Abstract

Background: Previous studies have demonstrated that involuntary smoking (e.g., secondhand smoke [SHS] and thirdhand smoke [THS]) is not only associated with an increased risk of several physical health problems, such as cardiovascular disease and cancer, but also impacts mental health, including depression and anxiety. However, the relationships between SHS and THS exposure and non-suicidal self-injury (NSSI), suicidal ideation (SI), and suicide attempts (SAs) remain unclear.

Methods: Participants were recruited at a Chinese vocational college via voluntary online surveys conducted on campus. Self-reported SHS exposure was determined by the frequency of contact with smokers or detecting tobacco odors in living environments, while THS was assessed through regular contact with smoker-contaminated surfaces (e.g., clothing, furniture, textiles). Logistic regression analysis was performed to evaluate the associations of SHS and THS exposure with the prevalence of NSSI, SI, and SAs in never-smoking participants.

Results: The study included 5716 participants (mean age = 19.3 years; females, 85.4%). The prevalence of SHS and THS exposure was 87.6% and 77.4%, with 8.8% reporting ≥15 min of SHS exposure on at least one day per week. After controlling for potential covariates, exposure to SHS (≥15 min on at least one day per week) was significantly associated with the odds of SAs (OR [95%CI] = 1.85 [1.17-2.91]). Additionally, daily THS exposure was significantly associated with increased past-year NSSI prevalence (2.35 [1.29-4.28]) compared to those without THS exposure, with similar associations observed for SI (2.11 [1.28-3.48]) and SAs (2.40 [1.23-4.69]).

Conclusions: Exposure to SHS and THS was significantly associated with increased likelihood of NSSI, SI, and SAs among young adults at a Chinese vocational college. Further studies are needed to validate these associations across more diverse populations.

非自愿吸烟与成年早期非自杀性自伤和自杀行为的关系。

背景：以往的研究表明，非自愿吸烟（如二手烟和三手烟）不仅与心血管疾病和癌症等几种身体健康问题的风险增加有关，而且还会影响心理健康，包括抑郁和焦虑。然而，SHS和三手烟暴露与非自杀性自伤（NSSI）、自杀意念（SI）和自杀企图（SAs）之间的关系尚不清楚。方法：在一所中国职业学院通过自愿在线调查的方式招募参与者。自我报告的SHS暴露是通过与吸烟者接触的频率或在生活环境中检测烟草气味来确定的，而三手烟是通过经常接触吸烟者污染的表面（如衣服、家具、纺织品）来评估的。采用Logistic回归分析来评估二手烟和三手烟暴露与不吸烟参与者自伤、自伤和自伤发生率之间的关系。结果：研究纳入了5716名参与者(平均年龄= 19.3岁；女性,85.4%)。SHS和三手烟暴露的患病率分别为87.6%和77.4%，其中8.8%报告每周至少有一天的SHS暴露≥15分钟。在控制潜在协变量后，暴露于SHS（每周至少一天≥15分钟）与sa的几率显著相关（OR [95%CI] = 1.85[1.17-2.91]）。此外，与没有接触三手烟的人相比，每天接触三手烟与过去一年自伤发生率增加显著相关（2.35 [1.29-4.28]），SI（2.11[1.28-3.48]）和sa（2.40[1.23-4.69]）也存在类似的关联。结论：在中国一所职业学院的年轻人中，暴露于SHS和THS与自伤、自伤和sa的可能性增加显著相关。需要进一步的研究来验证这些关联在更多不同的人群中。

期刊介绍： Toxics (ISSN 2305-6304) is an international, peer-reviewed, open access journal which provides an advanced forum for studies related to all aspects of toxic chemicals and materials. It publishes reviews, regular research papers, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in detail. There is, therefore, no restriction on the maximum length of the papers, although authors should write their papers in a clear and concise way. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of calculations and experimental procedure can be deposited as supplementary material, if it is not possible to publish them along with the text.
