To examine the dimensionality of sensations experienced during initial tobacco smoking.
Cross-sectional survey.
Thirteen secondary schools located in British Columbia, Canada.
Data from 1187 adolescents who responded 'yes' to the question: 'Have you ever tried cigarette smoking, even one or two puffs?'.
Participants answered questions about their demographic characteristics, tobacco smoking history and sensations experienced during their initial smoking episodes.
The sensations appear to represent the following three separate but modestly correlated dimensions: a pleasant dimension defined by feeling good and relaxed; an unpleasant dimension defined by coughing, feeling sick and nervous; and a 'buzz' dimension defined by feeling high and dizzy. The three factors made statistically significant contributions to the prediction of transition to regular smoking (defined as having smoked at least 100 cigarettes in one's life-time) after adjusting for age, sex and age at first puff.
The results suggest that three relatively distinct physiological systems appear to explain the relationship between initial smoking sensations and probability of becoming a regular smoker. Researchers examining sensations experienced during initial tobacco smoking episodes should consider using a three-dimensional profile of symptoms composed of pleasant, unpleasant and buzz dimensions.
探讨初次吸烟时所体验到的感觉的维度。
横断面调查。
加拿大不列颠哥伦比亚省的 13 所中学。
对以下问题回答“是”的 1187 名青少年的数据：“你是否曾经尝试过吸烟，哪怕只是一两次？”。
参与者回答了有关他们的人口统计学特征、吸烟史以及初次吸烟时所体验到的感觉的问题。
这些感觉似乎代表了以下三个独立但适度相关的维度：一个愉快的维度，由感觉良好和放松定义；一个不愉快的维度，由咳嗽、恶心和紧张定义；以及一个“兴奋”的维度，由感觉兴奋和头晕定义。在调整年龄、性别和首次吸烟年龄后，这三个因素对向规律吸烟（定义为一生中至少吸过 100 支香烟）的转变有统计学意义的贡献。
结果表明，三个相对独立的生理系统似乎可以解释初次吸烟感觉与成为规律吸烟者的概率之间的关系。研究初次吸烟时所体验到的感觉的研究人员应该考虑使用由愉快、不愉快和兴奋三个维度组成的症状三维剖面图。
