| Abstract: | BACKGROUND AND AIM: With the Westernization of the lifestyle and the rising prevalence of obesity and diabetes mellitus, non-alcoholic fatty liver disease (NAFLD) is an emerging health problem in the Asia-Pacific region. The purpose of this study was to determine the awareness of NAFLD among the general population in Hong Kong. METHODS: A random telephone survey was conducted from September 2007 to January 2008 using a structured multiple-choice questionnaire. Subjects were Hong Kong residents aged 18 or above who spoke Cantonese. RESULTS: In the first phase of the telephone survey, 521 subjects were interviewed and the results showed that as high as 83% of respondents had never come across the term 'NAFLD'. Upon completion of the second phase telephone survey, a total of 508 respondents who had heard of NAFLD were successfully interviewed. Of the 508 respondents, nearly half of them (42%) expressed no idea about the prevalence of NAFLD in Hong Kong. About half of respondents (47%) knew nothing about the clinical presentation of NAFLD. The majority of them (78%) had a misconception that blood tests could provide a definite diagnosis of NAFLD. Smoking, hepatitis B carriage and a past history of hepatitis A infection were cited as risk factors of NAFLD by 52%, 57% and 42% of respondents, respectively. Of the 508 respondents who had heard of NAFLD, most of them perceived that their knowledge of NAFLD was either inadequate (46%) or highly inadequate (35%). CONCLUSION: This survey revealed an inadequate knowledge of NAFLD among the general population in Hong Kong. |
