■在过去几年中,青少年电子烟(EC)的使用迅速增加。确定易感青年并防止他们吸收EC至关重要。本研究旨在调查影响青少年使用EC易感性的因素。
■这项研究采用了横断面调查设计,采用多中心分层整群抽样的方法,选取上海市的两所初中和两所高中,广州,和成都。所选学校中每个年级的三分之一班级都参与了这项调查。在获得父母的知情同意后,向学生分发了一份匿名和自我管理的问卷。问卷是基于健康行为的生态学模型设计的。使用多变量逻辑回归确定EC易感性与协变量之间的关联。
■在2,270名从未吸过烟的学生中,38.0%易感ECs。Logistic回归分析确定了不同水平影响易感性的因素。个人因素包括高中生(OR=1.34,95%CI:1.08-1.65),感觉寻求者(OR=1.11,95CI:1.08-1.14),学习成绩差(OR=1.24,95%CI:1.01-1.54),曾经使用过香烟(OR=2.27,95%CI:1.29-4.01),不知道电子烟产生的二手烟(OR=1.56,95%CI:1.25-1.96),同意“我不想闲逛”(OR=0.79,95%CI:0.64-0.97),同意“EC比香烟更时尚”(OR=2.50,95%CI:1.72-3.62)和对电子烟的有利态度(OR=5.09,95%CI:3.78-6.85)与对EC的易感性显着相关。在人际关系层面,认为自己不会因电子烟易感性增加而受到父母惩罚的学生(OR=1.27,95%CI:1.01-1.59)。在社区层面,EC广告的暴露(OR=1.81,95%CI:1.46-2.25),暴露于危险信息(OR=0.76,95%CI:0.59-0.97)并在日常生活中看到电子烟(OR=2.11,95%CI:1.62-2.74),与青年对ECs的易感性有统计学意义。
■在很大一部分从未吸烟的青少年中观察到EC易感性,受不同层面因素的影响。这项研究强调了迫切需要全面的干预策略,以防止年轻人对ECs的易感性。
UNASSIGNED: Youth e-cigarette (EC) use has rapidly increased in the last few years. It is crucial to identify the susceptible youth and prevent them from EC uptake. This study was conducted to investigate factors that affect youth susceptibility to EC use.
UNASSIGNED: This study employed a cross-sectional survey design, utilizing multi-center stratified cluster sampling method to select two junior high schools and two senior high schools in Shanghai, Guangzhou, and Chengdu. One-third of classes of each grade in the selected schools were involved in this survey. After obtaining the informed consent of parents, an anonymous and self-administered questionnaire was distributed to students. Questionnaire was designed based on the Ecological Models of Health Behavior. Associations between EC susceptibility and covariates were identified using multivariate logistic regression.
UNASSIGNED: Among 2,270 students who had never vaped, 38.0% were susceptible to ECs. Logistic regression analysis identified factors on different levels affecting the susceptibility. Individual factors included senior high school students (OR = 1.34, 95% CI: 1.08-1.65), sensation seeker (OR = 1.11, 95%CI: 1.08-1.14), poor academic performance (OR = 1.24, 95% CI: 1.01-1.54), ever cigarette user (OR = 2.27, 95% CI: 1.29-4.01), unaware of the second-hand smoke from vaping (OR = 1.56, 95% CI: 1.25-1.96), agreeable with \"I do not want to hang around vapers\" (OR = 0.79, 95% CI: 0.64-0.97), agreeable with \"ECs are more fashionable than cigarette\" (OR = 2.50, 95% CI: 1.72-3.62) and favorable attitudes toward vaping (OR = 5.09, 95% CI: 3.78-6.85) were significantly associated with susceptibility to ECs. At interpersonal level, students who believe they would not be punished by parents for vaping increased susceptibility (OR = 1.27, 95% CI:1.01-1.59). At community level, exposure of EC advertising (OR = 1.81, 95% CI:1.46-2.25), exposure to hazard information (OR = 0.76, 95% CI: 0.59-0.97) and seeing vaping in daily life (OR = 2.11, 95% CI: 1.62-2.74), were statistically significantly associated with youth susceptibility to ECs.
UNASSIGNED: EC susceptibility was observed in a substantial proportion of adolescents who had never vaped, influenced by factors on different levels. This research underscores the urgent need for comprehensive intervention strategies to prevent the youth susceptibility to ECs.
