There is a paucity of research on patterns of attempts at smoking cessation, success, and influencing factors in adolescents. This study aims to analyze the prevalence of ex-smokers and current smokers with cessation attempts in adolescents worldwide and to identify the factors that affect cessation attempts along with outcomes.
This study utilized the Global Youth Tobacco Survey (2010-2021) to investigate tobacco use among adolescents aged 13-15 years. Smoking status was categorized into two groups: ex-smokers, who successfully stop, and current smokers with cessation attempts. Prevalence is presented as weighted rates with 95% confidence intervals (CIs). Factors influencing smoking cessation attempts and success were assessed using adjusted odds ratios (aORs) with 95% CIs.
Totally 9.96% of adolescents worldwide were classified as ex-smokers (95% CI 9.30%-10.63%), while 7.29% were current smokers with cessation attempts (95% CI 6.51%-8.06%). The prevalence of ex-smokers was highest in settings where primary care facilities provide tobacco-dependence treatment. The highest prevalence of current smokers with cessation attempts was observed in community-based settings. Education in schools has been shown to be associated with both smoking cessation attempts [aOR, 1.44 (95% CI 1.36-1.53)] and success [aOR, 1.16 (95% CI 1.10-1.22)]. Individuals who successfully stop smoking had lower secondhand smoke exposure than current smokers, while smokers with cessation attempts experienced higher exposure than smokers without such attempts.
The prevalence of ex-smokers and current smokers with cessation attempts remains low. School-based educational programs have proven effective in promoting smoking cessation attempts and reducing exposure to secondhand smoke is essential for successful stop.
关于青少年戒烟尝试模式、成功率及影响因素的研究较少。本研究旨在分析全球青少年中已戒烟者和有戒烟尝试的当前吸烟者的患病率，并确定影响戒烟尝试及其结果的因素。
本研究利用全球青少年烟草调查（2010 - 2021年）来调查13 - 15岁青少年的烟草使用情况。吸烟状况分为两组：成功戒烟的已戒烟者，以及有戒烟尝试的当前吸烟者。患病率以加权率及95%置信区间（CIs）表示。使用调整后的优势比（aORs）及95% CIs评估影响戒烟尝试和成功的因素。
全球共有9.96%的青少年被归类为已戒烟者（95% CI 9.30% - 10.63%），而7.29%为有戒烟尝试的当前吸烟者（95% CI 6.51% - 8.06%）。在初级保健机构提供烟草依赖治疗的地区，已戒烟者的患病率最高。在社区环境中观察到有戒烟尝试的当前吸烟者患病率最高。学校教育已被证明与戒烟尝试[aOR，1.44（95% CI 1.36 - 1.53）]和成功率[aOR，1.16（95% CI 1.10 - 1.22）]均相关。成功戒烟的个体比当前吸烟者接触二手烟的程度更低，而有戒烟尝试的吸烟者比没有此类尝试的吸烟者接触二手烟的程度更高。
已戒烟者和有戒烟尝试的当前吸烟者的患病率仍然较低。基于学校的教育项目已被证明在促进戒烟尝试方面有效，减少二手烟暴露对于成功戒烟至关重要。
