Questionnaire survey on knowledge, attitudes, and behaviour towards viral hepatitis among the Hong Kong public.

INTRODUCTION

We aimed to identify gaps in knowledge, attitudes, and behaviours towards viral hepatitis among the Hong Kong public and provide insights to optimise local efforts towards achieving the World Health Organization's viral hepatitis elimination target.

METHODS

A descriptive, cross-sectional, self-reported web-based questionnaire was administered to 500 individuals (aged ≥18 years) in Hong Kong. Questionnaire items explored the awareness and perceptions of viral hepatitis-related liver disease(s) and associated risk factors in English or traditional Chinese.

RESULTS

The majority (>80%) were aware that chronic hepatitis B and/or C could increase the risks of developing liver cirrhosis, cancer, and/or failure. Only 55.8% had attended health screenings in the past 2 years, and 67.6% were unaware of their family's history of liver diseases. Misperceptions surrounding the knowledge and transmission risks of viral hepatitis strongly hint at the presence of social stigmatisation within the community. Many misperceived viral hepatitis as airborne or hereditary, and social behaviours (casual contact or dining with an infected person) as a transmission route. Furthermore, 62.4% were aware of hepatitis B vaccination, whereas 19.0% knew that hepatitis C cannot be prevented by vaccination. About 70% of respondents who were aware of mother-to-child transmission were willing to seek medical consultation in the event of pregnancy. Gaps in knowledge as well as the likelihood of seeking screening were observed across all age-groups and education levels.

CONCLUSIONS

Comprehensive hepatitis education strategies should be developed to address gaps in knowledge among the Hong Kong public towards viral hepatitis, especially misperceptions relevant to social stigmatisation and the importance of preventive measures, including vaccination and screening, when exposed to risk factors.
