The FDA's policies restricting sale of sweet flavored cartridge-based and disposable electronic nicotine delivery systems (ENDS) comprise important steps toward curbing adolescent ENDS use. However, additional evidence is needed about the contribution of specific flavors to adolescents' ENDS use. This study investigated the effects of flavor use on same day vaping behaviors, and next day intentions and willingness.
We collected ecological momentary assessments (EMA) from 50 adolescent past two-week vapers (ages 14-17) over 14 days. Daily EMA data were collected on vaping occasions, total puffs, vaping intentions, vaping willingness, and flavor used.
On average, data were obtained on 13.4 days per participant (670 observations). Participants vaped flavors on 87% of days (fruit = 55%; mint = 30%; tobacco = 6%; menthol = 5%, and candy, sweets, or chocolate = 5%). On days when participants vaped fruit flavors, they took more puffs (r = 0.13, p = .030). On days when they vaped tobacco flavor, they reported more vaping occasions (r = 0.20, p = .005) and more puffs (r = 0.15, p = .033). On days when they vaped because of flavor appeal, they reported more vaping occasions (r = 0.19, p = .001) and more puffs (r = 0.24, p < .001). On days when they vaped menthol flavor, they were less likely to report willingness to vape the next day (r = -0.14, p = .042). Adolescents who reported vaping due to flavor appeal were more likely to report intentions (OR = 5.63, p = .035) and willingness to vape the next day (r = 0.23, p < .001) CONCLUSION: These findings provide additional support for policies restricting the sale of flavored ENDS products to adolescents.
FDA 限制销售甜味墨盒式和一次性电子烟的政策是遏制青少年使用电子烟的重要步骤。然而，需要更多证据来证明特定口味对青少年使用电子烟的贡献。本研究调查了口味使用对青少年当日吸电子烟行为以及次日吸电子烟意愿和意愿的影响。
我们在 14 天内从 50 名过去两周内吸过电子烟的青少年（年龄在 14-17 岁之间）那里收集了生态瞬间评估（EMA）数据。每天的 EMA 数据包括吸电子烟的次数、总吸烟量、吸电子烟的意图、吸电子烟的意愿和使用的口味。
平均而言，每位参与者的数据获得了 13.4 天（670 次观察）。参与者在 87%的日子里吸食口味电子烟（水果味=55%；薄荷味=30%；烟草味=6%；薄荷醇味=5%，以及糖果、甜食或巧克力味=5%）。在参与者吸食水果口味的日子里，他们吸了更多的烟（r=0.13，p=0.030）。在他们吸食烟草口味的日子里，他们报告了更多的吸烟次数（r=0.20，p=0.005）和更多的吸烟量（r=0.15，p=0.033）。在他们因为口味而吸电子烟的日子里，他们报告了更多的吸烟次数（r=0.19，p=0.001）和更多的吸烟量（r=0.24，p<0.001）。在他们吸食薄荷醇口味的日子里，他们不太可能报告第二天愿意吸电子烟（r=-0.14，p=0.042）。报告因为口味而吸电子烟的青少年更有可能报告第二天的吸电子烟意图（OR=5.63，p=0.035）和意愿（r=0.23，p<0.001）。
这些发现为限制向青少年销售调味电子烟产品的政策提供了更多支持。
