Abstract:

Objective: To explore the effect and influencing factors of smoking cessation among smokers after intervention in the smoking cessation clinic, and propose measures for improving smoking cessation intervention. Methods: Using a prospective intervention study design, intensive smoking cessation intervention was conducted among smokers who were consulted at the Quitting Clinic of Guangzhou Chest Hospital from January 2021 to January 2022, with clear recommendations for quitting smoking. Then, standardized follow-up visits were conducted for 1 week, 1 month, 3 months, and 6 months in sequence. Those who did not quit smoking and those who quit smoking for less than 7 days were recorded as quitting failure groups, while those who quit smoking for more than 7 days (including relapse after quitting for 7 days) were recorded as quitting success groups for 7 days. After completing a 6-month follow-up, the smoking cessation behavior, smoking cessation outcomes, and relapse status of smokers were analyzed, and the influencing factors of success or failure in quitting smoking were explored. Results: A total of 79 smokers completed a 6-month follow-up. Twenty-three successfully quit smoking, 15 did not quit smoking, and 41 relapsed smokers. Relapse occurred in all follow-up periods, but most relapse occurred within the first week after quitting smoking, accounting for 48.8% (20/41). The success rate of quitting smoking was 55.7% (44/79). Comparing the baseline status of the two groups, the average daily smoking volume in the successful quitting group (17.43±4.95) was significantly lower than that in the unsuccessful quitting group (21.43±7.43), with a statistically significant difference (t=-2.859, P=0.005); The score of tobacco dependence (5.43±1.11) was significantly lower than that of smoking cessation failure group (6.14±0.97), with a statistically significant difference (t=-2.987, P=0.004). Multivariate logistic regression analysis showed that daily average smoking volume (≥20) was an independent influencing factor for smoking cessation failure (OR (95%CI): 4.441 (1.652 to 11.940), P=0.003). Conclusion: After intensive intervention in the smoking cessation clinic, smokers can achieve better results in quitting smoking. The daily average smoking amount is the main factors affecting smoking cessation.
