BACKGROUND
There is significant heterogeneity in alcohol and cannabis use patterns among college students, with some engaging in use patterns that heighten their risk for adverse consequences. Person-centered approaches can help identify those subgroups of students with riskier use patterns. Latent Profile Analyses (LPA) were conducted to identify subgroups based on alcohol and cannabis use frequency and quantity, to explore demographic covariates and to examine mean differences across subgroups on alcohol- and cannabis-related consequences, simultaneous use, and other substance use.
METHODS
Participants were 2,423 college students (M = 20.1; 72 % female) recruited from seven US universities who endorsed past-month alcohol and cannabis use and completed an online survey of substance use behaviors.
RESULTS
A four-profile solution was the best fitting model. Profile 1 represented "light, infrequent alcohol and cannabis use" (73.8 %), Profile 2 represented "heavy, infrequent alcohol and moderate, frequent cannabis use" (15.9 %), Profile 3 represented "moderate, frequent alcohol and cannabis use" (5.6 %) and Profile 4 represented "very heavy, frequent alcohol and heavy, frequent cannabis use" (4.7 %). Students who identify as male, White non-Hispanic, and/or Greek-affiliated were more likely to be in the heavy alcohol use profiles. Profiles 3 and 4 represent high-risk profiles, with both having a higher likelihood of simultaneous use, Profile 3 endorsing more cannabis consequences, and Profile 4 endorsing more alcohol consequences.
CONCLUSION
Results suggest that heavy alcohol or heavy co-use heightens risk for serious adverse consequences.
背景
大学生的酒精和大麻使用模式存在显著异质性，一些人采用的使用模式会增加他们遭受不良后果的风险。以个体为中心的方法可以帮助识别出那些风险更高的使用模式的学生亚组。本研究采用潜在剖面分析（LPA）根据酒精和大麻使用频率和数量对亚组进行分类，探讨人口统计学协变量，并考察亚组间在酒精和大麻相关后果、同时使用和其他物质使用方面的差异。
方法
本研究从美国的七所大学招募了 2423 名大学生（M=20.1；72%为女性），这些学生过去一个月内使用过酒精和大麻，并完成了一份关于物质使用行为的在线调查。
结果
四种模式的拟合度最好。模式 1 代表“轻度、低频的酒精和大麻使用”（73.8%），模式 2 代表“重度、低频的酒精和中度、高频的大麻使用”（15.9%），模式 3 代表“中度、高频的酒精和大麻使用”（5.6%），模式 4 代表“重度、高频的酒精和大麻使用”（4.7%）。男性、白人和/或希腊裔学生更有可能属于重度酒精使用模式。模式 3 和 4 是高风险模式，两者同时使用的可能性更高，模式 3 更有可能出现大麻相关后果，模式 4 更有可能出现酒精相关后果。
结论
研究结果表明，重度饮酒或同时大量使用酒精和大麻会增加严重不良后果的风险。
