Background:
As age is one of the main risk factors for lung cancer, older adults are expected to receive more messages for lung cancer screening (LCS). It is, however, unclear whether age similarly increases patient's chance of discussing LCS across various racial groups.
Objective:
To determine racial differences in the effect of patients' age on patient-physician discussion about LCS.
Methods:
This cross-sectional study borrowed data from the Health Information National Trends Survey (HINTS 2017) which included 2,277 adults. Patients' demographic factors, socioeconomic characteristics, smoking status, possible LCS indication, and patient-physician discussion about LCS were measured. We ran logistic regression models for data analysis.
Results:
Independent of possible LCS indication, older patients were more likely to have patient-physician discussion about LCS. However, there is a significant interaction between race and age, suggesting a larger effect of age on the likelihood of discussing LCS with doctors for Whites than Blacks. In race-stratified models that controlled for possible LCS indication, higher age increased lung cancer discussion for Whites but not for Blacks.
Conclusions:
Whether age increases the chance of discussing LCS or not depends on the patient's race, with Blacks receiving fewer messages regarding LCS as a result of their aging.
