TY - JOUR PY - 2014// TI - Socio-demographic vulnerability to heatwave impacts in Brisbane, Australia: a time series analysis JO - Australian and New Zealand journal of public health A1 - Sam Toloo, Ghasem A1 - Guo, Yuming A1 - Turner, Lyle A1 - Qi, Xin A1 - Aitken, Peter A1 - Tong, Shilu SP - 430 EP - 435 VL - 38 IS - 5 N2 - OBJECTIVE: Examining the association between socioeconomic disadvantage and heat-related emergency department (ED) visits during heatwave periods in Brisbane, 2000-2008.

METHODS: Data from 10 public EDs were analysed using a generalised additive model for disease categories, age groups and gender.

RESULTS: Cumulative relative risks (RR) for non-external causes other than cardiovascular and respiratory diseases were 1.11 and 1.05 in most and least disadvantaged areas, respectively. The pattern persisted on lags 0-2. Elevated risks were observed for all age groups above 15 years in all areas. However, with RRs of 1.19-1.28, the 65-74 years age group in more disadvantaged areas stood out, compared with RR=1.08 in less disadvantaged areas. This pattern was observed on lag 0 but did not persist. The RRs for male presentations were 1.10 and 1.04 in most and less disadvantaged areas; for females, RR was 1.04 in less disadvantaged areas. This pattern persisted across lags 0-2.

CONCLUSIONS: Heat-related ED visits increased during heatwaves. However, due to overlapping confidence intervals, variations across socioeconomic areas should be interpreted cautiously. Implications: ED data may be utilised for monitoring heat-related health impacts, particularly on the first day of heatwaves, to facilitate prompt interventions and targeted resource allocation.
