Abstract Body:
Background. Lung cancer is the second most common malignancy in the United States. Although epidemiological studies suggest lung cancer screening may benefit people with a long-term smoking history, limited studies investigated the knowledge, awareness, and intention of lung cancer screening. Methods. We used 2015 and 2017 Health Information National Trends Survey (HINTS) data to investigate associations between sociodemographic and health-related factors and a history of communication with physician about lung cancer screening. A multivariable logistic regression was used to calculate adjusted odds ratio (aOR) and 95% confidence interval (CI) of each factor. Additionally, we examined if there was an interaction between chronic lung or heart disease and gender or smoking history. Results. A total of 3,785 people were included for analysis and 262 of them had a history of communication (weighted%: 5.6). Overall, about one-third (31.7%) of participants were aged≥65 years, over half were female (52.8%), and 81.2% were white. The multivariable logistic regression found older age, being a male, other race (non-white, non-black), having a clinical checkup last year, having a history of smoking, and chronic lung disease were significantly and positively associated with the history of communication. We observed significant interactions between chronic lung disease and sex (p-interaction=0.02) or smoking history (p-interaction=0.01), effect measures of chronic lung disease were positive and more substantial in male (aOR=3.55, 95%CI 2.10-6.00) and people with a history of smoking (aOR=3.18, 95%CI 2.02-5.03). Conclusion. In conclusion, we identified 6 factors associated with communication with physician about lung cancer screening and potential modification effects by sex and smoking history. These can be helpful for health practitioners to establish a more targeted program to increase knowledge and awareness of lung cancer and relevant screening options.
