本研究的目的是确定青少年吸烟者（其吸烟史和尼古丁依赖症状各不相同）是否表现出与依赖性青少年和成人吸烟者中通常观察到的相似的抽吸量和持续时间减少。此外，我们研究了吸烟轨迹是否受到个体差异因素的调节，以及吸烟过程中的吸烟地形是否可以预测依赖症状的升级。我们使用分层线性模型评估了78名青少年轻度吸烟者吸烟过程中的吸烟地形图（抽吸次数、持续时间、体积、最大流速[速度]和抽吸间隔）。我们检查了地形轨迹的调节因子（焦虑、抑郁、尼古丁依赖），以及吸烟地形是否预测了2年内依赖性的任何变化。在吸烟过程中，抽吸量和抽吸持续时间减少，而抽吸速度和抽吸间隔增加。吸烟量和持续时间的斜率受焦虑和抑郁症状的影响。此外，具有不太“典型”的地形图模式的个体（在吸烟过程中表现出稳定或增加的量和持续时间）在随后的2年中表现出高度的依赖性升级。我们的研究结果表明，青少年轻度吸烟者在吸烟过程中自我调节尼古丁，类似于依赖性青少年和成年吸烟者的报告。然而，单支香烟的自我调节受到某些情感因素的影响。这些研究结果的影响和青少年吸烟研究的未来方向进行了讨论。
The objective of this study was to determine whether adolescent smokers, who varied in their smoking histories and symptoms of nicotine dependence, exhibit any decrease in puff volume and duration similar to that typically seen in dependent adolescent and adult smokers. Moreover, we examined whether puffing trajectories were moderated by individual difference factors, as well as whether puffing topography over the course of smoking a single cigarette was predictive of an escalation in dependence symptoms. We assessed smoking topography (puff number, duration, volume, maximum flow rate [velocity], and inter-puff interval) over the course of smoking a single cigarette in a sample of 78 adolescent light smokers, using hierarchical linear modeling. We examined moderators (anxiety, depression, nicotine dependence) of the topographic trajectories, as well as whether smoking topography predicted any change in dependence over a 2-year period. Puff volume and puff duration decreased over the course of smoking the cigarette, whereas puff velocity and inter-puff interval increased. Slopes for puff volume and duration were moderated by anxiety and depressive symptoms. Moreover, individuals with a less “typical” topography pattern (exhibited stable or increasing volume and duration over the course of smoking the cigarette) demonstrated a heightened dependence escalation in the subsequent 2 years. Our findings suggest that adolescent light smokers self-regulate nicotine during the course of smoking a single cigarette, similar to that reported in dependent adolescent and adult smokers. However, single cigarette self-regulation was influenced by certain affective factors. Implications of these findings and future directions for adolescent smoking research are discussed.
