We explored sleep patterns including morning-evening preference and their associations with other lifestyle determinants among high school students.
We conducted a cross-sectional survey of students grades 9-12 from a private high school in the United States. One hundred and thirty-one students completed an online survey comprising 23 original, investigator-created questions, a mood scale, the Pittsburgh Sleep Quality Index (PSQI), and the Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ).
We found that 80% of students reported a sleep deficit. As defined by the PSQI, 69% of girls and 58% of boys in this sample were poor sleepers. Eveningness was a strong predictor of poor sleep, particularly among students aged 15 years (odds ratio [OR] 9.92; 95% confidence interval [CI], 1.52-64.8), among whom poor sleep quality was also associated with a higher body mass index (BMI) (OR, 6.97; 95% CI, 1.01-48.2).
Our pilot study suggests that morningness-eveningness is a strong predictor of sleep quality among high school students.
我们探讨了高中生的睡眠模式，包括晨型-夜型偏好及其与其他生活方式决定因素的关联。
我们对美国一所私立高中9至12年级的学生进行了横断面调查。131名学生完成了一项在线调查，该调查包括23个由研究者原创的问题、一个情绪量表、匹兹堡睡眠质量指数（PSQI）以及霍恩-奥斯特伯格晨型-夜型问卷（MEQ）。
我们发现80%的学生报告存在睡眠不足。根据PSQI的定义，该样本中69%的女生和58%的男生睡眠质量较差。夜型是睡眠质量差的一个强预测因素，尤其是在15岁的学生中（优势比[OR]为9.92；95%置信区间[CI]，1.52 - 64.8），在这些学生中，睡眠质量差还与较高的体重指数（BMI）相关（OR，6.97；95% CI，1.01 - 48.2）。
我们的初步研究表明，晨型-夜型是高中生睡眠质量的一个强预测因素。
