In this paper, we present a narrative review of primary research on the health impacts of extreme weather events in urban informal settlements published between 1990 and June 2021. We include 54 studies and examine the health impacts of extreme weather events and how these were determined. We find that these events impact health directly by causing mortality, injury and disease and through indirect pathways by impacting livelihoods, access to healthcare, coping strategies and adaptive capacity. Drawing on the social determinants of health framework to frame our analysis, we find that health impacts are determined by multiple intersecting factors, relating to individual circumstances, material conditions, health status, and political and socio-economic context. Consequently, vulnerability varies between and within informal settlements. Overall, we show that responding to and minimising these health impacts requires an intersectional approach to understand and address these contextual root causes of vulnerability.

在本文中，我们对 1990 年至 2021 年 6 月期间发表的关于极端天气事件对城市非正规住区的健康影响的初步研究进行了叙述性回顾。我们纳入了 54 项研究，并检查了极端天气事件对健康的影响以及这些影响是如何确定的。我们发现，这些事件通过导致死亡、伤害和疾病直接影响健康，并通过影响生计、获得医疗保健、应对策略和适应能力的间接途径影响健康。利用健康的社会决定因素框架来构建我们的分析，我们发现健康影响是由多个交叉因素决定的，这些因素与个人情况、物质条件、健康状况以及政治和社会经济背景有关。因此，非正规住区之间和内部的脆弱性各不相同。总体，
