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.
虽然控制体重被认为是使用电子烟的一个动机，但关于控制体重与电子烟使用动机之间相关性的实证证据还很缺乏。本研究评估了体质指数（BMI）和甜味食物偏好（一种难以抗拒甜食和用食物调节情绪的概念）与年轻成年电子烟使用者控制体重的电子烟使用动机之间的主要影响和交互作用。2016 年 1 月至 8 月，在加利福尼亚州洛杉矶市招募了年龄在 18-35 岁之间、目前每周至少使用电子烟 1 天且持续使用 1 个月以上的年轻成年电子烟使用者（N=99；35%为女性）。参与者完成了一项电子烟产品吸引力实验，还参与了基于问卷的电子烟使用动机和参与者特征的测量，这是本文的重点。对电子烟使用控制体重动机结果的回归分析显示，BMI 没有主要影响，甜味食物偏好呈显著正相关，BMI 与甜味偏好存在交互关系。这种相互关系的基础是，在 BMI 的平均值和+1SD 水平上，甜味偏好与使用电子烟控制体重之间存在正相关，而在 BMI 的-1SD 水平上则没有关系。较高的甜味偏好可能会增加使用电子烟来控制体重，特别是在体重较高的年轻成年人中。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成年人的超重/肥胖问题。
