关于下丘脑-垂体-肾上腺 (HPA) 功能(以皮质醇为索引)与物质使用之间的关联机制有许多理论。然而,同时促进 HPA 功能和物质使用的基因混淆这种关联(例如遗传混杂)的可能性在很大程度上被忽视了。我们探索了遗传学在皮质醇与物质使用关联中的潜在作用,建立了一个概念框架,将皮质醇和物质使用如何与发育进程相关的理论和机制置于其中,并根据我们的发现提出了新的假设。我们的结论是,皮质醇功能与物质使用之间的关系很复杂,发生在多个分析层面,并且在物质使用进展的多个阶段是双向的。此外,皮质醇与物质使用关联中可能存在遗传混杂,因此需要遗传信息设计来研究皮质醇功能如何以及为何与从开始到疾病的物质使用表型相关。基因-环境相互作用和发育背景可能会影响减少药物使用问题的预防和干预措施的有效性。
There are many theories about the mechanisms of associations between hypothalamic-pituitary-adrenal (HPA) function (indexed by cortisol) and substance use. However, the potential for genes that contribute to both HPA function and substance use to confound the association (e.g., genetic confounding) has largely been ignored. We explore the potential role of genetics in cortisol-substance use associations, build a conceptual framework placing theories and mechanisms for how cortisol and substance use are related into a developmental progression, and develop new hypotheses based on our findings. We conclude that the relationship between cortisol function and substance use is complex, occurs at multiple levels of analysis, and is bidirectional at multiple phases of the substance use progression. Additionally, there is potential for genetic confounding in cortisol-substance use associations, and thus a need for genetically informed designs to investigate how and why cortisol function is associated with substance use phenotypes from initiation through disorder. Gene-environment interplay and developmental context are likely to impact the effectiveness of prevention and intervention efforts to reduce substance use problems.
