Conduct problems, substance use, and risky sexual behavior have been shown to coexist among adolescents, which may lead to significant health problems. The current study was designed to examine relations among these problem behaviors in a community sample of children at high risk for conduct disorder. A latent growth model of childhood conduct problems showed a decreasing trend from grades K to 5. During adolescence, four concurrent conduct problem and substance use trajectory classes were identified (high conduct problems and high substance use, increasing conduct problems and increasing substance use, minimal conduct problems and increasing substance use, and minimal conduct problems and minimal substance use) using a parallel process growth mixture model. Across all substances (tobacco, binge drinking, and marijuana use), higher levels of childhood conduct problems during kindergarten predicted a greater probability of classification into more problematic adolescent trajectory classes relative to less problematic classes. For tobacco and binge drinking models, increases in childhood conduct problems over time also predicted a greater probability of classification into more problematic classes. For all models, individuals classified into more problematic classes showed higher proportions of early sexual intercourse, infrequent condom use, receiving money for sexual services, and ever contracting an STD. Specifically, tobacco use and binge drinking during early adolescence predicted higher levels of sexual risk taking into late adolescence. Results highlight the importance of studying the conjoint relations among conduct problems, substance use, and risky sexual behavior in a unified model.
行为问题、物质使用和危险性行为在青少年中普遍存在，可能导致严重的健康问题。本研究旨在检验高风险品行障碍儿童的社区样本中这些问题行为之间的关系。童年品行问题的潜在增长模型显示，从 K 年级到 5 年级呈下降趋势。在青春期，使用并行过程增长混合模型确定了四个同时存在的品行问题和物质使用轨迹类别（高品行问题和高物质使用、品行问题增加和物质使用增加、品行问题最小和物质使用增加以及品行问题最小和物质使用最小）。对于所有物质（烟草、狂饮和大麻使用），幼儿园时期较高的儿童品行问题水平预示着与较不严重的类别相比，更有可能被归类为更严重的青少年轨迹类别。对于烟草和狂饮模型，随着时间的推移，儿童品行问题的增加也预示着更有可能被归类为更严重的类别。对于所有模型，被归类为更严重类别的个体表现出更高比例的早期性行为、不经常使用避孕套、为性服务获得金钱以及曾经感染性传播疾病。具体来说，青少年早期的烟草使用和狂饮预示着后期青少年时期更高水平的性冒险行为。结果强调了在统一模型中研究品行问题、物质使用和危险性行为的共同关系的重要性。
