背景技术背景：研究人员在几项研究中检查了烟草危害认知与青少年烟草使用之间的相关性，但没有人前瞻性地解决危害认知与随后多种非香烟产品的新使用之间的关联。方法：对香烟、电子烟的特定产品的绝对和相对危害认知（电子烟）、雪茄、烟斗、水烟和无烟烟草在第1波（W1）收集（2013-2014）在全国代表性的美国烟草与健康研究人口评估（12-17岁; n = 10 081）中的青年中。在第2波（W2）（2014-2015年），计算了产品特定的新用途。调整后的相对危险度被用来估计W1的危害感知是否预测W2的新烟草使用。结果：赞成“很多危害”的年轻人的比例是最高的香烟（84.8%）和最低的电子烟（26.6%）;认为产品比香烟“更有害”的年轻人比例最高的是雪茄（30.6%），最低的是电子烟（5.1%）。在W1时未使用这些产品的青少年中，W2时特定产品的新使用率从9.1%（电子烟）到0.6%（烟斗）不等。在W1时认为不可燃烟草产品“没有或几乎没有危害”的青少年更有可能在W2时尝试过这些产品（P <0.05）。在W1时认为电子烟、水烟和无烟烟草比香烟“危害小”的青少年更有可能在W2时尝试这些烟草产品（P < .05）。针对特定产品的危害认知可能会防止年轻人新的烟草使用。
BACKGROUND: Researchers in several studies have examined correlations between tobacco harm perceptions and tobacco use in youth, but none have prospectively addressed the association between harm perceptions and subsequent new use across multiple noncigarette products.METHODS: Product-specific absolute and relative harm perceptions for cigarettes, electronic cigarettes (e-cigarettes), cigars, pipes, hookah, and smokeless tobacco were collected at wave 1 (W1) (2013-2014) among youth in the nationally representative US Population Assessment of Tobacco and Health Study (12-17 years of age; n = 10 081). At wave 2 (W2) (2014-2015), product-specific new use was calculated. Adjusted relative risks were used to estimate if harm perceptions at W1 predicted W2 new tobacco use.RESULTS: The proportion of youth who endorsed "a lot of harm" was highest for cigarettes (84.8%) and lowest for e-cigarettes (26.6%); the proportion of youth who thought products were "more harmful" than cigarettes was highest for cigars (30.6%) and lowest for e-cigarettes (5.1%). Among youth who had not used those products at W1, product-specific new use at W2 ranged from 9.1% (e-cigarettes) to 0.6% (pipes). Youth who believed that noncombustible tobacco products posed "no or little harm" at W1 were more likely to have tried those products at W2 (P < .05). Youth who viewed e-cigarettes, hookah, and smokeless tobacco as "less harmful" than cigarettes at W1 were more likely to try those tobacco products at W2 (P < .05).CONCLUSIONS: Low harm perceptions of noncigarette tobacco products predict new use of these products by youth within the next year. Targeting product-specific harm perceptions may prevent new tobacco use among youth.
