“…Sleeping difficulties are recognized as an international public health issue ( American Academy of Pediatrics, 2014 ; Chattu et al., 2018 ; Gradisar et al, 2011 ; Louzada, 2019 ). Research shows that 39–73% of adolescents get insufficient sleep night after night ( Alves et al, 2020 ; Galland et al, 2020 ; Jakobsson et al, 2019 ; Twenge et al, 2017 ; Wheaton et al, 2018 ). The recommended 8–10 hr of sleep per night is essential for health, well-being, and education ( Hirshkowitz et al, 2015 ).…”

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.

“…As such, this may lead to some subscales (i.e., sleep-disordered breathing) and their subsequent associations with BP values to be underrepresented as a function of the instrument. Considering previous literature and these subscale data from the present study, daytime sleepiness and parasomnias may be particular domains of multidimensional sleep that, if targeted, could mitigate elevations in childhood BP beyond recommendations to simply extend sleep duration in this population (Alves et al, 2020).…”

Summary Shortened and poor‐quality sleep have emerged as non‐traditional risk factors for the development of hypertension in adults, and it is likely these relations extend to paediatric populations when evaluating sleep subjectively. Therefore, we aimed to evaluate subjective sleep metrics and their associations with central and peripheral blood pressure (BP) values in children. We hypothesized that poor‐quality sleep and short sleep duration would be associated with elevated pressures in healthy children. Subjective sleep habits and sleep duration were evaluated using the Children's Sleep Habits Questionnaire (CSHQ) in 29 children aged 7–12 years (13 male/16 female). A total sleep score was generated by summing subscale scores: a higher score indicates poorer sleep habits. Peripheral BP was measured, and central pressures were estimated using pulse wave analysis. Pearson's r correlations were used to assess relations between total sleep score, sleep duration, and sleep score subscales with BP values. Sleep score was positively associated with central and peripheral systolic pressure (r = 0.43, p = 0.02 and r = 0.41, p = 0.03, respectively), diastolic pressure (r = 0.42, p = 0.02 and r = 0.36, p = 0.05, respectively) and mean arterial pressure (r = 0.40, p = 0.03 and r = 0.36, p = 0.03, respectively). Sleep duration was negatively associated with central and peripheral diastolic pressure (r = −0.40, p = 0.03 and r = −0.41, p = 0.03, respectively). Regarding the CSHQ subscales, daytime sleepiness and parasomnias were consistently positively associated with BP values. These findings support sleep as a primordial prevention target for hypertension and the maintenance of cardiovascular health during childhood. Consideration of a variety of sleep habits using tools such as the CSHQ may provide important insights into early‐life cardiovascular risk.

“…Em conclusão, os autores propõem que as aulas não tenham início antes das 8h30 para adolescentes brasileiros que estão cursando o ensino médio 40 . Porém, trata-se de uma medida de difícil implementação, considerando os sistemas educacionais e a necessidade de alteração não somente dos horários dos estudantes, mas de toda a comunidade escolar, inclusive dos pais 3,21 .…”

“…Estudos anteriores realizados com adolescentes indicaram que atrasar o horário de início da escola pode resultar em benefícios sustentados na duração do sono, no estado de alerta diurno e nos problemas mentais 18,19 . No Brasil, o formato de operação da escola tem sido tradicionalmente organizado em três turnos, com turnos da manhã e da tarde, e para adolescentes de 15 anos ou mais, particularmente aqueles que trabalham durante o dia, geralmente é possível frequentar a escola à noite 20,21 . Mais recentemente, várias escolas adotaram o sistema de tempo integral, com o objetivo explícito de aumentar a exposição acadêmica, os programas extracurriculares e a qualidade da educação 22 .…”

RESUMO Objetivo Investigar a prevalência de sonolência diurna excessiva (SDE) e os fatores associados em adolescentes de escolas militares. Métodos Participaram 466 adolescentes do ensino médio (15 a 17 anos) de ambos os sexos (230 homens). Os participantes foram entrevistados sobre as características sociodemográficas e sobre a duração de sono (semana e final de semana), adotando-se valores < 8 horas de sono como tempo insuficiente de sono. A SDE foi avaliada com a escala de sonolência de Epworth, na qual os adolescentes que obtivessem escores ≥ 10 apresentavam SDE. Resultados A prevalência geral de SDE foi de 34,1%. A média de horas de sono foi de 6,9 h (±1,85) em dias da semana e de 8,5 h (±1,96) nos fins de semana. Identificou-se que 60% dos adolescentes apresentaram baixa duração do sono semanal (p = 0,05). Observaram-se, no modelo final de regressão, maiores riscos de SDE nos indivíduos com baixa duração de sono (OR: 1,55; IC de 95%: 1,04-2,31) e que utilizavam o celular antes de dormir (OR: 4,30; IC de 95%: 2,00-9,23). Conclusão A SDE foi fortemente associada ao uso de celular antes de dormir. Outros fatores associados são sono insuficiente e estudar em tempo integral. Medidas educacionais, administrativas e de saúde são necessárias para melhorar o sono em adolescentes.
