BACKGROUND & AIMS We compared the accuracy of a qualitative fecal immunochemical test (FIT) in identifying patients with proximal vs distal advanced neoplasia and evaluated whether analysis of 2 specimens performed better than analysis of 1 specimen. Distal advanced neoplasia was defined as colorectal cancer (CRC), any colorectal adenoma ≥10 mm in diameter,(More)
BACKGROUND In March 2007, the Hong Kong Government halved its heavy excise taxes on beer and wine, and 1 year later, it eliminated all duties on these beverages. This study examines the impact of such duty reductions on cardiovascular disease (CVD)-related mortality among the elderly in Hong Kong. METHODS Box-Jenkins autoregressive integrated moving(More)
Human papillomavirus (HPV) type distribution among cervical cancers and its possible changes over time are key issues that determine the cost-effectiveness of HPV vaccines. Cervical cancers diagnosed during 3 periods (1997-2007, N = 280; 1984-1986, N = 74; 1972-1973, N = 81) in Hong Kong were examined for HPV type distribution using sensitive broad-catching(More)
Human papillomavirus (HPV) 58 accounts for a notable proportion of cervical cancers in East Asia and parts of Latin America, but it is uncommon elsewhere. The reason for such ethnogeographical predilection is unknown. In our study, nucleotide sequences of E6 and E7 genes of 401 HPV58 isolates collected from 15 countries/cities across four continents were(More)
BACKGROUND The role of a faecal immunochemical test (FIT) in screening individuals with a positive family history of colorectal cancer (CRC) is not clear. AIM To assess the diagnostic accuracy of FIT using colonoscopy findings as the gold standard in identifying colorectal neoplasms. METHODS We analysed data from 4539 asymptomatic subjects aged 50-70(More)
OBJECTIVES We tested the a priori hypothesis that self-perceived and real presences of risks for colorectal cancer (CRC) are associated with better knowledge of the symptoms and risk factors for CRC, respectively. METHODS One territory-wide invitation for free CRC screening between 2008 to 2012 recruited asymptomatic screening participants aged 50-70(More)
PURPOSE to evaluate the proportion of self-referred screening participants having various psychological barriers and the factors associated with these barriers. METHODS A territory-wide bowel cancer screening centre sent an invitation via the media to all Hong Kong residents aged 50-70 years who were asymptomatic of CRC to join a free screening programme.(More)

OBJECTIVE To assess the acceptability of pre-pandemic influenza vaccination among healthcare workers in public hospitals in Hong Kong and the effect of escalation in the World Health Organization's alert level for an influenza pandemic. DESIGN Repeated cross sectional studies using self administered, anonymous questionnaires SETTING Surveys at 31(More)
BACKGROUND AND OBJECTIVES Poor adherence to medications is one of the major public health challenges. Only one-third of the population reported successful control of blood pressure, mostly caused by poor drug adherence. However, there are relatively few reports studying the adherence levels and their associated factors among Chinese patients. This study(More)
