Abstract

Objective

Unplanned drinking, or drinking that violates intentions to limit alcohol consumption, has been linked to significant alcohol-related consequences in college students; however, predictors and outcomes remain incompletely understood among other populations of young adults. This study identified person- and event-level predictors of unplanned drinking and explore the association of unplanned drinking with negative alcohol-related consequences in a racially and educationally diverse cohort of young adults.

Method

A total of 938 young adults (aged 18–25; 70 % female; 60 % non-college; 37 % Black) participating in a randomized trial testing text-message alcohol interventions completed ecological momentary assessments (EMA) reporting drinking intentions and alcohol consumption twice weekly for at least 4 weeks over a 14 week period. Controlling for intervention effects, mixed-effects models examined predictors of unplanned drinking days, and zero-inflated negative binomial regression models assessed the relationship between frequency of unplanned drinking and negative alcohol consequences at a 14-week follow-up.

Results

Participants reported alcohol consumption on 16.9 % of days when they had no plan to drink. Odds of unplanned drinking was higher for older age (adjusted Odds Ratio [aOR] = 1.06, p < 0.01), Black race (aOR = 1.25, p < 0.01), higher AUDIT-C score (aOR = 1.14, p < 0.001), and higher negative urgency score (aOR = 1.05, p < 0.01), weekends (aOR = 1.63, p < 0.001) and the presence of friends drinking (aOR = 9.37, p < 0.001). Compared to participants in the lowest unplanned drinking day category, those in the highest category showed a 26 % higher negative alcohol consequence rate ratio (RR = 1.26, 95 % CI [1.07, 1.48]).

Conclusions

Unplanned drinking in young adults is strongly influenced by social context and individual risk factors. This behavior, when extreme, was associated with increased negative alcohol-related consequences. Interventions targeting impulsivity and peer influence may reduce unplanned drinking and mitigate its harmful effects.

年轻人意外饮酒的预测因素和后果

在大学生中，计划外饮酒或违反饮酒限制的意图饮酒与严重的酒精相关后果有关。然而，在其他年轻人群体中，预测因素和结果仍不完全清楚。本研究确定了意外饮酒的个人和事件水平预测因素，并在种族和教育程度不同的年轻人队列中探讨了意外饮酒与酒精相关的负面后果之间的关系。方法938例青年成人(18-25岁；女性占70%；60%非大学毕业生；（37%黑人）参与了一项随机试验，测试短信酒精干预，完成了生态瞬间评估（EMA），报告饮酒意图和酒精消费量，每周两次，为期14周，至少持续4周。在控制干预效果后，混合效应模型检查了计划外饮酒天数的预测因子，零膨胀负二项回归模型评估了计划外饮酒频率与14周随访期间的负面酒精后果之间的关系。结果参与者报告说，在他们不打算喝酒的日子里，有16.9%的人饮酒。老年人意外饮酒的几率更高(调整后的优势比[aOR] = 1.06, p <；0.01)，黑人(aOR = 1.25, p <；0.01)，较高的AUDIT-C评分(aOR = 1.14, p <；0.001)，阴性紧急评分较高(aOR = 1.05, p <；0.01)，周末(aOR = 1.63, p <；0.001)和朋友饮酒的存在(aOR = 9.37, p <；0.001)。与计划外饮酒日最低类别的参与者相比，最高类别的参与者的负酒精后果率比高出26% （RR = 1.26, 95% CI[1.07, 1.48]）。结论青壮年非计划性饮酒受社会环境和个体危险因素影响较大。当这种行为极端时，与酒精相关的负面后果增加有关。针对冲动和同伴影响的干预措施可以减少计划外饮酒并减轻其有害影响。

期刊介绍： Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings. Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
