1 The impacts of climate change on three health outcomes The impacts of climate change on three health outcomes: temperature-related mortality and hospitalisations, salmonellosis and other bacterial gastroenteritis, and population at risk from dengue
The increase in asthma incidence, prevalence, and morbidity over recent decades presents a significant challenge to public health. Pollen is an important trigger of some types of asthma, and both pollen quantity and season depend on climatic and meteorologic variables. Over the same period as the global rise in asthma, there have been considerable increases(More)
BACKGROUND While morbidity outcomes for major disease categories during extreme heat have received increasing research attention, there has been very limited investigation at the level of specific disease subcategories. METHODOLOGY/PRINCIPAL FINDINGS We analyzed daily hospital admissions for cardiovascular (CVD), respiratory (RD), genitourinary (GU) and(More)
Background Approximately 2.5 billion people are at risk from dengue infection. Dengue is endemic to urban populations in tropical areas; large epidemics have occurred less frequently in subtropical regions, and rarely in cities in temperate regions. The virus is transmitted by the freshwater mosquito, Aedes aegypti. During the past century, surface(More)
BACKGROUND Walkability describes the capacity of the built environment to support walking for various purposes. This paper describes the construction and validation of two objective walkability indexes for Sydney, Australia. METHODS Walkability indexes using residential density, intersection density, land use mix, with and without retail floor area ratio(More)
BACKGROUND There is strong evidence based on previous studies that ethnicity and socioeconomic status are important determinants of diversity in the occurrence of diabetes. However, the independent roles of socioeconomic status, country of birth and lifestyle factors in the occurrence of type 2 diabetes have not been clearly identified. This study(More)
Humans come from a long line of meat-eaters. For much of the past two million years our hominid forebears have been evolving from scavenging to systematic hunting. This trend was intimately coupled with the evolution of the human brain, which now is much larger and more complex than was the brain of our mostly vegetarian australopithecine ancestors. In many(More)
BACKGROUND Australia has a hot climate with maximum summer temperatures in its major cities frequently exceeding 35°C. Although 'heat waves' are an annual occurrence, the associated heat-related deaths among vulnerable groups, such as older people, suggest that Australians could be better prepared to deal with extreme heat. OBJECTIVE To understand ways in(More)
BACKGROUND Climate change is expected to promote more intense and prolonged outbreaks of vector-borne disease, and alter the geographic boundaries of transmission. This has implications for the safety and supply of fresh blood products around the world. In Australia, a recent outbreak of dengue fever caused a prolonged regional shortage in the supply of(More)
