Abstract：
Objective: The present study aims to examine whether secondhand smoke exposure (SHSE) in university students can affect three indices of self-satisfaction related to depression as indiced by appearance, weight, and freedom of life choice. Participants: We collected data from 740 nonsmoking students in the summer of 2018, of which 57.84% were exposed to secondhand smoke. Methods: Depressive symptoms, SHSE, smoking status, weight satisfaction, appearance satisfaction, and freedom of life choice were self-reported via a questionnaire. Results: The generalized linear analyses revealed that SHSE was linked to lower scores of perceived freedom of life choice but not significantly associated with weight nor appearance satisfaction. The mediation analyses indicated that perceived freedom of life choice fully mediated the association between SHSE and depressive symptoms. Conclusions: These findings shed light on the importance of SHSE and its effects on mental health in university students. Preventive strategies should therefore locally target university campuses.

目的：本研究旨在研究大学生二手烟暴露（SHSE）是否会影响以外表为指标的与抑郁相关的三个自我满意度指标。体重,生活选择的自由。参与者：我们收集了2018年夏季740名非吸烟学生的数据，其中57.84％暴露于二手烟。方法:抑郁症状,SHSE,吸烟状况,体重满意度，外观满意度，生活选择的自由是通过问卷自我报告的。结果：广义线性分析显示，SHSE与较低的生活选择自由得分有关，但与体重或外观满意度无关。调解分析表明，感知的生活选择自由完全介导了SHSE与抑郁症状之间的关联。结论：这些发现揭示了SHSE的重要性及其对大学生心理健康的影响。因此，预防策略应针对当地的大学校园。
