Investigating the pattern of prostate specific antigen screening among E-cigarette smokers within the behavioral risk...

E-cigarettes use has recently increased, even among older individuals quitting smoking. Though past studies suggest tobacco smokers may avoid cancer screening, the relationship between e-cigarette uses and preventive health behaviors like prostate specific antigen screening is uncertain. We assessed the relationship between self-reported e-cigarette smoking and prostate specific antigen screening utilization among US adults with a history of e-cigarette use.

We included men aged 50-69 years, who provided responses regarding PSA screening receipt and smoking status, from Behavioral Risk Factor Surveillance System 2020 and 2022 surveys. Primary outcome was PSA screening receipt. Multivariable regression model was performed to investigate the association between smoking status (never-smokers, current or former e-cigarette smokers, current or former tobacco smokers) and PSA screening.

We included a weighted population of 8.1 million men aged 50-69. 2.3 million (28.3%) received PSA screening. 3.9 million (48.2%) were never-smokers. 1.3 million (16.6%) were from e-cigarettes smokers group, and 2.9 million (35.2%) were from tobacco smokers group. E-cigarettes smokers were less likely to receive PSA screening within last 2 years (0.76 [0.66-0.88]) than never-smokers. No significant difference in PSA screening was detected between never-smokers and tobacco smokers (0.91 [0.82-1.02]). E-cigarette smokers were less likely to receive PSA screening within the selected time frame (0.84 [0.72-0.97]) than tobacco smokers. When examining potential mediation by primary care visits, e-cigarette smokers were less likely to have had a check-up visit in past 2 years than tobacco smokers (0.77 [0.65-0.92]).

E-cigarette smokers were less likely to undergo PSA screening than never-smokers and tobacco smokers, possibly due to reduced use of primary care services.
