目的：鉴于我国青少年吸烟率的不断递升，有必要探索一种适合青少年特点的控烟模式。方法：采用整群随机抽样法对5266名中学生吸烟现状及其相关因素进行调查分析。结果：学生中尝试吸烟率达26．8％，吸第一支烟的学生以10岁最多，其次为12岁，14岁和15岁，学生中79．2％是受他人影响而为。在尝试吸烟中有32．2％将发展为再次吸烟。吸烟学生较多是在家中或较隐蔽处吸烟。促使学生放弃吸烟行为的主要因素是懂得吸烟危害健康、异性朋友反对和丰富的课余活动。结论：学校应对学生加强健康教育，而推迟吸第一支烟的年龄是预防青少年吸烟的关键。学校控烟工作的重点应放在小学高年级和初中阶段，同时还必须从学校、家庭、社会及个人多方面探讨其根源，找出对策。
Objective: In view of the rising rate of smoking among adolescents in our country, it is necessary to explore a tobacco control mode suitable for the characteristics of adolescents. Methods: A total of 5266 middle school students smoking status and related factors were investigated by cluster sampling method. Results: Students attempted to smoke at a rate of 26.8%. Students smoking the first cigarette were at 10 years of age, followed by 12, 14 and 15 years of age, and 79.2% of students were influenced by others. 32.2% of the attempts to smoke will develop into smoking again. Smoking students smoke more at home or in less hidden places. The main factors that motivate students to quit smoking are knowing that smoking is harmful to their health, heterosexual friends who oppose and enrich after-school activities. Conclusion: Schools should strengthen students’ health education. The delay in smoking the first cigarette is the key to preventing juvenile smoking. The focus of school tobacco control should be placed in the upper primary and junior high school stages, but also from the school, family, community and individuals to explore its root causes and identify countermeasures.
