很少有人注意到与热有关的健康影响如何随着室外温度的微城市变化而变化。这项研究探讨了位于微型城市热岛的人在炎热的夏季是否有更高的死亡风险。使用的数据包括：（1）1990-2003年6月至8月蒙特利尔（加拿大）的每日死亡率，（2）当地国际机场的每日平均室外环境温度和（3）两张热表面图像（大地卫星，红外波长）。在病例交叉设计的基础上建立了全市温度与每日死亡率的函数，该函数根据死者死亡地点的表面温度进行分层。在温暖的夏季，地表温度较高的地区的死亡风险高于地表温度较低的地区。这项研究表明，旨在降低微型城市热岛温度的措施（例如，城市绿化活动）可能会减少高温对健康的影响。需要进一步研究，以记录城市内与热有关的风险的变化，并评估旨在降低微型城市热岛温度的措施对健康的好处。
Little attention has been paid to how heat-related health effects vary with the micro-urban variation of outdoor temperatures. This study explored whether people located in micro-urban heat islands are at higher risk of mortality during hot summer days. Data used included (1) daily mortality for Montreal (Canada) for June–August 1990–2003, (2) daily mean ambient outdoor temperatures at the local international airport and (3) two thermal surface images (Landsat satellites, infrared wavelengths). A city-wide temperature versus daily mortality function was established on the basis of a case-crossover design; this function was stratified according to the surface temperature at decedents’ place of death. The risk of death on warm summer days in areas with higher surface temperatures was greater than in areas with lower surface temperatures. This study suggests that measures aimed at reducing the temperature in micro-urban heat islands (eg, urban greening activities) may reduce the health impact of hot temperatures. Further studies are needed to document the variation of heat-related risks within cities and to evaluate the health benefits of measures aimed at reducing the temperature in micro-urban heat islands.
