Associations between Health Literacy, Cancer-Related Knowledge, and Preventive Health Behaviors in Community-Dwelling Korean Adults

초록

This cross-sectional study aimed to examine the association between health literacy, cancer-related knowledge, and preventive health behaviors among community-dwelling adults in Korea. Data were collected from 542 adults aged >= 18 years living in five big provinces in Korea (Seoul, Gyeonggi-do, Gyeongsang-do, Chungcheong-do, and Gangwon-do). Socio-demographic and health-related characteristics were determined using structured questionnaires. Health literacy, cancer-related knowledge, and engagement in preventive health behaviors were measured using validated instruments. These three variables differed according to socio-demographic and health-related characteristics, such as education, sex, age, and marital status. In the hierarchical regression analysis, health literacy (beta = 0.26, p<.001) and cancerrelated knowledge (beta = 0.21, p<.001) were significant predictors of preventive health behavior after adjusting for confounding variables. Cancer-related knowledge partially mediated the effect of health literacy on preventive health behaviors. Health literacy can play a key role in cancer prevention. It is important for healthcare providers to know how to deliver cancer-related knowledge and how to help people with low health literacy to engage in preventive health behaviors, using a variety of health information resources. Further research is needed to develop the instruments to assess comprehension of spoken and written health messages for cancer prevention and screening.
