Abstract

Abstract: Introduction: Adults with high-risk smoking histories benefit from annual lung cancer screening. It is unclear if there is an association between lung cancer screening and smoking cessation among U.S. adults who receive screening. Methods: We performed this population-based cross-sectional study using data from the Behavioral Risk Factor Surveillance System (2017–2020). We defined individuals eligible for lung cancer screening as adults 55–80 years old with ≥ 30 pack-year smoking history who were currently smoking or quit within the last 15 years. We assessed the association between lung cancer screening and current smoking status. Results: Between 2017 and 2020, 12, 382 participants met screening criteria. Current smoking was reported by 5685 (45.9 %) participants, of whom 40.4 % (2298) reported a cessation attempt in the prior year. Lung cancer screening was reported by only 2022 (16.3 %) eligible participants. Lung cancer screening was associated with lower likelihood of currently smoking (odds ratio [OR] 0.705, 95 % CI 0.626–0.793) compared to individuals who did not receive screening. Screening was also associated with higher likelihood of reporting a cessation attempt in the prior year (OR 1.562, 95 % CI 1.345–1.815) compared to individuals who did not receive screening. Conclusions: Receipt of lung cancer screening was associated with lower smoking rates and more frequent cessation attempts among U.S. adults. Better implementation of lung cancer screening programs is critical and may profoundly increase smoking cessation in this population at risk of developing lung cancer. Graphical Abstract: ga1 Highlights: Lung cancer screening is recommended for US adults with high-risk smoking histories. The association between screening and smoking cessation is poorly understood. From 2016 to 2020, only 16 % of eligible US adults received screening. Screening was associated with lower rates of current smoking and more frequent cessation attempts. Better implementation of screening programs in conjunction with tobacco treatment may increase smoking cessation.
