Coronary artery disease (CAD) is the third most prominent cause of death globally, and smoking is the most common risk factors for CAD. However, few studies have examined both smoking and smoking cessation intentions in patients with CAD. The study aims to explore the predictors for smoking and quitting intentions among male CAD patients. This was a cross-sectional study. A total of 368 male CAD patients were recruited and classified into never smoked, quit smoking, and continuing to smoke three groups. Demographic information, level of nicotine dependence, carbon monoxide concentration, depression, and resilience were analyzed by using t-test, one- way analysis of variance (ANOVA), and least significant difference (LSD) post-hoc test and the multiple logistic regression analysis. The results revealed that among participants, 23.1% had never smoked, 40.5% had quit smoking, and 36.4% continued to smoke. Multiple logistic regression analysis revealed that age (OR=0.95, 95% CI=0.90–0.99), carbon monoxide (OR=1.74, 95% CI=1.51–2.01), and depression (OR=1.13, 95% CI=1.04–1.23) predicted participants who continued to smoke. Among the 134 participants who continued to smoke, 35.8% exhibited no intention to quit, and 64.2% planned to quit. Nicotine dependence (OR=0.79, 95% CI=0.66–0.94) and depression (OR=1.10, 95% CI=1.02–1.20) were significant predictors in participants who intended to quit smoking. The study demonstrates that depression is a significant predictor for both smoking and quitting intentions among male CAD patients.
Chronic obstructive pulmonary disease (COPD) is the main cause of death among people aged 65 years and above. Smoking cessation reduces the risk of morbidity and mortality. This study used the variables of smoking cessation behavior and psychological dependence to evaluate the effectiveness of smoking cessation shared decision-making (SDM) with traditional smoking cessation education in patients with COPD. This randomized controlled trial represents a significant positive correlation was observed among smoking duration (p<.05), the number of cigarettes (p<.05), smoking cessation behavior (p<.05), and psychological cigarette dependence. The intervention group (n=44) underwent session of smoking cessation SDM, whereas the control group (n=44) underwent session of traditional smoking cessation education. After three months of the intervention, significant improvements in psychological cigarette dependence (p<.05) and smoking cessation behavior (p<.05) were observed in both groups. The study confirmed that the success rate of smoking cessation in the intervention group is higher than the control group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
