We examined alcohol and marijuana use trajectories among Latino adolescents in the San Francisco Bay Area.
A total of 410 Latino adolescents aged 14-19 years were recruited from community venues from years 2001 to 2004 and followed up for 2 years. In separate models, we identified groups with similar temporal patterns of alcohol and marijuana use using semi-parametric latent group trajectory modeling. Multivariable multinomial logistic regression was used to identify factors associated with the probability of trajectory group membership.
The use of alcohol (76%) and marijuana (55%) in the previous 6 months was common. Three alcohol-use trajectories were identified: low users (18%), moderate users (37%), and frequent users (45%). Low alcohol users (vs. moderate users) were found to be younger in age, preferred Spanish language, and had more parental monitoring. Frequent users were more likely to be male, sexually active, gang exposed, and have less parental monitoring than moderate users. Similarly, three marijuana-use trajectories were identified: low users (36%), moderate users (35%), and frequent users (28%), with similar correlates of group membership.
Urban Latino adolescents' substance use is shaped by complex cultural and environmental influences. Patterns of substance use emerge by early adolescence highlighting the need for timely intervention.
我们研究了旧金山湾区拉丁裔青少年的酒精和大麻使用轨迹。
2001 年至 2004 年期间，我们从社区场所招募了 410 名年龄在 14 至 19 岁的拉丁裔青少年，并对他们进行了为期 2 年的随访。在单独的模型中，我们使用半参数潜在群组轨迹建模来识别具有相似酒精和大麻使用时间模式的群组。多变量多项逻辑回归用于确定与轨迹组归属概率相关的因素。
在过去 6 个月中，经常使用酒精（76%）和大麻（55%）的情况很常见。确定了三种酒精使用轨迹：低使用者（18%）、中度使用者（37%）和频繁使用者（45%）。与中度使用者相比，低酒精使用者年龄较小，更喜欢西班牙语，并且受到更多的父母监督。与中度使用者相比，频繁使用者更可能是男性、性活跃、接触帮派、受到的父母监督较少。同样，确定了三种大麻使用轨迹：低使用者（36%）、中度使用者（35%）和频繁使用者（28%），具有相似的群体归属相关性。
城市拉丁裔青少年的物质使用受到复杂的文化和环境影响的影响。物质使用模式在青少年早期出现，强调需要及时干预。
