Public awareness and knowledge of liver health and diseases in Singapore

Abstract

Background and Aim: Despite efforts in controlling and managing liver diseases, significant health issues remain. This study aims to evaluate the degree of public awareness and knowledge regarding liver health and diseases in Singapore. Methods: A cross-sectional, self-reported, web-based questionnaire was administered to 500 adult individuals. Questionnaire items pertained to knowledge and awareness of overall liver health, liver diseases and their associated risk factors. Results: Sixty-four percent of respondents were ≥35 years old and 54.0% were male. While majority agreed that regular screening was important for liver health (91.2%), only 65.4% attended health screening within recent 2 years. Hepatitis B had more awareness than hepatitis C among the respondents. About 70% agreed the consequences of viral hepatitis included liver cirrhosis, failure, and/or cancer. Yet, only 15% knew hepatitis C is not preventable by vaccination and more than half mistaken hepatitis B and C are transmissible via contaminated or raw seafood. Despite 75% being aware of non-alcoholic fatty liver disease, many were not aware of the related risk factors and complications. Awareness of specific screening and diagnostic tests for liver health was poor as one-fifth correctly identified the diagnostic tests for viral hepatitis. Preferences for doctor's consultation, TV, or newspapers (online) as information channels contrasted those currently used in the public health education efforts. Conclusions: The levels of understanding of liver diseases, risk factors, and potential complications are suboptimal among the Singapore public. More public education efforts aligned with respondents' information-seeking preferences could facilitate addressing misperceptions and increase knowledge about liver diseases.
