The current study aimed to assess single product, dual, and polytobacco use in a young adult military population and how an enforced tobacco ban during training impacts these behaviors. Participants were 810 U.S. Airmen who reported tobacco use as civilians. Participants completed baseline and one-year follow-up surveys about their tobacco use from 2016 to 2019. Each product used by a participant was assigned a score based on their frequency of use, which were summed to create a total score. Change scores were calculated by determining the difference between baseline and follow-up frequency scores. Tobacco frequency score and the categorical change (e.g., increased, decreased) were compared between groups using t-tests and Chi-squared tests, respectively, adjusting for clustering effects by squadron and base. Among single product users, 44.58% quit using tobacco products, 47.1% remained single product users, and 8.32% became dual or polytobacco users. Among dual users, 39.1% quit, 43.1% became single product users, 14.2% remained dual users, and 3.7% became polytobacco users. Among polytobacco users, 29.9% quit, 43.4% became single product users, 17.9% became dual users, and 8.8% continued poly-tobacco use. Most participants reduced the number and frequency of tobacco products used. Implementing stringent policies that further restrict tobacco use may decrease tobacco product use or frequency of use.

目前的研究旨在评估年轻成年军人使用单一烟草、双重烟草和多种烟草的情况，以及训练期间强制实施的烟草禁令如何影响这些行为。参与者是 810 名美国空军士兵，他们将烟草使用报告为平民。从 2016 年到 2019 年，参与者完成了关于他们烟草使用情况的基线调查和为期一年的跟踪调查。参与者使用的每种产品都根据他们的使用频率分配了一个分数，将这些分数相加得到一个总分。通过确定基线和后续频率分数之间的差异来计算变化分数。分别使用 t 检验和卡方检验比较各组之间的烟草频率得分和分类变化（例如，增加、减少），并根据中队和基地的聚类效应进行调整。在单一产品用户中，44。58% 的人戒烟，47.1% 的人仍然是单一产品使用者，8.32% 的人成为双重或多种烟草使用者。在双重用户中，39.1% 戒烟，43.1% 成为单一产品用户，14.2% 仍然是双重用户，3.7% 成为多烟草用户。在复合烟草使用者中，29.9% 戒烟，43.4% 成为单一产品使用者，17.9% 成为双重使用者，8.8% 继续使用复合烟草。大多数参与者减少了使用烟草产品的数量和频率。实施进一步限制烟草使用的严格政策可能会减少烟草制品的使用或使用频率。4% 成为单一产品用户，17.9% 成为双重用户，8.8% 继续使用复合烟草。大多数参与者减少了使用烟草产品的数量和频率。实施进一步限制烟草使用的严格政策可能会减少烟草制品的使用或使用频率。4% 成为单一产品用户，17.9% 成为双重用户，8.8% 继续使用复合烟草。大多数参与者减少了使用烟草产品的数量和频率。实施进一步限制烟草使用的严格政策可能会减少烟草制品的使用或使用频率。
