项目摘要

Project Summary/Abstract Drinking use behaviors occur within a social-ecological environment where individuals are influenced by personal, interpersonal, community, societal and political factors. Adolescence is a developmentally sensitive time period where such factors may influence how frequently and consistently individuals use alcohol. While drinking patterns for young people in the US tend to be typified by escalating frequency of consumption with age, up until a decrease in use starting in the mid- to late-20s, drinking patterns across these ages are more heterogeneous than the group average would suggest. Instead, subgroups of individuals may follow a subset of drinking patterns with variations in the timing of drinking initiation, frequency of consumption, and binge drinking behaviors. While prior research has documented heterogeneous drinking trajectories within samples of young people in the US, no literature has modeled parallel trajectory groups incorporating both drinking frequency and binge drinking simultaneously. Fewer have modeled how adolescent exposures and experiences may influence trajectory membership. The proposed study advances our current understanding of alcohol use trajectories by modeling parallel trajectories of alcohol use as well as binge drinking behaviors. For aim 1, we will use dual trajectory Latent Growth Mixture Modeling (LGMM) to identify and describe trajectories of alcohol use and binge drinking from age 15 through 40 in a nationally representative sample of US adolescents followed longitudinally into adulthood. In aim 2, we will use multinomial regression approaches to investigate the independent and interactive influences of familial and environmental factors experienced in adolescence on the identified individual alcohol use trajectories. A deeper understanding of long-term alcohol use patterns and their influences into adulthood may inform future harm reduction messaging and programming. In addition, examining dual (sometimes referred to as parallel process) trajectories between frequency of drinking overall and binge drinking will help identify variations in drinking behaviors that may be masked when looking at only one behavioral outcome in isolation.

项目概要/摘要饮酒行为发生在社会生态环境中，个人受到以下因素的影响：个人、人际、社区、社会和政治因素。青春期是一个发育敏感期这些因素可能影响个人饮酒的频率和持续性的时间段。尽管美国年轻人的饮酒模式往往表现为消费频率不断增加年龄，直到从 20 多岁中后期开始减少饮酒，这些年龄段的饮酒模式更多异质性高于群体平均水平。相反，个体子群可能会遵循一个子集饮酒模式的变化，包括开始饮酒的时间、饮酒的频率和暴饮暴食的情况饮酒行为。虽然之前的研究已经记录了样本中的异质饮酒轨迹对于美国年轻人来说，没有文献对包含饮酒的平行轨迹群体进行建模频率和同时酗酒。很少有人模拟青少年如何接触和经验可能会影响轨迹成员资格。拟议的研究增进了我们目前对通过对酒精使用和酗酒行为的平行轨迹进行建模来研究酒精使用轨迹。为了目标 1，我们将使用双轨迹潜在生长混合模型（LGMM）来识别和描述轨迹美国全国代表性样本中 15 岁至 40 岁的饮酒和酗酒情况青少年纵向进入成年期。在目标 2 中，我们将使用多项回归方法研究家庭和环境因素的独立和交互影响青少年时期已确定的个人饮酒轨迹。对长期酗酒有更深入的了解使用模式及其对成年期的影响可能会为未来减少伤害的信息传递提供信息编程。此外，检查之间的双重（有时称为并行过程）轨迹总体饮酒频率和酗酒频率将有助于识别饮酒行为的变化，这些变化可能会导致当仅孤立地看待一种行为结果时，这一点就被掩盖了。
