To inform public health recommendations for adolescent sleep, the amounts of sleep associated with the highest levels of academic achievement and mental health were examined. The degree to which daily variability in sleep duration represents an underappreciated but functionally significant sleep behavior also was tested. A total of 421 adolescents (M = 15.03 years) with Mexican-American backgrounds reported nightly sleep times for 2 weeks; approximately 80% repeated the same protocol 1 year later. Multilevel modeling indicated that the amount of sleep associated with the lowest levels of internalizing and externalizing symptoms was more than 1 hr greater than the amount associated with the highest levels of academic performance. Greater daily variability in sleep duration predicted greater symptomatology and mixed academic outcomes.
为了为青少年睡眠制定公共卫生建议,研究了与最高学术成就和心理健康水平相关的睡眠量。还测试了睡眠持续时间的日常可变性在多大程度上代表了一种被低估但功能上重要的睡眠行为。共有 421 名具有墨西哥裔美国人背景的青少年(M=15.03 岁)报告了两周内的每晚睡眠时间;大约 80%的人在 1 年后重复了相同的方案。多层次建模表明,与最高学术表现相关的睡眠量比与最低内化和外化症状相关的睡眠量多 1 小时以上。睡眠持续时间的日常可变性越大,预示着症状和混合的学术成果越多。
