To examine the associations between objective measures of sleep during the school week and academic achievement in mathematics and languages in typically developing adolescent girls.
Eighty adolescent girls aged 12-17 years (M=14.74, SD=1.3) participated. For five consecutive weeknights, sleep was assessed in the home environment using an actigraph. Academic achievement was assessed using report card grades.
Girls who obtained on average less sleep than the recommended amount of 8 to 10 hrs per night had significantly lower grades in mathematics compared to girls who obtained the recommended amount (77.61 vs 86.16, respectively; η =0.11). Hierarchical regression analyses adjusted for age, pubertal status, and socioeconomic status revealed that longer average sleep time was significantly associated with higher grades in mathematics (=4.78, 95% CI [2.03,7.53]). No significant associations were found between sleep variables and grades in languages.
Longer average weekday sleep duration is associated with academic achievement of adolescent girls in mathematics.
研究上学期间睡眠的客观指标与发育正常的青春期女孩数学和语言学习成绩之间的关联。
80名12至17岁的青春期女孩（平均年龄M = 14.74，标准差SD = 1.3）参与了研究。连续五个工作日的夜晚，使用活动记录仪在家庭环境中评估睡眠情况。使用成绩单成绩评估学业成绩。
与每晚睡眠达到推荐量8至10小时的女孩相比，平均睡眠少于推荐量的女孩数学成绩显著更低（分别为77.61和86.16；η = 0.11）。在对年龄、青春期状态和社会经济地位进行调整的分层回归分析中发现，平均睡眠时间越长与数学成绩越高显著相关（β = 4.78，95%置信区间[2.03, 7.53]）。未发现睡眠变量与语言成绩之间存在显著关联。
上学日平均睡眠时间较长与青春期女孩的数学学业成绩相关。
