The purpose of this study was to identify factors affecting preventive behavior related to tuberculosis (TB). The focus was on knowledge, attitude and optimistic bias related to tuberculosis among university students in Korea.
A descriptive cross-sectional study was conducted with 255 students from 6 universities in 6 regions in Korea. Data were collected using a structured questionnaire online. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and multiple linear regression.
The level for scores on preventive behavior for TB was slightly good, knowledge related to TB was moderate, and attitude was good. There was a slight optimistic bias. Knowledge and attitude related to TB were positively correlated with preventive behavior for TB. The factors affecting preventive behavior for TB were attitude (β=.36,p<.001), knowledge related to TB (β=.13, p=.025). The explanatory power of these variables was 26.1% (F=10.98,p<.001).
Findings suggest that knowledge and attitude related to TB are major factors influencing preventive behavior for TB. In order to improve preventive behavior for TB, it is necessary to establish effective educational strategies and TB information media utilization that firmly enhance attitude and improve knowledge related to TB in university students in Korea.
