Purpose: Many patients presenting for lung cancer screening are current smokers; screening may be a teachable moment for cessation. The objective of the current analysis is to compare cessation readiness among lung screening patients by rural/urban residence and race/ethnicity to identify populations who may benefit from tailored support. Methods: We enrolled 1,095 current smokers presenting for low dose CT lung cancer screening at 24 NCI Community Oncology Research Program (NCORP) imaging clinics as part of the OaSiS trial (WF 20817CD). Prior to screening, we collected data regarding perceived risk and worry about lung cancer, perceived impact of cessation on lung cancer risk, cessation readiness, and quitting self-efficacy (both 1-10 Likert type scales). We classified participants as rural vs urban using the zip-code-based definitions of the Federal Office of Rural Health Policy. We summarized group differences using chi-square analyses. Results: Participants were 50.2% female; average age 64 years (range 55-79); 81.9% non-Hispanic White (NHW), 13.3% non-Hispanic Black (NHB), 2.6% Hispanic, 2.2% American Indian; 20.2% rural residence). The median cigarettes smoked per day was 20 and the median pack years smoked was 44. NHW participants were less likely than other groups to report being “extremely” worried about lung cancer [15.5% vs NHB (31.4%), Hispanic (35.7%), and American Indian (25%), p&lt;.0001]. When queried about their perceived risk of developing lung cancer, NHB (21.8%), Hispanic (14.3%), and American Indian (12.5%) participants were also more likely to report that they didn’t know, compared to NHW participants (9.7%, p &lt;.0001). NHB participants were more likely to believe that quitting smoking would “very much” reduce their risk of lung cancer (52.1%), compared to NHW (36.3%), Hispanic (35.7%), and American Indian (37.5%) participants (p&lt;.001). NHWs reported lower cessation readiness compared to NHB, Hispanic, and American Indian participants (p&lt;.001). NHB and Hispanic participants also reported high quitting self-efficacy compared to NHW and American Indian participants (p&lt;.0001). With regard to rural/urban differences, compared to urban residents, rural residents reported lower or unknown perceived impact of cessation on lung cancer risk (9.5 vs 6.8% no impact & 13.2 vs 6.9% unknown, p&lt;.01). There were no other differences in cessation readiness factors by rural-urban residence. Conclusions: To advance health equity, it is important to understand cessation readiness, among patients presenting to community-based imaging clinics for lung cancer screening. Evidence-based cessation treatment for racial/ethnic minorities within these settings may be enhanced by tailoring for higher cessation readiness. Rural and racial/ethnic minority patients may benefit from enhanced education regarding lung cancer risk and the impact of cessation.
