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)
BACKGROUND Hypertension is the most important risk factor for cardiovascular diseases. Little information exists on the status of hypertension among southern Chinese. We therefore investigated the hypertension prevalence, awareness, treatment, control, and associated factors in a southern Chinese population with 85 million residents. METHODS Stratified(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)

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 & 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 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)
BACKGROUND Macau has recently experienced expansive socioeconomic growth, leading to lifestyle changes that could have contributed to the development of certain diseases. Little information exists on the prevalence of metabolic syndrome (MetS) and associated risk factors. This information is important, since the management of MetS is tightly connected with(More)
BACKGROUND Preferences to choose immunochemical faecal occult blood test (FIT) and colonoscopy as colorectal cancer (CRC) screening modalities among asymptomatic Chinese subjects remain unknown. AIM To evaluate the preference of choosing colonoscopy vs. FIT among CRC screening participants. METHODS From a community-based CRC screening programme for(More)
BACKGROUND A need for quadrivalent vaccines to cover both lineages of influenza B has been raised. Information on the circulation status of influenza B lineages and the associated hospitalization rates is important to assist evidence-based decision making. This retrospective study revealed the situation in a subtropical city over a 10-year period. METHODS(More)
