Spatial pattern assessment of dengue fever risk in subtropical urban environments
Impact of alcohol taxes on violence in Hong Kong
BACKGROUND: Interpersonal violence is a major public health concern with alcohol use a known risk factor. Despite alcohol taxation being an effective policy to reduce consumption; Hong Kong, contrary to most developed economies, embarked on an alcohol tax reduction and elimination policy. METHODS: To assess the impact of the alcohol tax reductions, we analysed population-based hospitalisation data for assault from the Hong Kong Hospital Authority…
Childhood Wheeze, Allergic Rhinitis, and Eczema in Hong Kong Isaac Study from 1995 to 2015
There was an increase in the prevalence of wheezing, allergic rhinitis, and eczema across the surveys. The most important associated risk factor identified was the increased prevalence of a parental history of atopy
Cause-specific mortality attributable to cold and hot ambient temperatures in Hong Kong
Source-Specific Volatile Organic Compounds and Emergency Hospital Admissions for Cardiorespiratory Diseases
Knowledge gaps remain regarding the cardiorespiratory impacts of ambient volatile organic compounds (VOCs) for the general population. This study identified contributing sources to ambient VOCs and estimated the short-term effects of VOC apportioned sources on daily emergency hospital admissions for cardiorespiratory diseases in Hong Kong from 2011 to 2014. We estimated VOC source contributions using fourteen organic chemicals by positive matrix …
Five-year lung cancer mortality risk analysis and topography in Xuan Wei
Xuan Wei lung cancer mortality has increased continuously since the third national retrospective surveys on the causes of death by the Ministry of Health of the People's Republic of China (2004-2005), especially for local women and residents over 35 years of age. Geographically, lung cancer in Xuan Wei showed unique spatiotemporal clustering. The local lung cancer mortality was significantly correlated with the smoky coal mine geographically. Som…
Heat Wave and Mortality
BACKGROUND: Few studies have examined variation in the associations between heat waves and mortality in an international context. OBJECTIVES: We aimed to systematically examine the impacts of heat waves on mortality with lag effects internationally. METHODS: We collected daily data of temperature and mortality from 400 communities in 18 countries/regions and defined 12 types of heat waves by combining community-specific daily mean temperature ≥90…
Addressing the source contribution of PM 2.5 on mortality
We estimated PM _2.5 concentrations using satellite data and population mortality values for cause-specific diseases and employed the integrated exposure–response model to obtain the associations between exposure and response. PM _2.5 source apportionment data were then used to evaluate the excess mortality attributable to PM _2.5 from different emission sources. In 2013, 1.07 million excess deaths were attributed to PM _2.5 exposure in China. Th…
Associations of PM2.5 and Black Carbon with Hospital Emergency Room Visits during Heavy Haze Events
In January 2013, severe haze events over northeastern China sparked substantial health concerns. This study explores the associations of fine particulate matter less than 2.5 μm (PM 2.5 ) and black carbon (BC) with hospital emergency room visits (ERVs) during a haze season in Beijing. During that period, daily counts of ERVs for respiratory, cardiovascular and ocular diseases were obtained from a Level-3A hospital in Beijing from 1 December 2012 …
Global Variation in the Effects of Ambient Temperature on Mortality
BACKGROUND: Studies have examined the effects of temperature on mortality in a single city, country, or region. However, less evidence is available on the variation in the associations between temperature and mortality in multiple countries, analyzed simultaneously. METHODS: We obtained daily data on temperature and mortality in 306 communities from 12 countries/regions (Australia, Brazil, Thailand, China, Taiwan, Korea, Japan, Italy, Spain, Unit…
Impacts of alcohol duty reductions on cardiovascular mortality among elderly Chinese
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 average intervention time series analyses were applied to monthly morality data from 2001 to 201…
Institutional risk factors for norovirus outbreaks in Hong Kong elderly homes
Elderly home capacity, staff-to-resident ratio and wheelchair accessibility were risk factors for norovirus outbreaks in Hong Kong elderly homes. Partitions between beds were a protective factor of norovirus outbreaks. These results should be considered in the infection control in Hong Kong elderly homes
Hospitalizations for varicella in children and adolescents in a referral hospital in Hong Kong, 2004 to 2008
Varicella can lead to serious complications and prolonged hospitalization, even in previously healthy children. Lower relative humidity in cool seasons is associated with higher number of paediatric varicella hospital admissions. These findings are useful for a better understanding of the pattern of paediatric varicella hospitalization in Hong Kong
Time series analysis of dengue fever and weather in Guangzhou, China
Minimum temperature and minimum humidity, at a lag of one month, are positively associated with dengue incidence in the subtropical city of Guangzhou, China. Wind velocity is inversely associated with dengue incidence of the same month. These findings should be considered in the prediction of future patterns of dengue transmission
Nanoquartz in Late Permian C1 coal and the high incidence of female lung cancer in the Pearl River Origin area
The high incidence rate of lung cancer in Xuan Wei, one of the counties in the current study area, was once attributed to high indoor air concentrations of PAHs. The research results have been cited for qualitative and quantitative cancer risk assessment of PAHs by the World Health Organization and other agencies. If nanoquartz is found to be the main underlying cause of the lung cancer epidemic in the study area, cancer potency estimates for PAH…
