Understanding Factors Associated with Uptake of Lung Cancer Screening among Individuals at High Risk

Early detection using low-dose computed tomography scanning reduces lung cancer-specific mortality by 20% among high-risk individuals. Despite its efficacy, the uptake of lung cancer screening (LCS) remains low. This study aimed to identify factors associated with the uptake of LCS in high-risk individuals. Data for this study were obtained from the Behavioral Risk Factor Surveillance System (n=11,297). Multivariable logistic regression models were used. Individuals with no health insurance (OR: 0.33, 95% CI: 0.19-0.58), no primary health care provider (OR: 0.40, 95% CI: 0.25-0.64), no chronic obstructive pulmonary disease (OR: 0.37, 95% CI: 0.28- 0.49), and racial/ethnic minorities other than Black and Hispanic (OR: 0.49, 95% CI: 0.31-0.78) were less likely to participate in annual LCS. Low-dose computed tomography uptake varied widely across the 24 U.S. states. The findings from this study have important implications for designing more effective interventions to target specific U.S. states and subgroups for the uptake of annual LCS.
