广州地区8138名大学生不同吸烟行为阶段转变的影响因素分析

目的探讨影响大学生不同吸烟行为阶段转换的因素。方法采用整群抽样法抽取广州地区某大学1～3年级在校大学生8138名,以自填式结构问卷调查学生所处的吸烟行为阶段及其相关影响因素。以尝试吸烟者和从未吸烟者作为“病例组”与“对照组”、不规律吸烟者和尝试吸烟者作为“病例组”与“对照组”、规律吸烟者和不规律吸烟者作为“病例组”与“对照组”,分别做多因素logistic分析,筛选影响不同吸烟行为阶段转变的因素。结果调查的8138名大学生中,尝试吸烟率、不规律吸烟率和规律吸烟率分别为19．6％、2．0％和1．1％,且三种吸烟行为流行率均随着年级的增加而增长。人大学后,仍有学生尝试吸烟或成为规律吸烟者。在男大学生,由不吸烟发展为尝试吸烟的影响因素有大学生的生源、父亲文化程度、吸烟相关知识和信念水平、室友吸烟;由尝试吸烟转变为不规律吸烟的影响因素是非医学生、吸烟相关信念、室友和同学吸烟;由不规律吸烟转变为规律吸烟的影响因素包括父亲文化程度、家庭人均收人。在女大学生,由不吸烟发展为尝试吸烟的影响因素是母亲文化程度、吸烟相关信念、室友吸烟;由尝试吸烟转变为不规律吸烟的影响因素为父亲文化程度、室友吸烟和同学吸烟。结论大学生不同吸烟行为阶段转变的影响因素是不同的,应根据他们所处的吸烟行为阶段,采取有针对性的措施预防或控制吸烟行为的形成和发展。

Study on the related factors of smoking behavior transition at different stages among undergraduate students I

Objective To explore the influencing factors of smoking behavior transition at different stage of smoking among undergraduate students. Methods 8138 undergraduate students from grade 1 to 3 were selected using cluster sampling method from an university in Guangzhou with their smoking behaviors and relevant factors studied through a self-administered questionnaire. Beginners, un-regular smokers and regular smokers were defined as "case group", while non-smokers, beginners and un-regular smokers were defined as "control group" accordingly. Three multivariable logistic regressions were separately conducted to explore the influencing factors of behavioral transition at different stage of smoking. Results Of the 8138 students investigated, the prevalence rates of beginners, un-regular smokers and regular smokers were 19.6% ,2.0% and 1.1% respectively; while all of the above said three rates increased with grades of the students. Some students might still try to smoke or become regular smoker in the university.In male undergraduate students, determinants for the transition from non-smokers to s mokers were: source of students, father' s educational level, smoking-related knowledge and belief, and smoking habit of the roommates. Risks that influencing the transition from beginners to un-regular smokers were: being non-medical students,smoking-related belief, roommates and classmates who were smokers and transition from un-regular smokers to regular smokers would include father' s educational level and average income of family. In female undergraduate students,influencing factors from non-smokers to beginners were mother s educational level , smoking-related belief , and roommates smokers , while father's educational level, roommates and classmates' smoking habits were significant associated with beginners' change to un-regular smokers. Conclusion The influencing factors related to the transition of different stage on smoking would he different in undergraduate students, and some specific measures should be taken based on the different stage of smoking.
