“…This is in line with previous studies that reported sleep duration became shorter during adolescence (Fallone et al, 2002;Iglowstein et al, 2003). Variation in sleep duration was accounted for by genetic, shared environmental, and non-shared environmental factors.…”

This study assessed to what extent genetic and environmental factors contributed to individual differences in adolescent sleep duration, and whether genetic and environmental contributions to sleep duration changed throughout adolescence. A twin-family design was used to gain insight into the genetic and environmental contributions to variation in sleep duration. The study sample consisted of 6,319 adolescent twins (44% males) and 1,359 non-twin siblings (44% males) in the age range of 12 to 20 years (mean age = 16.85, SD = 1.40). The participants self-reported usual sleep duration, which was categorized as less than 8 hours per night, 8-9 hours per night, and more than 9 hours per night. Results showed that the prevalence of shorter than optimum sleep duration, that is, less than 8 hours per night, was high, with the highest prevalence rates in later adolescence. The contribution of genetic and environmental factors to individual differences in sleep duration was dependent on age. Variation in sleep duration at the age of 12 years was accounted for by genetic (boys: 34%, girls: 36%), shared environmental (boys: 28%, girls: 45%), and non-shared environmental factors (boys: 38%, girls: 19%). At the age of 20 years, the role of genetic (boys: 47%, girls: 33%) and non-shared environmental factors (boys: 53%, girls: 67%) was more pronounced. It can be concluded from the results that individual differences in sleep duration were accounted for by genetic and non-shared environmental factors throughout adolescence, whereas shared environmental factors account for a substantial part of variation during early adolescence only.

“…The average sleep durations in the present study, as categorized by age, were lower than the US references 33 and the recommendations of the Chinese government (at least 10 h for children <10 years old, 9 h for 11-14 years old, and 8 h for >15 years old).…”

“…BP was classified using the population-based percentiles. 32,33 Normal BP was defined as SBP and/or DBP <90th percentile for age, sex, and height; prehypertension was defined as SBP and/or DBP 90th and <95th percentile for age, sex, and height, or if the SBP was more than 120 mmHg or DBP was more than 80 mmHg. Hypertension (HTN) was defined as SBP and/or DBP 95th percentile.…”

Background: Short sleep duration was reported to be associated with an increased risk of hypertension among adults. The present study aimed to investigate this association in children and adolescents. Hypothesis: Short sleep duration is related to higher risk of hypertension among children and adolescents. Methods: We conducted a cross-sectional study of 4902 children and adolescents age 5 to 18 years. Blood pressure (BP) was measured at the research center and classified using the population-based percentiles. Sleep duration and related information were determined through questionnaires. Results: The prevalence of hypertension and prehypertension were 20.3% and 15%, respectively. The median sleep duration was 8.77 ± 1.07 hours (mean ± standard deviation). A short sleep duration (<9 hours) was associated with a higher risk of hypertension when compared with the group sleeping longer (9

“…Brain activity resembling that of SWS begins to emerge in the first few months of life (Sheldon 2005b), and the proportion of SWS is greatest during childhood than in any other period in life, which reduces by approximately 40% during adolescence (Carskadon and Dement 2011), highlighting the potential importance of sleep on maturational processes and the growth of new connections. The infant sleep period of an average 17--19 hours per day gradually reduces to around 8--9 hours by adolescence (Iglowstein et al 2003, and see Figure 1 for sleep stage changes across the lifespan).…”

Sleep in Childhood and Adolescence: Age-Specific Sleep Characteristics, Common Sleep Disturbances and Associated Difficulties

Sleep changes throughout the lifespan, with particularly salient alterations occurring during the first few years of life, as well as during the transition from childhood to adolescence. Such changes are partly the result of brain maturation; complex changes in the organisation of the circadian system; as well as changes in daily routine, environmental demands and responsibilities.Despite the automaticity of sleep, given that it is governed by a host of complex mechanisms, there are times when sleep becomes disturbed. Sleep disturbances in childhood are common and may stem from behavioural difficulties or abnormalities in physiological processes and, in some cases manifest into diagnosable sleep disorders. As well as occurring exclusively, childhood sleep disturbances often co--occur with other difficulties. The purpose of this chapter is to outline the neurobiology of typical sleep/wake processes, and describe changes in sleep physiology and architecture from birth to adulthood. Furthermore, common childhood sleep disorders are described as are their associations with other traits, including all of the syndromes presented in this handbook: ASDs, ADHD, schizophrenia, and emotional/ behavioural difficulties. Throughout, we attempt to explain possible mechanisms underlying these disorders and their associations.
