Sleep problems are common in adolescence with a negative impact on the mental health and functioning of adolescents. However, the roles of different sleep problems in relation to emotional and behavioural problems (EBPs), classified according to the 10th version of the International Classification of Diseases as emotional, conduct, hyperactivity and social functioning disorders, are not clear. The first aim of the study was to investigate the association between difficulties in getting to sleep and EBPs in adolescents. The second aim was to explore the role of sleep duration in this association. We used data from the Health Behaviour in School-aged Children (HBSC) study conducted in 2018 in Slovakia. Presented are results for specific age groups of 13-year-old (N = 1909) and 15-year-old (N = 1293) adolescents. Subjective measures of sleep variables were used. Binary logistic regression models adjusted for age and gender were used to assess associations between difficulties in gettin...

We aimed to describe the sleep profiles and associated factors of poor sleep in adolescents. We gave a sleep questionnaire and Strengths and Difficulties Questionnaire to 3,441 high school adolescents (15-18 years) in Gaziantep, Turkey. Adolescents reported a requirement of 10.4 hours of sleep on average to feel their best during the day. However, total night sleep time (TNST) was 7.42 +/- 1.48 hours on school nights and 9.40 +/- 1.37 on non-school nights. TNST of > or =9 hours on both school nights and non-school nights was detected in 8.2%. Average bedtime and wake-up time were 23:16 and 06:41 on school nights. Bedtime was approximately 30 minutes later on non-school nights. The shift in wake-up time was nearly 2.5 hours. Statistical analysis by logistic regression model showed that TNST was most significantly correlated with school start time (morning versus afternoon) irrespective of school or non-school nights. TNST on school nights was negatively correlated with age, passiv...
Trends in sleeping difficulty among adolescents in five Nordic countries 2002-2014
Nordisk välfärdsforskning | Nordic Welfare Research, 2019
Sleep has been found to be an important factor in adolescents' mental and physical health. The aim of the present study was to examine trends in sleep difficulty (i.e., difficulty falling asleep more often than once a week) in the Nordic countries among 11-to 15-year-olds. We analysed Nordic data from the Health Behaviour in School-aged Children study (HBSC), which is conducted every four years, looking specifically at trends in sleep difficulty over a 12-year period from 2002 to 2014. The participants were aged 11 to 15 years. The total number of participants across these years was 113,447. A large percentage (17% to 31% in 2014) of adolescents in the Nordic countries experience sleep difficulty, and these difficulties increased from 2002 to 2014 in Denmark, Finland, Iceland, and Sweden. Only in Norway was there a decrease, mainly due to a reduction in sleep difficulty among 11-year-old boys and girls from 2010 to 2014. Sleep difficulty among boys and girls are prevalent and generally on the rise in the Nordic countries with the exception of Norway.
Sleep patterns and insomnia among adolescents: a population-based study
Journal of Sleep Research, 2013
The aim of the current study was to examine sleep patterns and rates of insomnia in a population-based study of adolescents aged 16-19 years. Gender differences in sleep patterns and insomnia, as well as a comparison of insomnia rates according to DSM-IV, DSM-V and quantitative criteria for insomnia, were explored. We used a large population-based study in Hordaland county in Norway, conducted in 2012. The sample included 10 220 adolescents aged 16-18 years (54% girls). Self-reported sleep measurements included bedtime, rise time, time in bed, sleep duration, sleep efficiency, sleep onset latency, wake after sleep onset, rate and frequency and duration of difficulties initiating and maintaining sleep and rate and frequency of tiredness and sleepiness. The adolescents reported short sleep duration on weekdays (mean 6:25 hours), resulting in a sleep deficiency of about 2 h. A majority of the adolescents (65%) reported sleep onset latency exceeding 30 min. Girls reported longer sleep onset latency and a higher rate of insomnia than boys, while boys reported later bedtimes and a larger weekday-weekend discrepancy on several sleep parameters. Insomnia prevalence rates ranged from a total prevalence of 23.8 (DSM-IV criteria), 18.5 (DSM-V criteria) and 13.6% (quantitative criteria for insomnia). We conclude that short sleep duration, long sleep onset latency and insomnia were prevalent in adolescents. This warrants attention as a public health concern in this age group.
Insomnia is the most common sleep disorder in the adolescent population. Caused by genetic, biological, social and environmental factors, it affects disturbances in everyday functioning in many aspects of life. The aim of the study was to analyze the factors related to the occurrence of insomnia among high school students. Material: The study was conducted among 2364 high school students aged between 14 to 19 years old (the average age 17.92±1.10), of which there were 2068 girls and 295 boys. Method: Athens Insomnia Scale (AIS) and authorial demographic data questionnaire involved questions about physical activity during the day, smoking, frequency of upper respiratory tract infections, problems with concentration and memory, school achievements, and the use of mobile devices at bedtime were used to assess examined parameters. The scale and questionnaires were shared on-line via social media. Results: Analyzing the results obtained in the study group, the average score of 8.42±4.16 ...
Impact of Adolescents’ Sleeping Problems and Habits on the Quality of Their Sleep
Journal of Turkish Sleep Medicine, 2021
Amaç: Bu çalışmada adölesan dönemdeki uyku problemlerinin ve alışkanlıklarının uyku kalitesine etkisini belirlemek amaçlanmıştır. Gereç ve Yöntem: Türkiye'de öğrenim gören 820 lise öğrencisine, Pittsburgh Uyku Kalitesi indeksi (PUKİ) uygulandı. Elde edilen veriler bilgisayar ortamında değerlendirildi. Bulgular: Araştırmaya katılan adölesanların yaş ortalaması 16±1,14 yıl olup, %50,37'si kötü uyku kalitesine sahipti. Alkol/sigara kullanımı (p=0,001), internette gezinme (p=0,000), TV seyretme (p=0,026), yatmadan önce yiyecek tüketme (p=0,003) ile PUKİ toplam puan arasında istatistiksel olarak anlamlı fark vardı (p<0,05). Regresyon analizinde uykuya dalmakta zorlanma durumu arttıkça PUKİ puanı 2,5 kat, uykuda sıçrayarak uyanma ve sigara kullanma durumu arttıkça PUKİ puanı 1,6 kat arttı. Sonuç: Çalışmaya katılan adölesanların yarıdan fazlasının uyku kalitesi düşüktür. Adölesanın uyku ile ilgili problemleri onların fiziksel ve duygusal sağlığı, akademik başarısı ve güvenliği için ciddi bir risk oluşturmaktadır. Bu nedenle adölesanların uyku rahatlığını etkileyecek faktörlerin en aza indirilmesi ve adölesan uyku sağlığının okul sağlığı ekiplerince geliştirilmesi gerekmektedir. Anahtar Kelimeler: Adölesan, uyku kalitesi, okul sağlığı, hemşirelik Objective: This study aimed to determine the impact of adolescents' sleeping problems and habits on the quality of their sleep. Materials and Methods: The Pittsburgh Sleep Quality index (PSQI) was administered to a group of 820 high school students in Turkey. A computerised assessment was made of the data obtained. Results: The mean age of the participating adolescents was 16±1.14 years, 50.37% of whom had poor sleep quality. Statistically significant differences (p<0.05) were noted in their overall PSQI scores in terms of their use of alcohol/cigarettes (p=0.001), surfing the internet (p=0.000), watching TV (p=0.026) and eating something before going to bed (p=0.003). Based on the regression analysis, as the difficulty in falling asleep increases, the PSQI score is 2.5 times; as the state of waking up by jumping increases, the PSQI score is 1.6 times and as the smoking status increases, the PSQI score is 1.6 times. Conclusion: More than half of the participating adolescents had poor sleep quality. Sleep-related problems present serious risks in terms of adolescents' physical and emotional health, academic achievement and safety. Because of this, factors that may disturb adolescents' sleep patterns must be kept to a minimum, and school health teams need to promote healthy sleep habits among adolescents.
Sleep patterns and insomnia among portuguese adolescents: a cross-sectional study
Atención Primaria, 2014
Introduction: Inadequate sleep patterns and insomnia are frequently linked and represent common sleep disorders among adolescents. The present study provides data on sleep patterns and insomnia among Portuguese adolescents. Material e methods: In a cross-sectional study we evaluated 6,919 students from the 7th to the 12th grade from twenty-six secondary schools. Data was collected using a self-administered questionnaire. Insomnia was de ned based on the Diagnostic and Statistical Manual of Mental Disorders IV criteria and daytime sleepiness was assessed with the Epworth Sleepiness Scale. Sleep patterns evaluated both sleep duration ("insuf cient" sleep was de ned as < 8 hours per night) and bedtime schedules and regularity. Results: The prevalence of insomnia was 8.3%, insomnia symptoms 21.4% and insuf cient sleep 29.3%. All prevalence were higher among girls (P < .001). Average sleep time, on weeknights, was 8:04 ± 1:13 hours. On average adolescents went to bed at 22:18 ± 1:47 hours, took 21 minutes to fall asleep and woke up at 7:15 ± 0:35 hours. Only 6.4% of adolescents stated having a regular bedtime. The majority of adolescents (90.6%) reported having dif culty waking up, 64.7% experienced daytime sleepiness and 53.3% experienced sleep during classes. Conclusions: There are high prevalence of inadequate sleep patterns, insuf cient sleep and insomnia among Portuguese adolescents. Insuf cient sleep is associated with sleep patterns and social and behavioural factors. These results add to our knowledge of adolescent sleep worldwide.
Sleep characteristics of adolescents: A longitudinal study
Journal of Adolescent Health, 1993
The aim of the present research was to study sleep/wake cycle parameters of adolescents and to examine biologic and social influences on their changing sleep patterns. This was a longitudinal study of sleep characteristics of a group of 66 adolescents (mean age, 13 years and 6 months). The adolescents underwent a physical examination, had their pubertal development classified according to Tanner stages, and answered a sleep questionnaire on three timepoints at 6-month intervals. Sleep onset occurred about 1.0 hr later, wake-up time about 3.0 hr later, and sleep length was 1.0-1.5 hr longer on weekends when compared with weekdays. About 60% of the adolescents reported daytime sleepiness, mainly from 8:00 a.m. to 10:00 a.m. and from 2:00 p.m. to 4:00 p.m. on school days. Morning sleepiness on school days occurred at a time of the day that corresponded to sleep on non-school days. Additionally, there was a displacement toward later hours of the wake-up time and a sleep-length increase during weekends from the first to the third timepoint. Social factors such as home conditions and scheduling of school and non-school activities did not change throughout the period of pubertal development studied. Changes of sleep patterns detected may therefore represent an ontogenetic trend along puberty.
