The objective was to investigate screen time (ST) and objectively measured sleep quality in college students. Participants were undergraduate students attending a large metropolitan public university in the southeastern U.S. Participants wore accelerometers on their wrist for 24hr/day for 14 days to capture sleep outcomes, and completed a survey reporting ST duration. Analyses explored weight-status, race/ethnicity, and sleep patterns (presence of daytime sleep) differences among students. Participants (n=29, 86% female, ~21.5 years old, 38% White, 35% Overweight/Obese) slept for an average of 433.8 minutes/night, reported 419.1 minutes of daily ST, and 112 minutes of ST after 10:00PM. College students with daytime sleep (i.e., napping) reported approximately -92 minutes less of daily ST than peers (p=0.04; effect size=0.86). Further studies in larger, diverse samples are needed to explore ST and sleep, specifically the causal relationship and its potential to impact the health of college students at greatest risk of poor health outcomes.
目的是调查大学生的屏幕使用时间（ST）和客观测量的睡眠质量。参与者是就读于美国东南部一所大型都市公立大学的本科生。参与者连续14天每天24小时佩戴手腕加速度计以获取睡眠结果，并完成一份报告ST持续时间的调查问卷。分析探讨了学生之间的体重状况、种族/族裔和睡眠模式（白天是否午睡）差异。参与者（n = 29，86%为女性，约21.5岁，38%为白人，35%超重/肥胖）平均每晚睡眠433.8分钟，报告每日ST时间为419.1分钟，晚上10点后ST时间为112分钟。有白天睡眠（即午睡）的大学生报告的每日ST时间比同龄人少约92分钟（p = 0.04；效应大小 = 0.86）。需要在更大、更多样化的样本中进行进一步研究，以探索ST与睡眠，特别是因果关系及其对健康结果风险最大的大学生健康的潜在影响。
