Associations between multiple sleep dimensions and suicide and non-suicidal self-injury: a cross-sectional study of 3828 Chinese young people. Soc Psychiatry Psychiatr Epidemiol 2024:10.1007/s00127-024-02689-z. [PMID: 38780778 DOI: 10.1007/s00127-024-02689-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 05/17/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE Suicide and non-suicidal self-injury (NSSI) are preventable concerns in young people. Suicidal ideation (SI), suicidal plans (SP) and suicidal attempt (SA) are closely related to death. Sleep problems are known risk factors for suicide and NSSI. This study aimed to explore the relationship between sleep, suicidality and NSSI. METHODS Participants were 3,828 middle school and college students aged 11-23 years from urban and rural areas of Henan Province. Sleep, suicidal phenomena and NSSI were assessed by applying self-reported questionnaires. Chi-squared tests were utilized to demonstrate the demographic data and sleep variables. The correlation between sleep, suicidality and NSSI were explored by using binary logistic regression, while adjusting socio-demographic characteristics with multivariate models. RESULTS Sleep variables except mid-sleep time were related to suicidal phenomena (P < 0.05). Greater social jet lag (SJL) [≥ 2 h (h)] was associated with increased risk of SI [Odds ratios (OR) = 1.72, 95% confidence intervals (CI):1.40-2.11], SP (OR = 2.10, 95%CI:1.59-2.79) and SA (OR = 1.50, 95%CI:1.00-2.26). Non-only child participants with SJL (≥ 2 h) had significantly increased odds of SI (OR = 1.75, 95%CI: 1.41-2.18) and SP (OR = 2.25, 95%CI: 1.66-3.05). Eveningness chronotype had the strongest correlation with SI (OR = 3.87, 95%CI:2.78-5.38), SP (OR = 4.72, 95%CI:2.97-7.50), SA (OR = 6.69, 95%CI:3.08-14.52) and NSSI (OR = 1.39, 95%CI:1.02-1.90). CONCLUSION Overlong or short sleep duration, SJL, eveningness chronotype and other sleep abnormalities (e.g., daytime dysfunction, low sleep efficiency) were associated with a higher prevalence of SI, SP and SA. Additionally, eveningness was significantly correlated with NSSI among young people. These findings suggested the importance of assessing and intervening in sleep habits to prevent suicide and NSSI in young people.

Abstract
PURPOSE This longitudinal data analysis examined the bidirectional relationships between sleep problems and suicidal thought (ST)/attempt (SA) in a large sample of Chinese adolescents. METHODS A total of 6995 adolescents (mean age = 14.86 years and 51.4% males) participated in a 3-wave longitudinal study of behavior and health in Shandong, China. A self-administered questionnaire and standardized scales were used to assess ST, SA, sleep duration, insomnia, daytime sleepiness, and behavioral/emotional problems in 2015 (T1), 1 year later (T2), and 2 years later (T3). Path analyses were performed without and with adjustment for covariates, including gender, grade level, chronic diseases, cigarette smoking, alcohol use, anxiety/depressive symptoms, paternal education, and family economic status. RESULTS The prevalence rates of short sleep (<7 h/night), insomnia symptoms, and daytime sleepiness were 46.9-58.8%, 16.0-19.4%, and 25.1-25.3% at T1, T2, and T3, respectively. The rates of past-year ST and SA were 9.1-12.4% and 1.6-2.4% at T1, T2, and T3, respectively. Path analyses showed that short sleep, insomnia, and daytime sleepiness predicted subsequent ST, and vice versa. Daytime sleepiness and SA predicted each other 1 year later. Sleep problems and ST/SA in the previous year significantly predicted themselves in the follow-up year. STUDY LIMITATION All data were based on self-report. CONCLUSION Short sleep, insomnia, and daytime sleepiness all had bidirectional relationships with ST. Daytime sleepiness and SA were bidirectionally linked. Our findings suggest that interventions should be taken for both night sleep disturbances and daytime sleepiness to prevent suicide. Adverse sleep outcomes in suicidal adolescents should be assessed, which can in turn increase suicide risk.

Abstract
OBJECTIVES This cross-sectional study aimed to examine the relationships of sleep timing and sleep variability with depressive symptoms, health-related quality of life (HRQoL), daytime sleepiness, and body mass index (BMI) in adolescents. METHODS Adolescents from three schools (n = 571, 56% female, 16.3 ± 1.0 years) had their sleep examined by actigraphy, their anthropometrics assessed, and answered a survey. Sleep timing was examined by combining groups of median-dichotomized onset and wakeup times (early onset and early wakeup; early onset and late wakeup; later onset and early wakeup; later onset and later wakeup); sleep variability was based on within-participant standard deviations of onset and wakeup; and sleep duration as the length of time between onset and wakeup. The sleep variables were separated for weekdays and weekend. Mixed linear models were fitted to compare each sleep variable with health-related outcomes. RESULTS Higher values of daytime sleepiness were observed in adolescents from the late-early and late-late timing group during the week. Greater sleep midpoint and wakeup variability on weekdays were related with higher daytime sleepiness. Adolescents in the late-late and early-late groups showed higher daytime sleepiness. Increased of all sleep variability variables was related with greater daytime sleepiness. Higher depressive symptoms scores were found among adolescents in the late-early subgroup and with the increase of sleep variability. Participants with greater sleep onset variability and sleep midpoint variability reported less HRQoL. CONCLUSIONS Not only sleep duration, but sleep timing and variability also relate to health outcomes, and should be addressed by policies and interventions among adolescents.

Abstract
BACKGROUND Longitudinal data on the associations between sleep disturbances, daytime sleepiness, and daily functioning are limited in the general adolescent population. This study examined the cross-sectional and longitudinal associations between insomnia, excessive daytime sleepiness (EDS), and subject-specific academic performance in a large sample of Chinese adolescents. METHOD Data were derived from the Shandong Adolescent Behavior and Health Cohort (n = 7,072) study. A self-administered questionnaire was used to assess insomnia, EDS, academic performance (overall, Chinese, mathematics, and English), behavioral and emotional problems, and family demographics. The cross-sectional analysis was conducted with baseline data while the longitudinal analysis was conducted with both baseline and 1-year follow-up data. Logistic regression analyses and mediation models were performed to examine the associations between insomnia, EDS, and academic performance. RESULTS Logistic regression analyses revealed that insomnia and EDS had significant cross-sectional associations with overall performance and mathematics performance after controlling for age, gender, ever smoking, ever alcohol drinking, frequent snore, sleep duration, chronic disease, anxious/depressive symptoms, parents' education, parents' occupation, and family economic status. Both insomnia (OR = 1.20, 95% CI: 1.00-1.45) and EDS (OR = 1.22, 95% CI: 1.03-1.45) at baseline were significantly associated with poor mathematics performance 1 year later. The effect of insomnia at baseline on poor academic performance 1 year later was mediated by EDS except for the Chinese subject after controlling for the covariates. CONCLUSIONS Insomnia and daytime sleepiness are significantly associated with poor academic performance, particularly in mathematics. EDS mediates the association between insomnia and poor academic performance. Further research is warranted to investigate the effects of sleep disturbance and daytime sleepiness on the learning process and performance across academic subjects.

Abstract
BACKGROUND The aim of the present study was to analyze the association between course type and health among high school students. METHODS A cross-sectional study with 675 Brazilian high school students. The independent variable was course type (general or vocational) and dependent variables were health characteristics. All information was obtained by a self-report questionnaire and the following health characteristics were analyzed: mental health, physical activity, sedentary behavior, food consumption, daytime sleepiness, tobacco use, alcohol consumption, aggression, and musculoskeletal symptoms. The prevalence ratio (PR) was estimated by Poisson regression. RESULTS Vocational students presented a higher prevalence in 7 of the 20 mental health symptoms analyzed (PR = 1.21-1.64), daytime sleepiness (PR = 1.39-1.71), and musculoskeletal symptoms in neck, shoulders, low back, and knees (PR = 1.31-1.41), and a lower likelihood of being physically active (PR = 0.59-0.70). Conversely, vocational students showed lower sedentary behavior on TV and videogames during the week (PR = 0.35-0.46), consumption of snacks, cookies, and crackers (PR = 0.56-0.72), and experiences of aggression (PR = 0.13-0.17), all P < .05. CONCLUSIONS High school can affect students' health distinctly, indicating that intervention programs and health monitoring should be specific to course type.

JOURNAL OF SPORT AND HEALTH SCIENCE 2022; 11:252-259.

Abstract
BACKGROUND Physical activity, sleep, and sedentary behaviors compose 24-h movement behaviors and have been independently associated with depressive symptoms. However, it is not clear whether it is the movement behavior itself or other contextual factors that are related to depressive symptoms. The objective of the present study was to examine the associations between self-reported and accelerometer-measured movement behaviors and depressive symptoms in adolescents. METHODS Cross-sectional data from 610 adolescents (14-18 years old) were used. Adolescents answered questions from the Center for Epidemiological Studies Depression scale and reported time spent watching videos, playing videogames, using social media, time spent in various physical activities, and daytime sleepiness. Wrist-worn accelerometers were used to measure sleep duration, sleep efficiency, sedentary time, and physical activity. Mixed-effects logistic regressions were used. RESULTS Almost half of the adolescents (48%) were classified as being at high risk for depression (score ≥20). No significant associations were found between depressive symptoms and accelerometer-measured movement behaviors, self-reported non-sport physical activity, watching videos, and playing videogames. However, higher levels of self-reported total physical activity (odd ratio (OR) = 0.92, 95% confidence interval (95%CI): 0.86-0.98) and volume of sports (OR = 0.88, 95%CI: 0.79-0.97), in minutes, were associated with a lower risk of depression, while using social media for either 2.0-3.9 h/day (OR = 1.77, 95%CI: 1.58-2.70) or >3.9 h/day (OR = 1.67, 95%CI: 1.10-2.54), as well as higher levels of daytime sleepiness (OR = 1.17, 95%CI: 1.12-1.22), were associated with a higher risk of depression. CONCLUSION What adolescents do when they are active or sedentary may be more important than the time spent in the movement behaviors because it relates to depressive symptoms. Targeting daytime sleepiness, promoting sports, and limiting social media use may benefit adolescents.

Abstract
Given the limited data currently available in the literature, the aim of this study was to investigate the risk of excessive daytime sleepiness (EDS) associated with major depression in a large sample of adolescents. The clinical and polysomnographic data of 105 adolescents recruited from the database of the Erasme Hospital sleep laboratory were analysed. A score > 10 on the Epworth Sleepiness Scale was used as cut-off for the diagnosis of EDS. The status (remitted or current) and the severity (mild to moderate or severe) of major depressive episodes were determined based on the diagnostic criteria of the DSM-IV-TR during a systematic psychiatric assessment. Logistic regression analyses were performed to determine the risk of EDS associated with major depression in adolescents. The prevalence of EDS was 34.3% in our sample of adolescents. After adjusting for the main confounding factors associated with EDS, multivariate logistic regression analysis demonstrated that unlike mild to moderate major depression, remitted major depression and severe major depression were risk factors for EDS in adolescents. In our study, we have highlighted that in adolescents, the EDS could be both residual symptom and severity marker of major depression, which seems to justify a systematic psychiatric assessment in adolescents with EDS complaints in order to allow better management of this problem in this particular subpopulation.

Abstract
Background Interoception is mental awareness, recognition and acknowledgement of physiological body signals. Understanding the role of sleep and interoception may provide a better understanding surrounding the sleep-health connection. Our primary objective was to examine the potential relationships between subjective sleep quality and multiple dimensions of interoceptive abilities in a large sample of young adults, a group who are vulnerable to sleep impairment and its widespread health consequences. Methods We conducted an online cross-sectional survey targeting young adults, aged 18–25 years. The Pittsburgh Sleep Quality Index (PSQI) was used to identify subjective sleep quality and the Multidimensional Assessment of Interoceptive Awareness Version 2 was used to assess eight domains of interoception. We conducted a series of Spearman’s bivariate correlations to assess the relationships between global sleep quality as well as the seven PSQI sub-components in relation to the eight interoception outcomes. We then conducted quantile regression to assess if global PSQI score was an independent predictor of interoception. Participants (n = 609) consented and provided data. Results After adjustment, the global PSQI was a significant predictor of ‘Non-Distracting’, ‘Emotional Awareness’ and ‘Trusting’, where β = − 0.10 (95% CI: − 0.14, − 0.07), β = 0.05 (0.01, 0.09), and β = − 0.10 (− 0.14, − 0.05), respectively. Conclusions Our findings reveal a small, significant relationship between sleep quality and interoceptive abilities amongst young adults. Sleep impairment may inhibit interoceptive skills, thus adding value to the mechanistic explanation of the sleep-health relationship. Experimental and prospective studies are needed to determine temporal associations.

Abstract
The study aimed to investigate the relationships between current exclusive e-cigarette use, exclusive combustible cigarette smoking, and dual use of e-cigarettes and combustible cigarettes, and insufficient sleep among U.S. adolescents. We conducted a secondary data analysis of the 2017 Youth Risk Behavior Survey including 11,296 U.S. high school students. Current (past 30-day) tobacco use groups included exclusive e-cigarette users, exclusive combustible cigarette smokers, and dual-product users. We performed weighted unadjusted and adjusted logistic regression analyses. Insufficient sleep was defined as <8 h/night and < 7 h/night. Overall, 73.4% of adolescents reported insufficient sleep <8 h/night. Compared with non-tobacco users, exclusive e-cigarette users were more likely to report insufficient sleep <8 h/night (odds ratio [OR] = 1.55, 95%CI = 1.12-2.14; adjusted OR [aOR] = 1.57, 95%CI = 1.01-2.43) and < 7 h/night (OR = 1.55, 95%CI = 1.19-2.01; aOR = 1.61, 95%CI = 1.16-2.24). Dual-product users were at increased odds to report insufficient sleep <8 h/night (OR = 3.15, 95%CI = 1.87-5.32) and < 7 h/night (OR = 2.64, 95%CI = 1.87-3.72; aOR = 1.73, 95%CI = 1.14-2.62) than non-tobacco users. Exclusive combustible cigarette smokers were less likely to report insufficient sleep <8 h/night (aOR = 0.49, 95%CI = 0.29-0.84) than non-tobacco users, but no differences were found based on insufficient sleep <7 h/night. When comparing current use groups, exclusive e-cigarette users were at 3.20 increased odds (95%CI = 1.65-6.22) and dual-product users were at 3.26 increased odds (95%CI = 1.51-7.03) to report insufficient sleep <8 h/night when compared with exclusive combustible cigarette smokers after covariate adjustment. Dual-product users were 1.89 times more likely (95%CI = 1.01-3.51) to report insufficient sleep <7 h/night when compared with exclusive combustible cigarette smokers. School-based prevention efforts for tobacco use may promote sufficient sleep in youth.

Abstract
Objectives To compare sedentary behaviour and physical activity between short sleepers and adequate sleepers in a sample of Brazilian adolescents. Material and Methods 688 adolescents wore accelerometers on the non-dominant wrist for seven days. Sleep duration, sedentary behaviour, light (LPA), moderate (MPA), and vigorous physical activity (VPA) were estimated. Participants were classified as short (<8h/night) or adequate sleepers (≥8h/night). The minutes and the percentage of time spent in each waking behaviour was compared between short and adequate sleepers. Results Participants were 16.3 years old, 50.4% were female, and 67.7% were short sleepers. Adequate sleepers engaged in less (min/day) sedentary behaviour (-53.46), LPA (-25.44), MPA (-4.27), and VPA (-0.63) compared to short sleepers. However, no differences were observed for the proportion of time (68% in sedentary behaviour, 28% in LPA, 3% in MPA, and <0.4% in VPA). Conclusion Patterns of waking behaviours are similar between short and adequate sleepers.

Abstract
OBJECTIVES American Indian/Alaska Native (AI/AN) youth are a high-risk group for sleep problems and associated chronic conditions. Urban AI/AN youth may face certain challenges, including specific psychosocial stressors (e.g., discrimination) and environmental factors (e.g., noise, light) that render them particularly vulnerable to poor sleep health. However, few studies have explored AI/AN adolescent sleep. To our knowledge, this is the first study to use systematic qualitative methods with AI/AN youth to explore their sleep environment and sleep behaviors. DESIGN In-depth interviews with 26 youth. SETTING Two urban areas in Central and Southern California. PARTICIPANTS Urban-dwelling AI/AN youth, age 12-16 years. INTERVENTION N/A. MEASUREMENT N/A. RESULTS We identified five main themes, each with subthemes: sleep patterns and desired sleep, sleep barriers inside the home, environmental factors, sleep facilitators, and cultural dimensions. Key concerns discussed were poor sleep hygiene, excessive use of electronics prior to bedtime, issues with temperature regulation, and noise both within and outside the home. Parents can be an important vehicle for messaging around sleep health and for behavior management. Participating adolescents also indicated differing levels of attachment to Native identity, suggesting that culturally-targeted sleep interventions should build in openness and flexibility to a range of identity starting points. Further, we identified cultural practices, such as sweat lodges and dreamcatchers, that could be incorporated in future sleep interventions for this population. CONCLUSION Findings increase our understanding of urban AI/AN youth's sleep environments and behaviors, thus potentially informing program development around sleep health for this vulnerable population.

Abstract
OBJECTIVE To investigate the association between energy drink (ED) use and sleep-related disturbances in a population-based sample of young adults from the Raine Study. DESIGN Analysis of cross-sectional data obtained from self-administered questionnaires to assess ED use and sleep disturbance (Epworth Sleepiness Scale, Functional Outcomes of Sleep Questionnaire (FOSQ-10) and the Pittsburgh Sleep Symptoms Questionnaire-Insomnia (PSSQ-I)). Regression modelling was used to estimate the effect of ED use on sleep disturbances. All models adjusted for various potential confounders. SETTING Western Australia. PARTICIPANTS Males and females, aged 22 years, from Raine Study Gen2-22 year follow-up. RESULTS Of the 1115 participants, 66 % were never/rare users (i.e. <once/month) of ED, 17·0 % were occasional users (i.e. >once/month to <once/week) and 17 % were frequent users (≥once/week). Compared with females, a greater proportion of males used ED occasionally (19 % v. 15 %) or frequently (24 % v. 11 %). Among females, frequent ED users experienced significantly higher symptoms of daytime sleepiness (FOSQ-10: β = 0·93, 95 % CI 0·32, 1·54, P = 0·003) and were five times more likely to experience insomnia (PSSQ-I: OR = 5·10, 95 % CI 1·81, 14·35, P = 0·002) compared with never/rare users. No significant associations were observed in males for any sleep outcomes. CONCLUSIONS We found a positive association between ED use and sleep disturbances in young adult females. Given the importance of sleep for overall health, and ever-increasing ED use, intervention strategies are needed to curb ED use in young adults, particularly females. Further research is needed to determine causation and elucidate reasons for gender-specific findings.

Abstract
Study Objectives There is contradictory evidence on whether sleep need decreases across adolescence. We investigated this question longitudinally with a dose-response design to test the effects of varied sleep durations on daytime sleepiness and on vigilance and to test whether these relations change with age across early and mid-adolescence. Methods Data from 76 participants who completed at least 2 years of the 3-year study are included in this report. Annually, participants ranging in age from 9.8 to 16.2 years completed three different time in bed (TIB) schedules each consisting of four consecutive nights of 7, 8.5, or 10 hours. Daytime sleepiness (multiple sleep latency test [MSLT]) and vigilance (psychomotor vigilance test [PVT]) were measured on the day following the fourth night of each TIB schedule. Results Electroencephalogram (EEG)-measured sleep durations changed linearly with TIB. MSLT-measured daytime sleepiness decreased with longer TIB and increased with age. The TIB and age effects interacted such that the TIB effect decreased with age. PVT performance improved with longer TIB and improved with age, but the benefit that increased TIB conferred on PVT performance did not change with age. Conclusions These results seem paradoxical because daytime sleepiness increased but vigilance improved with age. The significant age effect on the relation between TIB and sleepiness compared to the lack of an age effect on the relation between TIB and vigilance performance suggests different rates of maturation in underlying brain systems. We interpret these findings in relation to our model of adolescent brain development driven by synaptic elimination.
