This work examines the relationship between local flavor policy exposure and any tobacco product use and flavored tobacco product use among U.S. youth and young adults, as well as the equity potential of these policies by race/ethnicity. Participants were aged 15–36 ( = 10,893) surveyed from September–December 2019 using national, address- and probability-based sampling. Local flavor policies enacted before survey completion were linked to participant home address. Weighted cross-sectional multivariable logistic regression examined individual coverage by flavor policy vs. no flavor policy, with current any tobacco or flavored tobacco use, controlling for individual and county-level demographics, psychosocial variables, and other tobacco control policies. Interactions between race/ethnicity and any tobacco use and flavored tobacco use were assessed. Those covered by a flavor policy vs. no policy had lower odds of any tobacco use (aOR = 0.74, 95% CI = 0.55–1.00) and current flavored tobacco use (aOR = 0.67, 95% CI = 0.48–0.93). Compared with Non-Hispanic (NH)-White individuals, NH-Black individuals (aOR = 1.08, CI = 1.04–1.12) had higher odds of any tobacco use, and non-Hispanic Asian individuals had lower odds of any tobacco use (aOR = 0.67, CI = 0.53–0.85). Hispanic individuals exposed to policy had lower odds of flavored tobacco use compared to NH-White peers. Exposure to flavor restriction policies is associated with lower odds of any tobacco and flavored use among youth and young adults. Flavor restrictions may be beneficial in reducing tobacco use in youth from diverse racial/ethnic backgrounds. However, passing policies covering NH-Black individuals is needed to mitigate disparities in tobacco use by flavor policy coverage over time.

研究美国青少年和年轻人中调味烟草产品政策限制与调味烟草产品使用的关系

这项工作研究了美国青少年和年轻人中当地风味政策暴露与任何烟草产品使用和调味烟草产品使用之间的关系，以及这些政策按种族/族裔划分的公平潜力。 2019 年 9 月至 12 月期间，使用基于地址和概率的全国抽样对参与者进行了调查，调查对象年龄为 15-36 岁 (= 10,893 人)。调查完成前制定的地方风味政策与参与者的家庭住址相关。加权横截面多变量逻辑回归检查了调味政策与无调味政策的个人覆盖率，以及当前任何烟草或调味烟草的使用情况，控制了个人和县级人口统计数据、心理社会变量和其他烟草控制政策。评估了种族/族裔与任何烟草使用和调味烟草使用之间的相互作用。与没有政策覆盖的人群相比，那些接受香料政策的人使用任何烟草的几率（aOR = 0.74，95% CI = 0.55–1.00）和当前使用香料烟草的几率（aOR = 0.67，95% CI = 0.48–0.93）较低。与非西班牙裔 (NH) 白人相比，NH 黑人（aOR = 1.08，CI = 1.04–1.12）使用任何烟草的几率较高，而非西班牙裔亚洲人使用任何烟草的几率较低（aOR = 0.67，置信区间 = 0.53–0.85）。与新罕布什尔州白人同龄人相比，受到政策影响的西班牙裔人使用调味烟草的几率较低。接触香料限制政策与青少年和年轻人使用任何烟草和香料的可能性较低有关。口味限制可能有利于减少来自不同种族/民族背景的青少年的烟草使用。然而，随着时间的推移，需要通过覆盖非裔黑人个人的政策，以通过口味政策覆盖范围来缩小烟草使用的差异。
