睡眠问题在青少年时期很常见，并且会对青少年的情绪产生负面影响。到目前为止，研究睡眠延长对青少年睡眠和抑郁症状的影响仍然缺乏。本研究旨在探讨逐步延长睡眠时间结合睡眠卫生建议对青少年慢性睡眠减少的影响，客观测量睡眠，自我报告的睡眠问题和抑郁症状。参与者被随机分配到睡眠延长组（通过提前晚上就寝时间并接受睡眠卫生建议来逐步延长睡眠）或对照组（没有指导）。在三周内用活动记录仪测量睡眠，第一周是基线周，最后两周是延长睡眠的实验周。其他结果变量是自我报告的睡眠问题（白天嗜睡，失眠和昼夜节律睡眠障碍的症状）和抑郁症状，这是之前和之后的实验manipulation.ResultsDuring的第三周的实验，在睡眠延长组的青少年有较早的就寝时间，较早的睡眠发作，花更多的时间在床上，比对照组的青少年睡眠时间更长。他们的慢性睡眠减少，失眠症状和抑郁症状明显减轻。此外，有改善昼夜节律睡眠障碍症状和睡眠quality.ConclusionGradually睡眠延长结合睡眠卫生咨询的趋势似乎有有益的影响睡眠，自我报告的睡眠问题和抑郁症状的青少年慢性睡眠减少。虽然我们无法区分睡眠延长和睡眠卫生建议的影响，但结果表明，提前就寝时间可以延长睡眠时间并改善抑郁症状。
ObjectiveSleep problems are common and persistent during adolescence and can have negative effects on adolescents' mood. To date, studies that investigate the effects of sleep extension on adolescents' sleep and depressive symptoms are still lacking. This study aims to investigate the effects of gradual sleep extension combined with sleep hygiene advice in adolescents with chronic sleep reduction on objectively measured sleep, self‐reported sleep problems and depressive symptoms.MethodsFifty‐five adolescents with chronic sleep reduction (mean age: 15.44 years; 85.5% females) were included in the study. Participants were randomly assigned to either a sleep extension group (gradual sleep extension by advancing bedtimes in the evening and receiving sleep hygiene advice) or to a control group (no instruction). Sleep was measured with actigraphy during three weeks, the first week was the baseline week, and the last two weeks were the experimental weeks during which sleep was extended. Other outcome variables were self‐reported sleep problems (daytime sleepiness, symptoms of insomnia and circadian rhythm sleep disorder) and depressive symptoms, which were assessed before and after the experimental manipulation.ResultsDuring the third week of the experiment, adolescents in the sleep extension group had earlier bedtimes, earlier sleep onsets, spent more time in bed and slept longer than adolescents in the control group. Their chronic sleep reduction, insomnia symptoms and depressive symptoms diminished significantly. In addition, there was a trend of improved circadian rhythm sleep disorder symptoms and sleep quality.ConclusionGradual sleep extension combined with sleep hygiene advice seems to have beneficial effects on sleep, self‐reported sleep problems and depressive symptoms of adolescents with chronic sleep reduction. Although we cannot distinguish between the effects of sleep extension and sleep hygiene advice, the results suggest that advancing bedtimes can extend sleep and improve depressive symptoms.
