Youth tobacco use behaviors are predictive of patterns in adulthood and effect long-term health outcomes. Yet, few studies have examined the effect of initial subjective experiences (ISEs) during first tobacco use, which has been found to be an indicator of individuals. sensitivity to nicotine and vulnerability to dependence.
The present study aimed to determine the prevalence of ISEs across a variety of tobacco products, evaluate the factor structure of ISEs by first tobacco product used, and examine the relationship between ISEs and recent (30-day) use of tobacco products across time, using a university sample.
Exploratory factor analyses were conducted to identify latent factors present with respect to items measuring ISEs with tobacco, separately by tobacco product (e.g. cigarettes, cigars, hookah, e-cigarettes). Factor scores for positive and negative ISEs were calculated. Multiple logistic regression analyses were conducted to examine associations between ISEs and recent use of each tobacco product, adjusted for age at first use, sex, race/ethnicity, and cohort.
ISEs differ by the first tobacco product used. Associations between factor scores for positive and negative ISEs and recent use were found across a variety of tobacco products. Overall, positive ISEs were more strongly associated with recent use, relative to negative ISEs.
Further research is needed to identify genetic and biological pathways and social contexts influencing initial subjective experiences with tobacco use, in efforts to delay the initiation for tobacco use and reduce risk for continued use among young adults.
青少年的烟草使用行为可预测成年后的模式，并对长期健康结果产生影响。然而，很少有研究探讨初次使用烟草时的初始主观体验（ISE）的影响，因为它是衡量个体对尼古丁的敏感性和对依赖易感性的一个指标。
本研究旨在确定各种烟草产品中 ISE 的流行程度，通过初次使用的烟草产品评估 ISE 的因子结构，并在时间上考察 ISE 与最近（30 天）烟草产品使用之间的关系，使用的是大学样本。
使用探索性因子分析，分别按烟草产品（如香烟、雪茄、水烟、电子烟）来确定与测量 ISE 相关的项目中存在的潜在因子。计算了正性和负性 ISE 的因子得分。采用多因素逻辑回归分析，对 ISE 与最近使用每种烟草产品之间的关联进行了检验，调整了初次使用的年龄、性别、种族/民族和队列。
ISE 因初次使用的烟草产品而异。在各种烟草产品中，正性和负性 ISE 因子得分与最近使用之间存在关联。总体而言，正性 ISE 与最近使用的关联强于负性 ISE。
需要进一步研究以确定影响初次使用烟草时的初始主观体验的遗传和生物学途径以及社会背景，以便努力延缓烟草使用的开始，并减少年轻人继续使用烟草的风险。
