RESUMO
Objective:To investigate the effects of educational level on smoking cessation in patients with moderate to severe tobacco dependence, explore effective individualized smoking cessation methods, and increase smoking cessation rate.Methods:A total of 480 patients with moderate to severe tobacco dependence who were willing to quit smoking and received treatment in the Department of Respiratory and Critical Care Medicine, Shengli Oilfield Central Hospital from January to December 2020 were included in this study. They were divided into four groups ( n = 120/group) according to their educational level: group A (elementary school and below), group B (junior high school and senior high school), group C (technical secondary school or college), and group D (university and above). All patients were randomly assigned to undergo "5A" intervention alone or "5A" intervention combined with varenicline intervention (combined intervention). Patients' awareness of the health risks of tobacco smoking was compared among the four groups. The smoking cessation rate measured at different time points was compared between different intervention strategies. Results:The scores of health risk of tobacco smoking in groups D, C, B, and A were (806.5 ± 35.7) points, (710.8 ± 26.2) points, (643.6 ± 43.4) points, and (512.4 ± 30.1) points, respectively. Patients with high education levels had high awareness of the health risk of tobacco smoking ( F = 1 543.26, P < 0.001). At 1, 3, and 6 months, the smoking cessation rate of combined intervention was higher than that of "5A" intervention alone in each group (group A: χ2 = 3.85, 4.23, 4.10, group B: χ2 = 4.30, 4.09, 4.60, group C: χ2 = 6.81, 4.30, 4.03, group D: χ2 = 6.71, 6.51, 4.73, all P < 0.05). The smoking cessation rate after 6 months of "5A" intervention alone or combined intervention in group D was 60.0% and 78.3% respectively, which were significantly higher than 41.7% and 60.0% in group C, 23.3% and 41.7% in group B, and 20.0% and 36.7% in group A ( χ2 = 26.59, 26.12, both P < 0.001). At different time points, the smoking cessation rates of the "5A" intervention alone in group D were significantly higher than those of combined intervention in groups A and B ( χ2 = 9.25, 25.04, 7.29, all P < 0.05). Conclusion:Awareness of the health risks of tobacco smoking is related to a patient's educational level, and affects smoking cessation. Individualized smoking cessation interventions based on a patient's educational level can increase the rate of smoking cessation.
