Abstract
The extreme heat wave in Australia in 2009 resulted in significantly increased number of daily deaths The circumstances that lead to deaths during extreme heat have not been explored before in Australia This study aims to identify the individual and community risk factors for deaths during this extreme heat wave in Adelaide A matched casecontrol study was conducted Cases were those who died in the Adelaide metropolitan area during the heat wave period For each case two community controls were randomly selected matched by age and gender Facetoface or telephone interviews were conducted to collect data of demographic information living environment social support health status and behavioural changes during the heat wave Descriptive analysis as well as simple and multiple conditional logistic regressions were performed In total 82 deaths and 164 matched community controls were included in the analysis with a median age of 775 range 266–1007 The multiple logistic regression model indicated that compared with controls the risk of death during the heat wave was significantly increased for people living alone AOR = 4231 95 CI 23 7928 or having existing chronic heart disease AOR = 224 95 CI 17 3030 In addition having air conditioning in bedrooms AOR = 0004 95 CI 000006 028 and participating in social activities more than once a week AOR = 0011 95 CI 00004 029 indicated significant protective effects We have identified factors that could significantly impact on the likelihood of deaths during heat waves Our findings could assist in the development of future intervention programs and policies to reduce mortality associated with a warmer climateThe study was supported by the Australian Research Council Linkage Project LP110200820 to PBI et al and the Department for Health and Ageing SA Dr Ying Zhang was an Australian National Health and Medical Research Council Public Health Training Fellow 602749This project was approved by the Human Research Ethics Committees HREC from both the University of Adelaide H1012010 and the South Australian DHA 376/06/2013 Due to the ethical sensitivity of the study work was carried out within the DHA in SA as required by the ethical approvals In order to collect deceased patients’ data from the hospitals’ medical records ethical approvals were also obtained from each Ethics Committee of relevant hospitals Consent from subjects participating in the study was received prior to conducting the study
