Heavy episodic drinking (HED) is highly prevalent in college students. In Argentina, there is a notable lack of longitudinal studies examining drinking trajectories. The present study identified HED trajectories in Argentinean college students during the first 3 years of college (seven waves) and examined the association between risk factors for alcohol use and HED trajectories. The sample was composed of 1,240 college students [63.1% women, aged 18-25 years ( = 19.1 ± 1.7)] who completed at least three waves (the first data collection and ≥2 follow-ups). For 3 years, participants completed seven surveys that measured HED frequency, age of drinking onset, drunkenness occurrence, trait impulsivity, family history of alcohol abuse, stressful life events, and perceived peer's drinking. Latent Class Growth Analysis (LCGA) and Multinomial Logistic Regression (MLR) were used to identify the pattern and number of HED trajectories and to explore which risk factors better distinguished between the trajectories, respectively. Six HED trajectories were identified: , and . Younger age of drinking onset, alcohol intoxication, greater perception of peer drinking frequency and higher levels of impulsivity (i.e., sensation seeking, lack of premeditation, and positive urgency) increased the probability of belonging to the trajectories with more frequent HED. These trajectories partially coincide with those identified in studies from other cultures. Unlike previous studies, we did not find a trajectory with increasing/ascending HED frequency. This may be related to contextual/cultural variables unique to Argentina, like differences in the age when the peak in alcohol consumption is reached or the legal minimum age to buy alcoholic beverages in this country, and the idiosyncratic elements that characterize college life in Argentina. This work represents a step forward in the identification of risk factors differentiating between different HED trajectories, and help understand changes in alcohol use during college, in an understudied population.
重度间歇性饮酒（HED）在大学生中非常普遍。在阿根廷，明显缺乏对饮酒轨迹进行纵向研究的情况。本研究确定了阿根廷大学生在大学前三年（七次调查）期间的HED轨迹，并研究了酒精使用风险因素与HED轨迹之间的关联。样本由1240名大学生组成[63.1%为女性，年龄在18 - 25岁之间（平均年龄 = 19.1 ± 1.7）]，他们至少完成了三次调查（首次数据收集及≥2次随访）。在三年时间里，参与者完成了七项调查，这些调查测量了HED频率、饮酒开始年龄、醉酒发生率、特质冲动性、酒精滥用家族史、应激性生活事件以及对同伴饮酒的认知。分别使用潜在类别增长分析（LCGA）和多项逻辑回归（MLR）来确定HED轨迹的模式和数量，并探索哪些风险因素能更好地区分不同轨迹。确定了六种HED轨迹： ，以及 。饮酒开始年龄较小、酒精中毒、对同伴饮酒频率的更高认知以及更高水平的冲动性（即寻求刺激、缺乏预谋和积极紧迫感）增加了属于HED频率更高轨迹的可能性。这些轨迹与其他文化背景下研究中确定的轨迹部分重合。与以往研究不同的是，我们没有发现HED频率增加/上升的轨迹。这可能与阿根廷特有的背景/文化变量有关，比如该国达到酒精消费峰值的年龄差异或购买酒精饮料的法定最低年龄，以及阿根廷大学生活所特有的特质因素。这项工作在识别区分不同HED轨迹的风险因素方面向前迈进了一步，并有助于理解在一个研究较少的人群中大学期间酒精使用的变化情况。
