Identification of vulnerable population to climate changes and establishment of effective preventive strategies

为了评估环境温度对发病率的影响，我们利用2006 - 2010年冈山市65岁及以上老年人的紧急救护车调度数据进行了时间序列分析。在对包括悬浮颗粒物和臭氧在内的多种协变量进行调整后，我们发现在热环境下呼吸系统疾病（特别是肺炎和流感）的调整率比增加。相比之下，在寒冷环境下，心血管疾病（特别是短暂性脑缺血发作）的调整后发病率增加。

To evaluate the impact of ambient temperature on morbidity, weconducted a time-series analysis by using the daily data of emergency ambulance dispatches for people aged 65 or older from 2006 to 2010 in Okayama city. After adjusting for a variety of covariates including suspended particulate matter and ozone, we found that an adjusted rate ratio for respiratory diseases (particularly, pneumonia and influenza) increased under heat environment. By contrast, an adjusted rate ratio for cardiovascular diseases (particularly, transient ischemic attack) increased under cold environment.
