A retrospective study of smoking cessation intervention among university students

This retrospective study investigated the effect of smoking cessation intervention (SCI) among university students in China. Around 192 eligible smokers among university students were included, and were assigned to an intervention group (n=100), and a control group (n=92). All included subjects in both groups were recommended to increase fruits and vegetables consumptions. Additionally, participants in the intervention group also underwent SCI therapy for a total of 4 weeks. The outcome measurements consisted of a number of students quit smoking, daily cigarettes, quit attempts, mean days of smoking in the past 30 days, and also stage of change. After 4-week treatment, SCI neither can decrease the number of students quit smoking (P=.21), daily cigarettes (P=.21), quit attempts (P=.07), and mean days of smoking in past 30 days (P=.77), nor can enhance the stage of change (precontemplation, P=.18; contemplation, P=.59; preparation, P=.46). The results of this study showed that after 4-week therapy, SCI may be ineffective for smokers among university students in Chinese.
