背景:非洲城市,特别是阿比让和约翰内斯堡,面对城市快速增长的挑战,非正式和紧张的卫生服务,气候变化导致温度升高。这项研究旨在了解这些城市与热相关的健康影响的复杂性。目标是:(1)使用健康绘制城市内热风险和暴露图,社会经济,气候和卫星图像数据;(2)建立分层热健康预测模型,以预测不良健康结果;(3)建立早期预警系统,以及时发出热浪警报。最终目标是培育具有气候适应性的非洲城市,保护不成比例的受影响人群免受热危害。
方法:该研究将从2000年至2022年在约翰内斯堡和阿比让进行的合格成人临床试验或队列研究中获取健康相关数据集。将收集更多数据,包括社会经济,气候数据集和卫星图像。这些资源将有助于绘制热危害图并量化热健康暴露,风险和发病率升高的程度。结果将使用先进的数据分析方法来确定,包括统计评估,机器学习和深度学习技术。
背景:该研究已获得Wits人类研究伦理委员会的批准(参考号:220606)。数据管理将遵循批准的程序。结果将通过讲习班传播,社区论坛,会议和出版物。将根据道德和安全考虑制定数据存储和管理计划。
BACKGROUND: African cities, particularly Abidjan and Johannesburg, face challenges of rapid urban growth, informality and strained health services, compounded by increasing temperatures due to climate change. This study aims to understand the complexities of heat-related health impacts in these cities. The objectives are: (1) mapping intraurban heat risk and exposure using health, socioeconomic, climate and satellite imagery data; (2) creating a stratified heat-health forecast model to predict adverse health outcomes; and (3) establishing an early warning system for timely heatwave alerts. The ultimate goal is to foster climate-resilient African cities, protecting disproportionately affected populations from heat hazards.
METHODS: The research will acquire health-related datasets from eligible adult clinical trials or cohort studies conducted in Johannesburg and Abidjan between 2000 and 2022. Additional data will be collected, including socioeconomic, climate datasets and satellite imagery. These resources will aid in mapping heat hazards and quantifying heat-health exposure, the extent of elevated risk and morbidity. Outcomes will be determined using advanced data analysis methods, including statistical evaluation, machine learning and deep learning techniques.
BACKGROUND: The study has been approved by the Wits Human Research Ethics Committee (reference no: 220606). Data management will follow approved procedures. The results will be disseminated through workshops, community forums, conferences and publications. Data deposition and curation plans will be established in line with ethical and safety considerations.
