Abstract
Introduction. Lung cancer screening with low-dose computerized tomography (LDCT) is an effective and important tool to diagnose and reduce the chances of co-morbidities and lung cancer deaths. The aim of this study was to examine if any relationship exists between LDCT, chronic obstructive pulmonary disease (COPD), smoking behavior, and influenza vaccination among people between the ages of 18 to 64 years and 65 years or older.
Method. A cross-sectional research design was used in this study. A stratified random sampling method was used. The sample had 192 participants who responded to the Behavioral Risk Factors Surveillance System (BRFSS), which was used to measure participants’ responses on LDCT, COPD, smoking behavior, and influenza vaccination. Descriptive statistics, a Chi-square test of independence, and Cochran-Mantel-Haenszel test (CMH) were calculated to find relationship between these variables.
Results. There was a statistically significant association found between chronic obstructive pulmonary disease and low-dose computerized tomography (x2(1) = 8.52, p = 0.004). Among those who received an influenza vaccination, a statistically significant result was found between the relationship of chronic obstructive pulmonary disease and low-dose computerized tomography (x2(1) = 7.39, p = 0.007). However, the results suggest that LDCT may not have an influence on smoking behavior.
Discussion. Participants who undergo LDCT screening are more likely to report chronic obstructive pulmonary disease. Future research should be focused on proving a causal relationship between these variables through longitudinal or randomized controlled trial studies.
