Emerging adults, particularly university students, who are physically active, drink more than their less physically active peers. We extended this between-person relationship to the within-person level of analysis, by examining whether students are more likely to drink on days when they exercise, and whether this within-person association remains after controlling for potential confounding factors. We also explored the temporal sequence of the physical activity (PA)-alcohol use association. University students ( = 426) completed a 30-day online diary. The small positive within-person association between PA and alcohol use was not retained after controlling for day of the week. However, previous day's drinking was inversely associated with next day's PA on weekdays. These findings suggest that the previously reported positive PA-alcohol association does not necessarily align with the within-person daily association. Future studies with more nuanced measurement strategies, such as ecological momentary assessment, are needed to better understand the association between PA and alcohol use.
处于成年初期的人，尤其是大学生，那些身体活跃的人比身体活动较少的同龄人饮酒量更多。我们通过研究学生在锻炼的日子里是否更有可能饮酒，以及在控制潜在混杂因素后这种个体内部关联是否仍然存在，将这种个体间关系扩展到个体内部层面的分析。我们还探讨了身体活动（PA）与酒精使用关联的时间顺序。大学生（n = 426）完成了一份为期30天的在线日记。在控制了星期几之后，PA与酒精使用之间个体内部的小的正相关关系不再存在。然而，在工作日，前一天的饮酒与第二天的PA呈负相关。这些发现表明，先前报道的PA与酒精的正相关关系不一定与个体内部的日常关联一致。需要未来采用更细致的测量策略（如生态瞬时评估）的研究，以更好地理解PA与酒精使用之间的关联。
