Reasons for sleeping difficulties as perceived by adolescents: a content analysis

Adolescents' Suggestions on how to Support Their Sleep: A Focus Group Study

Sleeping difficulties among adolescents constitute a pressing public health issue, and it is of the utmost importance that these are approached from a health-promotion perspective. This study explores adolescents' suggestions on how their sleep could be supported. Data were collected via eight focus group interviews with 43 adolescents aged 15-16, in Sweden, and analyzed using qualitative content analysis. The results describe the adolescents' suggestions on how their sleep could be supported in three themes: being supported by involved parents- routines, engagement, and warmth are vital; being supported to achieve knowledge on the "whys" and "hows" of sleep-increased knowledge gives the ability to make well-grounded sleep choices; and being guided into finding balance-balance in life is difficult to achieve and adolescents desire support. Parents, school nurses, health professionals, and anyone who has the opportunity to improve and promote sleep should consider adolescents' suggestions.

Adherence to sleep recommendations is associated with higher satisfaction with life among Norwegian adolescents

BACKGROUND

Sleep plays a crucial role in the health and well-being of adolescents; however, inadequate sleep is frequently reported in numerous countries. This current paper aimed to describe sleep duration, factors impacting sleep, consequences of insufficient sleep and satisfaction with life in Norwegian adolescents, stratified by sex and by adherence to the 8-hour sleep recommendation, and to examine potential associations between adherence to the 8-hours sleep recommendation and satisfaction with life.

METHODS

This is a cross-sectional study using data from the Norwegian Ungdata Survey, collected in 2021. Adolescents from five Norwegian counties were included, comprising a total of 32,161 upper secondary school students. Study variables were collected through an electronic questionnaire administered during school hours and all data are anonymous. Descriptive data of sleep patterns are presented, and linear regressions were conducted adjusting for SES, perceived stress, physical activity level, over-the-counter analgesics use, grade level and screen time.

RESULTS

73% of adolescents did not adhere to the 8-hours of sleep recommendation per night, with similar results for girls and boys. 64% reported tiredness at school (minimum 1-2 days weekly) and 62% reported that screen time negatively affected their ability to sleep. 23% reported that gaming affected their sleep, with a higher prevalence in boys than girls. Satisfaction with life score was 7.0 ± 1.9 points (out of 10) for the total sample, with higher scores for boys (7.3 ± 1.8 points) than girls (6.9 ± 1.9 points). Regressions revealed a positive association with satisfaction with life (B = 0.31, 95% [0.15 to 0.48]) in adolescents adhering to sleep recommendation of 8h compared to the ones not adhering to the sleep recommendation.

CONCLUSIONS

Most Norwegian adolescents fail to adhere to the 8-hours of sleep recommendation and the majority feel tired at school or during activities. More than half of adolescents reported that screen time negatively affected their ability to sleep. Adhering to the sleep recommendation was associated with higher life satisfaction. Our findings highlight the importance of sufficient sleep in adolescents, while future research is needed to examine other sleep related measures on adolescents´ satisfaction with life.

Determining adolescent health information needs: A survey in Geneva, 2022

Purpose

When adolescents feel that their opinions are valued and respected, they are more likely to seek and use health services. Our aim was to identify what health information adolescents in Geneva, Switzerland, want and how much they are willing to participate in health promotion, linking it to international recommendations.

Method

Data were collected from 970 adolescents (aged 12-15 years), between September and November 2022, using a classroom-based survey.

Results

Adolescents expressed their preferences: the study showed that the topics of sleep, self-perception, biology, mental health, and physical activity received the highest interest. Girls were more interested than boys in the issues of sleep, mental health, violence, and social life. Adolescents' increasing interest in sexuality issues as they get older is inversely proportional to their interest in other issues such as pandemics, medical research, and the environment, which they are more interested in during early adolescence. Everyone over two felt it was important to promote health in their social environment. And more than a third of teens are open to participating in such activities.

Discussion

Adolescents are open to various health subjects, except for pandemics. Age dependent interest highlights the importance of tailoring intervention programs. Adolescents consider health promotion important and are willing to participate, as recommended by the World Health Organization. By involving them as experts in their adolescence, we have taken an essential step. We strongly recommend continuing involving and trusting adolescents in shaping future interventions.

Associations between sleep habits, quality, chronotype and depression in a large cross-sectional sample of Swedish adolescents

OBJECTIVE

To investigate behavioral sleep habits, self-perceived quality of sleep, and chronotype, and to examine their association with clinically relevant levels of depression in Swedish adolescents.

METHOD

Questionnaire data were obtained from a representative sample of Swedish adolescents (n = 8449; 50.8% girls; aged 12-16). Depression was defined as >13 BDI-II scores. Logistic regression modelling estimated the effects of sleep duration, sleep quality, and chronotype on depression, adjusted for socio-demographic factors.

RESULTS

On weekdays, approximately 46% of adolescents slept less than the recommended length of eight hours per night (depressed: 68%, non-depressed: 40%). On weekends, however, only 17% slept shorter than recommended. Short weekday sleep duration was more common among girls than boys (53% vs. 38%) and girls reported worse sleep quality. The regression model showed that depression was predicted by weekday sleep duration (OR = 0.773, p < .0001), sleep quality (OR = 0.327, p < .0001), and late chronotype (OR = 1.126, p = .0017), but not by weekend sleep duration. A 30-minute increase in weekday sleep duration was associated with about 10% lower odds of depression.

CONCLUSIONS

A substantial proportion of Swedish adolescents do not seem to meet the sleep recommendations of eight hours per night. Short sleep duration on weekdays, poor sleep quality, and late chronotype were associated with increased risk of depression. Interventions promoting longer weekday sleep duration (e.g., later school start times) seem relevant in this context, but further research is needed to investigate the directionality and underlying mechanisms of these associations.

Sleep quality and its relationship with school schedules and mental health of Nigerian secondary school adolescents

STUDY OBJECTIVES

This study aimed to determine the sleep quality of in-school Nigerian adolescents and its association with their schooling and mental health outcomes.

METHODS

The study was a descriptive cross-sectional study. It was conducted among adolescents attending public and private secondary schools within the Ife Central Local Government, Osun State, southwestern Nigeria. A multistage sampling technique was used to select study participants. The Pittsburgh Sleep Quality Index, 9-item Patient Health Questionnaire (PHQ-9), and 7-item General Anxiety Disorder questionnaires were used to determine sleep quality, depression, and anxiety, respectively.

RESULTS

We studied 448 adolescents aged between 10 and 19 years with a mean age of 15.0 ± 1.8 years. The majority of our respondents (85.0%) had poor sleep quality. More than half of the respondents (55.1%) had insufficient sleep during weekdays, while only 34.8% had insufficient sleep during weekends. The school closing time and school type showed a statistically significant association with sleep quality (P = .039 and .005, respectively). The odds of having poor sleep quality increased by 2-fold among adolescents in private schools when compared with those in public schools (adjusted odds ratio = 1.97, 95% confidence interval = 1.069-3.627). Using multiple linear regression, only depression showed a statistically significant association with sleep quality at 95% confidence interval (CI = 0.073 to 0.219, P < .001), such that for every unit change in depression scores (PHQ-9), there will be a corresponding increase of 0.103 in sleep quality.

CONCLUSIONS

Sleep quality is poor in adolescents and adversely associated with their mental health. This should also be addressed in the development of appropriate interventions.

A systematic review of Nightmare prevalence in children

The purpose of this narrative review was to describe prevalence rates of nightmares and nightmare disorder in school-aged youth according to sample characteristics and methods used to assess nightmares. We searched PsychINFO, PubMed, and CINAHL databases to identify empirical peer-reviewed articles and grey literature published between 2001 and 2021. Sixty-nine studies from 23 countries were included. The prevalence of nightmares was between 1% and 11% in the past week and 25% to 35% in the past month in pediatric developmental samples and between 27% and 57% in the past week and 18%-22% in the past month in psychiatric samples. The prevalence of nightmare disorder was approximately between 3% and 6% in pediatric developmental samples and 10%-12% in psychiatric samples. Nightmare prevalence peaks between ages 10 and 14 then decreases with older age. Generally, prevalence was higher in girls than boys, and one study suggested gender divergence started around age 14. Children's self-reports were higher than parent reports, except in samples with comorbid psychiatric problems where there was more parent-child agreement. Inconsistencies in nightmare definitions and measurement were observed across the literature and indicate a need for standardized measurement of nightmares.

Sleep duration in schooldays is associated with health-related quality of life in norwegian adolescents: a cross-sectional study

BACKGROUND

Insufficient sleep is commonly reported in adolescence and is negatively associated with a wide range of health outcomes. A way to grasp the complicated challenge of how sleep impact different aspects of the adolescents´ everyday life is by examining the relationship between sleep duration in schooldays and weekends on different health-related quality of life (HRQOL) subscales. Furthermore, to expand the understanding of possible underlying mechanisms between sleep and HRQOL, testing for self-efficacy as a possible mediator is of importance.

METHODS

A cross-sectional study was performed among 696 adolescents aged 13-15 years from a school-based setting. All participants completed an electronic survey in their respective classrooms. The survey included demographic data, the School Sleep Habits Survey, the KIDSCREEN-27 questionnaire measuring HRQOL, and the General Perceived Self-Efficacy Scale. Statistical analyses were conducted using SPSS Statistics software including PROCESS macro by Andrew Hayes.

RESULTS

Our findings revealed overall similar sleep patterns in boys and girls including longer sleep duration in the study sample during weekends (10:09 h) than in schooldays (08:36 h). Regression analyses revealed that sleep duration in schooldays was positively and statistically associated with HRQOL subscales psychological well-being (95% CI [0.44 to 1.33]), autonomy and parents (95% CI [0.12 to 1.06]), school environment (95% CI [0.47 to 1.40]), and self-efficacy (95% CI [0.01 to 0.47]). Sleep duration in weekends revealed no associations with the HRQOL subscales, except for the HRQOL subscale psychological well-being (95% CI [0.09 to 0.85]). Mediation analyses revealed that sleep duration in schooldays explained most of the associations (64 - 75%) in 4 out 5 HRQOL subscales, except in the association with the HRQOL subscale physical well-being revealing an indirect effect of 71.9%.

CONCLUSIONS

This cross-sectional study described sleep among Norwegian adolescents and demonstrated that sleep durations in weekends and schooldays impact HRQOL and self-efficacy, revealing overall better outcome in HRQOL and self-efficacy with sufficient sleep during schooldays. These findings support the regularity of sleep and highlight the importance of sufficient sleep during schooldays, especially in a school-based sample of adolescents.

Eating habits matter for sleep difficulties in children and adolescents: A cross-sectional study

Background

Sleep difficulties are a common sleep-related problem among children and adolescents. However, the association between eating habits and sleep difficulties has not been extensively studied. Therefore, this study aimed to investigate the relationship between eating habits and sleep difficulties in children and adolescents.

Methods

This study utilized cross-sectional data from the 2013/2014 Health Behaviour in School-aged Children survey. A total of 213,879 young adolescents provided self-reported information on their weekday and weekend breakfast consumption, fruit and vegetable intake, sweet and soft drink consumption, and sleep difficulties. Covariates such as sex, age, family affluence, physical activity, and body mass index were also assessed. Multilevel generalized linear modelling was used to analyse the association between independent and dependent. Results were reported as odds ratios (OR) with 95% confidence intervals.

Results

Of all study participants, approximately 50% were girls. Regression models indicated that more frequent breakfast consumption was associated with fewer sleep difficulties (e.g., consuming breakfast on weekdays for 5 days: OR = 1.49, 95% CI: 1.45-1.54). Fruit and vegetable consumption once a week or more was also linked to fewer sleep difficulties (all OR > 1.08, ≥ 1.07). In addition, consuming fewer sweets and soft drinks was generally associated with fewer sleep difficulties.

Conclusion

This study provides evidence supporting the association between healthier eating habits and reduced sleep difficulties in children and adolescents. Future research using longitudinal or experimental designs is encouraged to confirm or negate these findings. Additionally, this study offers practical guidance for nutritional counselling professionals and sleep health promotion practitioners.

Sleep apnea in people with Down syndrome: Causes and effects of physical activity?

Poor sleep quality is recognized as a major risk factor for poor health, increasing the incidence of serious chronic diseases. In people with Down syndrome, sleep apnea prevalence is significantly greater, it is caused by genetic, anatomical, endocrine, and metabolic abnormalities. The consequences of sleep disruption due to sleep apnea are very serious, especially in terms of neurocognitive and cardiovascular effects, leading to reduced life expectancy and quality of life in this population. However, the management, care, and treatment of related disorders in people with Down syndrome are still inadequate and limited. Therefore, this article wants to increase understanding and awareness about sleep apnea and the benefits of physical activity in improving sleep quality in the Down syndrome community, families, and their care specialists.

Adolescent sleep duration: associations with social‐cognitive determinants and the mediating role of sleep hygiene practices

Insufficient sleep duration among adolescents is a widespread public health problem. Gaining better insight into social-cognitive determinants associated with adolescent sleep duration is necessary for developing effective preventive interventions to support healthy sleep. This study aimed to explore whether social-cognitive determinants regarding sufficient sleep duration were associated with sleep duration, and if these associations were mediated by collective sleep hygiene practices. Furthermore, we examined these associations for social-cognitive determinants related to not using media before bedtime and doing relaxing activities and considered whether these associations were mediated by specific sleep hygiene practices. Data were collected amongst second- and third-grade adolescents from 10 Dutch high schools. A total of 878 adolescents (mean [SD] age 13.3 [0.71] years) completed data on sleep duration, social-cognitive determinants of the Theory of Planned Behaviour (i.e., attitude, subjective norms from parents, subjective norms from peers, perceived behavioural control, intention), and sleep hygiene practices. Single- and multivariable path models were constructed and mediation by sleep hygiene practices was analysed by Monte Carlo simulation. All social-cognitive determinants except for subjective norms from peers were associated with longer sleep duration (p < 0.01). Sleep hygiene practices mediated all associations between social-cognitive determinants and sleep duration (mediation ranging from 16% to 72%). Although some of the significant associations and mediation disappeared in the multivariable model, behavioural arousal was the strongest mediator, but collective sleep hygiene practices and cognitive/emotional arousal also explained parts of the associations. The findings indicate that social-cognitive factors should not be overlooked when targeting adolescent sleep duration.

"I Want to Sleep, but I Can't": Adolescents' Lived Experience of Sleeping Difficulties

Sleeping difficulties are increasingly prevalent among adolescents and have negative consequences for their health, well-being, and education. The aim of this study was to illuminate the meanings of adolescents' lived experiences of sleeping difficulties. The data were obtained from narrative interviews with 16 adolescents aged 14-15 in a Swedish city and were analyzed using the phenomenological hermeneutic method. The findings revealed four themes: feeling dejected when not falling asleep, experiencing the night as a struggle, searching for better sleep, and being affected the next day. The comprehensive understanding illuminates that being an adolescent with sleeping difficulties means it is challenging to go through the night and to cope the next day. It also means a feeling of being trapped by circumstances. As the adolescents' lived experiences become apparent, the possibility for parents, school nurses, and other professional caregivers to support adolescents' sleep increases.

School nurses’ experiences of health-promoting work to prevent stress in Swedish adolescents

Aim

To investigate school nurses’ experiences of health-promoting work to prevent stress in Swedish adolescents.

Materials and methods

Swedish school nurses (n = 225) responded to a web survey with open-ended questions. The results were subjected to a qualitative content analysis.

Results

Six categories were identified from the analysis: (1) Knowledge of body and soul, (2) Identifying stress and ill health, (3) Collaborative working within/outside school, (4) Make yourself (i.e., school nurses) visible to the students, (5) Support students’ learning, and (6) Tools for stress management. One of the most important themes in preventing and counteracting stress in school-aged children and adolescents was promoting healthy living habits. That school nurses were easily accessible and visible were important for them to identify stress as early as possible. The close collaboration with the school health care team and building relationships with the students were emphasized. The stress in adolescents was largely linked to schoolwork and performance anxiety. To counteract this, the dialogue with the teachers was important to increase their knowledge of mental health problems and stress and influence the scheduling of school exams.

Conclusion

The study contributes to increased knowledge in the field and provides concrete strategies for how school nurses can work to counteract stress in students.

Sleep Difficulties among Mexican Adolescents: Subjective and Objective Assessments of Sleep

OBJECTIVE/BACKGROUND

Self-reported sleep difficulties, such as insomnia symptoms, have been reported among adolescents. Yet, studies of their prevalence and correlates are scarce among Latin Americans. This study sought (1) to describe associations between sociodemographic and lifestyle factors with self-reported sleep difficulties and (2) to examine associations between self-reported sleep difficulties and actigraphy-based sleep.

PARTICIPANTS

Participants included 477 Mexican adolescents from the ELEMENT cohort.

METHODS

Over 7 days, self-reported sleep measures (hard time falling asleep, overall sleep difficulties, and specific types of sleep difficulties) were obtained from daily sleep diaries. Actigraphy-based sleep measures (duration, i.e. sleep onset to morning wake, midpoint, and fragmentation) were concurrently assessed using a wrist actigraph.

RESULTS

Mean (SD) age was 15.9 (2.2) years, and 53.5% were females. Mean (SD) sleep duration was 8.5 (1.2) h/night. Half reported a hard time falling asleep at least 3 days, and 25% had sleep difficulties at least 3 days over 7 days. The 3 types of sleep difficulties commonly reported among the entire cohort were insomnia/restlessness (29%), environmental (27%), and mental/emotional difficulties (19%). Female sex, smoking behavior, and socioeconomic indicators were among the most consistent factors associated with sleep difficulties. Subjective sleep difficulties were associated with shorter sleep duration (β = -20.8 [-35.3, -6.2] min), while subjective hard time falling asleep was associated with longer sleep duration (β = 11.3 [4.6, 27.2] min).

CONCLUSION

A high proportion of Mexican adolescents in the sample reported sleep difficulties. Findings demonstrate the importance of obtaining subjective and objective sleep measures for a more comprehensive assessment of adolescent sleep.

Association between Physical Activity and Sleep Difficulties among Adolescents in Germany: The Role of Socioeconomic Status

We examined sleep difficulties among adolescents in Germany and the association with physical activity (PA). Furthermore, we analyzed whether the association varied with the socioeconomic status (SES) among adolescent girls and boys in Germany. Using data from the German Health Interview Examination Survey for Children and Adolescents (KiGGS) study (Wave 2), 6599 adolescents aged 11 to 17 years were included in the analyses. We conducted sex-stratified logistic regression analyses. Dependent variables were unrecommended sleep duration (defined as a duration of sleep that does not meet the recommended duration), sleep-onset difficulties, trouble sleeping, and daytime sleepiness. Most adolescent girls and boys reported sleep difficulties. While no associations between PA and sleep difficulties were observed, a significant interaction between PA and SES was found for sleep duration in boys and daytime sleepiness in girls. Thus, adolescents with low SES had fewer sleep difficulties if they met the recommendation for PA, compared with those in other SES groups. In Germany, a large proportion of adolescents have sleep difficulties. We found that the experience of sleep difficulties varied according to PA, sex, and the family SES. Future sleep promotion programs should consider these differences.

Psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance and Sleep-Related Impairment item banks in adolescents

Sleep problems have a high prevalence and negative daytime consequences in adolescents. Current sleep measures for this age group have limitations. The Patient‐Reported Outcomes Measurement Information System (PROMIS^®) developed sleep item banks for adults. In a previous validation study, these item banks were adapted to a shortened version for adolescents. The current study aimed to further explore the psychometric properties of the 11‐item Sleep‐Related Impairment and 23‐item Sleep Disturbance item banks in Dutch adolescents. We investigated structural validity by testing item response theory assumptions and model fit; measurement invariance by performing differential item functioning analyses; performance as a computerized adaptive test; reliability by marginal reliability estimates and test–retest reliability (intraclass correlation coefficients and limits of agreement); and construct validity by hypothesis testing. Additionally, we provide mean values for the item banks. The study sample consisted of 1,046 adolescents (mean age 14.3 ± 1.6), including 1,013 high‐school students and 33 sleep‐clinic patients. The Sleep Disturbance‐23 showed lack of unidimensionality, but had sufficient test–retest reliability, and could distinguish between adolescents with and without sleep or health issues. The Sleep‐Related Impairment‐11 showed sufficient unidimensionality and model fit and was thus tested as a computerized adaptive test, demonstrating an equal amount of reliable measures to the full item bank. Furthermore, the Sleep‐Related Impairment‐11 could distinguish between adolescents with and without sleep or health issues and test–retest reliability was moderate. The use of both item banks in the full form and the use of the Sleep‐related Impairment‐11 as a computer adaptive test is recommended.

Reasons for sleeping difficulties as perceived by adolescents: a content analysis

Sleeping difficulties are increasingly prevalent among adolescents worldwide and have negative consequences for adolescent health and education. The aim of this study was to describe the reasons for sleeping difficulties as perceived by adolescents. Sleeping difficulties include insufficient sleep, trouble falling asleep, waking up at night or sleep that does not leave an individual rested. Data were collected in 2015 using an open‐ended question. The sample consisted of n = 475 adolescents from a city in Sweden, aged 15–16 years, with self‐assessed sleeping difficulties. The results described the reasons for the adolescents’ sleeping difficulties, at a general, thematic level, as an imbalance between requirements and preconditions, distributed to stress, technology use, poor sleep habits, existential thoughts, needs and suffering. To find a balance in their daily lives, adolescents may need support from parents, school nurses and school health services to deal with their sleeping difficulties.
