Abstract

Background: Heatwave warnings provide crucial information about the nature of the event and the steps that can be taken to mitigate its impact. It is well known that heat events disproportionately impact the health of older adults. Therefore, it's critical that heatwave warnings reach this population. However, our current understanding of the effectiveness of heatwave warning messages among older Queenslanders is limited.

Methods: A Queensland wide survey was conducted in 2022 among 547 older adults (≥65 years), aiming to collect information on their perception of heat-related health risk, their knowledge of the existing heatwave warnings, and if they had ever heard of a heatwave warning. Chi-square analysis followed by multinomial or binomial logistic regression was utilized to understand various socio-economic and personal factors that impact the heatwave warning reach to older Queenslanders.

Results: Only 43% of the respondents had heard a heatwave warning and only 49% of those who heard a warning(s) changed their behavior as a result. The results showed 20% of respondents perceived themselves to be at heat-related health risk, and these individuals were 1.98 times more likely to have heard heatwave warnings. Further, individuals who perceived themselves to be at heat-related health risk were 3.62 times more likely to adopt adaptive measures in response to heatwave warnings.

Implications: This study suggests that in older adults, higher knowledge and perception of heat-related health risk are associated with higher likelihoods of attention to heatwave warnings and adoption of cooling measures.

改进针对老年人的热浪预警:澳大利亚昆士兰州的案例。
背景:热浪警报提供了有关热浪性质的重要信息,以及可以采取哪些措施来减轻热浪的影响。众所周知,热浪对老年人的健康影响更大。因此,让这部分人群了解热浪预警至关重要。然而,我们目前对热浪预警信息在昆士兰老年人中的效果了解有限:2022 年,昆士兰州对 547 名老年人(≥65 岁)进行了一次广泛调查,旨在收集他们对热相关健康风险的看法、对现有热浪警告的了解以及是否听说过热浪警告等信息。利用卡方分析(Chi-square analysis)和多项式或二项式逻辑回归(multinomial or binomial logistic regression)来了解影响昆士兰州老年人对热浪警告知晓率的各种社会经济和个人因素:只有 43% 的受访者听到过热浪警告,而在听到警告的受访者中,只有 49% 的人因此改变了自己的行为。结果显示,20% 的受访者认为自己面临与热有关的健康风险,而这些人听到热浪警告的可能性要高出 1.98 倍。此外,认为自己面临与热有关的健康风险的人在听到热浪警告后采取适应性措施的可能性是其他人的 3.62 倍:这项研究表明,对于老年人来说,对热相关健康风险的了解和感知越多,关注热浪警告和采取降温措施的可能性就越高。
