简介：关于年轻人为了控制体重而使用电子烟的证据仍然很少。本研究旨在测试一个模型，在该模型中，负面身体自尊与电子烟使用之间的前瞻性关联是由电子烟使用的体重控制结果预期介导的。该模型在不同性别之间进行了测试。方法：在三个时间点（相隔 6 个月）从 2327 名年轻人（平均年龄 = 21.2；SD = 2.2；54% 女性）收集数据。收集了有关人口统计学、体重指数、身体自尊、电子烟使用的体重控制结果预期以及当前电子烟使用和吸烟情况的自我报告数据。结果：在女性中，我们发现，在女性中，较低的身体自尊对 1 年后当前使用电子烟的可能性较高有显着的间接影响，这是通过 6 个月随访时较高的体重控制结果预期介导的，并调整了人口统计、体重指数以及基线电子烟使用和吸烟情况。在男性中，没有发现身体自尊对体重控制预期或电子烟的使用有显着影响。结论：根据目前的研究结果，具有较高负面身体自尊的年轻成年女性出于体重控制动机而使用电子烟的风险更高。
Introduction: Evidence is still scarce regarding the use of e-cigarettes by young people for weight-control reasons. This study aimed to test a model in which the prospective association between negative body esteem and e-cigarette use is mediated by weight-control outcome expectancies for e-cigarette use. The model was tested across genders.Methods: Data were collected at three time points, 6 months apart, from 2327 young adults (mean age = 21.2; SD = 2.2; 54% women). Self-reported data were collected on demographics, body mass index, body esteem, weight-control outcome expectancies for e-cigarette use, and current e-cigarette use and cigarette smoking.Results: Among women, we found a significant indirect effect of lower body esteem on higher likelihood of current e-cigarette use 1 year later, mediated by higher weight-control outcome expectancies at 6-month follow-up, adjusting for demographics, body mass index, and baseline e-cigarette use and cigarette smoking. Among men, body esteem was not found to have significant effect on either weight-control expectancies or e-cigarette use.Conclusions: Based on the current findings, young adult women who have higher negative body esteem are at increased risk for using e-cigarettes for weight-control motives.
