Beliefs and Intentions to Undergo Lung Cancer Screening among Korean Males / Journal of the Korean Cancer Association, 대한암학회지

ABSTRACT

PURPOSE: Low-dose computed tomography (LDCT) has been reported as an effective screening method for lung cancer in high-risk populations. We aimed to examine willingness to be screened among Korean males using LDCT and to determine factors associated with lung cancer screening intentions (LCS) based on the Health Belief Model (HBM). MATERIALS AND METHODS: Data were obtained from the 2015 Korean National Cancer Screening Survey, a cross-sectional survey that utilized nationally representative random sampling. The survey included 1,730 male participants 40-74-year-old. Respondents were questioned regarding their willingness to undergo LCS and components of HBM. Factors associated with intentions to undergo screening were explored using logistic regression. RESULTS: Among participants, 65.2% were current smokers. Among high-risk subjects, 60.6% of men reported intentions to undergo LCS, compared to 49.9% of average-risk males. Men with higher perceived susceptibility in the average- and high-risk groups were, respectively, 1.63 (95% confidence interval [CI], 1.39 to 1.91) and 2.30 (95% CI, 1.14 to 4.63) times more likely to intend to undergo LCS compared to those with lower perceived barriers. Also, men in the average- and high-risk groups with higher perceived barriers to screening were, respectively, 0.79 (95% CI, 0.68 to 0.91) and 0.52 (95% CI, 0.29 to 0.92) times less likely to intend to undergo LCS compared to those with lower perceived barriers. CONCLUSION: Tailored interventions designed to promote accurate perceptions of susceptibility and risk, as well as to reduce perceived barriers to screening, may effectively increase adherence to recommendations for LCS among high-risk Korean men.
