Abstract Background: Lung cancer screening (LCS) via low-dose computed tomography (LDCT) can reduce mortality through early detection. However, conversations between providers and eligible patients remain uncommon, particularly among racial and ethnic populations. To help reduce race/ethnic disparities, LCS eligibility was expanded in 2021 to include adults aged 50–80 with at least a 20-pack-year smoking history. This study examines racial and ethnic differences in provider-initiated discussions about LCS among U.S. adults aged 50-80 with a smoking history. Methods: This cross-sectional study used national data from the 2022–2024 Health Information National Trends Survey (HINTS). The sample included adults aged 50-80 with current or former smoking history (n = 1,452). The outcome was whether a provider initiated a conversation about LCS in the past year. We used logistic regression to examine associations between race/ethnicity and provider-initiated discussions, controlling for sociodemographic and health-related covariates. Results: Hispanics had significantly lower odds of reporting a LCS discussion compared to non-Hispanic Whites (AOR = 0.53, 95% CI: 0.30–0.94). Those with three or more provider visits (AOR = 1.94, 95% CI: 1.32–2.86) and those with depression (AOR = 1.43, 95% CI: 1.02–2.01) had higher odds of reporting LCS discussions compared to their counterparts. Former smokers were less likely than current smokers to report such discussions (AOR = 0.30, 95% CI: 0.21–0.42). Conclusion: Despite expanded eligibility, disparities persist in provider-initiated conversations about LCS, especially for Hispanics. Because the dataset lacked smoking history, future research should collect this information to assess if disparities stem from lower pack-years among Hispanics. Equity-focused interventions, such as culturally tailored strategies and system-level prompts, may help ensure that all eligible individuals are adequately informed about LCS options.
