减少健康和灾害风险是建设智慧城市的重要和必要组成部分，特别是在气候变化可能增加极端气温发生频率和城市居民健康风险的情况下。然而，关于传播天气警报和健康保护信息的最佳方式的知识有限。这项研究探讨了香港公众获取天气信息的模式，并研究了这些模式的社会人口预测因素，以确定智慧城市发展对公共卫生的潜在影响。本研究于2016年年初，以人口为基础，以分层、横截面、随机数字拨号的方式，对香港15岁以上操粤语的人口进行电话调查。分析基于1017个有效样本，响应率为63.6%。寒冷天气警告在香港广泛传播，95.7%的受访者表示知道公众警告。电视和智能手机应用程序是获取天气信息的两个最重要渠道。年龄和教育水平是与智能手机技术的当前使用和未来偏好相关的主要社会人口变量。在不使用首选渠道获取天气信息的受访者中，61.3%的人考虑改用智能手机应用程序。此外，智能手机应用程序使用者和非使用者之间的个人健康保护措施和自我报告的健康影响模式存在显著差异。天气信息的传播应适合用户的社会人口特征。
Health and disaster risk reduction are important and necessary components in building a smart city, especially when climate change may increase the frequency of extreme temperatures and the health risks of urban dwellers. However, limited knowledge is available about the best way to disseminate weather warnings and health protection information. This study explores the weather information acquisition patterns of the Hong Kong public and examines the sociodemographic predictors of these patterns to establish the potential public health implications of smart city development. A population-based, stratified cross-sectional, random digit dialing telephone survey was conducted among the Cantonese-speaking population aged over 15 years in Hong Kong in early 2016. Analyses were conducted based on 1017 valid samples, with a response rate of 63.6%. Cold Weather Warnings were well disseminated in Hong Kong, with 95.7% of the respondents reporting awareness of the public warnings. Television and smartphone apps were the two most important channels for weather information acquisition. Age and education level are the main social-demographic variables associated with the current utilization and future preference of smartphone technology. Among those who were not using a preferred channel to acquire weather information, 61.3% considered switching to a smartphone app. Moreover, the patterns of individual health protection measures and self-reported health impacts were significantly different between smartphone app users and non-users. Weather information dissemination should be tailored to the sociodemographic characteristics of the users.
