Abstract
INTRODUCTION Insomnia is a sleep disorder that particularly affects teenagers. Its psychic and physical consequences are major and make it a public health priority. The main purpose of the study was to provide contemporary data on adolescent sleep and to explore the intrications between insomnia and mood disorders while investigating the chronotype responsibility. METHOD A battery of questionnaires was offered to 1,036 French teenagers, enrolled in secondary school, aged between 12 and 20 years old and living in urban areas for middle school students and in rural areas for high school students. It was mainly composed of the Insomnia Severity Index (ISI), the Hospital Anxiety and Depression Scale (HADS) and the - Morningness-Eveningness Questionnaire (MEQ). The authorities responsible for ethics and professional conduct have issued a favorable opinion. RESULTS This study demonstrated that anxiety, depression, gender and age were factors linked to insomnia, reaffirming a female predisposition and asserting a high school entry effect (especially at 15 years old). The results also indicated that a tendency to vesperality increased the risk and the level of insomnia, thus evoking the responsibility of circadian typologies in this sleep disorder. CONCLUSION This study underlines the importance of prevention and screening for insomnia when entering high school, as well as the need, in sleep disorder clinics and in psychotherapy, to deal with individual circadian rhythms, their consequences and organizational choices in the sleep/wakefulness articulation.

Abstract
INTRODUCTION Despite the growing body of cross-sectional research linking sleep problems and school burnout, hardly any research has investigated the longitudinal relationship between these two constructs. The aim of this study was to examine the bidirectional association between sleep problems and school burnout in middle school students. METHODS A prospective design was used incorporating four time points (approximately 6-month interval). The participants were 1226 (50.3% girls) middle school students from 4 public schools who were in 7th grade at baseline. On average, participants were approximately 12.5 years old at the beginning of the study (Mage = 12.73, SD = 0.68). All participants completed self-report measures in classrooms during regular school hours. The data were analyzed using a cross-lagged structural equation model. We also examined the stability of sleep problems and school burnout in time, and investigated the moderating role of gender. RESULTS The results indicated there is a moderate stability for both sleep problems and school burnout, and those students with sleep problems were more likely to develop school burnout, and vice versa. Gender did not moderate the bidirectional relationship. CONCLUSIONS These results suggest that future studies should investigate whether implementing intervention for sleep problems can decrease the occurrence of school burnout and whether interventions targeting school burnout can improve sleep problems.

Abstract
BACKGROUND Screen media usage has become increasingly commonplace in daily life with children initiating themselves to screen media at an early age. Given the high prevalence of screen viewing among children worldwide, its impact on children's health has become a cause for concern. Unfortunately, little information on the independent association between sleep habits and screen time in French children is currently available. The main aim of this study was to assess possible relationships between screen time and sleep habits (quality, duration, etc.) among young middle school students in France. METHODS A total of 448 (55 % girls) 11-to-12-year-olds from 5 schools were included. Body weight and height were measured according to standard procedures and BMI percentiles were determined based on international reference values. Sleep parameters were obtained by sleep diaries and visual estimations. A sleep diary was maintained for one week to record sleeping and waking times and related information. Information on lifestyle habits (sedentary behaviours, physical activity, and dietary intake) was obtained via standardised questionnaires. RESULTS Participants were 11.5 (±0.4) years of age. From total sample, 25.5 % reported screen time ≥2hours/d during school days and 62.7 % during school-free days. High screen time was associated with significantly poorer sleep habits and these results remained valid after adjustment for several confounding factors (body mass index, sex, center and parental level of educational attainment) (P<0.05). CONCLUSION This study highlights an association between longer screen time and shorter sleep duration in French middle school students aged 11 to 12 years. Preventive measures on use of and exposure to screens are called for. Further studies are necessary to confirm our findings.

Abstract
BACKGROUND Sleep deprivation adversely impacts cognitive performance. A nutritious diet is one strategy that can prevent sleep deprivation and its adverse effects. However, few data exist regarding the influence of diet on sleep duration among adolescents. Hence, it is important to assess whether dietary habits are linked to adequate sleep among adolescents. METHODS The 2013 Youth Risk Behavior Survey data were used in the analysis. Nationally representative samples of adolescents were obtained using a 3-stage cluster design. Selected survey items included number of hours slept on a school night, fruit and vegetable intake, soda and milk intake, breakfast consumption, and demographic variables. Data were analyzed with SAS 9.4 using a logistic regression model. RESULTS Holding other variables constant, an increase in total daily consumption of vegetables, milk, and breakfast increased the odds of sleeping ≥8 hours among participants (p < .01). An increase in daily soda intake decreased the odds of sleeping ≥8 hours among participants (p < .01). Separate logistic models for males and females yielded similar findings (p < .01). CONCLUSIONS Promoting healthy eating habits such as intake of vegetables, milk, and breakfast consumption among adolescents may increase their likelihood of getting adequate sleep.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:E4339. [PMID: 31703294 PMCID: PMC6888280 DOI: 10.3390/ijerph16224339] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Revised: 11/04/2019] [Accepted: 11/05/2019] [Indexed: 11/16/2022]
Abstract
Sleep disturbance and non-medical prescription opioid use (NMPOU) are currently growing public health concerns, and sex differences may result in differential exposure to frequency of NMPOU or sleep disturbance. This study aimed to explore the association between the frequency of lifetime or past-year NMPOU and sleep disturbance and to evaluate whether there was any sex difference in this association among Chinese adolescents. A cross-sectional study was performed in seven randomly selected Chinese provinces through the 2015 School-Based Chinese Adolescents Health Survey. A total of 159,640 adolescents were invited to participate and among them, 148,687 adolescents' questionnaires were completed and qualified for this study (response rate: 93.14%). All analyses were performed for boys and girls separately. There were significant sex differences in the prevalence of lifetime or past-year opioid misuse and sleep disturbance (p < 0.05). Among girls, frequent lifetime NMPOU (adjusted odds ratio [aOR] = 2.09, 95% CI = 1.80-2.44) and past-year NMPOU (aOR = 2.16, 95% CI = 1.68-2.77) were positively associated with sleep disturbance. Among boys, these associations were also statistically significant, while the magnitudes of associations between frequent lifetime NMPOU or past-year NMPOU and sleep disturbance were greater in girls than those in boys. There is a significant sex difference in the prevalence of lifetime or past-year NMPOU and sleep disturbance. Furthermore, exposure to more frequent lifetime or past-year NMPOU is associated with a greater risk of sleep disturbance, especially among girls. Taking into account the sex difference for lifetime or past-year NMPOU may help to decrease the risk of sleep disturbance.

Abstract
Objective/Background: The purpose of the study was to pilot a five-week insomnia treatment in adolescents with major depressive disorder (MDD) and insomnia. This was an open-label trial of a modified-group cognitive behavioral therapy for insomnia (CBTI). Participants: Adolescents with MDD (n = 16; mean age = 17.3 +/- 1.7), characterized by the Children's Depression Rating Scale-Revised T-score ≥ 55 and insomnia, characterized by > 30 min to fall or return to sleep and an Insomnia Severity Index (ISI) score of ≥ 7 participated. Methods: Sleep diaries, actigraphy, weekly ISI, Quick Inventory of Depressive Symptomatology (QIDS), and Multidimensional Fatigue Inventory (MFI) were completed. Results: Paired t-tests comparing pre- and posttreatment revealed a decrease in sleep onset latency from 41 min +/- 14 min to 18 min +/- 8.9 min (t = 5.9, p = .004). Linear mixed modeling across sessions revealed that ISI (B = 11.0, SE = 0.94, p < .001), QIDS (B = 11.3, SE = 0.96, p < .001), and MFI (B = 30.0, SE = 4.4, p < .001) improved across treatment. Daily sleep diaries showed decreased wake during the night (B = 22.8, SE = 7.19, p = .008), increased sleep time (B = 382.4, SE = 71.89, p < .001), and increased quality of sleep (B = 3.7, SE = 0.37, p < .001). When asked whether group members would recommend this group, 27% responded "yes" and 73% responded "definitely yes." Conclusions: Additional controlled studies utilizing sleep-focused therapy in depressed adolescents with insomnia are warranted.

Abstract
OBJECTIVE/BACKGROUND Rates of suicide attempts in Canadian youths are concerning. Adolescence is a sensitive period for the emergence of both sleep and mood problems, two major risk factors for suicidality. This naturalistic study aimed to define the sleep profile of adolescents under the combined influence of suicidality, depression and pharmacotherapy during hospitalization for a suicidal crisis. PATIENTS/METHODS Seventeen suicidal adolescents (15.0 + 1.2years, 82% females) with major depression were recruited from a Canadian pedopsychiatric inpatient unit. Seventeen non-depressed adolescents were retrospectively collated from another database (15.0 + 1.1years, 83% females). None of the participants had a history of sleep disorders or significant medical conditions. RESULTS Compared to controls, suicidal adolescents had a longer sleep onset latency (Z = -4.5, p < 0.001), longer REM latency (Z = -3.2, p = 0.001), higher percentage of NREM1 sleep t(33) = -2.6, p = 0.020), and higher REM density (Z = -2.8, p = 0.004) than controls. Higher REM density correlated with higher CDI-II scores (r = 0.55, p = 0.27) A significant interaction indicated that the two groups had similar NREM3 percentages in the first two-thirds of the night, but that the suicidal group had significantly lower NREM3 percentage than the controls in the last third of the night (F(2,66) = 3.4, p = 0.041). CONCLUSIONS Significant sleep abnormalities were observed during hospitalization for a suicidal crisis in a sample of depressed and mostly medicated adolescents. This included sleep initiation and REM sleep latency abnormalities, shallower sleep and high REM density. Future studies should decipher the relative effects of depression, suicidality and medication on sleep. These findings stress the need to address sleep disturbances in the management of suicidality in adolescents.

Abstract
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.

Abstract
BACKGROUND/AIM While poor sleep quality and sleep problems are signs of depression in adolescents, depressive symptoms among this age group further deteriorate sleep quality. The aim of this study was to explore the relationship between sleep quality and depressive symptoms in adolescents of 14 to 20 years of age. MATERIALS AND METHODS This study was conducted with a descriptive and cross-sectional research design. The sample group consisted of 313 adolescents in İstanbul, Turkey. The data were collected using a questionnaire form, the Beck Depression Inventory (BDI), and the Pittsburgh Sleep Quality Index (PSQI). RESULTS The mean BDI score of the adolescents was 12.99 ± 8.94 (range: 0-53) and 4.8% had severe depressive symptoms. The global PSQI score of the adolescents was 4.69 ± 2.87 (range: 0-16) and 63.6% had good sleep quality, whereas the remaining 36.4% had poor sleep quality. There was a moderate positive correlation between BDI and PSQI scores. The factors affecting the quality of sleep of adolescents were mild and moderate-severe depressive symptom level, smoking, and the presence of sleep problems in a family member. CONCLUSION This study shows a relationship between sleep quality and depressive symptom levels of adolescents. The findings of the current research will contribute to the development of school wellbeing programs that will be prepared with the aim of improving sleep quality and reducing depressive symptoms.

Abstract
Teenage sleeping disorders can have short- and long-term consequences such as learning disorders, accidents, depression, and type 2 diabetes. OBJECTIVE To assess the prevalence of sleeping disorders in high school students in the southwest of Brittany (Finistère), France. To search for family and social factors causing these disorders and drug use. METHOD Observational multicenter study that took place in May, 2015, asking high school students to anonymously complete a questionnaire during school time. A variable was created: sleep disorders (TrS+) when teenagers responded "often" or "very often" to at least one of the six questions concerning sleeping disorders. RESULTS The prevalence of TrS+ was 73 % (4170/5556). These teenagers had difficulty falling asleep (36 %), woke up during the night (33 %), or had nightmares (10 %). Their sleep routine was disrupted (35 %), they did not feel rested the following day (49 %): 9 % were late for class related to their sleeping disorders. TrS+ were more recurrent among females (OR: 2.64; P<0.0001). A negative atmosphere in high school (OR: 2.64; P<0.0001), tobacco use (>10 cigarettes per a day) (OR: 2.39; P<0.0001), alcohol (OR: 1.4, P=0.009), marijuana (<1 time per day; OR: 2.05; P=0.009), and time spent using a computer or watching television (>8h per a day; OR: 2.7; P<0.0001) had an impact on their sleep quality. Ten percent of TrS+ individuals consume medications and 9 % cannabis to help them fall asleep. CONCLUSION Technology, drugs, and well-being at school have an impact on sleep quality. Screening of teenagers with sleeping disorders and information programs for teenagers must be provided by the teaching and medical staff.

Abstract
OBJECTIVE Understanding sleep patterns and related factors is vital to development in adolescence, but there is a dearth of this information among adolescents in developing countries such as Nigeria. Therefore, this study describes the sleep patterns, problems, and predictors of poor sleep quality among schooling adolescents. METHODS In a cross-sectional study design, 450 adolescents were selected and interviewed about their sleep experience and problems over the preceding one-month period using a validated form with components adapted from the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Data were analyzed using descriptive statistics, χ2, and logistic regression model with p set at 0.05. RESULTS The mean age of respondents was 13.4 ± 1.2 years. Only half (50.2%) had a global PSQI score of <6, suggesting little or no difficulty with sleep. Significantly, a higher proportion of respondents spent a short time in bed before sleep, ≤15 min among those who had good sleep quality (81.4%) compared with those who had poor sleep quality (65.2%) (p < 0.001). The odds of having poor sleep quality was significantly higher in the subgroup who had ≤8.5 h sleep than those who had 8.5 h sleep or more (adjusted odds ratio = 4.62; 95% confidence interval = 2.61, 8.17, p < 0.001). CONCLUSION Remarkably poor sleep quality exists among schooling adolescents in Ibadan, Nigeria, and sleep problems are prevalent, especially among those with short sleep duration.

McGlinchey EL, Courtney-Seidler EA, German M, Miller AL. The Role of Sleep Disturbance in Suicidal and Nonsuicidal Self-Injurious Behavior among Adolescents. Suicide Life Threat Behav 2017; 47:103-111. [PMID: 27273654 DOI: 10.1111/sltb.12268] [Citation(s) in RCA: 34] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2015] [Accepted: 01/29/2016] [Indexed: 11/28/2022]
Abstract
The relationship between different sleep disturbances and self-harm thoughts and behaviors was examined among 223 adolescents presenting to a community clinic for mood disorders and suicidal and nonsuicidal self-injurious behaviors. Two-thirds of the adolescents reported nightly, severe sleep complaints. Relative to adolescents without significant sleep complaints, patients with severe sleep complaints at the time of clinic entry endorsed significantly more engagement in nonsuicidal self-injury. Middle insomnia and circadian reversal were both significant predictors of suicide attempts. Terminal insomnia was significantly associated with suicidal ideation. Results support the importance of assessing sleep difficulties among adolescents at risk for suicide.

Abstract
OBJECTIVE The Beck Depression Inventory-II (BDI-II) is one of the most popular scales for evaluating the severity of depression in adolescents as well as adults. The prevalence of depression increases during adolescence, and it has shown a rapid increase with occurrence at an earlier age and a tendency to continue into adulthood. Data from an adolescent nonclinical sample provides us more information related to depressive symptoms as potential risk factors. The current study was designed to two objectives: 1) to analyze the reliability and validity the BDI-II among Korean adolescents and 2) to evaluate the factorial structure in a Korean nonclinical adolescent sample. METHODS The participants included 1072 adolescent boys and girls. We assessed the internal consistency, corrected item-total correlation, and the convergent validity of the BDI-II. We also performed confirmatory factor analyses to determine the internal structure of the BDI-II for Korean adolescents using Mplus 6.1. RESULTS The Cronbach's alpha for the BDI-II total score was 0.89. The correlation between the BDI-II and the PHQ-9 was strong (r=0.75), and anxiety-related measures were 0.68 and 0.71, which were also in the high range. Among the five different factor structures, the modified three-factor model demonstrated the best overall fit. CONCLUSION The BDI-II is a reliable tool for measuring the severity of depressive symptoms in Korean adolescents. Therefore, the findings can provide basic information for examining the prevalence rate, intervention strategies for depression in adolescents.

Abstract
PURPOSE To inform the design of a sleep improvement program for college students, we assessed academic performance, sleep habits, study hours, and extracurricular time, hypothesizing that there would be differences between US-born and foreign-born students. METHODS Questionnaires queried participants on bedtimes, wake times, nap frequency, differences in weekday and weekend sleep habits, study hours, grade point average, time spent at paid employment, and other extracurricular activities. Comparisons were made using chi square tests for categorical data and t tests for continuous data between US-born and foreign-born students. RESULTS Of 120 participants (55 % women) with racial diversity (49 whites, 18 blacks, 26 Hispanics, 14 Asians, and 13 other), 49 (41 %) were foreign-born. Comparisons between US-born and foreign-born students showed no differences in average age or gender though US-born had more whites. There were no differences between US-born and foreign-born students for grade point averages, weekday bedtimes, wake times, or total sleep times. However, US-born students averaged 50 min less study time per day (p = 0.01), had almost 9 h less paid employment per week (14.5 vs 23.4 h per week, p = 0.001), and stayed up to socialize more frequently (63 vs 43 %, p = 0.03). Foreign-born students awakened an hour earlier and averaged 40 min less sleep per night on weekends. CONCLUSIONS Cultural differences among college students have a profound effect on sleep habits, study hours, and extracurricular time. The design of a sleep improvement program targeting a population with diverse cultural backgrounds must factor in such behavioral variations in order to have relevance and impact.

Abstract
OBJECTIVE In this paper, we examined the relationship between insomnia symptoms and suicidality in a national sample of US adolescents, while controlling for several psychiatric disorders that are known to be associated with suicidality. Additionally, we examined whether insomnia symptoms interact to affect any suicidality variables. METHODS Study participants were 10,123 adolescents between the ages of 13-18 from the National Comorbidity Survey - Adolescent Supplement (NCS-A). RESULTS In bivariate analyses, all insomnia symptoms (i.e., difficulty falling asleep, difficulty staying asleep, and early morning awakening) were associated with suicide ideation, plan and attempts. In multivariate analyses, controlling for substance use, mood and anxiety disorders, as well as important covariates, difficulties falling and staying asleep had a significant relationship with 12-month and lifetime suicide variables while early morning awakening did not. CONCLUSIONS Two of the three insomnia symptoms had a significant association with suicide thoughts and plan even after controlling for psychiatric disorders that were known to affect suicidality. Having trouble falling sleeping or staying asleep had both direct and indirect relationships (via substance use, mood and anxiety disorders) on suicidal behavior. Assessment and treatment of sleep disturbances may reduce the risk for suicidality in adolescents.

Abstract
STUDY OBJECTIVES To estimate the prevalence and health correlates of insomnia symptoms and their association with comorbid mental disorders in a nationally representative sample of adolescents in the United States. DESIGN National representative cross-sectional study. SETTING Population-based sample from the US adolescents. MEASUREMENTS AND RESULTS A total of 6,483 individuals aged between 13–18 y in the National Comorbidity Survey-Adolescent Supplement (NCS-A) with both individual and parental reports of mental health were included in this study. Participants were classified with insomnia symptoms if they reported difficulty initiating sleep, difficulty maintaining sleep, and/or early morning awakening, nearly every day for at least 2 w in the past year. Nearly one-third of adolescents reported insomnia symptoms for at least 2 w during the previous year. Hispanic and black youth were significantly more likely to report insomnia symptoms (42.0% and 41.3%, respectively) than non-Hispanic white youth (30.4%). Adolescents with insomnia symptoms were at a higher risk for all classes of mental disorders {odds ratio [OR] (95% confidence interval [CI]: 3.4 (2.9–4.0)} including mood, anxiety, behavioral, substance use, and eating disorders, suicidality [OR (95% CI): 2.63 (1.34–5.16)], poor perceived mental health [OR (95% CI): 2.01 (1.02–3.96)], chronic medical conditions [OR (95% CI): 1.94 (1.55–2.43)], smoking [OR (95% CI: 2.60 (1.00–6.72)], and obesity [OR (95% CI: 1.46 (1.10–1.93)] than those without insomnia symptoms. Adolescents with insomnia symptoms and comorbid mental disorders manifested even greater rates of these indicators of negative health behaviors and disorders than those with mental disorders alone (P < 0.05). CONCLUSIONS Insomnia symptoms are reported by one-third of adolescents in the general population. Insomnia symptoms, even in the absence of concomitant depression or other mental disorders, are associated with serious health conditions, risk factors, and suicidality. Comorbid mental disorders potentiate the effect of insomnia symptoms on both physical and mental health. Further evaluation of the causes and effective interventions to reduce insomnia symptoms may have a significant effect on public health.

Abstract
This study used a case-control design to compare sleep disturbances in 40 adolescents who attempted suicide with 40 never-suicidal adolescents. Using hierarchical logistic regression analyses, we found that self-reported nighttime awakenings were significantly associated with attempted suicide, after controlling for antidepressant use, antipsychotic use, affective problems, and being bullied. In a separate regression analysis, the parent-reported total sleep problems score also predicted suicide attempt status, controlling for key covariates. No associations were found between suicide attempts and other distinct sleep problems, including falling asleep at bedtime, sleeping a lot during the day, trouble waking up in the morning, sleep duration, and parent-reported nightmares. Clinicians should be aware of sleep problems as potential risk factors for suicide attempts for adolescents.

Abstract
We aimed to investigate the effect of sleep problems, depression, and cognitive processes on suicidal risk among 460 young adults. They completed self-report questionnaires assessing suicidal behavior, sleep quality, depressive symptoms, emotion regulation, rumination, and impulsivity. Suicidal participants exhibited higher rates of depressive symptoms, sleep problems, expressive suppression, rumination, and impulsivity. A confirmatory factor analysis model revealed pathways to suicidal risk that showed no direct pathways between sleep problems and suicidal risk. Instead, sleep was related to suicidal risk via depression and rumination, which in turn increased suicidal risk. These results suggest that addressing sleep problems will be useful in either the treatment or prevention of depressive and rumination symptoms and reduction in suicidal risk.

Abstract
Relatively little is known about nightmares and other forms of disturbed dreaming in children. This article reviews the literature on the prevalence and correlates of nightmares in children and highlights key methodological issues in the field. Results show that regardless of how they are defined and measured, nightmares affect a significant proportion of children of all ages and there is some evidence to suggest that nightmare frequency may peak around the age of 10. Gender differences in nightmare frequency, with girls reporting more nightmares than do boys, tend to appear between the ages of 10 and 15. Although nightmares are associated with a range of psychosocial difficulties (e.g., stress, behavioural problems), elevated anxiety and concomitant sleep-related disorders (e.g., sleepwalking) are among the most robust correlates of nightmares. Very few studies have examined nightmare treatment in children, but promising results have been obtained with imagery rehearsal therapy. Overall, research in the field has been hampered by inconsistent definitions for nightmares, by extensive variability in questionnaire items used to measure nightmare frequency, and by a lack of awareness of how using parents versus children as respondents may impact results. Longitudinal studies are needed to better understand how nightmares and their correlates evolve during childhood and adolescence, to delineate their clinical significance, and to develop effective and age-appropriate treatment strategies.

Abstract
STUDY OBJECTIVE To investigate the prevalence and the correlates of sleep disturbance and depressive symptoms among Chinese adolescents and to examine the association between the two problems. DESIGN Cross-sectional survey. PARTICIPANTS A total of 3186 school students in grades 7-12 were sampled from the schools in Guangdong. A stratified-cluster random-sampling strategy was used to select the schools. MAIN OUTCOME MEASURES A self-administered questionnaire was used. The Pittsburgh Sleep Quality index (PSQI) was used to assess the occurrence of sleep disturbance, and the Center for Epidemiology Scale for Depression (CES-D) was used to identify whether individuals had depressive symptoms. RESULTS The mean PSQI global score was 8.7 (±2.4) points, and 39.6% of the total sample had sleep disturbance. The mean CES-D score of students was 15.2 (±9.4) points, and 6.4% of the students had depressive symptoms. Additionally, girls and older adolescents were more likely to suffer from sleep disturbance, and the students who had depressive symptoms were 2.47 (95% CI 1.61 to 3.79) times more likely to suffer from sleep disturbance. Factors that were correlated with sleep disturbance and depressive symptoms were having a poor relationship with teachers, feeling lonely, suicide ideation and having run away from home. CONCLUSIONS Sleep disturbance was determined to be more prevalent among Chinese adolescents with depressive symptoms. Sleep disturbance and depressive symptoms were associated with each other, while school factors, family factors and psychosocial adjustment were comprehensively correlated with both.

Abstract
INTRODUCTION Sleep problems are commonly encountered in adolescents. It has been shown that electronic media have a negative influence on the sleep quality and daytime functioning in adolescents. This study aims to investigate the association between internet use and sleep problems in adolescents. METHOD A total of 1212 adolescents were recruited to the study. Self-report study questionnaire included two main parts: Young's Internet Addiction Scale (IAS) and a semi-structured inquiry on sleep habits/problems. RESULTS Of the study sample, 16% (n=198) reported their sleep quality as bad or very bad. One-fourth of the sample reported using internet everyday and 27% of them reported spending more than one hour when online. The mean IAS total score was 35.56±13.87. Adolescents with a higher IAS score reported getting to bed later in the night, needing more time to fall asleep and having an increased number of awakenings in the night than the adolescents with lower IAS score (p=.001). They were also found to have higher frequencies of several sleep problems including difficulty in initiating and sustaining sleep, difficulty in waking up and feelings of sleepiness in day. In addition, sleep quality of them was worse when compared to the adolescents with a lower IAS score (p=.001). CONCLUSION Problematic sleep habits and sleep problems were found to be more frequent in adolescents with a higher IAS total score. Health care providers must be aware of the possible negative impact of excessive and uncontrolled internet use on adolescents' sleep habits.

Abstract
BACKGROUND This study examines the relationships between circadian preference and caffeine use with academic performance and hours spent studying for recent high school graduates entering their first year of college. METHOD Entering first-year college students enrolled at 90 baccalaureate-level institutions across the USA were invited to complete the Beginning College Survey of Student Engagement (BCSSE) and the Composite Scale of Morningness (CSM) as well as answer questions regarding caffeine consumption. Surveys were administered on each campus during the summer months of 2013. Only those that graduated from a US high school in the spring of 2013 were included in this study. The final sample for this study included 25,200 students that completed the BCSSE, CSM, and questions regarding caffeine consumption. RESULTS Evening types (E-types) were significantly less likely to report earning A/A-'s in high school and less likely to study 16 or more hours per week compared to intermediate or morning types (M-types) (p < 0.05). Overall, entering first-year students reported an average of 1.1 servings of caffeine per day, with 39 % reporting no caffeine consumption. M-types were more likely to consume no caffeine (54 %) compared to E-types that also indicated no daily caffeine (31 %) (p < 0.05). However, E-types were approximately 2.5 times more likely to consume three or more daily servings of caffeine (18 %) compared to M-types that consume the same amount (7 %) (p < 0.05). M-types that consumed no caffeine reported the highest grades with nearly 64 % reporting they earned mostly A's or A-'s in high school. However, the apparent advantage that morning types had over evening types regarding high school grades was completely ameliorated once three or more servings of caffeine were consumed per day. CONCLUSIONS This study provides additional information to educators and health professionals to create programs and provide resource to help adolescents better understand the impact of their sleep behaviors and use of caffeine on their academic performance.

Abstract
Significant association between sleep disturbances and suicidal ideation and/or attempts is reported in adults and adolescents. However, there is paucity of studies exploring the association between sleep and self-harm behaviors (SHB) in young children and are limited to only subjective sleep measures. We examined the association between SHB and both subjective and objective sleep in a population-based sample of 5-12 yr old. Parents of every student in 3 local school (K-5) districts (n=7312) was sent a screening questionnaire. Randomly selected children from this sample underwent a comprehensive history, physical examination, a 9-h overnight polysomnogram and completed several questionnaires. Among the final sample (n=693), 27 children had SHB with adjusted prevalence of 3%. There was no difference in age, gender, obesity, or socioeconomic status in subjects with or without SHB. Significantly more children with SHB had subjective sleep difficulty and depression. Difficulty maintaining sleep and frequent nightmares were associated with SHB independent of depression or demographics. Polysomnographic %REM-sleep was significantly higher in the SHB group after adjusting for demographics and depression. These data indicate that parent reported sleep disturbances are independently associated with SHB. It is possible that higher REM-sleep is a non-invasive biomarker for risk of self-harm behaviors in young children.

Abstract
STUDY BACKGROUND Mental health and sleep problems are important public health concerns among adolescents yet little is known about the relationship between sleep, depressive symptoms, and suicidality among American Indian youth. METHODS This study examined the impact of sleep and other factors on depressive symptoms and suicidality among Lumbee American Indian adolescents (N=80) ages 11-18. RESULTS At the bivariate level, sleepiness, was associated with depression but not with suicidality. Time in bed (TIB) was not associated with depression, but more TIB decreased the likelihood of suicidality. Higher levels of depressive symptoms were associated with increased likelihood of suicidality. At the multivariate level, sleepiness, suicidality, and self-esteem were associated with depression. TIB and depressive symptoms were the only variables associated with suicidality. CONCLUSION In working with American Indian youth, it may be helpful to consider sleep patterns as part of a comprehensive assessment process for youth who have or are at risk for depression and suicide.

Abstract
STUDY OBJECTIVE To test whether sleep duration on school nights differs between adolescents in Australia and the United States and, if so, whether this difference is explained by cultural differences in school start time, parental involvement in setting bedtimes, and extracurricular commitments. PARTICIPANTS Three hundred eighty-five adolescents aged 13 to 18 years (M = 15.57, SD = 0.95; 60% male) from Australia and 302 adolescents aged 13 to 19 years (M = 16.03, SD = 1.19; 35% male) from the United States. METHODS Adolescents completed the School Sleep Habits Survey during class time, followed by an 8-day sleep diary. RESULTS After controlling for age and gender, Australian adolescents obtained an average of 47 minutes more sleep per school night than those in the United States. Australian adolescents were more likely to have a parent-set bedtime (17.5% vs. 6.8%), have a later school start time (8:32 a.m. vs. 7:45 a.m.), and spend less time per day on extracurricular commitments (1 h 37 min vs. 2 h 41 min) than their U.S. peers. The mediating factors of parent-set bedtimes, later school start times, and less time spent on extracurricular activities were significantly associated with more total sleep. CONCLUSIONS In addition to biological factors, extrinsic cultural factors significantly affect adolescent sleep. The present study highlights the importance of a cross-cultural, ecological approach and the impact of early school start times, lack of parental limit setting around bedtimes, and extracurricular load in limiting adolescent sleep.

Abstract
OBJECTIVE Previous research has found a longitudinal relationship between sleep problems and suicidal behavior while controlling for depression and other important covariates in a high risk sample of adolescents and controls. In this paper, we replicated this longitudinal relationship in a national sample and examined whether the relationship was partially mediated by depression, alcohol-related problems and other drug use. METHODS Study participants were 6504 adolescents from the National Longitudinal Study of Adolescent Health (ADD HEALTH). RESULTS In bivariate analyses, sleep problems (i.e., having trouble falling asleep or staying asleep) at Wave 1 were associated with suicidal thoughts and suicide attempts at Waves 1, 2, and 3 (W1, 2 and 3). In multivariate analyses, controlling for depression, alcohol problems, illicit drug use, and important covariates such as gender, age, and chronic health problems, sleep problems at a previous wave predicted suicidal thoughts and suicide attempts at a subsequent wave. In mediation analyses, W2 depression significantly mediated the effect of W1 sleep problems on W3 suicide thoughts. Moreover, W2 suicidal thoughts also significantly mediated the effect of W1 sleep problems on W3 suicidal attempts. CONCLUSIONS Sleep problems appear to be a robust predictor of subsequent suicidal thoughts and attempts in adolescence and young adulthood. Having trouble falling sleeping or staying asleep had both direct and indirect effects (via depression and suicidal thoughts) on suicidal behavior. Future research could determine if early intervention with sleep disturbances reduces the risk for suicidality in adolescents and young adults.

Abstract
BACKGROUND Sleep is usually considered as a factor for good health and personal equilibrium. However, the epidemiology of insomnia, which is the most frequent of sleep disorders, is still unknown in France. METHODS All epidemiological studies concerning the prevalence of insomnia and its associated factors carried out in France and published between 1980 and 2009 have been extracted from Medline. Subsequently, a research of reports not indexed in Medline has been carried out in the national Public health Database. We also sought the presence of questions concerning sleep disorders in questionnaires and reports from health surveys in the general population. RESULTS In the general population, six specific studies had been undertaken between 1987 and 2003 while there had been eight occupational studies between 1980 and 2000. Surveys in schoolchildren and in students focused on the daytime tiredness due to lack of sleep but few studies investigated insomnia in children and teenagers. Methodological differences as well as the heterogeneity in the definition of the disorders yielded very diverse prevalences. Between 30 and 50% of adults in France declared the presence of at least one sleep disorder while the prevalence of insomnia using the DSM-IV criteria concerned between 15 and 20% of the population. Women reported sleep disorders more frequently than men. Sleep disorders were associated with work absenteeism. Comorbidity with anxiety and depressive disorders has also been highlighted in several studies. CONCLUSION Surveillance of sleep disorders appears as an important public health issue requiring prior standardization of questionnaires and survey methods.

Abstract
If the factors affecting the mental health status of adolescents and their association with sleep status could be clarified, this information would be helpful for formulating lifestyle and healthcare guidance for the promotion of healthy growth and the prevention of mental problems in these individuals. The purpose of this study was to clarify (1) the factor structure of the 12-item General Health Questionnaire (GHQ-12), and (2) the associations between the factors extracted from this questionnaire and lifestyle, in particular sleep status, by using a representative sample population of Japanese adolescents. One hundred three thousand sixty hundred fifty self-administered questionnaires were collected from students enrolled in junior high and high schools in Japan. Of these questionnaires, 99,668 were analyzed. Sleep duration, subjective sleep assessment, bedtime, and insomnia symptoms of these students over the past month were studied to investigate sleep status. The factor analyses yielded two factors: depression/anxiety and loss of positive emotion. Sleep duration of less than 7h was found to be associated with both depression/anxiety and loss of positive emotion, whereas sleep duration of 8h or more was associated only with loss of positive emotion. Subjective sleep assessment and insomnia symptoms were associated with both depression/anxiety and loss of positive emotion. It was demonstrated that two underlying factors of mental health status were associated with differences in sleep status. In order to improve the mental health status of adolescents, it is important to provide guidance about sleep and lifestyle habits according to the mental health status of the individual.

Abstract
OBJECTIVE Previous research has found an association between sleep problems and suicidal behavior. However, it is still unclear whether the association can be largely explained by depression. In this study, we prospectively examined relationships between sleep problems when participants were 12-14 years old and subsequent suicidal thoughts and self-harm behaviors--including suicide attempts--at ages 15-17 while controlling for depressive symptoms at baseline. METHODS Study participants were 280 boys and 112 girls from a community sample of high-risk alcoholic families and controls in an ongoing longitudinal study. RESULTS Controlling for gender, parental alcoholism and parental suicidal thoughts, and prior suicidal thoughts or self-harm behaviors when participants were 12-14 years old, having trouble sleeping at 12-14 significantly predicted suicidal thoughts and self-harm behaviors at ages 15-17. Depressive symptoms, nightmares, aggressive behavior, and substance-related problems at ages 12-14 were not significant predictors when other variables were in the model. CONCLUSIONS Having trouble sleeping was a strong predictor of subsequent suicidal thoughts and self-harm behaviors in adolescence. Sleep problems may be an early and important marker for suicidal behavior in adolescence. Parents and primary care physicians are encouraged to be vigilant and screen for sleep problems in young adolescents. Future research should determine if early intervention with sleep disturbances reduces the risk for suicidality in adolescents.

Abstract
OBJECTIVE Insomnia has been linked to suicidal ideas and suicide death in cross-sectional and longitudinal population-based studies. A link between insomnia and suicide has not been previously examined in the setting of a clinical trial. Herein we describe the relationship between insomnia and suicidal thinking during the course of a clinical trial for depression with insomnia. METHODS Sixty patients aged 41.5±12.5 years (2/3 women) with major depressive episode and symptoms of insomnia received open-label fluoxetine for 9 weeks and also received blinded, randomized eszopiclone 3mg or placebo at bedtime after the first week of fluoxetine. Insomnia symptoms were assessed with the Insomnia Severity Index (ISI), and suicidal ideation was assessed with The Scale for Suicide Ideation (SSI). Depression symptoms were assessed with the depressed mood item and the anhedonia item from the Hamilton Rating Scale for Depression-24 (HRSD24), as well as a sum score for all non-sleep and non-suicide items from the HRSD (HRSD20). Measurements were taken at baseline and weeks 1, 2, 4, 6, and 8. SSI was examined by generalized linear mixed models for repeated measures as the outcome of interest for all 60 participants with ISI and various mood symptoms as independent variables, with adjustment for age, gender, treatment assignment, and baseline SSI. RESULTS Higher levels of insomnia corresponded to significantly greater intensity of suicidal thinking (p<0.01). The depressed mood item of the HRSD, and the sum of the HRSD20, both corresponded to greater suicidal thinking (p<0.001). The anhedonia item did not correspond with suicidal thinking. When both ISI and the depressed mood item, or ISI and the anhedonia item, were included together in the same model, the ISI remained an independent predictor of suicidal thinking. CONCLUSIONS The results support the concept that insomnia may be a useful indicator for suicidal ideation and now extend this idea into clinical trials. Insomnia remains an independent indicator of suicidal ideation, even taking into account the core symptoms of depression such as depressed mood and anhedonia. The complaint of insomnia during a depression clinical trial might indicate that more direct questioning about suicide is warranted.

A longitudinal study among adolescents. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2009; 19:641-9.

Abstract
The quantity and quality of adolescents' sleep may have changed due to new technologies. At the same time, the prevalence of neck, shoulder and low back pain has increased. However, only a few studies have investigated insufficient quantity and quality of sleep as possible risk factors for musculoskeletal pain among adolescents. The aim of the study was to assess whether insufficient quantity and quality of sleep are risk factors for neck (NP), shoulder (SP) and low back pain (LBP). A 2-year follow-up survey among adolescents aged 15-19 years was (2001-2003) carried out in a subcohort of the Northern Finland Birth Cohort 1986 (n = 1,773). The outcome measures were 6-month period prevalences of NP, SP and LBP. The quantity and quality of sleep were categorized into sufficient, intermediate or insufficient, based on average hours spent sleeping, and whether or not the subject suffered from nightmares, tiredness and sleeping problems. The odds ratios (OR) and 95% confidence intervals (CI) for having musculoskeletal pain were obtained through logistic regression analysis, adjusted for previously suggested risk factors and finally adjusted for specific pain status at 16 years. The 6-month period prevalences of neck, shoulder and low back pain were higher at the age of 18 than at 16 years. Insufficient quantity or quality of sleep at 16 years predicted NP in both girls (OR 4.4; CI 2.2-9.0) and boys (2.2; 1.2-4.1). Similarly, insufficient sleep at 16 years predicted LBP in both girls (2.9; 1.7-5.2) and boys (2.4; 1.3-4.5), but SP only in girls (2.3; 1.2-4.4). After adjustment for pain status, insufficient sleep at 16 years predicted significantly only NP (3.2; 1.5-6.7) and LBP (2.4; 1.3-4.3) in girls. Insufficient sleep quantity or quality was an independent risk factor for NP and LBP among girls. Future studies should test whether interventions aimed at improving sleep characteristics are effective in the prevention and treatment of musculoskeletal pain.

Abstract
Sleep problems are an essential part of the current diagnostic criteria for depressive and bipolar disorders in children and adolescents. Whereas many studies have reported subjective sleep problems in youth with depression or bipolar disorder, except for reduced rapid eye movement latency associated with depression, few objective mood-related sleep abnormalities have been consistently identified. Recent technologic advances, such as spectral EEG and actigraphy, hold promise for revealing additional objective disturbances. There are presently few evidence-based published practice recommendations for mood-related sleep problems in youth. In this article, the authors chronologically review research on the phenomenology and treatment of sleep difficulties in youth with depressive and bipolar disorders and present research-based and clinically guided recommendations for the assessment and treatment of these problems.

Abstract
BACKGROUND A limited number of longitudinal studies have addressed the association between sleep disturbance and mental health status among adolescents. To examine whether each of these is a risk factor for the onset of the other, we conducted a prospective longitudinal study of Japanese adolescents. METHODS In 2004, we performed a baseline study of students attending three private junior high schools in Tokyo, and in 2006, a follow-up study was performed on the same population. The mean age of the subjects was 13 years. The Pittsburgh Sleep Quality Index was used to evaluate sleep disturbance, and the 12-item General Health Questionnaire was used to evaluate mental health status. RESULTS The subjects were 698 students, of whom 516 were suitable for analysis. The incidence of newly developed poor mental health status during the 2 years leading to the follow-up study was 35.1%. New onset of poor mental health status was significantly associated with new onset of sleep disturbance and lasting sleep disturbance. The incidence of sleep disturbance during the 2 years leading to the follow-up study was 33.3%. New onset of sleep disturbance was significantly associated with new onset of poor mental health status and lasting poor mental health status. CONCLUSIONS Sleep disturbance and poor mental health status increase each other's onset risk.

Abstract
We examined sleep difficulties preceding death in a sample of adolescent suicide completers as compared with a matched sample of community control adolescents. Sleep disturbances were assessed in 140 adolescent suicide victims with a psychological autopsy protocol and in 131 controls with a similar semistructured psychiatric interview. Rates of sleep disturbances were compared between groups. Findings indicate suicide completers had higher rates of overall sleep disturbance, insomnia, and hypersomnia as compared with controls within both the last week and the current affective episode. Group differences in overall sleep disturbance (both within the last week and present episode), insomnia (last week), and hypersomnia (last week) remained significant after controlling for the differential rate of affective disorder between groups. Similarly, overall sleep disturbance (last week and present episode) and insomnia (last week) distinguished completers in analyses accounting for severity of depressive symptoms. Only a small percentage of the sample exhibited changes in sleep symptom severity in the week preceding completed suicide, but of these, a higher proportion were completers. These findings support a significant and temporal relationship between sleep problems and completed suicide in adolescents. Sleep difficulties should therefore be carefully considered in prevention and intervention efforts for adolescents at risk for suicide.
