Summary
Asian Americans show lower adherence to annual lung cancer screening (LCS) despite eligibility. Culturally tailored strategies are needed to address disparities in early lung cancer detection for this population.
Area of Science:
- Pulmonary Medicine
- Health Disparities Research
- Oncology
Background:
- Racial disparities in lung cancer screening (LCS) persist despite expanded criteria and increased awareness.
- Existing screening guidelines and programs do not fully address the needs of all racial groups, particularly Asian Americans.
Purpose of the Study:
- To determine the annual screening adherence rate for US Preventive Services Task Force-eligible Asian American individuals undergoing LCS.
- To identify factors influencing LCS adherence among Asian American populations.
Main Methods:
- Retrospective analysis of the Jefferson LCS Program Registry (n=2,257).
- Comparison of sociodemographic and clinical data, including race and Asian American subgroups.
- Multivariate logistic regression to assess annual LCS adherence.
Main Results:
- Asian American individuals (5.4% of cohort) differed significantly in sex distribution, education, and insurance status compared to other groups.
- Lower odds of annual LCS adherence were observed in Asian American individuals (adjusted OR, 0.42; 95% CI, 0.26-0.69) after controlling for key factors.
- Asian American subgroups (Chinese, Korean, Vietnamese) exhibited distinct smoking intensity patterns.
Conclusions:
- Asian Americans in the study experienced higher rates of risk factors (e.g., low education, high smoking prevalence) and lower LCS adherence.
- There is a critical need for culturally sensitive early detection strategies to improve lung cancer outcomes for underserved Asian American populations.
