从不吸烟大中学生对电子烟的交友作用认知和尝试倾向

Perceived friend-making effects and propensity to try e-cigarettes among never-smoking adolescent students

目的 了解中国从不吸烟大中学生对电子烟的交友作用认知情况及其与电子烟尝试倾向的关系,为青少年电子烟防控措施的制定和完善提供参考。方法 采用多阶段分层整群抽样方法,于2022年9月至2023年3月在中国的华北、长江三角洲、珠江三角洲、西南等区域抽取13座城市的2 577名大中学生进行问卷调查,对其中2 076名从不吸烟大中学生进行电子烟的交友作用认知和尝试倾向分析。结果 从不吸烟的大中学生中,728人(35.07%)有抽吸电子烟的倾向,68人(3.28%)认为抽吸电子烟对交友有利。多因素非条件Logistic回归分析显示,相较非常不同意抽吸电子烟的交友作用,对此持比较不同意、中立、比较同意和非常同意认知的从不吸烟大中学生尝试抽吸电子烟的倾向均上升[OR值(95%CI)分别为2.73(2.16~3.44)、2.52(1.83~3.48)、4.34(2.19~8.60)和3.01(1.36~6.65)],对电子烟危害的认知、好友的电子烟抽吸行为和个人的消极情绪也与从不吸烟大中学生的电子烟尝试倾向存在关联(OR=1.34~1.91,P值均<0.05)。结论 从不吸烟大中学生对电子烟的交友作用认知与其尝试电子烟的倾向显著相关。建议加强对青少年的宣传教育,降低电子烟对青少年的健康风险。

Objective The current study aims to understand perceptions of electronic cigarette(e-cigarette)smoking among Chinese adolescents who have never smoked and its role in forming friendships,while considering the association of the odds of trying e-cigarettes,so as to provide a basis for developing an e-cigarette control policy among this population.Methods From September 2022 to March 2023,2577 adolescent students from 13 cities of the Yangtze and Pearl River Deltas,and North and Southwest China were surveyed through a questionnaire by a multi-stage cluster sampling method.The study analyzed the perceived role of e-cigarette smoking in making friends,and its influence on intentions to try them among 2076 never-smoking adolescent students.Results Among the adolescent students,728(35.07%)were inclined to try e-cigarettes,and 68(3.28%)believed that e-cigarettes play a positive factor in making friends.The results of the Logistic regression analysis showed that compared to those who strongly disagreed that e-cigarettes play a role in making friends,intentions to try e-cigarettes were higher among never-smoking adolescent students who had responded"somewhat disagree""neutral""somewhat agree"and"strongly agree"times,respectively.Perceived harm caused by e-cigarettes,vaping behavior of friends and negative emotions were also significantly related to the odds of trying e-cigarettes(OR=1.34-1.91,P<0.05).Conclusion Perceptions of the role of e-cigarettes in friend-making among never-smoking adolescent students were significantly associated with their intentions to try e-cigarettes.It is recommended to strengthen awareness and education about the harm caused by e-cigarettes among adolescents in order to reduce the associated health risks among this population.
