Relationship between age and smoking abstinence self-efficacy

Abstract

To investigate the relationship between smoking abstinence self- efficacy (SASE) and age. 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. The relationship between SASE and age showed a U-shaped curve with the nadir at 60 years old. 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.
