: Recent research has shown obesity to be associated with e-cigarette use and appeal, but models have yet to examine how weight status may be related to e-cigarette dependence among e-cigarette users. : To increase our understanding of pathways from body mass index (BMI) to e-cigarette dependence, the present cross-sectional observational study investigated a model in which BMI, sweet taste responsiveness, and the interaction of BMI and sweet taste responsiveness are associated with e-cigarette dependence indirectly via seven conceptually-distinct motives for e-cigarette use. Data from several e-cigarette clinical laboratory research studies were pooled and analyzed; only current e-cigarette users were included in the analyses (N=330). Structural equation modeling was used to analyze the hypothesized model. : BMI was positively associated with lower social/environmental goad motives and higher weight control motives, and BMI x sweet taste interaction terms found that sweet taste responsiveness strengthened the association of BMI and weight control motives. BMI was not directly or indirectly associated with e-cigarette dependence nor was there a bivariate association between BMI and e-cigarette dependence. Sweet taste responsiveness was positively associated with greater affiliative attachment motives, cognitive enhancement motives, cue exposure-associative process motives, weight control motives, and affect enhancement motives. Sweet taste responsiveness was bivariately associated with e-cigarette dependence and mediation paths show indirect relations to e-cigarette dependence via three of the seven motives. : The findings suggest that sweet taste responsiveness, opposed to BMI, is associated with a wider range of e-cigarette use motives and indirectly relates to e-cigarette dependence via several e-cigarette use motives.
: 最近的研究表明，肥胖与电子烟的使用和吸引力有关，但模型尚未研究体重状况如何与电子烟使用者的电子烟依赖有关。: 为了更深入地了解体重指数 (BMI) 与电子烟依赖之间的关系，本横断面观察性研究调查了一个模型，其中 BMI、甜味反应性以及 BMI 和甜味反应性的相互作用通过电子烟使用的七个不同概念的动机间接与电子烟依赖相关。从多个电子烟临床实验室研究中收集和分析数据；仅包括当前电子烟使用者的分析（N=330）。使用结构方程模型分析假设模型。: BMI 与较低的社会/环境目标动机和较高的体重控制动机呈正相关，BMI 与甜味反应性的交互项发现，甜味反应性增强了 BMI 和体重控制动机的相关性。BMI 与电子烟依赖既没有直接关系，也没有间接关系，BMI 与电子烟依赖之间也没有双变量关系。甜味反应性与更大的亲和性依恋动机、认知增强动机、线索暴露-联想过程动机、体重控制动机和情感增强动机呈正相关。甜味反应性与电子烟依赖呈双变量相关，中介路径通过七个动机中的三个与电子烟依赖呈间接关系。: 研究结果表明，甜味反应性而不是 BMI 与更广泛的电子烟使用动机有关，并通过电子烟使用的几个动机与电子烟依赖间接相关。
