Stress is a common part of college students' daily lives that may influence their physical activity (PA) and alcohol use. Understanding features of daily stress processes that predict health behaviors could help identify targets for just-in-time interventions.
This study used intensive longitudinal data to examine whether prior day stress processes predict current day PA or alcohol use.
Participants (N=58, Mage=20.5, 59% women, 70% White) were 18-to-25-year-old students who engaged in binge drinking at least twice monthly and used cannabis or tobacco in the past year. They wore activity (activPAL4) and alcohol (Secure Continuous Remote Alcohol Monitor) monitors for 11 days to assess daily PA (e.g., step counts) and alcohol use (e.g., drinking day), and completed daily surveys about yesterday's stress, including number of stressors (i.e., frequency), stressor intensity (i.e., severity), and frequency of affective states (e.g., guilt). Multilevel models examined prior day stress predicting current day PA or alcohol use.
Participants had higher odds of current day drinking (odds ratio=1.21) and greater area under the curve (B=0.08) when they experienced greater than usual stress severity the prior day. Participants had higher current day peak transdermal alcohol concentration (B=0.12) and area under the curve (B=0.11) when they more frequently experienced guilt due to stressors the prior day.
College students' unhealthy response of increasing alcohol use due to stress could adversely impact health outcomes. There is a critical need for interventions addressing students' ability to effectively manage and respond to the stress-inducing, daily demands of student life.
压力是大学生日常生活中的常见因素，可能会影响他们的体育活动（PA）和饮酒行为。了解预测健康行为的日常压力过程的特征，有助于确定即时干预的目标。
本研究使用密集的纵向数据来检验前一天的压力过程是否预测当天的 PA 或酒精使用。
参与者（N=58，平均年龄为 20.5 岁，59%为女性，70%为白人）为 18 至 25 岁的学生，他们每月至少有两次狂饮，并在过去一年中使用大麻或烟草。他们佩戴活动（activPAL4）和酒精（Secure Continuous Remote Alcohol Monitor）监测器 11 天，以评估每日 PA（例如，步数）和酒精使用（例如，饮酒日），并完成每日关于昨天压力的调查，包括压力源数量（即频率）、压力源强度（即严重程度）和情绪状态频率（例如，内疚）。多层次模型检验了前一天的压力对当天的 PA 或酒精使用的预测。
参与者在前一天经历了更大的压力严重程度时，当天饮酒的可能性更高（优势比=1.21），曲线下面积更大（B=0.08）。参与者在前一天因压力源而更频繁地经历内疚时，当天的峰值透皮酒精浓度（B=0.12）和曲线下面积（B=0.11）更高。
大学生由于压力而增加饮酒量的不健康反应可能对健康结果产生不利影响。迫切需要干预措施，以解决学生有效管理和应对学生生活中日常压力源的需求。
