Objective: To explore determinants of smoking behavior transition at different stage among undergraduate students.

Methods: 8138 undergraduate students from grade 1 to 3 were selected with cluster sampling method from an university in Guangzhou with their smoking behaviors and relevant factors studied through a self-administered questionnaire. Beginners, irregular smokers and regular smokers were defined as “case group”, while non-smokers, beginners and irregular smokers were defined as “control group” accordingly. Three multivariable logistic regressions were separately conducted to explore the determinants of behavioral transition at different stage of smoking.

Results: Of the 8138 students investigated, the prevalence of beginners, irregular 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 beginners were: source of students, father's educational level, smoking-related knowledge and belief, and smoking habit of the roommates; Risks that influence the transition from beginners to irregular smokers were: being non-medical students, smoking-related belief, roommates and classmates' smoking habit; and the transition from irregular smokers to regular smokers included father's educational level and average income of family. In female undergraduate students, influence factors for the transition 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 irregular smokers.
