disorders are associated with suicide risk independently of other psychiatric conditions or symptoms. Generally, there is a lack of randomized controlled trials examining the modification of suicide risk via evidence-based sleep interventions for individuals with sleep disorders.

The evaluation of adolescent chest pain: a screening ECG or PSC-17?

PURPOSE OF REVIEW

The present review offers an update on entities presenting as chest pain in the adolescent population. It discusses recently proposed tools and shared mental models used in primary and urgent care settings to evaluate chest pain, and their focus on identifying life-threatening processes. We consider whether the current practice may be improved by accounting for the increasingly recognized non-life-threatening causes of adolescent chest pain.

RECENT FINDINGS

The present experiences and behaviors of adolescents have added new causes of chest pain to the work-up of this disquieting chief complaint. The initial approach to adolescent chest pain has classically focused on ruling out life-threatening entities, and current diagnostic algorithms offer systematic approaches with similar emphases. A growing body of literature on the nonlife-threatening causes of adolescent chest pain, often categorized as idiopathic, suggests a need to reevaluate our practice.

SUMMARY

Adolescent chest pain is most often noncardiac and non-life threatening in nature, yet current diagnostic algorithms and evaluations emphasize identifying the exceptional case of cardiac chest pain. Familiarizing ourselves with the more common causes of chest pain and with our present approach to the evaluation of this particular chief complaint, may help us to better counsel our patients and avoid unnecessary use of valuable resources.

Prevalence of Self-Perceived Snoring and Apnea and Their Association with Daytime Sleepiness in Korean High School Students

Background and Purpose

There has been no nationwide population-based study of the prevalence of self-perceived snoring/apnea in Korean adolescents. The purpose of this study was to estimate prevalence of self-perceived snoring/apnea in Korean high-school students and to evaluate their association with daytime sleepiness.

Methods

An online survey was used to investigate 12,672 students at 75 high schools across the 15 nationwide districts of South Korea. The variables were obtained using a self-reported questionnaire. The students answered questions about self-perceived snoring/apnea during the past 30 days. Daytime sleepiness was measured using a validated Korean version of the Epworth Sleepiness Scale, which was modified for adolescents. Covariates were the sex, school grade, frequency of self-perceived snoring/apnea, body mass index, sleep duration during a school day, and subjective perception of sleep duration.

Results

The prevalence of self-perceived snoring/apnea was 22.8% (26.4% for males vs. 18.8% for females, p<0.001) and 9.2% (10.5% for males vs. 7.7% for females, p<0.001). Obesity was significantly associated with self-perceived snoring [odds ratio (OR)=2.18, 95% confidence interval (CI)=1.94–2.46] and apnea (OR=1.57, 95% CI=1.33–1.86). Multivariate analysis showed that any frequency of self-perceived snoring/apnea was significantly associated with excessive daytime sleepiness (EDS). The OR of EDS increased significantly with the frequency of snoring and apnea. Female, sleep duration of <5 hours during a school day, and subjective perceptions of insufficient and considerable sleep durations were also significantly associated with EDS.

Conclusions

The prevalence of self-perceived snoring/apnea was significantly higher in students who were male and obese. Students with self-perceived snoring/apnea exhibited more significant EDS and an increased risk of EDS as the frequency of snoring and apnea increased.
