A comparison of smoking behaviors among medical and other college students in China.

A survey of students' smoking in China (n = 1896), comparing medical students with college students in non-medical majors, was carried out to determine whether a medical education has a preventive effect on smoking uptake. The survey, sampling students from 12 universities in three cities, found no significant differences between medical and non-medical students in smoking prevalence (40.7% versus 45.1% for males, 4.4% versus 6.0% for females), in 'ever smoked' groups, in 'ever smoked 100 cigarettes' groups or in years of smoking. For both student groups, smoking prevalence increased with age and with years of college. However, one significant difference was found among the smokers: medical students were more likely to be occasional smokers than were non-medical students (75.3% occasional smokers among medical students who smoked versus 60.6% among non-medical students). These results suggest that a medical education had little effect on these students' decisions to smoke, but that it may have modified their consumption level. Future studies are needed to ascertain factors affecting the decision to smoke and to identify possible early adopters of a non-smoking culture in China. Action on a societal level is urgently needed to change Chinese social norms regarding smoking.
