背景：预防和干预青少年物质使用是公共卫生的优先事项。大多数青少年将使用某种形式的药物，相当多的少数人将过渡到使用多种药物。一个新兴的研究机构采取了以人为本的方法来模拟青少年物质使用随着时间的推移;然而，研究结果是模棱两可的。我们的研究建模青少年物质使用过渡模式超过三年的基础上，一个全面的列表的物质和检查性别作为moderator.Methods：我们使用了三个年度波的数据（时间2，时间3，时间4）从一个正在进行的纵向研究的种族多样性的样本1042青少年最初招募多个高中在得克萨斯州东南部。参与者中56%为女性，32%为西班牙裔，30%为白人，29%为非洲裔美国人，9%为其他人，时间2时平均年龄为16.1岁（SD = 0.79）。数据进行了分析，使用潜在的过渡analysis.Results：该研究确定了三种物质的使用状态（轻度酒精使用，酒精和适度maritime使用，和多物质使用），并建议青少年一般保持在相同的状态随着时间的推移。当他们确实过渡时，通常会进入更有害的物质使用状态。此外，男性比女性更有可能是多种物质的用户，并有更高的概率过渡到和留在一个更有害的药物使用status.Conclusions：该研究确定了整体和性别特定的青少年物质使用的过渡模式，这是至关重要的通知干预发展。
Background: The prevention and intervention of adolescent substance use is a public health priority. Most adolescents will engage in some form of substance use, and a sizeable minority will transition to using multiple substances. An emerging body of research takes a person-centered approach to model adolescent substance use over time; however, the findings have been equivocal. Our study modeled adolescent substance use transition patterns over three years based on a comprehensive list of substances and examined gender as a moderator.Methods: We used three annual waves of data (Time 2, Time 3, and Time 4) from an ongoing longitudinal study of an ethnically diverse sample of 1042 adolescents originally recruited from multiple high schools in southeast Texas. Participants were 56% female, 32% Hispanics, 30% Whites, 29% African Americans, and 9% other with an average of 16.1 years (SD = 0.79) at Time 2. Data were analyzed using latent transition analyses.Results: The study identified three substance use statuses (Mild Alcohol Use, Alcohol and Moderate Marijuana Use, and Polysubstance Use) and suggested that adolescents generally remained in the same statuses over time. When they did transition, it was typically to a more harmful substance use status. Further, males were more likely than females to be polysubstance users and had higher probabilities of transiting to and remaining in a more harmful drug use status.Conclusions: The study identifies overall and gender specific adolescent substance use transition patterns, which are vital to informing intervention development.
