Scanning with low-dose computed tomography reduces lung cancer mortality by 20% among high-risk individuals. Despite its efficacy, the uptake of lung cancer screening (LCS) remains low. Our study aimed to estimate state-level and nationwide LCS rates among eligible individuals and to assess disparities in LCS uptake. Data for this study were obtained from the 2022 BRFSS. Multivariable logistic regression models were used to model the associations between predictors and outcome variables and to examine LCS variability across states. Of the 28,071 participants eligible for LCS, 17.24% underwent LCS. Participants aged 65 -79 years were (OR: 1.75, 95%CI: 1.54 -1.99) more likely to undergo LCS than their younger counterparts. Those who were female (OR: 0.83, 95%CI: 0.73 - 0.94), divorced, separated, or widowed (OR: 0.85, 95%CI: 0.74-0.98), without health insurance (OR: 0.34, 95%CI: 0.22-0.53), without a primary care provider (OR: 0.29, 95%CI: 0.19-0.44), without COPD or those who did not disclose their COPD status ((OR: 0.35, 95%CI: 0.31-0.40) and (OR: 0.37, 95%CI: 0.19-0.73) respectively)) were less likely to undergo LCS than their respective counterparts. LCS uptake also varied significantly across U.S. states. We observed low uptake of LCS overall, and significant variability in LCS uptake by sociodemographic and health-related factors as well as by state of residence. The findings from this study have important implications for community health workers and healthcare clinicians and indicate the need to design effective interventions to increase LCS uptake targeting specific subgroups of populations and particular U.S. states.
