本研究探讨了刚进入大学一年级的高中毕业生的昼夜节律偏好和咖啡因摄入与学业成绩和学习时间之间的关系。美国 90 所学士学位级别院校的一年级大学生被邀请完成学生参与度大学入学调查 (BCSSE) 和早晨综合量表 (CSM)，并回答有关咖啡因摄入量的问题。 2013 年夏季，对每个校园进行了调查。这项研究仅包括 2013 年春季从美国高中毕业的学生。本研究的最终样本包括 25,200 名完成 BCSSE、CSM 和有关咖啡因消耗问题的学生。与中等或早间型（M 型）相比，夜间型（E 型）在高中获得 A/A-aEuro (TM) 的可能性显着较低，每周学习 16 小时或以上的可能性也较低（p < 0.05）。总体而言，一年级学生平均每天摄入 1.1 份咖啡因，其中 39% 的学生表示没有摄入咖啡因。与同样表明每日不摄入咖啡因的 E 型人群 (31%) 相比，M 型人群更有可能不摄入咖啡因 (54%) (p < 0.05)。然而，与摄入相同量的 M 型人 (7%) 相比，E 型人每天摄入三份或更多咖啡因的可能性 (18%) 大约高 2.5 倍 (p < 0.05)。不摄入咖啡因的 M 型人成绩最高，近 64% 的人表示他们在高中时大部分成绩为 A 或 A-。然而，一旦每天摄入三份或更多咖啡因，早起型人相对于晚间型人在高中成绩方面的明显优势就会完全改善。这项研究为教育工作者和健康专业人员提供了更多信息，以制定计划并提供资源，帮助青少年更好地了解睡眠行为和咖啡因使用对其学业成绩的影响。
This study examines the relationships between circadian preference and caffeine use with academic performance and hours spent studying for recent high school graduates entering their first year of college.Entering first-year college students enrolled at 90 baccalaureate-level institutions across the USA were invited to complete the Beginning College Survey of Student Engagement (BCSSE) and the Composite Scale of Morningness (CSM) as well as answer questions regarding caffeine consumption. Surveys were administered on each campus during the summer months of 2013. Only those that graduated from a US high school in the spring of 2013 were included in this study. The final sample for this study included 25,200 students that completed the BCSSE, CSM, and questions regarding caffeine consumption.Evening types (E-types) were significantly less likely to report earning A/A-aEuro (TM) s in high school and less likely to study 16 or more hours per week compared to intermediate or morning types (M-types) (p < 0.05). Overall, entering first-year students reported an average of 1.1 servings of caffeine per day, with 39 % reporting no caffeine consumption. M-types were more likely to consume no caffeine (54 %) compared to E-types that also indicated no daily caffeine (31 %) (p < 0.05). However, E-types were approximately 2.5 times more likely to consume three or more daily servings of caffeine (18 %) compared to M-types that consume the same amount (7 %) (p < 0.05). M-types that consumed no caffeine reported the highest grades with nearly 64 % reporting they earned mostly A's or A-'s in high school. However, the apparent advantage that morning types had over evening types regarding high school grades was completely ameliorated once three or more servings of caffeine were consumed per day.This study provides additional information to educators and health professionals to create programs and provide resource to help adolescents better understand the impact of their sleep behaviors and use of caffeine on their academic performance.
