P3.06-005 - Attitudes and Beliefs Toward Lung Cancer Screening Among Older Smokers (ID 1724)
09:30 - 09:30 | Author(s): J.K. Cataldo
- Abstract
Background:
Lung cancer (LC) is the leading cause of cancer in the U.S. with 85% caused by smoking. There is recent strong evidence that LC mortality is decreased by 20% with low-dose computed tomography (LDCT) screening for healthy individuals with an elevated risk for lung cancer. Previous studies have shown that those at higher risk (i.e., older smokers) are less interested in being screened despite awareness of risk.
Methods:
The aims for this study were, among older smokers: 1) Identify the demographics, smoking history, knowledge, and attitude factors associated with willingness to have a CT scan and 2) Provide a predictive model of factors to explain willingness to have a CT scan. This was a cross-sectional national survey study with 549 older adult (≥ 45 years) current and former smokers (≤ 2 years quit).
Results:
There were no significant differences between current and former smokers on all variables. After controlling for age, gender, ethnicity, income and education, all perception and belief variables significantly associated with agreement to have a LDCT scan were included in a logistic regression analysis to develop a predictive model for agreement to have a LDCT scan.

Conclusion:
Older smokers are interested in LC screening and overall, their attitudes are positive. Eleven variables had a significant association with the decision to have a CT scan. In the final model, four beliefs were significant predictors of whether older smokers would agree to a scan. The strongest predictor was “believes that early detection of LC will result in a good prognosis,” followed by perception of accuracy, belief that they are at high risk for LC, and belief it will decrease worry about LC. An effort needs to be made to improve smokers’ knowledge of the potential benefits and risks when they are making decisions about participation in screening.
