While weight control is anecdotally reported as a motive for e-cigarette use, empirical evidence on correlates of weight control vaping motives is largely absent. This study evaluated main effect and interactive associations of body mass index (BMI) and sweet taste food preference—a construct defined by difficulty resisting sweet foods and consuming foods for mood regulation— with e-cigarette weight control motives among young adult e-cigarette users. Young adults (N = 99; 35% women) between the ages of 18–35 who currently used e-cigarettes ≥1 day/week for ≥1 month were recruited in Los Angeles, CA in January–August 2016. Participants completed an e-cigarette product appeal experiment that also involved questionnaire-based measures of vaping motives and participant characteristics, which are this paper's focus. Regression analysis of e-cigarette use for weight control motive outcomes revealed no main effect of BMI, a significant main effect positive association for sweet taste food preference, and a BMI x sweet taste preference interactive relation. The interaction was underpinned by a positive association between sweet taste preference and use of e-cigarettes for weight control at mean and + 1SD levels of BMI and no relation at -1SD BMI levels. Higher sweet taste preference might increase use of e-cigarettes for weight control, particularly in young adults with higher weight. Taking into account sweet taste preference might be useful in interventions promoting healthy weight control strategies instead of e-cigarette use to address overweight/obesity in young adults.

虽然据传控制体重是电子烟使用的一个动机，但关于体重控制吸电子烟动机相关性的经验证据基本上不存在。本研究评估了体重指数 (BMI) 和甜味食物偏好的主要影响和交互关联——一种由难以抵抗甜食和食用食物来调节情绪的结构——与年轻成人电子烟用户的电子烟体重控制动机. 年轻人（N = 99; 35% 的女性）于 2016 年 1 月至 8 月在加利福尼亚州洛杉矶招募了目前使用电子烟≥1 天/周且≥1 个月的 18-35 岁女性。参与者完成了一项电子烟产品吸引力实验，该实验还涉及基于问卷的电子烟动机和参与者特征测量，这是本文的重点。使用电子烟对体重控制动机结果的回归分析显示，BMI 没有主效应，主效应与甜味食物偏好显着正相关，并且 BMI x 甜味偏好交互关系。这种相互作用的基础是甜味偏好与使用电子烟控制体重在平均和 + 1SD BMI 水平上呈正相关，而在 -1SD BMI 水平上没有相关性。较高的甜味偏好可能会增加使用电子烟来控制体重，尤其是在体重较高的年轻人中。考虑到甜味偏好可能有助于促进健康的体重控制策略，而不是使用电子烟来解决年轻人的超重/肥胖问题。
