Young adults report the heaviest drinking of any age group, and many are at risk for experiencing an alcohol use disorder. Most research investigating young adult drinking has focused on single indicators of use. Using multiple dimensions of consumption, such as federal guidelines for daily/weekly drinking and engagement in drinking at twice the binge threshold ("high-intensity drinking") to characterize drinking behavior could illuminate drinking patterns linked with harms.
We used a person-centered approach to examine latent classes of drinkers from a national sample of young adults. Further, we compared classes on college status.
We used 2012-2013 data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC)-III. We included past-year drinkers aged 18-22 years (n = 2213). Latent classes were estimated based on drinking frequency, daily/weekly drinking, frequency of heavy episodic drinking (4+/5+ drinks for women/men), frequency of high-intensity drinking (8+/10+ drinks), and intoxication frequency.
Five latent classes were identified: Occasional, Light Drinkers (30%), Regular Drinkers (6%), Infrequent Drinkers with Occasional Binging (10%), Frequent Drinkers with Occasional Binging (22%), and High-Intensity Drinkers (32%). Although membership in the two riskiest classes were more common among college-attenders, odds of being a High-Intensity Drinker relative to the second riskiest class was not significantly different for college- and non-college-attending young adults. Conclusions/Importance: As high-intensity drinking does not appear to be a drinking pattern unique to college-attenders and non-college-attenders are less likely to mature out of heavy drinking patterns, intervention efforts are needed for this at-risk age group.
年轻人的饮酒量在所有年龄段中最高,许多人有出现酒精使用障碍的风险。大多数研究年轻人饮酒问题的研究都集中在单一的使用指标上。使用消费的多个维度,如联邦关于每日/每周饮酒的指南和达到两倍 binge 阈值(“高强度饮酒”)的饮酒频率来描述饮酒行为,可以阐明与危害相关的饮酒模式。
我们使用一种以人为中心的方法,从全国范围内的年轻成年人样本中检查潜在的饮酒者群体。此外,我们比较了不同饮酒群体的大学生身份。
我们使用了 2012-2013 年国家酒精相关状况调查(NESARC-III)的数据。我们纳入了过去一年饮酒的 18-22 岁人群(n=2213)。基于饮酒频率、每日/每周饮酒量、重度饮酒发作频率(女性/男性为 4+/5+ 杯)、高强度饮酒频率(女性/男性为 8+/10+ 杯)和醉酒频率,估计潜在的饮酒群体。
确定了五个潜在的饮酒群体:偶尔饮酒者(30%)、轻度饮酒者(6%)、偶尔 binge 饮酒者(10%)、经常 binge 饮酒者(22%)和高强度饮酒者(32%)。尽管参加大学的人群中,属于两个风险最高群体的比例更高,但与第二高风险群体相比,参加大学和未参加大学的年轻人成为高强度饮酒者的几率并没有显著差异。结论/意义:由于高强度饮酒似乎不是参加大学者特有的饮酒模式,而且未参加大学者不太可能摆脱重度饮酒模式,因此需要针对这个高危年龄段采取干预措施。
