A Moderating Role of Gender in Online Health Information Seeking Behaviors for Colorectal Cancer Knowledge among Korean Americans Aged 50 to 75 Years

, &
 

ABSTRACT

Korean Americans have consistently reported the underutilization of colorectal cancer (CRC) screening, despite their high rates of CRC incidence and mortality. Research has indicated suboptimal CRC knowledge in Korean Americans as one of the main barriers to their recommended CRC screening. Also, research has shown the potential of online health information seeking (OHIS) to improve cancer knowledge and gender-based differences in the link between OHIS and cancer knowledge. Thus, this study aimed to examine the association between OHIS and CRC knowledge and the moderating effect of gender in this association among Korean Americans. A cross-sectional survey with purposive sampling was conducted of 421 Korean Americans aged 50–75 years in the Southeastern U.S. Three-step hierarchical multiple-regression analyses were performed to investigate if three blocks of variables—Block 1: control variables (sociodemographics and health-related information), Block 2: independent variables (OHIS and gender), and Block 3: an (OHIS × gender) interaction term—significantly reduce unexplained variance in CRC knowledge. The analyses showed that the final model fits best accounting for 29.3% of the variance in CRC knowledge. Also, the analyses showed that OHIS was positively associated with CRC knowledge and gender moderated the association between OHIS and CRC knowledge. The findings close the knowledge gap existing in the body of literature on the connection of OHIS to CRC knowledge in Korean Americans. The findings also extend the understanding of gender-specific approaches leveraging OHIS for CRC prevention education among Korean Americans.
