Aims: The aim was to investigate changes in child and adolescent sleep habits in Sweden over time. This had not been done previously. Methods: Cross-sectional questionnaire data over three decades of investigations of the Health Behaviours of School Children study (1985/1986, 2005/2006 and 2013/2014) were used. The sample included 18,682 children and adolescents, aged 11, 13 and 15. Empirically based age-specific sleep duration recommendations were used to operationalise sleep duration. Results: The results showed that, over time, fewer go to bed early and more go to bed late. Regarding sleep duration, there have been decreases in the proportion of children and adolescents that sleep as much as is recommended for their age. Sleep onset difficulties have increased for all ages and increase the odds of sleeping less than recommended as well as having late bedtimes. Boys were more likely than girls to have later bedtimes and to sleep less than recommended. A vocational educational track, not planning to study further or being unsure of which track to choose increased the odds for 15 year olds to have late bedtimes and to sleep less than recommended compared with a college preparatory track. Conclusions: The results indicate that over time, fewer children and adolescents attain sufficient sleep duration. This may have implications for study results, mental health and cognitive abilities.

Objective: To examine the association between 25-Hydroxyvitamin D (25(OH)D) levels and sleep duration among Chinese adolescents. Subjects and methods: A school-based cross-sectional study was conducted among Chinese adolescents in 2017. Data on a total of 800 adolescents aged 8–14 years was used for this study. Anthropometric measurements such as height and weight were measured by trained research staff. Serum 25(OH)D and lipids were measured in the laboratory. Sleep habits and other health-related behaviors were tested by questionnaire. Results: 25(OH)D levels were significantly positively correlated with sleep duration (r = 0.11, p < 0.05). In multivariate logistic regression analyses, insufficiency/deficiency of vitamin D (25(OH)D ≤ 20 ng/mL) was significantly associated with increased probability of short sleep (AOR = 1.67, 95% CI = 1.14–2.43). Conclusions: Low 25(OH)D levels were independently associated with the risk of insufficient sleep in Chinese adolescents.

Abstract Study Objectives To evaluate how change in menopausal status related to spectral analysis and polysomnographic measures of sleep characteristics. Methods The Study of Women’s Health Across the Nation (SWAN) Ancillary Sleep Study evaluated sleep characteristics of 159 women who were initially pre- or early perimenopausal and repeated the assessment about 3 ½ years later when 38 were pre- or early perimenopausal, 31 late perimenopausal, and 90 postmenopausal. Participants underwent in-home ambulatory polysomnography for 2 to 3 nights. Average EEG power in the delta and beta frequency bands was calculated during NREM and REM sleep, and sleep duration, wake after sleep onset (WASO), and apnea hypopnea index (AHI) were based on visually-scored sleep. Results The women who transitioned to postmenopause had increased beta NREM EEG power at the second assessment, compared to women who remained pre-or early premenopausal; no other sleep measures varied by change in menopausal status. In multivariate models the associations remained; statistical controls for self-reported hot flashes did not explain findings. In secondary analysis, NREM beta power at the second assessment was greater among women who transitioned into the postmenopause after adjustments for initial NREM beta power. Conclusions Sleep duration and WASO did not vary by menopause transition group across assessments. Consistent with prior cross-sectional analysis, elevated beta EEG power in NREM sleep was apparent among women who transitioned to postmenopause, suggesting that independent of self-reported hot flashes, the menopausal transition is associated with physiological hyperarousal during sleep.

Obsessive compulsive disorder (OCD) is a common disorder characterised by persistent and unwanted intrusive thoughts, images, and urges and repetitive behaviours or mental acts and can cause pervasive impairments. In Bangladesh, the prevalence of OCD among children is 2% which is higher than in previous reporting. This study was aimed at looking into the type, frequency, and severity of symptoms of OCD and comorbidity among children and adolescents. A consecutive 60 OCD cases from a child mental health service with age range of 5–18 years were recruited and divided into below and above 12 years of age group. The assessment was carried out using standardized Bangla version of Development and Wellbeing Assessment and Children’s Yale-Brown Obsessive Compulsive Scale was administered. Of the obsession, contamination was the highest followed by doubt, and of the compulsion, washing/cleaning was the highest followed by checking, repeating, and ordering rituals. More than half of the subjects had severe OCD and comorbidity was present in 58% subjects. Specific phobia, social phobia, major depressive disorder, and tic disorder were more prevalent. These symptoms and comorbidity profile can serve the baseline data for a country like Bangladesh and further large scale study would better generalize the study results.

Sleep duration, either short or long, has been associated with diseases such as obesity, type-2 diabetes and cardiovascular diseases. Characterizing the prevalence and patterns of sleep duration at the population-level, especially in resource-constrained settings, will provide informative evidence on a potentially modifiable risk factor. The aim of this study was to explore the patterns of sleep duration in the Peruvian adult and adolescent population, together with its socio-demographic profile. This is a cross-sectional study, secondary analysis of the Use of Time National Survey conducted in 2010. Weighted means and proportions were used to describe sleep duration according to socio-demographic variables. Poisson regressions, taking into account the multistage sampling design of the survey, were used to calculate crude and adjusted prevalence ratios (PR) and 95% confidence intervals (95% CI). Main outcomes were short- (<6 hours) and long-sleep duration (≥9 hours). A total of 12,424 observations, mean age 35.8 years (SD ±17.7), 50.6% males, were included in the analysis. On average, Peruvians slept 7.7 hours (95% CI 7.4-8.0) on weekdays and 8.0 hours (95% CI 7.8-8.1) during weekends. The proportions of short- and long-sleep, during weekdays, were 4.3% (95% CI 2.9%-6.3%) and 22.4% (95% CI 14.9%-32.1%), respectively. Regarding urban and rural areas, a much higher proportion of short-sleep was observed in the former. On the multivariable analysis, compared to regular-sleepers (≥6 to <9 hours), short-sleepers were twice more likely to be older and to have higher educational status, and 50% more likely to be currently employed. Similarly, relative to regular-sleep, long-sleepers were more likely to have a lower socioeconomic status as per educational attainment. In this nationally representative sample, the sociodemographic profile of short-sleep contrasts the long-sleep. These scenarios in Peru, as depicted by sleeping duration, differ from patterns reported in other high-income settings and could serve as the basis to inform and to improve sleep habits in the population.

Abstract Introduction There is limited evidence about how sleep changes in children with Down syndrome (DS) following sleep interventions. This study evaluated changes in sleep over time in children receiving treatment comparing to a control group who did not. Methods Children with DS, 3-16yrs, attending the sleep clinic were followed for 24-months. Sleep parameters including parent completed child sleep habits questionnaire (CSHQ), PSG and home sleep diary were obtained pre and post sleep interventions for children undergoing treatment. Data was obtained at similar intervals for the control group who were followed over the same time period. Results Data was obtained for 41 participants, 16 children received an intervention and 25 did not. Interventions included ENT surgery (7), CPAP (4), melatonin (3) or a combination (2). The intervention group had a significantly higher average total CSHQ score overall than those in the control group (0.01). Scores decreased over time but remained higher than in controls throughout, and were clinically significant in both groups (&gt;41). Sleep diary estimated average total sleep duration did not differ between groups and was 10hrs/night. PSG showed improvement in OAHI in those children undergoing pre and post intervention studies. Discussion Evaluation of sleep parameters in this referred cohort of children with Down syndrome demonstrates total sleep duration in keeping with national recommendations and improvement in obstruction with treatment. However, CSHQ results indicate ongoing sleep difficulties reported by parents, despite standard sleep interventions. This may reflect persisting non-respiratory sleep disorders, which are not being adequately addressed at present.

Sleep is important to physical and mental development. Studies show that adolescents suffer from electronic media exposure-related inadequate and non-quality sleep. In Israel, traditional, conserva-tive Arab society is undergoing a modernization process with exposure to the Western lifestyle and Israeli Jewish culture. This comparative cross-sectional study compared electronic media exposure’s impact on sleep in secular Jewish and Arab society in Israel, involving 229 middle and high school adolescents, 118 Arabs and 111 Jews. Research tools were the School Sleep Habits Survey (SSHS) and a sociodemographic questionnaire. Jewish adolescents are more exposed to electronic media than are Arab adolescents only during mid-week. Weak but significantcorrelations were found between late night use of electronic media and sleep duration; increased exposure to television (r = -0.17, p = .01), mobile telephone r = -0.21, p = .002), and tablet (r = -0.14, p = .02) related to shorter sleep duration and longer sleep latency mid-week in both groups and later weekend wake-up time. Arab adolescents are sleepier during the day and have more sleep-related behavior problems. As electronic media exposure rises, sleep duration shortens, and sleep time is postponed in both cultures. Exposure to electronic media is higher among Jewish adolescents. Boys sleep longer than girls during the week (a difference of nearly an hour).

Abstract Background In order to study the high blood pressure of children and adolescents and its influencing factors, it provides evidence-based evidence for the high blood pressure prevention of primary and secondary school students. Methods This study is a cross-sectional survey, which uses stratified cluster sampling method to select students from 7 schools to participate in questionnaire survey and physical examination. The correlation between single factor and high blood pressure was analyzed by chi-square test, and multivariate logistic regression analysis was used for multivariate analysis. Results A total of 1,814 subjects, including 512 primary school students (28.22%), 499 junior high school students (27.51%), 563 senior high school (31.04%), and 240 vocational high school (13.23%). There were 1000 males (55.13%) and 814 females (44.70%). The average age was 13.64±2.65 years. The detection rate of high blood pressure was 9.76%. Multivariate logistic regression analysis showed that the age groups were 10~ and 14~ (OR=20.870, 95%CI=2.372-183.666; OR=10.049, 95%CI=1.306-77.353) , sleep duration < 7h (OR=4.136, 95%CI=4.136), and physical education class times ≤2 times per week (OR=5.073, 95%CI=2.497-10.306), which were risk factors for high blood pressure in children and adolescents. Normal weight and overweight group were protective factors compared to the obesity group (OR=0.094, 95%CI=0.061-0.146; OR=0.225, 95%CI=0.134-0.378). Conclusion The age groups of 14~ and 16~ years old, physical education classes ≤ 2 times per week, and sleep duration <7h were risk factors for primary and secondary school students, and BMI of Normal weight and overweight group were protective factors compared to the obesity group students.

ObjectivesWe estimated the prevalence of short sleep duration and multimorbidity in Luxembourg, and assessed whether sleep duration was associated with multimorbidity after adjusting for sociodemographic and behavioural characteristics.DesignCross-sectional study.ParticipantsData from 1508 Luxembourg residents (48% men and 52% women) aged 25 to 64 years came from the European Health Examination Survey 2013–2015.Outcome measuresShort sleep duration and multimorbidity.ResultsParticipants reported sleeping 6.95 hours/night during work days, nearly 1 hour less than during non-work days (7.86 hours/night). Nearly half of participants reported having been diagnosed with ≥2 chronic conditions/diseases. Short sleep duration was associated with the number of chronic conditions (OR 4.65, 95% CI 1.48 to 14.51; OR 7.30, 95% CI 2.35 to 22.58; OR 6.79, 95% CI 2.15 to 21.41 for 1, 2 and ≥3 chronic conditions/diseases, respectively), independently of socioeconomic and behavioural characteristics.ConclusionsHealth promotion programmes should aim at improving and promoting healthy lifestyles among the general population to improve sleep habits as well as decrease multimorbidity in middle-aged adults.
