“…72 Young children's poorer language function was positively associated with shorter sleep hours during the night. 73 For preschoolers (4 years) and school-aged children (10 years), short sleep duration (< 11 hours) was negatively associated with receptive vocabulary. 74 Poor emotional regulation and reactivity have been associated with short sleep duration (30-36 month-olds, 55 18-month-olds 47 for < 13 hours, and 2.5-6 year-olds for < 10 hours 57 ), but one study reported a U-shape relationship.…”

Insufficient sleep produces various brain dysfunctions in both adults and children, and is associated with behavioral, cognitive and physical problems, as well as with atypical early development. Insufficient sleep has also been reported to cause obesity. Insufficient sleep-induced obesity is often associated with the occurrence of metabolic syndrome. More effort is needed to ensure that children are receiving sufficient sleep.

Background Sleep affects a wide array of health outcomes and is associated with the quality of life. Among students, sleep quality is affected by school stage and grade; however, data regarding the different sleep-related problems students experience at different school stages are limited. In this study, we aimed to explore sleep quality among a student sample ranging from elementary school to university level. Methods Overall, data were examined for 9392 subjects aged 9–22 years. Information on sociodemographic characteristics and other variables were collected through self-administered questionnaires. Sleep quality on school nights was evaluated using the standard Pittsburgh Sleep Quality Index; global score >5 was classified as poor sleep quality. For the high school sample, logistic regression analysis was used to estimate associations between sleep quality and certain factors. Results Of the elementary school, middle school, vocational high school, senior high school, and university students, 7.5%, 19.2%, 28.6%, 41.9%, and 28.5%, respectively, showed poor sleep quality. The high school students reported the highest prevalence of shorter sleep duration (70.8%), day dysfunction (84.7%), and subjective poor sleep quality (17.2%). The elementary school students showed the highest prevalence of poor sleep efficiency (17.9%). The university students showed the highest prevalence of sleep medication use (6.4%). The vocational high school students reported the highest prevalence of sleep latency (6.3%) and sleep disturbance (7.4%). Logistic regression modeling indicated that sleep quality is positively associated with school stage, grade, family atmosphere, academic pressure, and number of friends. Conclusion Sleep quality and sleep features change greatly from elementary school to university. Interventions to improve sleep quality should consider targeting the specific issues students experience at each school stage. Alarmed by the high prevalence of poor sleep quality among high school students, it is recommended that high school students should be informed of their sleep matter and the consequences.

Influence of sleep-onset time on the development of 18-month-old infants: Japan Children’s cohort study

Abstract: Although our results may be confounded by sleep problems resulting from pre-existing developmental disabilities, we can safely conclude that appropriate sleeping habits are important for healthy development in 18-month-old infants.
