While evidence demonstrates that the industry's marketing of cigarettes with higher filter ventilation (FV) misleads adults about their health risks, there is no research on the relationships between FV, risk perceptions and smoking trajectories among youth (ages 12-17) and young adults (ages 18-24).
Data on FV levels of major US cigarette brands/sub-brands were merged with the Population Assessment of Tobacco and Health Study to examine whether FV level in cigarettes used by wave 1 youth/young adults (n=1970) predicted continued smoking at waves 2-4, and whether those relationships were mediated by perceived risk of their cigarette brand. FV was modelled based on tertiles (0.2%-11.8%, low; 11.9%-23.2%, moderate; 23.3%-61.1%, high) to predict daily smoking, past 30-day smoking and change in number of days smoking at successive waves.
The odds of perceiving one's brand as less harmful than other cigarette brands was 2.21 times higher in the high versus low FV group (p=0.0146). Relationships between FV and smoking outcomes at successive waves were non-significant (all p>0.05).
Youth and young adults who use higher FV cigarettes perceived their brand as less harmful compared with other brands. However, level of FV was not associated with continued smoking.
尽管有证据表明，该行业对高过滤通风（FV）香烟的营销误导了成年人对其健康风险的认知，但目前尚无研究探讨 FV 与青少年（12-17 岁）和年轻成年人（18-24 岁）之间风险认知和吸烟轨迹之间的关系。
将美国主要香烟品牌/子品牌的 FV 水平数据与人口烟草与健康评估研究相合并，以检验第 1 波青少年/年轻成年人（n=1970）使用的香烟 FV 水平是否可预测第 2-4 波的持续吸烟，以及这些关系是否通过对其香烟品牌风险感知的中介作用来预测。基于 tertiles（0.2%-11.8%，低；11.9%-23.2%，中；23.3%-61.1%，高）来对 FV 进行建模，以预测每日吸烟、过去 30 天吸烟以及在连续波次中吸烟天数的变化。
与低 FV 组相比，高 FV 组认为自己的品牌比其他香烟品牌危害小的可能性高 2.21 倍（p=0.0146）。在连续波次中 FV 与吸烟结果之间的关系无统计学意义（所有 p>0.05）。
使用高 FV 香烟的青少年和年轻成年人认为与其他品牌相比，他们的品牌危害较小。然而，FV 水平与持续吸烟无关。
