Results: A total of 348 cases were successfully matched, including 137 who have quit smoking and 211 who have not quit smoking. The difference in two groups of baseline data after matching was no statistically significant (P>0.05). During the epidemic period, the quit smoking rate (39.9%) was higher than that (25.0%) before the outbreak. The average daily smoking (7.10±8.473) was lower than that (7.77±8.405) before the outbreak. The score of Fagerstrom Test of Nicotine Dependence (1.91±2.449) was lower than that (4.35±2.518) before the outbreak; the score of the assessment scale of willingness to quit smoking (38.17±12.377) was higher than that (19.78±9.103) before the outbreak; the smoking change of non-smokers before and after outbreak was related to distress, calm psychological mood, relief of sorrow and boredom, smoking addiction and habit (P<0.05); nicotine dependence was related to the psychological mood of distress (P<0.05), and the willingness to quit smoking was related to the daily home stay time (P<0.05); For those who had quit smoking successfully, the smoking change was related to the psychological mood of distress, relief of sorrow and boredom, alleviation of stress, smoking addiction and habit (P<0.05); relapse thought was related to the psychological mood of distress, relief of sorrow and boredom, recreation and alleviation of stress (P<0.05); nicotine dependence was related to the daily home stay time, calm psychological mood and smoking addition (P<0.05), and the willingness to quit smoking related to recreation and smoking addition(P<0.05). Conclusions: During the epidemic period, people who tried to quit smoking reduced their smoking, nicotine dependence, and their willingness to quit smoking increased. During normalization of epidemic prevention and control, social activities decrease and home stay time increased, which created favorable conditions for quitting smoking and tobacco control. However, negative emotions during home stay, relief of sorrow and boredom and smoking addition may restore smoking behavior and relapse thought. It is recommended that family members provide more support and encouragement to smoke quitters, and supervise and help them reduce smoking. During normalization of epidemic prevention and control, the quit smoking service center should alleviate negative emotion of quitters and break connection between existing smoking habit and negative emotion and environmental temptation.
