Sleep disorders are very common among teenagers. One of possible reasons is a discrepancy between social and biological activity of children. It is known that adolescents with a late chronotype (e.g., a later midpoint of sleep) have a lowered academic achievement. The aim of our study was to evaluate sleep quality and other sleep-wake characteristics in relation to academic scores self-reported by teenagers living in urban and rural areas of Republic of Karelia.
Five hundred respondents, aged 10-17 years, participated in a questionnaire survey of chronotype and sleep quality. The Munich chronotype questionnaire (MCTQ) and the Pittsburgh Sleep Quality Index (PSQI) were used. Sleep duration during week and weekend, sleep quality and hygiene were assessed.
A decrease in sleep duration in adolescents, aged 10-18 years, was observed. A larger social jetlag was significantly higher in girls compared to boys. Gender had a significant impact on sleep quality. More than 10% of the total variation in academic achievement of Karelian teenagers can be explained by the difference in their gender and average sleep duration.
睡眠障碍在青少年中非常普遍。一个可能的原因是儿童的社交和生物活动之间存在差异。众所周知，晚睡型青少年（例如，睡眠中点较晚）的学业成绩较低。我们研究的目的是评估卡累利阿共和国城乡青少年自我报告的学业成绩与睡眠质量及其他睡眠-觉醒特征之间的关系。
500名年龄在10至17岁之间的受访者参与了关于昼夜节律类型和睡眠质量的问卷调查。使用了慕尼黑昼夜节律类型问卷（MCTQ）和匹兹堡睡眠质量指数（PSQI）。评估了工作日和周末的睡眠时间、睡眠质量和睡眠卫生情况。
观察到10至18岁青少年的睡眠时间减少。女孩的社会时差比男孩明显更大。性别对睡眠质量有显著影响。卡累利阿青少年学业成绩总变异的10%以上可由其性别和平均睡眠时间的差异来解释。
