Cancer information seeking and scanning behavior among Nepalese migrants in Japan and its association with preventive behavior

BACKGROUND: Increasing attention is being paid to cancer information seeking (CISE) (active searching for cancer-related health information) and information scanning (CISC) (passive collection of cancer-related health information) among migrants. However, information is lacking with respect to the extent and distribution of CISE and CISC among migrants, particularly in Japan. This study aimed to evaluate the prevalence of both CISE and CISC, to clarify factors associated with CISE and CISC, and to elucidate the association of CISE and CISC with basic cancer knowledge and preventive behavior among Nepalese migrants living in Tokyo, Japan. METHODS: Nepalese migrants living in Tokyo were recruited from March to August 2019, with snowball sampling. We collected data on CISE, CISC, sociodemographic components, health-related factors, knowledge about risk factors for cancer, and cancer-prevention behavior using a structured questionnaire. We employed several regression approaches to fulfill our study objectives. RESULTS: Out of the total 200 participants, 53 (27%) were actively involved in CISE and 176 (88%) in CISC. Internet was the most common information source. High education level and Japanese language skills were positively associated with both CISE and CISC. Migrants with low perceived health status were more likely to perform CISC, while those who had been ill last year and who perceived proper access to doctors were more likely to undertake CISE. Migrants with high CISE (B = 0.10, 95% CI: 0.01, 0.19) and high CISC (B = 0.16, 95% CI: 0.08, 0.23) were more likely to have better knowledge on risk factors of cancer. Furthermore, migrants with high CISE were more likely to eat fruits (B = 0.17, 95%CI: 0.01, 0.32), undergo pap smear test (OR = 1.72, 95%CI: 1.12, 2.65), and colonoscopy (OR = 6.02, 95%CI: 1.63, 22.13). CONCLUSION: In this study, the proportion of Nepalese migrants who deliberately undertook CISE was low, while the practice of CISC was relatively common. Given that the CISE was associated with cancer-prevention behavior, proper strategies should be implemented to alleviate barriers for CISE and improve its impact on providing reliable evidence about cancer to migrants in Japan.
