Relationship between age and smoking abstinence self-efficacy / 中华流行病学杂志

<p><b>OBJECTIVE</b>To investigate the relationship between smoking abstinence self- efficacy (SASE) and age.</p><p><b>METHODS</b>A cross-sectional questionnaire survey in form of face-to-face interview was performed. The SASE level was assessed by using the Smoking Abstinence Self-Efficacy Scale. Univariate two-degree fractional polynomials (FPs) regression model was used to explore the relationship between SASE and age after adjusting of potential confounders: marital status, occupation and education.</p><p><b>RESULTS</b>The relationship between SASE and age showed a U-shaped curve with the nadir at 60 years old.</p><p><b>CONCLUSION</b>The distribution of SASE is not consistent among age groups; middle aged person has lower level of SASE than both the younger and the elder.</p>

Mediating effect of smoking abstinence self-efficacy on association between awareness of smoking hazard and successful smoking cessation / 中华流行病学杂志

<p><b>OBJECTIVE</b>To estimate the mediating effect of smoking abstinence self-efficacy (SASE) on the association between awareness of smoking hazard and successful smoking cessation.</p><p><b>METHODS</b>A community-based case-control study was conducted in 642 smokers who successfully stopped smoking, and 700 smokers who failed in smoking cessation were used as controls. The awareness of smoking hazard was evaluated by total score of 12 items. The SASE was assessed by using Smoking Abstinence Self-Efficacy (ASES-S). The total effect was classified as direct effect and indirect effect through logistic regression analysis based on the KHB method.</p><p><b>RESULTS</b>After adjusting the potential confounders, including age, age of smoking initiation, occupation, educational level and marital status, the mediating effect of SASE accounted for 6.03% among the total effect of awareness of smoking hazard in those who successfully stopped smoking while the direct effect accounted for 93.97% among the total effect. In the three specific situation of SASE, the mediating effect of SASE accounted for 6.80% (positive/social situations), 3.08% (negative/affective situations) and 2.32% (habit/addictive situations) among the total effect, respectively.</p><p><b>CONCLUSION</b>SASE has part mediating effect to influence on the association between the awareness of smoking hazard and successful smoking cessation. Improving smokers' awareness of smoking hazard may not only promote successful smoking cessation directly, but also contribute to quit smoking through improving the score of SASE.</p>
