(1) To examine the effect of social media (SM) use on sleep quality and (2) to determine the effect of SM on competition performance among college athletes.
Cross-sectional study.
Two local Division III colleges, MA, USA.
National Collegiate Athletic Association Division III swim and track and field athletes.
Data were collected onsite through an SM use form, the lifestyle survey, and the Patient-Reported Outcomes Measurement Information System Sleep Disturbance Questionnaire. Participants were divided into 3 groups based on their SM volume: (1) less active SM users (≤2 h/d), (2) moderately active SM users (>2-≤5 h/d), and (3) active SM users (>5 h/d) for analysis.
Sleep quality and sport performance data collected through publicly available competition results. The independent variable, SM volume (hours of SM use per day over 7 days), was collected using the iPhone screen time function.
The cohort consisted of 40 male track and field athletes and 47 female track and field (37, 79%) and swimming (10, 21%) athletes. Mean SM use was 4.6 ± 3.4 h/d. The sleep quality of active SM users was worse than less active SM users ( P = 0.033). There was an independent association between increased Facebook time and poor performance after adjusting confounders (adjusted odds ratio: 0.990, 95% confidence interval: 0.981-0.999, P = 0.049).
High SM use has a negative impact on sleep quality and may hinder competition performance among college athletes. These findings may have implications for developing SM use guidelines for college athletes to improve their sleep quality and performance.
（1）研究社交媒体（SM）使用对睡眠质量的影响，（2）确定 SM 使用对大学生运动员比赛表现的影响。
横断面研究。
美国马萨诸塞州的两所地方三级学院。
美国大学生体育协会三级游泳和田径运动员。
通过 SM 使用表、生活方式调查和患者报告的结果测量信息系统睡眠障碍问卷在现场收集数据。参与者根据其 SM 量分为 3 组：（1）不活跃的 SM 用户（≤2 小时/天），（2）中度活跃的 SM 用户（>2-≤5 小时/天）和（3）活跃的 SM 用户（>5 小时/天）进行分析。
通过公开可得的比赛成绩收集睡眠质量和运动表现数据。SM 量（每天使用 SM 的小时数超过 7 天）的独立变量使用 iPhone 屏幕时间功能收集。
该队列包括 40 名男性田径运动员和 47 名女性田径（37，79%）和游泳（10，21%）运动员。平均 SM 使用量为 4.6 ± 3.4 小时/天。活跃的 SM 用户的睡眠质量比不活跃的 SM 用户差（P = 0.033）。在调整混杂因素后，Facebook 使用时间的增加与表现不佳存在独立关联（调整后的优势比：0.990，95%置信区间：0.981-0.999，P = 0.049）。
高 SM 使用量对睡眠质量有负面影响，并且可能会阻碍大学生运动员的比赛表现。这些发现可能对制定大学生运动员 SM 使用指南以提高其睡眠质量和表现有启示意义。
