title: [Relationship between age and smoking abstinence self-efficacy].
abstract: OBJECTIVE
  To investigate the relationship between smoking abstinence self- efficacy (SASE) and age.
  
  
  METHODS
  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.
  
  
  RESULTS
  The relationship between SASE and age showed a U-shaped curve with the nadir at 60 years old.
  
  
  CONCLUSIONS
  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.
